Terms of Use

In effect from 10 November 2026.

These terms

These terms cover your use of Calibre Reader and its account: friends, chats, clubs, lending and borrowing, and the other things the account brings. By making an account, you agree to them and to the Privacy Policy. The app itself is licensed to you under Apple's standard licence for apps, which these terms add to.

Your account

• You must be 13 or older to make an account.
• Use your own email address, and keep your password to yourself. You're responsible for what's done with your account.
• Your name mustn't pretend to be someone else, or another reader.
• You can delete your account at any time, in the app under Account › Delete Account.

The rules for chats, clubs and profiles

There is no tolerance for objectionable content or abusive people. You may not post, send or share:

• harassment, bullying, threats, or anything meant to frighten or hurt someone;
• hate, or attacks on people for who they are: their race, ethnicity, religion, nationality, gender, sexuality, disability or age;
• sexual content, and anything at all that sexualises children;
• graphic violence, or anything that encourages violence, self-harm or crime;
• spam, scams, advertising nobody asked for, or links to malware;
• anyone's private information without their consent;
• books, files or other work you don't have the right to share. Lend and send only books you may: your own DRM-free books, or books in the public domain.

Clubs may have rules of their own, which their administrators set. A club's rules add to these terms and can't loosen them.

Reporting and blocking

• Report: hold a message to report it, or report a reader from their profile. Reports go to the Calibre Reader administrators.
• Block: block a reader from their profile or from your chat with them. They can no longer message you, call you, or ask to be your friend. You can unblock them under Account › Blocked Readers.
• What we do: we look at every report within 24 hours. Content that breaks these rules is removed, and anyone who posted it may be muted, removed from clubs, or have their account blocked.

What you post

What you write and send stays yours. You give us permission to keep it and deliver it to the people you send it to, as the app does, for as long as it's on the server. You're responsible for what you post.

Purchases

Tips and the Lifetime supporter purchase are made through Apple, under Apple's terms, and support the app's work. Being a supporter raises the app's limits (more libraries and themes) and removes the ad; it buys no books or other content. Refunds are handled by Apple. What supporting costs and brings, and what a refund takes back: Supporting Calibre Reader.

Your libraries

Calibre Reader reads the libraries you connect: your own servers and storage. What's in them, and your right to read it, are yours to look after. Calibre Reader is independent, and not affiliated with calibre, calibre-web, or the other services it can connect to.

If things go wrong

We work to keep Calibre Reader running well, but it comes as it is, without guarantees, as far as the law allows. We may change or stop parts of the service. We may suspend or close an account that breaks these terms.

Changes

When these terms change, the new version will be posted here with its date. If a change is important, we will also say so in the app.
