Violin Fingering Trainer is a mobile application developed by Mermaidica Labs to help students learn violin fingerings through interactive practice and gameplay. Your privacy is important to us. This Privacy Policy explains how we handle information today and how that may change as new features are added in the future.

1. Information We Collect (Current Version)

At this time, Violin Fingering Trainer:

  • Does not require user accounts

  • Does not collect personal information

  • Does not collect usage analytics

  • Does not display ads

  • Does not process payments

  • Works both offline and online

  • Does not share data with third parties

  • Anonymous usage or performance data (for app improvement)

  • Device identifiers for advertising or analytics (if ads are added)

Any future data collection will:

If future features involve accounts, analytics, payments, or online services, appropriate parental consent mechanisms and child safety compliance (including COPPA and applicable platform policies) will be implemented where required.

4. Offline Usage

Violin Fingering Trainer supports offline functionality. When used offline, no data is transmitted. If future online features are enabled, data transmission will occur only when those features are used while connected to the internet.

Although no personal data is currently collected, reasonable technical and organizational safeguards will be implemented to protect any information collected in future versions of the app.

6. Third-Party Services

Violin Fingering Trainer does not currently integrate with third-party services that collect user data. If third-party SDKs or services are added in the future, this Privacy Policy will be updated to disclose those services and their data practices.

This Privacy Policy may be updated as the app evolves.
Updates will be reflected by a revised “Last updated” date.
Material changes will be communicated within the app when applicable.
