Legal documents — English–Spanish Words

Terms of use

Last updated: 10 August 2026

1. General and acceptance of these terms

Welcome to "English–Spanish Words". The Site offers a free tool for learning English and Spanish vocabulary that runs entirely in the user's browser. These terms of use, the privacy policy, the cookie and local-storage policy and the disclaimer set out on this page (together, the "Legal Documents") are reachable from a permanent link in the Site's footer and from the storage-choice banner shown on a first visit. The "Agree and save" button concerns storage on your device only; it is not acceptance of the terms and is not acceptance of the privacy policy. Use of the Site is subject to these terms. The privacy and cookie policies are notices explaining how information and device storage are handled. If you do not agree to the terms, please do not use the Site.

2. The service

The Site is a static site that runs entirely on the user's device ("client side"), with no application server, no registration and no user accounts.
The service is provided free of charge, AS IS and AS AVAILABLE, with no undertaking as to availability, continuity or freedom from faults.
The English–Spanish translations on the Site were produced with the assistance of artificial intelligence tools. AI output may contain errors, inaccuracies or translations that do not suit the context. Users should check a translation before relying on it.
The operator may change, suspend or discontinue the service, in whole or in part, at any time. Notice of a permanent discontinuation will be published on the Site a reasonable time in advance, as far as circumstances allow; temporary interruptions, maintenance and faults do not require advance notice. Because the Site has no registration and no user accounts, the operator has no way to contact users directly, and any such notice will be published on the Site itself. Discontinuation does not delete the data stored on your device — it stays in your browser, but you will not be able to use it through the Site; downloading a copy of the words you added while the service is still running is recommended.
The Site can be added to a device. The browser can put the Site on a home screen and open it in its own window, and it then works without a network as well. This is a function of the browser: it is not an application distributed through an app store, no account is created, no separate program is installed, and the service, these terms and the handling of information are exactly the same as in a browser tab. The operator publishes no app under this name in any app store and is not responsible for anything that claims to be one. Whether the option is offered at all, and what it is called, depends on the browser and the operating system, and the operator does not warrant that it will be available on any given device. Adding the app is never a condition of using the Site. It can be removed like any other app on the device; doing so may delete what the app stored there, as described in the disclaimer, clause 4.
Updating the word bank may drop data you have accumulated. The operator may add, correct, change and remove words from the bank at any time. Statistics, favourite marks and the words-to-improve list are stored per word identifier, so if a word is removed from the bank or its identifier changes, what was gathered on it is deleted from your device on the next load, without notice and with no way to restore it. The words you added yourself are not affected.

3. Content added by the user

The Site lets a user add words and translations of their own ("user content") for personal practice. That content is stored in the browser's local storage on the user's device only, is not transmitted to the operator, never reaches the operator and is not stored on any server; the operator has no access to it and no ability to view, monitor, back up or restore it. User content is not published, is not shown to any other visitor and forms no part of the Site's word bank.

Responsibility for content a user adds — for its substance, its accuracy and its lawfulness — rests with that user alone. Do not enter personal or sensitive information, login credentials, or content that is unlawful or infringes anyone else's rights into these fields. Because the content is stored in the browser only, it may be erased at any time — for instance by clearing browser data, in private browsing mode, by withdrawing consent to save on the device, or by changing device — and the operator is not responsible for its loss and cannot restore it. A user may delete their content at any time: a single word, or all words together, using the buttons on the "My words" page. That deletion is final and cannot be undone, but it deletes no other data and does not withdraw consent to save. Keeping an offline copy is recommended, using the "Download my words as a text file" button on that page, which creates a file on the user's own device; responsibility for keeping and using that file rests with the user. Rights in user content remain with the user; nothing in clause 5 below grants the operator any right in that content.

4. Licence to use

You are granted a limited, personal, non-exclusive, non-transferable and revocable licence to use the Site for personal, non-commercial learning purposes only. Any other use — including copying, reproduction, distribution, sale, rental, public display, creation of derivative works, data scraping, or commercial use of the Site's content — requires the operator's prior written permission.

5. Intellectual property

To the extent intellectual property rights subsist in the Site's content — including the design, the code, the selection of words and the way they are edited and arranged into levels, and the app's name and icons — they belong to the operator or to third parties who permitted their use, and are protected under copyright and intellectual property law in the European Union, Latin America, the United States, Israel and elsewhere.

For the avoidance of doubt: some of the translations were produced with the assistance of artificial intelligence tools, and under the law of certain countries output created in that way may not itself attract copyright protection. Nothing above asserts copyright in an individual word or translation as such, but rather in the compilation, editing, arrangement and presentation of the bank as a whole and in the Site's other components. The use restrictions in clause 4 apply in any event as a contractual condition of using the Site.

6. Prohibited uses

Using the Site in breach of any law or of these terms.
Attempting to disrupt the Site's operation, to circumvent technical limits, or to overload the hosting infrastructure.
Automated use (bots, crawlers and the like) to copy content, other than lawfully operating search engines.
Removing or obscuring copyright notices or credits.

7. Minimum age and minors

The Site is intended for users aged 14 and over. It is not intended for, directed at or marketed to children under 14, and must not be used by anyone under that age. A user who chooses "Agree and save" confirms that they are at least 14 years old. If the law of the user's country of residence sets a higher age for independent consent, that higher age applies. In Spain, Article 7 of Organic Law 3/2018 (LOPDGDD) sets the age for a child's own data-protection consent at 14.

