Privacy Policy

Last updated: May 6, 2025

This Privacy Policy describes how Audiobook Librarian ("we," "us," or "our") collects, uses, and protects information when you use our application and services.

This service is operated in the United States. By using the Service, you consent to the transfer and processing of your information in the United States.

1. Information We Collect

Account Information

When you create an account, we collect your email address and a password (stored as a secure hash). We do not collect your name unless you choose to provide it.

Library and Listening Data

To provide the service, we store information about your audiobook library, including:

  • Titles, authors, and metadata for books in your library
  • Playback position and progress for each book
  • Listening history and bookmarks
  • Your ratings, notes, and custom shelves

This data is associated with your account and synchronized across your devices.

Device and Technical Information

We collect a device identifier to enable multi-device sync and to prevent duplicate event processing. This identifier is generated by the app and resets if you reinstall or clear app data. We do not collect hardware serial numbers, advertising identifiers, or other persistent device identifiers.

Usage Events

We record events such as plays, pauses, and position updates as part of the synchronization system. These events are used solely to keep your library state consistent across devices and are not used for analytics or advertising.

2. How We Use Your Information

We use the information we collect to:

  • Operate and maintain your personal audiobook library
  • Synchronize your library and listening progress across your devices
  • Authenticate your account and keep it secure
  • Respond to support requests

We do not sell, rent, or share your personal information with third parties for marketing or advertising purposes.

3. Your Audiobook Library

Personal and Shared Libraries

Audiobook Librarian is designed for personal libraries. Your library may contain audiobooks that you own, have purchased, or have otherwise obtained the right to use. You may share access to your library with associates (such as family members) who have been granted access by the library administrator. In all cases, it is your responsibility — and that of your library administrator — to ensure that access to any content complies with applicable copyright law and the terms under which that content was obtained.

LibriVox and Public Domain Content

Audiobook Librarian supports libraries that include recordings from LibriVox and other sources of public domain audiobooks. LibriVox recordings are released into the public domain and may be freely used, shared, and distributed. We do not claim any rights over such recordings.

4. Data Retention

We retain your account data for as long as your account is active. If you delete your account, we will delete or anonymize your personal data within 30 days, except where retention is required by law.

Sync event records are retained for a rolling 30-day window to support device synchronization, after which they are deleted.

5. Security

We take reasonable technical and organizational measures to protect your information. Passwords are stored using strong one-way hashing. Data is transmitted over encrypted connections (HTTPS/TLS). However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

6. Your Rights

You have the right to:

  • Access the personal data we hold about you
  • Correct inaccurate data
  • Request deletion of your account and associated data
  • Export your library data

To exercise these rights, contact us at the address below.

7. Children's Privacy

Audiobook Librarian is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us so we can remove it.

8. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify registered users of material changes by posting a notice in the app or by email. Your continued use of the service after changes take effect constitutes acceptance of the updated policy.
