Where is my data stored
Your library data is stored locally on your device. When you connect with friends, only the books you choose to share are visible to them. You can export a backup anytime from your Profile.
Local storage
All your data (books, shelves, loans, contacts) is stored in a local database on your device. Nothing is sent to a remote server.
Controlled sharing
When you connect with other libraries, you maintain full control over what is shared. Only the books you choose to make visible are visible.
Backups
Export a backup of all your data at any time from the Profile section. You can also re-import them when switching devices.

Encryption
Communications between libraries are end-to-end encrypted (E2EE). Your data stays private.
