Books and backups

Before deleting the app or changing devices, export a complete backup from Data Backup & Restore. Local automatic backups are removed with the app. Cloud copies require a successful upload to protect against device loss.

Lifetime Pro

Use Restore Purchases with the Apple Account that made the purchase. Pro unlocks multiple books and shared-book invitations. Sharing requires iCloud. Invited members can join for free.

Data control

Records can be exported and deleted within the app. Deleting a book does not remove exported files or separate backup versions.
