Privacy Policy
Bookend for Audiobookshelf · Last updated: November 4, 2026
In short
Bookend does not collect any personal data. The app has no analytics, no advertising and no tracking, and it sends no data to the developer.
The app
Bookend is a client for Audiobookshelf media servers. You choose the server yourself. Everything the app needs to work stays on your device or goes only to that server:
- Sign-in: your password is sent only to your server when you sign in and is not stored. Server address, username and the access tokens your server issues are kept in the system Keychain on your device.
- Listening and reading: progress, listening time, bookmarks, favorites and a random device identifier (created when the app is installed) are sent to your server so it can keep your devices in sync.
- Downloads: downloaded audio files, e-books and covers are stored on your device and excluded from backups. They remain until you delete them in the app or remove the app.
- Settings such as playback speed or reader theme are stored only on your device.
Your server is operated by you or by its administrator. Their privacy policy applies to the data stored there; the developer of Bookend has no access to it.
The app loads nothing from other parties. Links inside an e-book open in your web browser. If an e-book itself references images on the internet, the reader may load them from that address, just like a browser would.
Apple
The App Store and the operating system are provided by Apple. If you have agreed to share analytics and crash reports with app developers in your device settings, Apple gives the developer anonymous crash reports and usage figures. These are governed by Apple's privacy policy.
This website
This website uses no cookies, no analytics and no external fonts or scripts. When you open a page, technical data such as your IP address, the time, the requested page and your browser's user agent are processed automatically in order to deliver the page and protect it against abuse (Art. 6(1)(f) GDPR). Our web server keeps these access logs for no longer than 14 days.
Two service providers are involved, each processing data on our behalf under a data processing agreement:
- Hetzner Online GmbH, Industriestr. 25, 91710 Gunzenhausen, Germany – operates the server in Germany.
- Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, USA – every request passes through Cloudflare's network, which delivers the page and protects it against attacks. Data may be processed in the USA. Cloudflare is certified under the EU-U.S. Data Privacy Framework, for which the European Commission has adopted an adequacy decision (Art. 45 GDPR).
