DrumLock Privacy Policy

Last updated: May 23, 2026

Information Collection and Use

DrumLock is designed with privacy as a core principle. We do not collect, store, or transmit any personal information or practice data to external servers.

Local Data Storage

The following data is stored locally on your device only:

• Practice session history: Duration and date/time of your practice sessions
• Custom practice routines: Routines you create are saved only to your device
• App preferences: Settings like selected sound, time signature, and BPM preferences
• Audio file references: When you add audio files to practice routines, DrumLock stores a reference to the file location on your device. The audio files themselves remain in their original location and are not copied or modified.

Important: This data never leaves your device. It is not backed up to cloud services, and it is not accessible to us or any third parties.

Permissions

DrumLock requests minimal permissions:

• Notifications: Used only for optional speed trainer progress alerts. You can disable this in your device settings at any time.
• Media/file access: Used only to load audio files (MP3, WAV, FLAC) that you select for practice routines. DrumLock reads audio files from your device for playback only. Files are never uploaded, shared, or modified.

DrumLock does NOT request or use:

• Camera access
• Location services
• Contacts access
• Phone call access

Network Activity

DrumLock operates primarily offline. Network activity is limited to:

• Google Play Billing: processing in-app purchases (Pro upgrade)
• Google Firebase Analytics: anonymous usage statistics (which features are used, session counts) so we can improve the app
• Google Firebase Crashlytics: anonymous crash reports and diagnostic information so we can fix bugs

DrumLock does NOT:

• Transmit your practice data, custom routines, or audio files to external servers
• Collect any personally identifiable information
• Include advertising networks
• Sell or share data with third parties for marketing purposes

Third-Party Services

DrumLock integrates with the following third-party services:

• Google Play Billing: Used to process in-app purchases (Pro upgrade). Purchase transactions are handled entirely by Google Play. DrumLock does not store or have access to your payment information.
• Google Firebase Analytics: Used to collect anonymous usage statistics: which features are used, session counts, app version, country, device type. No personally identifiable information is collected. This helps us understand how DrumLock is used and what to improve next.
• Google Firebase Crashlytics: Used to collect anonymous crash reports and diagnostic data (stack traces, device model, OS version) so we can identify and fix bugs.

DrumLock does not integrate with or share data with:

• Advertising networks
• Social media platforms
• Cloud storage services for personal data

Data Security

Since all data is stored locally on your device:

• Your data is protected by your device's security features
• No data can be intercepted during transmission (because no transmission occurs)
• You maintain full control over your data

Data Deletion

You can delete all DrumLock data at any time by:

• Using the "Clear History" feature in the Session tab
• Uninstalling the app from your device (removes all local data)

Children's Privacy

DrumLock does not collect any information from anyone, including children under 13. The app is suitable for all ages and contains no inappropriate content.

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. Continued use of the app after changes constitutes acceptance of the updated policy.

Your Rights

Under privacy regulations such as GDPR and CCPA, you have the right to:

• Access your data (all stored locally on your device)
• Delete your data (via app features or uninstall)
• Export your data (custom routines are saved as JSON files)

Since no data is collected by us, there is no data for us to access, correct, or delete on our end.
