Your data stays yours. Guaranteed.
Last updated: June 2026
Scoped Storage only. No broad file permissions. No accounts. No telemetry. No ads. No tracking. Just you, your books, and your audiobooks — offline, private, secure.
Most ebook and audiobook apps demand dangerous broad permissions: READ_EXTERNAL_STORAGE, MANAGE_EXTERNAL_STORAGE, INTERNET. They create accounts. They track your reading habits. They sync data to servers you don't control.
LibraVault is different.

Bookmarks, highlights, and position — stored only in a local database. Never leaves your phone.
Folders you explicitly grant via Android's system folder picker. You control exactly what we see.
Enable crash logs if you want — stored on your device only, never transmitted or shared.
If you purchase or donate, a flag is saved locally. No remote verification.
Android's Scoped Storage restricts app file access to specific folders you grant via the system picker. LibraVault cannot access your photos, messages, or other sensitive files — Android physically prevents it.
Most apps still use READ_EXTERNAL_STORAGE / MANAGE_EXTERNAL_STORAGE because they're easier to implement. We rejected that tradeoff.
F-Droid build no INTERNET permission
The F-Droid version has no internet permission at all. BTC and XMR donation addresses are displayed statically; no network calls are made under any circumstances.
Play Store build INTERNET permission
The Play Store version uses the internet for one purpose only: Google Play Billing to process the one-time purchase. No other network calls are made by the app itself.
