Welcome to M4A Audio Compressor. We respect your privacy and are committed to protecting any information you may provide while using our application. This Privacy Policy explains our practices regarding data collection, use, and disclosure.
1. Information We Collect
🔒 We do NOT collect any personal data.
M4A Audio Compressor operates entirely offline and does not transmit any information from your device.
Our app processes audio files locally on your device. We do not:
- Collect personal information (name, email, phone number)
- Access your contacts or call logs
- Track your location
- Upload your audio files to any server
- Use analytics or tracking services
- Display personalized advertisements
2. Permissions We Request
Our app requires the following permissions to function properly:
- Read Media Audio (Android 13+): To access audio files you select for compression.
- Read External Storage (Android 12 and below): Fallback permission for older Android versions to access audio files.
- Foreground Service: To continue compression when the app is in the background.
- Post Notifications (Android 13+): To show compression progress and completion notifications.
We only use these permissions for the stated purposes. Audio files are processed locally and never leave your device.
3. Data Storage
All data is stored locally on your device:
- Compressed Files: Saved to your device's internal storage in the app's private directory or Downloads folder (when you choose to save).
- Compression History: Stored locally for your convenience and can be cleared at any time.
- App Preferences: Your settings (default quality, notification preferences) are stored locally on your device.
4. Third-Party Services
M4A Audio Compressor does not integrate any third-party services that collect user data. We do not use:
- Google Analytics
- Facebook SDK
- Advertising networks
- Crash reporting services that collect personal data
5. Data Security
Since all processing occurs locally on your device and no data is transmitted to external servers, your audio files and personal information remain secure on your device. We recommend:
- Keeping your device's operating system updated
- Using device security features (PIN, fingerprint, etc.)
- Only downloading the app from official sources (Google Play Store)
6. Children's Privacy
M4A Audio Compressor does not knowingly collect any information from children under 13 years of age. The app is rated for "Everyone" and contains no content inappropriate for children. Since we don't collect any personal data, children can safely use the app under parental supervision.
7. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last Updated" date. We encourage you to review this Privacy Policy periodically for any changes.
8. Your Rights
Since we don't collect personal data, there is no personal information to access, modify, or delete. You can:
- Clear compression history within the app at any time

- Revoke permissions through your device's settings
