M4B to MP3 Audio Converter

Effective Date: August 10, 2026

1. Introduction

Welcome to M4B to MP3 Audio Converter ("App", "we", "us", or "our").

This Privacy Policy explains how information is handled when you use the App to browse, convert, save, play, and manage compatible M4B audiobook files.

We designed the App to perform audio conversion directly on your Android device. This means that the audiobook files you select for conversion are processed locally by the App rather than being routinely uploaded to a remote conversion server.

Local processing: Your selected M4B audio files are processed on your device for conversion. We do not use your audiobook files as a source of personal information or intentionally upload them to our servers for conversion.

2. Information We Handle

The App does not require you to create an account to perform ordinary audio conversion.

Audio Files M4B files you select are accessed so the App can read, process, and convert compatible audio content.
File Information The App may process file names, file locations, audio properties, and supported metadata needed for conversion.
Conversion History Information about recent conversions may be stored locally to provide the History feature.
App Preferences Settings such as conversion preferences and application preferences may be stored on your device.

3. Audio File and Storage Access

The App may request access to audio files or device storage so that you can select M4B files for conversion and save converted MP3 files.

Access is used for the functionality you request, such as selecting an audiobook, reading its contents, and saving the resulting MP3 file.

The App does not need access to unrelated personal files to perform an M4B-to-MP3 conversion.

4. Local Audio Conversion

Audio conversion is designed to take place on your Android device. The App may extract audio information, decode the source audio, convert it to MP3, and generate supported metadata and artwork in the output file.

Depending on the source file and conversion settings, supported metadata such as title, artist, album information, and cover artwork may be processed and preserved in the resulting MP3 file.

The App does not intentionally transmit your selected audiobook content to us as part of the normal conversion process.

5. Conversion History

The App provides a conversion history feature so you can view and manage recent conversions.

History-related information may include details such as the source or converted file name and information necessary to reopen, share, delete, or reconvert an item.

This information is intended to be stored locally on your device unless a separate Android feature or service is used by you to share or transfer information.

6. Advertising

The App uses Google AdMob to display advertisements.

Google and its advertising partners may collect or process information such as advertising identifiers, device information, approximate location information, and ad interaction information as permitted by applicable settings and policies.

Advertising information may be used to provide, measure, and improve advertisements, including personalized or non-personalized advertising where applicable.

Advertising practices are also governed by the policies and privacy terms of the relevant third-party advertising provider.

7. Notifications

The App may use notifications to provide application-related information, including conversion or service-related updates, where supported and enabled by you.

Notification permission is controlled through Android system settings. You can disable notifications at any time through your device settings.

8. Background Processing

The App may use Android background or foreground processing mechanisms to continue audio conversion when required by the conversion operation.

This functionality allows longer audio conversions to continue while you use other parts of the device, subject to Android system restrictions and permissions.

9. Internet and Network Information

The App may use an internet connection for services such as advertising, application updates, reviews, notifications, or other supporting services integrated into the application.

Internet connectivity is not intended to be required for the core local M4B-to-MP3 conversion process.

10. Third-Party Services

The App may use third-party services to provide advertising, notifications, application updates, reviews, networking, or related functionality.

These third-party providers may process information according to their own privacy policies and applicable terms.

11. Sharing and Exporting Files

The App may provide Android sharing functionality so you can share or export converted MP3 files.

When you choose to share a file, Android may provide the file to the application or service you select. Information shared through such an action is controlled by you and the receiving application or service.

Your choice: File sharing is initiated by you. We do not automatically publish or distribute your converted audio files.

12. Data Security

We take reasonable measures to limit unnecessary access to information handled by the App.

Because the App processes selected audio files locally, your audiobook content is not routinely sent to our servers for conversion.

However, no software, device, storage system, or transmission method can be guaranteed to be completely secure.

13. Data Retention and Deletion

Locally stored conversion history and application data may remain on your device until you delete them, clear the relevant history, uninstall the App, or otherwise remove the associated application data.

Converted MP3 files are separate files saved according to the location and actions you choose. Removing conversion history does not necessarily delete MP3 files that you previously saved.

14. Children's Privacy

The App is a general-purpose utility and is not specifically directed toward children.

We do not knowingly request personal information from children for account creation or registration.

15. Your Choices

16. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes to the App, its services, or applicable requirements.

When changes are made, the updated policy will be published on this page together with a revised effective date.

17. Contact Us

If you have questions, concerns, or requests regarding this Privacy Policy or the privacy practices of the App, please use the contact information provided on the application's Google Play Store listing.

18. Important Notice

M4B to MP3 Audio Converter is a file-conversion utility. You are responsible for ensuring that you have the necessary rights or permissions to convert, reproduce, save, or share the audio content you process with the App.

The App does not claim ownership of the audio files you select or the content contained within them.