The Site has no registration, accounts, advertising, analytics, cross-site tracking or profiling, and the app asks for no name, email address or other identifying detail. Technical server logs, and information sent voluntarily by email, are processed as described in the privacy policy. Because use of the Site requires a minimum age of 14 — above the threshold of 13 that the Act works from — the Site is not directed to children under 13 for the purposes of the United States Children's Online Privacy Protection Act (COPPA), and nothing is knowingly collected from them.

Use by minors aged 14 to 18 should take place with the knowledge of a parent or guardian. A parent or guardian who believes a child under 14 has used the Site may contact the address in clause 11. Scores, preferences, the words-to-improve list and user-added words can be deleted on the device using the app's deletion buttons or the browser's site-data controls; a request concerning server logs or an email can be sent to the same contact address.

8. Limitation of liability

To the maximum extent permitted by applicable law, the operator is not liable for indirect, consequential, special or punitive damage, or for loss of data caused by the browser, the user's device or circumstances outside the operator's reasonable control. Nothing in these terms excludes or limits liability that applicable law does not allow to be excluded or limited, including liability arising from fraud, intentional misconduct or gross negligence where the law so provides. See also the "Disclaimer" section below.

Force majeure: the operator will not be liable for delay, fault or interruption of service arising from circumstances outside its reasonable control — including a fault or outage at the hosting provider, a communications failure, a cyber attack, an infrastructure failure, a change in the browser or operating system on the user's device, or an order of a competent authority.

Responsibility for unlawful use: to the extent permitted by law, a user is responsible for a third-party claim caused directly by that user's intentional unlawful use of the Site or material intentional breach of these terms. This does not apply to ordinary use, to a claim caused by the operator, or where mandatory consumer law provides otherwise.

9. Changes to these terms

The operator may update the Legal Documents from time to time. The date of the last update appears at the top of each document. A material change will be highlighted on the Site in a reasonably prominent notice before it applies, where practicable, and will not retroactively expand the operator's rights over information already provided. If a change requires renewed consent to device storage, the Site will ask for it separately before that storage continues.

Reading these documents offline. An app added to a device keeps a copy of the Site's files so that it works without a network, and a copy read while offline may therefore be older than the current text. Pages are fetched fresh whenever a network is available, so that this cannot happen while the Site is reachable. The authoritative version of the Legal Documents is always the one published at droneparts.net, and the date at the top of each document is what identifies it.

10. Governing law and jurisdiction

These terms and the use of the Site are governed by the law of the State of Israel, where the operator resides, and jurisdiction in any matter concerning the Site is granted to the competent courts of the Tel Aviv-Jaffa district, Israel.

Reservation in favour of consumer users: nothing above derogates from mandatory protective consumer-law provisions that cannot be contracted out of and that apply to the user in their country of habitual residence, and nothing above deprives the user of the protection those provisions afford. In particular:

Spain and the European Union — a user acting as a consumer and residing in Spain or another EU Member State may bring proceedings in the courts of their own country of residence, and may only be sued there, in accordance with Articles 17–19 of Regulation (EU) 1215/2012 (Brussels I bis).
Latin America — a user acting as a consumer retains every right conferred on them by the mandatory consumer-protection law of their country of residence, which in most of the region applies territorially and cannot be displaced by a choice of foreign law: among others Mexico's Ley Federal de Protección al Consumidor, Argentina's Ley 24.240, Colombia's Ley 1480 de 2011 (Estatuto del Consumidor), Chile's Ley 19.496 and Peru's Ley 29571.
United States — a consumer residing in the United States retains any right conferred on them by the mandatory consumer law of their state of residence.

Where a provision of this clause conflicts with such a protective provision, the protective provision prevails, without affecting the validity of the remaining terms. If any provision of these terms is held invalid, the remaining provisions stay in force.

11. The operator and contact

Who runs the Site. These details are published here and kept permanently and directly accessible, as Article 13 GDPR requires them to be given:

Name: [operator's name]
Country: Israel
Email: contact@droneparts.net

Nature of the operator: the Site is run as a personal, non-commercial project by an individual resident in Israel, who does not act through a company or a registered business, charges nothing for use of the Site, displays no advertising on it and derives no income from it. There is accordingly no commercial register entry, no tax or registration number, and no professional body or authorisation scheme to declare.

This also settles which identification rules apply. The detailed disclosure that Article 10 of Spain's Law 34/2002 (LSSI) requires — a postal address, a registration number, and the rest — is owed by a provider of an information society service, and that concept reaches a service given away free only where it amounts to an economic activity for the provider: an advertising-funded site, for instance. This Site earns nothing, in any form, from anyone. What remains is Article 13 GDPR, which asks for the identity and contact details of the controller and is satisfied by the name and working email address above. No postal address is published, and none is required.

How to get in touch: email contact@droneparts.net. This is the Site's contact address for every matter — terms of use, privacy, accessibility and reports of errors in the content — and it reaches the operator directly.

