Terms of use

Last updated: November 4, 2026

These terms apply to the Foldbook app, its optional account, Foldbook Server and the relay.foldbook.app relay. By using Foldbook, you accept them.

What Foldbook does

Foldbook is a reader. It reads files you already own, where you keep them. It doesn't sell, supply or recommend any books, and Believemy has no rights over your files.

Your files and copyright

You alone are responsible for the files you open with Foldbook: you must have the right to read them. Don't add files obtained in breach of their authors' rights.

Sharing

Foldbook Server lets you lend your library to people you invite. You remain responsible for what you share and with whom: sharing must stay within your family or private circle and respect the rights of authors and publishers. Using it to distribute works to the public is forbidden. You can remove someone at any time; they lose access immediately.

Your account

The account is optional and free. You must give a valid email address and keep access to your account to yourself. You can delete it at any time from Settings › Account. We may suspend an account used to distribute works to the public or to disrupt the service, after warning you when possible.

Foldbook+

Foldbook is free to read at home. Foldbook+ is a subscription that unlocks reading your library away from home, through Foldbook Server and the relay, and lending your library to people you invite; they read what you lend them for free. It costs €1.99 a month or €19.99 a year in France, taxes included; elsewhere, the price shown by the App Store or Google Play applies. A launch offer may apply to a first subscription: its price and length are shown before you buy.

Purchase, renewal and cancellation

The subscription is bought on the App Store with your Apple account, or on Google Play with your Google account, and is tied to your Foldbook account. It renews automatically for the same length unless you cancel it before the end of the current period (on the App Store, at least 24 hours before), from the subscriptions in your App Store or Google Play account. Cancelling takes effect at the end of the paid period. Refunds and the right of withdrawal follow the terms of the store you bought from, Apple’s or Google’s. If the subscription ends, your guests lose access to your library through the relay; nothing is deleted on your side.

The service

We do our best to keep Foldbook, the account and the relay running without interruption, but can't guarantee it. Keep your files at home and backed up: Foldbook doesn't host them. We can't be held liable for data lost on your devices or servers, or for how you use the files you share.

Changes

If these terms change, we will update this page and tell you in the app before the new terms apply.

Governing law

These terms are governed by French law. In case of a dispute, write to us first at hello@believemy.com; if no solution is found, you can turn to the consumer mediator listed in the legal notice, free of charge.
