The agreement
The rules, in language you can actually read.
What you can expect from the service, and what it expects from you — without the wall of capitals.
Terms nobody reads protect nobody. These are meant to be read once and understood.
Versão curta
- Your books stay yours; we store them only to sync your library.
- No lock-in — delete your account whenever you like.
- Usage limits exist because calls cost money, not to upsell you.
- We will tell you before anything here changes materially.

1.The service
The reader lets you import EPUB files you already have, read them, tap words for an explanation generated by an AI model, and review those words over time. It is provided by [ADD LEGAL ENTITY].
2.Your account
You need an account to save anything. Keep your password to yourself; you are responsible for what happens under your account. One person per account. You must be at least 13 years old.
3.Your books
You keep every right you already had in the files you upload. We store them only to give them back to you on your other devices, and we do not read, share or publish them.
You must have the right to the files you upload. Do not upload books you have not bought or that are not otherwise lawfully yours. We will remove material on a credible rights complaint and may close accounts that repeatedly infringe.
4.What the AI produces
Explanations are generated by a language model. They are usually good and they are sometimes wrong — that is the nature of the technology. Treat them as a well-read study partner rather than an authority, and do not rely on them where being mistaken would matter.
5.Fair use of the service
Accounts have limits on how many explanations, pronunciations and books they can use, because each one costs real money to serve. The current limits are shown in the app. Do not attempt to bypass them, scrape the service, or use it to build a competing dataset.
6.Availability
We aim to keep the service running and your data safe, but it is provided as-is, without a guarantee of uninterrupted availability. Keep your own copies of any book files that matter to you.
7.Ending it
You can delete your account at any time, which permanently removes your books, vocabulary and review history. We may suspend an account that breaks these terms, and will explain why unless we are prevented from doing so.
8.Liability
To the extent the law allows, we are not liable for indirect or consequential loss arising from your use of the service. Nothing here limits liability that cannot legally be limited.
9.Changes
We may update these terms. If a change materially affects you, we will tell you before it takes effect.
10.Governing law
These terms are governed by the laws of [ADD JURISDICTION].