Privacy policy

Last updated: 10 August 2026

1. The principle: your information stays with you

The Site was designed on a "privacy by default" basis (Privacy by Design & by Default). It has no registration, accounts, forms that submit information, analytics tools (such as Google Analytics), marketing pixels, advertising or cross-site tracking. The operator nevertheless processes a limited amount of personal information through the hosting provider's technical server logs and when a person voluntarily sends an email; those activities are described below. The "type the answer" quiz is checked on the device only and the answer is neither transmitted nor retained. Words and translations added on the "My words" page stay in the browser's local storage, after consent, and are not sent to the operator or a server.

2. Data stored on your device only (localStorage and sessionStorage)

Saving progress on your device happens only after express consent (opt-in) given in the consent banner shown on a first visit, and it can be withdrawn at any time on the settings page. Without consent, progress is held in the page's memory only and is erased when the page closes. After consent, the following data is stored solely in your browser's local storage, on your device, and is not sent to the operator:

droneparts.net.words-quiz.word-stats.v1 — practice statistics per word (correct and wrong answers), the words you marked as favourites, and the words-to-improve list together with the count of consecutive correct answers on each word still on it. All three kinds of data live under the same key, but each has its own deletion button and each is deleted on its own: clearing the statistics resets the counters only and leaves the favourite marks and the list intact.
droneparts.net.words-quiz.games.v1 — up to the last 500 rounds (time, score and duration).
droneparts.net.words-quiz.settings.v1 — personal preferences (words per round, how the next word arrives — a waiting time or advancing on click, the answer time limit (off by default), the practice direction, the quiz type, the preferred voices, the speed the words are read out at, and whether collecting words to improve is switched on — off by default).
droneparts.net.words-quiz.custom-words.v1 — words you added yourself on the "My words" page (the word, its translation and the level you chose), up to 300 words. The text you type is stored on your device only, and is checked and displayed there only, and is not sent to the operator or to any third party. You can edit and delete any word on that page at any time, and delete them all together with the "Delete all my words" button; deleting a word also deletes the statistics gathered on it. That page also has a "Download my words as a text file" button, which lets you keep a copy of the words on your device — the file is built entirely in your browser and saved straight to your device, with no information sent or transferred to any server. Once saved, the file is your responsibility and is no longer subject to this policy.
droneparts.net.words-quiz.install.v1 — everything to do with the suggestion to add the app to your device: how many rounds you have finished, so that the suggestion first appears after five; when it was last shown, so that it appears at most once a week; whether the app has been marked as already added; and whether you pressed "Don't remind me again". It contains no identifier, nothing about which words you practised and nothing about the device. This record serves the Site's own suggestion rather than something you asked for, so it earns no exemption from consent and is given none: it is stored only after consent, like everything else in this list. Without consent the count is held in the page's memory and disappears when the page closes, so the suggestion cannot follow you between visits. Because it is stored under consent, it is deleted along with everything else when you delete all app data, and the suggestion may therefore appear again afterwards; switching it off again takes one press.
droneparts.net.words-quiz.consent.v1 — the choice (agree or refuse), the date of that choice and the applicable policy version. It is valid for no more than 24 months; on the first visit after expiry the record is removed and the Site asks again. A refusal is stored as a strictly necessary preference so that the Site respects it instead of repeatedly asking. This is the only record written whatever you chose, and it exists solely so that an answer you already gave is respected.
droneparts.net.words-quiz.editor-draft.es.v1 — a temporary draft from the words editor, held in sessionStorage and only after consent to save. The draft is deleted when consent is withdrawn or when the tab's session ends.

Every key this version creates uses a prefix unique to the app. The app never issues a blanket clear of browser storage, and withdrawing consent removes only its own dedicated keys — not data belonging to other sites or apps. To protect other apps on the same domain, this version neither reads nor deletes generic keys without that prefix, including any keys earlier versions may have created. Withdrawal is also synchronised with open tabs of the app so that data is not written back after deletion. If a consent record expires or becomes invalid, previously saved app data is not read or changed; it stays dormant until the user agrees again or chooses not to save, in which case it is deleted.

This data contains no identifying details, and it is under your control. The app offers six separate deletion actions, each with a defined scope shown to you in a confirmation dialog before it runs:

"Delete the statistics only" (statistics page) — deletes the round history (games.v1) and the correct/wrong answer counters inside word-stats.v1. Favourite marks, the words-to-improve list, the words you added, your preferences, the record of the install suggestion and your consent to save are unchanged.
"Remove all favourites" (favourites page) — removes the favourite marks inside word-stats.v1. The correct/wrong counters on those words, the words-to-improve list, the words you added, your preferences, the record of the install suggestion and your consent to save are unchanged.
"Clear the words-to-improve list" ("Words to improve" page) — empties the list inside word-stats.v1 and resets the consecutive-correct counters that belong to it. The statistics on those words, your favourites, the words you added, your preferences, the record of the install suggestion and your consent to save are unchanged. Collecting stays switched on, so a word you get wrong again will rejoin the list; switching the collecting itself off is a separate control on the settings page.
"Delete all my words" ("My words" page) — deletes the words you added (custom-words.v1) and only the statistics, favourite marks and words-to-improve entries gathered on them. All other data and your consent to save are unchanged.
"Reset settings to defaults" (settings page) — returns the preferences in settings.v1 (words per round, waiting time, answer time limit, speech speed, voices, practice direction, quiz type, and collecting words to improve — which returns to off) to their default values. No other data is deleted, the words-to-improve list itself is not emptied, the record of the install suggestion is not affected, and consent to save is not withdrawn.
"Delete all app data and withdraw consent" (statistics page, and the settings page under the name "Withdraw consent and delete the stored data") — deletes every key listed above, including install.v1 and the editor draft, and records the withdrawal of consent. One thing deliberately survives it: the consent record itself, which now reads as a refusal, because erasing it would simply mean being asked again. The offline copy of the Site's own files described below is not personal data and is not part of this deletion either; it is removed by uninstalling the app or by clearing this site's data in the browser.

