Privacy Policy

Last updated: July 4, 2026

Audiobook Player is designed so your audiobook library stays under your control. Your book files, playback positions, bookmarks, and preferences are stored locally on your device by default.

Local Data Storage

Audiobook files you import are stored on your device or accessed from locations you choose, such as Files, iCloud Drive, local folders, ZIP archives, or WiFi upload. Your library, playback positions, bookmarks, and settings are stored in the app sandbox.

iCloud Progress Sync

If you enable iCloud progress sync, audiobook progress metadata is synced through Apple's iCloud Key-Value Storage to your own iCloud account. Audio files are not uploaded by this feature.

Connected Services

If you choose to connect an external service, Audiobook Player communicates with that service only to browse, stream, or download the audiobooks you select.

  • Put.io: The app communicates with Put.io servers when you connect your account. Credentials are stored in the iOS Keychain.
  • Google Drive: The app communicates with Google Drive APIs when you connect your account. OAuth tokens are stored in the iOS Keychain.
  • WebDAV: The app communicates with the WebDAV server you configure. Credentials are stored in the iOS Keychain.
  • LibriVox: The app can browse, stream, and download public-domain audiobook files from LibriVox and Archive.org sources.

Google Drive Access

When you connect a Google Drive account, Audiobook Player requests read-only access (the drive.readonly scope) so you can browse your Drive and import audiobooks. This section explains how that information is accessed, used, stored, and shared.

  • What we access: the names and folder structure of your Drive items, so they can be shown in a browsable list, and the contents of the specific audio files you choose to import.
  • How we use it: solely to let you find and download audiobooks into the app. We do not use Google user data for advertising, and we do not use it to train machine learning or AI models.
  • How we store it: downloaded audiobooks are saved on your device. Your Google sign-in (OAuth) tokens are stored only in the iOS Keychain on your device. We operate no server of our own, so your Google Drive data is never transmitted to, or stored on, infrastructure we control.
  • How we share it: we do not sell, transfer, or share your Google user data with anyone. Data moves only between Google and your device.
  • Retention and deletion: your tokens are deleted from the Keychain as soon as you disconnect Google Drive or sign out, which immediately revokes the app's access.

Audiobook Player's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Data Security

Audiobook Player uses industry-standard measures to protect your data, including the sensitive data accessed through connected services such as Google Drive.

  • Encryption in transit: all communication with Google Drive and other connected services is performed over encrypted HTTPS/TLS connections. Your data is never transmitted over unencrypted channels.
  • Encryption at rest: your Google sign-in (OAuth) tokens and any service credentials are stored in the iOS Keychain, which is hardware-encrypted by the operating system. Downloaded audiobooks, your library, playback positions, and settings are stored inside the app's private sandbox, protected by iOS Data Protection (file-level encryption tied to your device passcode).
  • No servers, no third parties: the app operates no backend of its own. Sensitive data moves only directly between your device and the service you connected. It is never routed through, stored on, or shared with infrastructure we control or any third party.
  • Least-privilege access: the app requests read-only access and reads only the audiobook files you explicitly choose to import. It never modifies or deletes your Drive content.
  • Revocation and deletion: disconnecting a service or signing out immediately deletes the stored tokens and credentials from the Keychain, which revokes the app's access.

Anonymous Usage Analytics

Audiobook Player uses TelemetryDeck for anonymous usage analytics to understand which features are used and to improve the app. Analytics can be disabled in Settings.

  • Collected: anonymous usage signals, bucketed event parameters, a daily-rotating anonymous hash, and basic system metadata such as app version, OS version, device model, locale, and region.
  • Never collected: book titles, author names, file names, file paths, audiobook content, account passwords, or personal contact information.
  • Processing: TelemetryDeck processes analytics on servers in the European Union and does not create individual user profiles.
  • Opt-out: You can disable usage analytics at any time in the app settings. When disabled, no new analytics signals are sent.

No Advertising Tracking

Audiobook Player does not include advertising SDKs, does not sell user data, and does not track users across apps or websites.

Children's Privacy

Audiobook Player does not knowingly collect personal information from children.
