Logger collects no data. It has no account and no sign-up, no ads, no analytics, no tracking and no code from anyone else. The developer never sees your books.

Your books

Logger keeps your books on your device. When you’re signed in to iCloud, it also keeps them in your own private iCloud database (Apple’s CloudKit), so that they’re the same on every iPhone and Mac signed in to your Apple Account. Every field of every book is end-to-end encrypted with keys in your iCloud Keychain: no one but you can read your books, not even Apple.

Without iCloud, your books stay on the device.

Which of a book’s details you turn on in Settings is kept in your iCloud too, so that it’s the same on your devices.

What you export

A JSON file or a PDF diary you export goes only where you send it.

Deleting your books

Settings › Delete Everything deletes every book from the device and from your iCloud, and so from every device signed in to it.

Children

Logger collects nothing from anyone, children included.