2a. Installing the app on your device, and its offline copy

The Site can be added to a device's home screen and opened in its own window. Doing so is a function of your browser, not a download from an app store: no account is created, no separate program is installed, and the app handles information exactly as the version in a browser tab does — nothing is sent to the operator either way. The manifest that describes the app to the browser attaches no parameter to the address the app opens at, so a visit launched from a home screen is indistinguishable from any other and the operator cannot tell them apart or count them.

The offline copy (Cache Storage and a service worker). So that the app opens without a network — which is what an installed app is expected to do — the browser keeps a copy of the Site's own files: the pages, the stylesheets, the scripts, the word list, the manifest and the icons. That is the whole of it. It contains none of your data — no progress, no statistics, no favourites, no words-to-improve list, no words you added, no preferences and no identifier of any kind — and nothing in it is sent anywhere. Its content is the same for every visitor, and it is the same material the browser's ordinary cache already holds. It is used on this basis rather than on consent, as a technical means strictly necessary for delivering the service you asked for, and it is disclosed here for transparency. You can remove it at any time by uninstalling the app or by clearing this site's data in your browser settings, and the app keeps working without it.

A separate storage area on iPhone and iPad. On iOS and iPadOS, a page added to the Home Screen is given a storage area of its own, separate from the browser's. Your statistics, favourites, words-to-improve list, the words you added and your choice about saving on the device do not carry over from the browser to the app, and the app will ask about saving again the first time you open it. Nothing is deleted by this — the data in the browser stays where it is — but the two do not share it, and a word added in one does not appear in the other. On Android and on desktop the app and the browser share one storage area, so a single choice and a single set of data serve both.

Removing the app. Uninstalling the app, or removing it from the Home Screen, may delete everything it stored on the device — on iOS that separate area generally goes with it. That deletion is performed by the operating system and cannot be undone; keeping a copy of any words you added, using the button on the "My words" page, is recommended before removing the app.

The first five deletion actions are confined to the kind of data they name, and resetting the settings deletes no data at all. The sixth action applies to all the keys listed above; since every page of the Site on the same domain shares those storage keys, it also removes data saved from other pages of the Site in the same browser. Clearing the site's data in browser settings will likewise remove all of the Site's data. In private browsing mode the browser may allow temporary storage during the session but usually deletes it when private browsing ends; the Site keeps working even when storage is blocked.

3. Third-party services

Fonts: the Site does not download or distribute font files and does not call any external font service. Text is displayed using the default fonts already available in your browser and operating system.
Speech (Web Speech API): words are spoken using the speech engine built into your browser or operating system. In some browsers the spoken text, your IP address and technical data about the browser or device may be sent for processing to the browser vendor's servers (Google's network voices, for example). That processing is governed by the privacy policy of the browser or operating-system vendor you chose. This applies to words you added yourself as well, if you press the speak button on one of them.
Adding the app to a device: installing is carried out by your browser and your operating system, and the operator takes no part in it and is told nothing about it. Be aware that the browser may involve its own vendor: on Android, Chrome and browsers built on it send the app's manifest and the addresses of its icons to Google's servers in order to build the home-screen app, and other browsers may behave comparably. On iOS and iPadOS, adding to the Home Screen is handled on the device by Apple's software. What is sent in that process is the Site's public files and the ordinary technical data of a request; none of your progress, statistics, favourites or added words is involved, because none of it leaves the device at any point. That processing is governed by the privacy policy of the browser or operating-system vendor you chose, exactly as with the speech engine above, and adding the app is never required in order to use the Site.
The hosting provider: the Site is hosted by A2 Hosting, LLC, trading as hosting.com. The server records standard technical log data, including IP address, browser and operating-system type, requested page, referrer where supplied and request time. An IP address may be personal data. Purpose and legal basis: security, abuse and fault detection, and reliable delivery of the Site, based on the operator's legitimate interests under Article 6(1)(f) GDPR. The logs are not used by the operator for marketing or profiling. Retention: routine logs are rotated and deleted in accordance with the provider's documented log-retention cycle, which is the criterion used for their retention. The operator does not ordinarily download them. A copy made to investigate a specific incident is deleted when the investigation and any related legal requirement end. See hosting.com's privacy information.
Email enquiries: if you write to contact@droneparts.net, the operator receives your email address, any name or signature you provide, message content and ordinary email metadata. They are used only to answer the enquiry, handle a rights or accessibility request, correct reported content, meet a legal obligation or establish and defend legal claims. The basis is legitimate interests in answering and administering enquiries (Article 6(1)(f) GDPR), compliance with a legal obligation where applicable (Article 6(1)(c)), or steps requested by you where Article 6(1)(b) applies. Ordinary correspondence is deleted within 24 months after the matter closes; information reasonably required for an unresolved legal obligation or claim is kept only for the applicable period. The domain's email service and its infrastructure providers process the message in order to deliver and store it.
Recipients and transfers outside the EEA: hosting.com and the domain's email infrastructure act as Processors to the extent they handle information on the operator's instructions, and may act under their own legal responsibilities for security and legal compliance. Their infrastructure may process information in the United States. Where it does, the transfer relies on the safeguards in the data-processing terms agreed with that provider under Chapter V GDPR — the standard contractual clauses approved by the European Commission, or the provider's certification under the EU–U.S. Data Privacy Framework where that certification covers the transfer. You may ask which of the two applies, and to see the relevant terms, at the address in clause 7. Information accessed by the operator in Israel is covered by the European Commission's adequacy decision for Israel. A browser or operating-system speech provider may separately receive spoken text and technical data when the user activates speech, as explained above. The operator does not sell or rent personal information and does not disclose it for behavioural advertising.

