Harmonica Studio is built so that the most sensitive thing about you — the sound of you practising — never leaves your device.
Listening, tuning, and grading run entirely on your iPhone. No audio recording or microphone data is ever uploaded to our servers. Our backend has no audio endpoints at all.
The app uses Apple's StoreKit service to show, purchase, and restore subscriptions. Apple processes those transactions under its own privacy policy. Harmonica Studio does not send purchase receipts, practice results, imported tabs, or an app-created identifier to our server.
Your lesson progress, imported tabs, and practice milestones are stored on your device. We cannot read them.
Delete the app to remove its on-device practice data and imported tabs. Subscription records are managed by Apple; you can manage them in iOS Settings.
Harmonica Studio is not directed at children under 13 and does not collect personal information.
