Ottershelf

Copyright (C) 2026 the Ottershelf contributors.

Ottershelf is an Android reading app for self-hosted BookOrbit servers. It is a modified version
of BookOrbit: it contains material from BookOrbit (its vendored foliate-js reader, and code
ported from its web client and API types). This is a modified version of BookOrbit and is not an
official BookOrbit release. It is not approved, sponsored or endorsed by the BookOrbit project.

Ottershelf is free software: you can redistribute it and/or modify it under the terms of the GNU
Affero General Public License, version 3 only (LICENSE), together with BookOrbit's additional
terms (ADDITIONAL_TERMS.md), as permitted by section 7 of that licence. It is distributed without
any warranty. Third-party components keep their own licences (THIRD_PARTY_NOTICES.md).

Modifications: the files under app/src/main/assets/foliate/ are BookOrbit's copy of foliate-js,
changed for this app; the changed lines are marked "[bookorbit-android]". The app's Kotlin code
ports parts of BookOrbit's web client (each file names the BookOrbit source it follows). The git
history of this repository records every change and its date.