4. Compliance — GDPR, Spain, Latin America and the United States

This policy applies the principles of the European General Data Protection Regulation (GDPR), Spain's Organic Law 3/2018 (LOPDGDD) and Israel's Protection of Privacy Law, 5741-1981 and its regulations. Personal information processed on the operator's behalf is limited to the technical server logs and voluntary email correspondence described in clause 3. Processing by a speech engine built into the browser or operating system occurs through a component selected by the user and is governed by that vendor's privacy terms; the operator does not receive the spoken text or the resulting technical data.

Legal basis (GDPR). Server logs and ordinary correspondence rely on the legitimate interests described in clause 3; a legal request may also require processing under Article 6(1)(c). Device storage relies on consent under Article 6(1)(a), requested separately from the terms and withdrawable at any time. Where the basis is legitimate interests, the operator's assessment is that they are not overridden by your interests or rights: the information involved is the minimum a web server records in order to serve a page and stay secure, it is not combined with anything else, it is not used to build a profile or to market anything, and it is neither sold nor shared. You may object to that processing at any time under Article 21 GDPR, at the address in clause 7.

Your rights (GDPR). If you are in the European Union you have the rights of access, rectification, erasure, restriction, portability and objection. The data stored in your browser can be managed and deleted directly on your device, and for any request concerning the server logs, or any other question, you can contact us at the address in clause 7.

Latin America. Users in Spanish-speaking countries of Latin America are covered by their own national data-protection law, among them Mexico's Ley Federal de Protección de Datos Personales en Posesión de los Particulares, Argentina's Ley 25.326, Colombia's Ley 1581 de 2012, Peru's Ley 29733 and Chile's Ley 19.628 (with the new framework under Ley 21.719 as it comes into force). Those laws grant rights broadly equivalent to access, rectification, cancellation or erasure, and objection — known in much of the region as derechos ARCO. The operator applies the standard described in this policy to every user regardless of country, and a request under any of those laws can be sent to the contact address in clause 7 and will be handled in the same way as a GDPR request. Note again that the practice data itself never reaches the operator: it can be inspected and deleted by the user directly, on their own device, at any moment and without asking anyone.

United States. The operator is an individual running a personal, non-commercial project and does not meet the ordinary for-profit business thresholds of the California Consumer Privacy Act as amended by the CPRA. Regardless, the operator does not sell or share personal information for cross-context behavioural advertising. California residents and residents of states with comparable laws may contact the address in clause 7 with a request. The Site is intended for users aged 14 and over, and because that minimum sits above the threshold of 13 used by the Children's Online Privacy Protection Act, the Site is not directed to children under 13 for COPPA purposes and the operator does not knowingly collect personal information from them.

Right to lodge a complaint with a supervisory authority: if you believe the processing described in this policy is unlawful, you have the right to lodge a complaint with a supervisory authority, in addition to any other remedy and without being required to contact us first:

In Spain — the Spanish Data Protection Agency, Agencia Española de Protección de Datos (www.aepd.es).
Elsewhere in the European Union — the supervisory authority in your country of residence, your place of work or the place of the alleged infringement, under Article 77 GDPR. A list of authorities is published on the European Data Protection Board's website.
In Latin America — the national data-protection authority of your country, such as Mexico's authority for access to information and data protection, Argentina's Agencia de Acceso a la Información Pública, Colombia's Superintendencia de Industria y Comercio, Peru's Autoridad Nacional de Protección de Datos Personales, or Chile's competent authority.
In Israel — the Privacy Protection Authority at the Ministry of Justice (www.gov.il/en/departments/the_privacy_protection_authority).

We would be glad if you contacted us first at the address in clause 7 — we will do our best to look into it and put it right — but that is not a precondition for complaining.

5. Information security

The Site is intended to be served exclusively over HTTPS. Server rules redirect an HTTP request to HTTPS and instruct supporting browsers to use HTTPS for future visits. Keeping the browser and operating system up to date is recommended.

In addition, a restrictive Content Security Policy is applied twice over: the server sends it as a response header on every request, and each page carries its own copy, usually tighter still — this page of legal documents, for instance, permits no scripts at all, and a browser enforces whichever of the two is stricter. Between them they block framing, confine scripts, styles, images and connections to the Site itself, forbid form submission, and switch off browser permissions the Site has no use for, among them camera, microphone and location. The manifest and the service worker that make the app installable are restricted to the Site by that same policy and cannot be loaded from anywhere else. On the app page, a same-origin request re-reads the Site's word bank to check its version and sends no saved app data. The service worker handles requests to this site only, passes anything else through untouched, and stores nothing but the Site's own files. The policy does not govern internal traffic of browser or operating-system services such as the speech engine, which may process information as described in clause 3.

