OzzBooks privacy policy

Last updated: October 27, 2026

OzzBooks is a personal audiobook, ebook and comic player run by James Osborn for his family and a small number of invited friends. You need an invitation to make an account. This page explains what information the app and its account service keep, and what happens to it.

Your account

• Your email address and a hashed password (the password itself is never stored or readable). The invitation code you used is kept in hashed form too.
• Your account is stored in a database hosted by Neon (neon.tech). The account service itself runs on a computer in the administrator's home.

What your account keeps so it works on all your devices

• Where you stopped in each book, bookmarks, notes and highlights, your library shelf, playlists, and your playback and reading settings.
• Which books you have downloaded to each device, and when you last played them.
• The list of sources you add (for example a WebDAV server or a Google Drive folder): their type, a name, the address, and the username. The list follows your account to your other devices.
• For accounts the administrator has given access to the family's OzzBooks file server, a personal key for that server.

The administrator can see which accounts exist and can see the data above. The administrator does not read the content of your files or the books you have on your own sources.

What stays on your device

• Passwords for your sources (such as a WebDAV password) and Google sign-in tokens are saved in the iOS Keychain on your device. If iCloud Keychain is on, Apple syncs them between your own devices. They are never sent to the OzzBooks account service.
• Downloaded books, covers and folders you pick in Files stay on the device. Folders you pick in Files are not shared with other devices.
• If more than one account is used on the same device, each account keeps its own list and settings. A downloaded file is stored once on the device and may be used by more than one account.

Books and files from your sources

When you add a source, the app connects directly from your device to that source (for example your own NAS or Google Drive) to list and play the books. OzzBooks does not copy your books to its account service.

What Google Drive is used for

• Read-only access to files in Google Drive (the drive.readonly permission), so the app can find the audiobooks and ebooks in the folder you choose and play them.
• The email address of the Google account, shown in the app so you can tell which account is connected.

OzzBooks never changes, deletes or uploads anything in Google Drive. In the iOS app the Google tokens are kept on your device, as described above. If the administrator connects Google Drive to the family's own OzzBooks file server, the tokens for that connection are stored encrypted on that server.

What is not done

• Your information, including information from Google, is not sold, shared or given to anyone outside the OzzBooks account service and file server described here.
• It is not used for advertising, profiling or analytics, and the app has no advertising or tracking.
• Only the services described on this page, and Apple's own services (TestFlight, the App Store, iCloud) when you use them, handle your information.

Google API Services User Data Policy

OzzBooks's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Disconnecting and deleting

• You can remove any source in the app (Settings, My Sources), or remove Google's access at myaccount.google.com/permissions.
• You can delete your account in the app (Settings, Account, Delete Account), or by emailing the address below. Either way, the account and everything stored with it is deleted from the account database, including your positions, bookmarks, notes, playlists, shelf and source list. Deleting in the app also removes that account's downloads and saved passwords from the device.
• Removing the app deletes the downloads and the Keychain items kept only on that device.

Changes

If this policy changes, the date at the top changes. Material changes will be explained to account holders before they take effect.
