Close Reader

Terms of Use

Last updated: 11 October 2026

These Terms govern your use of the Close Reader app and this website (the “Service”), provided by Ilia Ilinskii PR Novi Sad, Mite Ruzica 3, Novi Sad, Serbia (“we”, “us”). By using the Service you agree to these Terms. If you don’t agree, please don’t use it.

1. The Service

Close Reader is an e-book reader with AI features: word translations and meanings in context, reminders about characters and places, explanations of passages, and a chat about the book. We may change, add or remove features over time, and features may occasionally be limited or temporarily unavailable.

2. Who can use it

You must be at least 13 years old. If you are under the age of majority where you live, a parent or guardian must agree to these Terms on your behalf.

3. Your account

You can use Close Reader without an account. If you create one, keep access to your email or sign-in method secure: you are responsible for what happens in your account. You can delete your account at any time in the app (Settings → Account → Delete account).

4. Your books and content

Close Reader doesn’t sell or provide books, except a few public-domain samples. You may import only files you have the right to use, and you must not use the Service to break copy protection (DRM) or infringe anyone’s rights.

Your own catalogs. You can connect Close Reader to OPDS catalogs whose addresses you enter, such as your own Calibre, Kavita or Komga server. Close Reader comes with no catalogs, doesn’t host, recommend or check any, and doesn’t control what they offer. You connect them yourself and are responsible for having the right to the books you download from them.

You keep all rights to your files, notes and other content. You allow us to store, copy, sync and process your content only as needed to provide the Service to you, including sending passages to our AI providers when you use an AI feature (see the Privacy Policy). We don’t use your content for any other purpose.

5. AI features

  • AI answers are generated automatically and may be inaccurate, incomplete or out of context. Check anything important against the book or other sources. They are not professional (for example, legal, medical or academic) advice.
  • “No spoilers” mode limits what the AI receives to the part of the book you have read. It greatly reduces the risk of spoilers, but we can’t guarantee that an answer will never reveal or guess something from later in the book or from the model’s general knowledge.
  • Answers that look things up on the web link to the pages they used. Those sites belong to others: we don’t control or check their content and aren’t responsible for it.
  • AI features use energy (section 7). You must not try to get around energy limits, for example by automating requests or resetting identifiers.
  • You must not use the AI features to create unlawful, harmful or infringing content.
  • If an answer is offensive, harmful or wrong, please report it in the app (the flag under the answer).

6. Acceptable use

You must not misuse the Service. In particular, you must not interfere with its operation or security, access it by automated means other than the app, access other users’ data, reverse engineer it except where the law allows, or use it to break the law.

7. Plans, energy and payments

  • AI features use energy (⚡). The free plan gives a one-time starter amount of energy for the first 7 days after you first open the app (signing in to an account doesn’t start them again); what’s unused then expires, and after that the free plan gives no energy. Each paid plan gives a set amount of energy each month; paid plans differ only in that amount. An action costs as much energy as the AI work it takes: a word translation and a page of chapter summary cost 1 ⚡ each, and a question about the book costs more the more of the book it draws on. On a paid plan, a single action costs no more than 500 ⚡: we cover the rest, up to a quarter of the plan’s monthly energy each month, and after that actions cost their full price until the next month. The app shows your balance, and the price of larger actions before you take them.
  • A month’s energy doesn’t carry over to the next month. Energy you buy separately doesn’t expire and is used once the month’s energy runs out. Energy has no cash value and can’t be transferred, exchanged or refunded except through the store. It belongs to your account or, if you don’t sign in, to the app on your device.
  • Subscriptions (monthly or yearly) are sold through the App Store or Google Play and renew automatically until you cancel them in your store account settings at least 24 hours before the end of the current period. A free trial, when offered, becomes a paid subscription unless you cancel before it ends. The store takes the payment and handles cancellations and refunds under its own terms; if the store refunds a purchase, the plan or energy it gave is withdrawn. Any right of withdrawal you have as a consumer is exercised through the store.
  • We may give a plan or energy as a gift, for example to beta testers. A gift lasts until the date shown in the app and doesn’t renew.
  • Prices are shown in the app, in your store’s currency, before you buy. We may change prices or the energy of plans for future periods; the store asks for your consent where that is required.
  • To get your subscription on a new device or after reinstalling the app, sign in or use “Restore purchases”. Energy bought without signing in stays on that device and may be lost if you delete the app, so we recommend signing in.
  • Deleting your account doesn’t cancel a subscription: cancel it in your App Store or Google Play settings.

8. Our rights

The app, its design, name and logo belong to us or our licensors. We give you a personal, non-exclusive, non-transferable, revocable licence to use the app on devices you own or control, in line with these Terms and the rules of the store you got it from.

9. Third-party services

The Service relies on third parties, such as app stores, sign-in providers and our hosting and AI providers. Their terms may also apply to you, and we are not responsible for services we don’t control.

10. Disclaimer

To the extent permitted by law, the Service is provided “as is” and “as available”, without warranties of any kind, including fitness for a particular purpose and uninterrupted or error-free operation. Keep your own copies of your books; we are not a backup service.

11. Limitation of liability

To the extent permitted by law, we are not liable for indirect or consequential damage, lost profits or lost data, and our total liability for any claim relating to the Service is limited to the greater of the amount you paid us in the 12 months before the claim or 50 EUR.

Nothing in these Terms excludes or limits liability for damage caused intentionally or through gross negligence, for injury to life, body or health, or any liability that cannot be excluded under applicable law, and nothing limits your mandatory rights as a consumer.

12. Suspension and termination

You can stop using the Service and delete your account at any time. We may suspend or end your access, in whole or in part, if you seriously or repeatedly break these Terms or if required by law; where reasonable, we will tell you first. We may also discontinue the Service, giving reasonable notice where possible.

13. Changes to these Terms

We may update these Terms. We will post the new version here and, for significant changes, tell you in the app or by email before they take effect. If you keep using the Service afterwards, the updated Terms apply.

14. Governing law and disputes

These Terms are governed by the laws of the Republic of Serbia. Disputes will be resolved by the competent court in Novi Sad, Serbia. If you are a consumer, you also keep the protection of the mandatory laws of your country of residence and may bring a claim in its courts where the law allows.

15. Apple App Store

If you downloaded Close Reader from the Apple App Store, these Terms are between you and us, not Apple. Apple has no obligation to provide maintenance or support, is not responsible for the app or for any claims relating to it (including product liability, legal compliance or intellectual property claims), and, if the app fails to conform to any applicable warranty, you may notify Apple, which may refund the purchase price, if any; Apple has no other warranty obligation. You confirm that you are not located in a country subject to a U.S. Government embargo and are not on any U.S. Government list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