6. Minimum age, minors — and privacy in plain language

The Site is intended for ages 14 and over and is not intended for, directed at or marketed to children under 14. The app does not ask for a name, contact detail or age and has no account or user-submission server. Technical server logs are created for all visits, and an email is processed if someone voluntarily writes to the operator, as described in clause 3. Parents and guardians are welcome to read this policy and contact the operator with a question.

If a child under 14 has used the Site, local scores, preferences, the words-to-improve list and user-added words can be removed immediately using the app's deletion buttons or the browser's site-data controls. A parent or guardian may contact the operator about a server-log entry or an email, although limited log data may not make it possible to identify a particular child without additional information.

For younger users, in plain words: the Site does not ask you for your name, your address or any other detail. Your score and your progress are saved only on your own computer or phone — they are not sent to us. If something is not clear, ask a parent or another adult for help.

7. The data controller and privacy enquiries

Who the controller is: the operator — an individual resident in Israel who runs droneparts.net as a personal, non-commercial project, with no company and no registered business — is the "Controller" for the server logs and correspondence described in this policy. The controller's name and contact details are published in clause 11 of the terms of use on this page, as Article 13(1)(a) GDPR requires them to be given, and are not withheld pending a request. That Article asks for identity and contact details; it does not require a postal address, and none is published, for the reasons given in that clause. No data protection officer (DPO) has been appointed because the limited processing does not involve large-scale monitoring or large-scale processing of special-category data.

EU representative: no representative has been appointed under Article 27 GDPR. Requests from people in the European Union can be sent directly to the contact address below. If a representative is designated, its identity and contact details will be published here.

Contacting us: for any question or request concerning privacy — including exercising the rights set out in clause 4 — you can write to contact@droneparts.net. We will try to reply as soon as possible, and in any event within the period required by any law applicable to your request (one month under Article 12(3) GDPR, extendable as that Article permits). There is no charge for contacting us. If you are not satisfied with the response, you have the right to lodge a complaint with a supervisory authority as set out in clause 4.

Cookie policy

Last updated: 10 August 2026

1. The Site does not use cookies

The Site's code does not create, read or store cookies — no functional cookies, no analytics cookies, no advertising cookies and no third-party cookies. Accordingly there is no "cookie banner" on the Site.

This statement concerns the Site's own code, which is what the operator controls. If the hosting provider or an intermediate infrastructure sets a technical cookie of its own at the server level, that is outside the operator's control and is not done on its behalf; should the operator learn of such a cookie, this policy will be updated accordingly.

2. A similar technology: local storage (localStorage and sessionStorage)

For full transparency: the Site uses localStorage to save progress, preferences, the words-to-improve list, words the user added and the timing of the suggestion to add the app to the device, and sessionStorage for temporary drafts in the words editor. These mechanisms are technically similar to a cookie, but the data in them is never sent to any server with network requests. Their use is strictly functional, as described in the privacy policy, and involves no tracking, identification or advertising.

The choice is yours — prior consent (opt-in): the Site stores no progress, favourites, words-to-improve list, preferences, words you added, timing of the app-install suggestion or editor drafts without express consent. One record is written regardless, and it is the only one: your storage choice itself. It exists solely so the Site respects an answer you already gave instead of asking again, which is what makes it strictly necessary, and it is described in clause 2 of the privacy policy. The request concerns device storage only and is separate from the terms of use and privacy notice. "Agree and save" and "Don't save" are presented together with equal-sized controls. Refusing does not restrict the learning content or quizzes. The strictly necessary record at droneparts.net.words-quiz.consent.v1 contains the choice, date and policy version so the Site can respect it; the choice is requested again no later than 24 months after it was recorded. If an earlier grant expires, saved app data remains inactive and unread until the user chooses again. Consent can be withdrawn in Settings, which deletes the app's saved data. This approach follows Article 5(3) of the ePrivacy Directive as implemented in Spain in Article 22.2 of Law 34/2002 (LSSI).

3. The offline copy of the Site (a service worker and Cache Storage)

The Site can be added to a device's home screen and opened in its own window. So that it opens without a network — which is what an installed app is expected to do — and so that a returning visitor gets the screen quickly, the browser keeps a copy of the Site's own files: the pages, the stylesheets, the scripts, the word list, the manifest and the icons.

What that copy is not. It holds nothing about you: no progress, no statistics, no favourites, no words-to-improve list, no words you added, no preferences, no identifier and no record of what you did on the Site. Its content is identical for every visitor, it is never sent anywhere, and it cannot be used to recognise a device or a person. It is the same material the browser's ordinary cache already stores; the difference is only that the app can read it when there is no network.

Why it is not behind the consent request. Storing the files needed to display a page that was asked for is a technical means strictly necessary to provide the service the user requested, within the exemption in Article 5(3) of the ePrivacy Directive as implemented in Spain in Article 22.2 of Law 34/2002 (LSSI). Everything that is about you — including the timing of the app-install suggestion — sits on the other side of that line and is stored only after consent, as set out in clause 2. The offline copy is disclosed here so the position is transparent rather than assumed.

