Terms of Service

1. Independence and non-affiliation

“EnglishPrepository” is an independent educational tool. It is not supported by, endorsed by, sponsored by, licensed by, or in any way associated or affiliated with ANY examination, examination board, test provider or certification body — including, but not limited to, Cambridge University Press & Assessment, the University of Cambridge, ETS, the British Council, IDP, Pearson, Trinity College London, and the Council of Europe. No examination or test has endorsed this service and this service does not represent any of them. It prepares learners for English at the levels labelled on each exercise in general and does not guarantee admission to, or any result in, any official examination.

2. Trademarks and levels

All examination and test names, and all related marks and logos, are the trademarks of their respective owners and are unrelated to this service. Where such a name appears here at all, it is used only to describe the kind of English practice a learner may want, never to suggest any connection, approval or equivalence. The Common European Framework of Reference for Languages (CEFR) and its level scale A1–C2 belong to the Council of Europe, which has no connection with this service. The level shown on an exercise (for example “B2”) is this service's own estimate of its difficulty on that scale; it is not a certification, a score, or a statement by any examination body about you or about the exercise.

3. Purpose

The application and books provide practice exercises for learners of English graded by CEFR level, from beginner (A1) to proficiency (C2), as labelled on each exercise. Exercises are written and checked entirely by artificial-intelligence models (section 10) and are provided for study purposes only.

4. No accounts

There is no sign-up and there are no user accounts. Every exercise is open to anyone: you answer it, you are shown the marked answers with explanations, and that is the end of it. Your answers and score are not saved, so there is no account to sign in to or to delete. The single administrator account exists only to create and edit exercises.

5. Content and accuracy

Exercise content is written by artificial-intelligence models and checked by several artificial-intelligence models before it is published; the administrator can correct any exercise. Despite this multi-model validation, errors may occur; no warranty of accuracy is given. If you believe an exercise contains an error, write to info@endlessmedical.com.

6. Copyright

This compilation is provided for personal study. Exercise content is machine-generated. You may not resell the individual exercises as your own original work.

7. Sharing

The share buttons link to the exercise itself, never to your answers or your score — those are never saved anywhere and cannot be linked to. A shared exercise page is public to anyone with the link, which is the point of sharing it.

8. Privacy

No accounts, no sign-up, no cookies, no tracking, no analytics service, no advertising, and no third-party scripts of any kind. Your answers are marked while the page loads and the site never writes them down: it keeps no score and no history. Your progress — which exercises you have finished and your last score in each — is kept only in your own browser, on your own device (its local storage, not a cookie), so the dashboard can show it to you; it is never sent to the site, and "Clear my progress" on the dashboard, or clearing your browser's data, removes it. The application itself sets no cookie on any public page and keeps no per-visitor log. It counts two things, neither of them about who opened anything: how many public pages are opened in each hour — a single number per hour — and how many times each page is opened per day (a free worksheet: downloaded) — a single number per page per day. The total for the last 30 days is shown on the home page. The pages are delivered through Cloudflare, a network service that, like every such service, handles the internet address of each request to deliver the page and to protect the site from attacks, under its own privacy policy. The site's own web server keeps no log of visits (since 20 October 2026). Its protection against attacks may note the internet address a request came from, for a limited time and only for that purpose, and an address that attacked the site may be kept on a block list. None of this is used for anything else, combined with any other data, or sold or shared. To ask what is held about you, or to have it erased, write to info@endlessmedical.com; you may also complain to the data protection authority where you live. The operator also keeps a record of every attempt to sign in to the administrator's account — the time, the internet address and the browser's name — which exists to detect break-in attempts against that one account.

9. No warranty / liability

Exercise content is generated and checked entirely by artificial-intelligence models, with no person writing or reviewing each exercise, and is provided for study purposes only. Despite a multi-model validation process, errors may occur; no warranty of accuracy is given. The service and this book are provided "as is", without warranty of any kind. To the maximum extent permitted by law, the operators are not liable for any damages arising from the use of the service or this book.

10. Made by artificial intelligence: texts, pictures, voices and videos

Everything in the exercises is made entirely by artificial intelligence: the texts, questions, answers, explanations and hints are written by artificial-intelligence models and checked by other artificial-intelligence models, with no person writing or reviewing each exercise before it is published (section 5). Every picture on this site and in its books is made by an artificial-intelligence image model; it illustrates the exercise and is not a photograph of a real scene, place or person. The voices in the listening exercises, the promo videos and the quiz videos (on this site and on YouTube) are synthetic voices made by artificial intelligence, and the speakers are fictional. Every page says so once, at the top; each video says so in the video and in its description; and the books say the same inside. Because the content is made by AI and has not been reviewed by a person, it can contain mistakes: do not rely on it without checking (section 9).