Removing it. Clearing this site's data in your browser settings removes it, and so does uninstalling the app. The Site works normally without it. Because it is a copy, a page read offline may be older than the one on the Site: pages are fetched fresh whenever there is a network, precisely so that these legal documents are never served out of date while the current text is a request away.

4. Third parties

The Site uses only the default fonts of the browser and operating system, and loads no font files from the Site or from third-party servers. There are no embedded components (videos, maps, social network buttons) and no third-party services that could set cookies. The hosting provider (hosting.com) serves the Site's files only and does not set cookies through the Site; the technical server logs it keeps are described in the privacy policy. Adding the app to a device may involve the browser's own vendor — on Android, Chrome sends the manifest and icon addresses to Google in order to build the home-screen app — as described in clause 3 of the privacy policy; no cookie is set through the Site in that process and none of your data is involved in it.

5. Managing and deleting

You can delete the Site's local storage data at any time through your browser settings (Clear browsing data) or using the deletion buttons in the app. There are six buttons of differing scope: "Delete the statistics only" and "Delete all app data and withdraw consent" on the statistics page, "Remove all favourites" on the favourites page, "Clear the words-to-improve list" on the "Words to improve" page, "Delete all my words" on the "My words" page, and "Reset settings to defaults" on the settings page. Each is preceded by a confirmation dialog spelling out exactly what is deleted and what remains. Only "Delete all app data and withdraw consent" (and the identical "Withdraw consent and delete the stored data" on the settings page) withdraws consent to save; the other five are targeted and do not touch consent. Full details are in the privacy policy, clause 2. The buttons remove only the keys this version creates under the app's unique prefix and do not trigger a blanket deletion. They do not remove the offline copy described in clause 3, which holds none of your data; that goes when you clear the site's data in the browser or uninstall the app. Blocking local storage in the browser will not prevent use of the Site — but progress will not be kept between visits.

The suggestion to add the app to your device can be stopped without deleting anything: "Don't remind me again" on the install card in the settings ends it, and "Show the suggestion again from time to time" on the same card brings it back. That choice lives in install.v1 and is therefore stored under consent, which means "Delete all app data and withdraw consent" clears it along with everything else and the suggestion may appear again afterwards. The suggestion appears at most once a week, only after a round has finished, only on the home and results screens, and never once the app has been added.

To be precise about what that limit covers: it describes the suggestion that appears by itself, and only that. Adding the app on your own initiative is available at any time through a permanent card on the settings page, which is not rationed and stays reachable even after the suggestion has been switched off. That card is hidden only in a browser that offers no way to install at all. Neither the card nor the suggestion records anything about you beyond what clause 2 of the privacy policy already lists, and the timing record is written only when the suggestion appears by itself.

6. Future changes

If cookies or tracking technologies are added to the Site in future, this policy will be updated in advance, and where the law requires it a suitable consent request will be presented before they are activated.

Disclaimer

Last updated: 10 August 2026

1. Educational content only

The content on the Site is for learning only. Translations may be inaccurate, and no liability is accepted for loss arising from reliance on them.

The Site and all its content — including the word bank, the translations, the spoken pronunciation and the statistics — are intended for general learning and enrichment only. They do not constitute professional advice of any kind (linguistic, educational, business, legal or other) and must not be relied on as such.

2. Accuracy of the content

The word bank and the translations were prepared with reasonable care, but translation is always context-dependent: many words have several meanings, and the translation shown reflects only one common sense. Regional variation matters too — Spanish differs between Spain, Mexico, the River Plate and the rest of Latin America, and English between the United Kingdom and the United States — and the form chosen is not necessarily the one used in your region. Where a translation has two common equivalents, both are given, separated by a slash, and either is accepted when the answer is typed. The operator does not warrant that the content is free of errors, accurate, complete or up to date, and accepts no liability for any use made of it, including in examinations, at work or in any other context. Found a mistake? We would be glad to hear about it by email: contact@droneparts.net.

3. Service as is

The service is provided "AS IS" and "AS AVAILABLE", without warranty of any kind, express or implied, including any implied warranty of merchantability, fitness for a particular purpose or non-infringement. The operator does not warrant that the Site will operate without interruption or fault, in every browser or on every device. Nor does it warrant that the Site or its files are free of errors or harmful components, and it accepts no liability for damage caused to the user's device, its software or its data as a result of using the Site.

4. Local data

A user's progress — the statistics, the favourites, the words-to-improve list and the words they added themselves — is stored in the browser only. Clearing browser data, changing device, private browsing mode, a browser fault, and equally a fault, error, update or change in the Site itself, may cause the loss of that data; this list is not exhaustive. Browser storage is limited in size, and when it fills up saving may fail and progress may be kept for the browsing session only; the Site shows a message when that happens. The operator is not responsible for such loss and cannot restore that data — it was never in the operator's possession and is backed up on no server.

Updating the word bank: statistics, favourite marks and the words-to-improve list are stored per word identifier. A word removed from the bank, or whose identifier changes in a Site update, therefore causes what was gathered on it to be deleted from the device on the next load — without notice and with no way to restore it. See clause 2 of the terms of use. The words you added yourself are not affected.

Adding the app to a device, and removing it. An app added to a home screen stores its data on that device just as the browser version does, and the same limits apply to it. Two things are worth knowing before it happens. On iPhone and iPad the app gets a storage area of its own, separate from the browser's: statistics, favourites, the words-to-improve list, words you added and the choice about saving do not carry over, the app starts empty and asks about saving again, and a word added in one of the two does not appear in the other. Nothing is deleted by this, but nothing is shared either. Removing the app may delete everything it stored — on iOS that separate area generally goes with it. That deletion is performed by the operating system, is outside the operator's control, cannot be undone and cannot be restored by the operator, which never held the data. Downloading a copy of any words that matter to you before removing the app is recommended.

Reading the Site offline: an added app keeps a copy of the Site's files so that it works without a network, and what is shown offline may therefore be an older version — including of the legal documents. Pages are fetched fresh whenever a network is available. The authoritative version is always the one published at droneparts.net.

Scope of the backup: the "My words" page has a button to download the words you added as a text file to your device. That button exports the words you added only: the statistics, the round history, the favourite marks and the words-to-improve list cannot be exported and have no restore path of any kind — once deleted, they are gone. Keeping an offline copy of words that matter to you is recommended.

5. Browser-dependent features

The spoken pronunciation is an illustrative aid and is not an authoritative pronunciation guide. The sound itself is neither recorded nor produced by the operator; it is generated in real time by the speech engine built into your browser or device. Such engines may err in pronunciation, stress or intonation, may read a word according to the language configured for them rather than the context, and may sound different across browsers, voices and devices. Regional accent is a particular limitation: a Spanish voice may be Peninsular or Latin American, and an English voice British or American, without that being under the Site's control. The app asks for a Spanish voice first and falls back to a Latin American one where no Peninsular voice is installed, which means the accent you hear depends on what your device happens to provide. Verifying pronunciation against an additional linguistic source is therefore recommended. Availability of speech depends on your device's capabilities.

Adding the app to a device is likewise a feature of the browser and not of the Site. Whether it is offered, what it is called, whether the app then works offline and what happens to its data when it is removed are decided by the browser and the operating system, differ between them and may change with their updates. The operator does not warrant that the option will be available on any given device or browser, and the Site is fully usable in an ordinary browser tab without it.

6. External links and services

To the extent the Site refers to external services, the operator is not responsible for their content, their availability or their policies.

7. Overall limitation of liability

The operator's liability in connection with the Site is limited to the maximum extent permitted by law, bearing in mind that this is a free service provided without consideration. Nothing in this section derogates from rights that cannot be contracted out of under applicable law, or from liability that cannot be limited or excluded under applicable law.

Accessibility statement

Last updated: 10 August 2026

The Site was built with the intention that it be usable by everyone, including people with disabilities. The target set for it is WCAG 2.1 Level AA, the standard referenced by EN 301 549 in the European Union and the most widely used international benchmark for web accessibility.

This target is one the operator has set voluntarily, and it is worth being clear why. The European rules that make accessibility compulsory for a website — Directive (EU) 2016/2102, and in Spain Royal Decree 1112/2018 — bind public sector bodies, which the operator is not. The European Accessibility Act, Directive (EU) 2019/882 and Spain's Ley 11/2023, reaches services offered as an economic activity, and exempts the smallest providers from its service obligations in any event. As clause 11 of the terms of use explains, this Site charges nothing, carries no advertising and earns nothing in any form. No accessibility statute is therefore owed here. What follows is a description of how the Site was built, offered because it is useful to know — not a warranty, and not a claim of certified conformance.

How the Site was built. It can be operated from the keyboard alone, with a visible focus indicator and a skip link to the content. Its structure is semantic, with ARIA labelling and polite announcements for screen readers, and each practice word carries a language marking so that a screen reader pronounces it in the right language. Text colours are chosen to meet the AA contrast threshold, and no feedback depends on colour alone — a correct or wrong answer is always stated in words as well. The preference for reduced motion is honoured. No sound plays by itself; every readout follows a deliberate press. Timing is under the reader's control: the automatic move to the next question can be slowed or switched off altogether, and the optional answer time limit is off unless it is switched on. The layout is responsive and holds together when the page is enlarged. Dialogs close with the Escape key, and the suggestion to install the app neither covers the page nor captures the keyboard, and can be postponed or switched off for good.

What has not been assessed. The checks carried out were automated ones, run against the pages and the main screens of the app, together with a reading of the code. Automated tools reach only part of what the standard requires — by common estimate a minority of it — and no amount of them substitutes for testing with real assistive technology and real users. No professional external accessibility audit has been carried out, and the Site has not been tested with screen readers by people who depend on them. The Site is also updated from time to time, and a description written today can fall behind the code. This is therefore a statement of intent and not a statement of conformance: gaps that have not been identified may exist, and the paragraph above should be read as what was aimed at rather than as a guarantee of the result. A known limitation: spoken pronunciation depends on the voices installed on the device, and will not work where none are present.

The record of what was checked. The checks behind this statement — what was tested, with which tool, and what came back — are written up in a separate technical record that is kept outside these documents so that it can be corrected without reopening them. A copy is available from the contact address below to anyone who asks.

Run into a difficulty? We would like to know and to fix it — contact@droneparts.net. Please describe the nature of the problem, the browser and the assistive technology you are using.
