Piano Pulse is developed by kovaserv. For any question about this policy, contact us at: info@kovaserv.fr.

What data do we collect?

Piano Pulse does not collect, store, or transmit any personal data to a remote server. We don't know who you are. We have no user database.

Data stored locally on your device

For the app to work, some data is saved in the app's private sandbox (iOS SharedPreferences, isolated from other apps):

• App settings: volume, default tempo, note naming (C/D/E or Do/Re/Mi), haptic feedback, etc.
• Local profile: a display name you choose (default "Pianist") and an emoji avatar. Never transmitted.
• Practice stats: daily and global practice time, streak of consecutive days, score and accuracy per song.
• Library: list of MIDI files you have imported and your favorites.
• Imported MIDI files: files you choose to import are copied into the app's private folder so you can replay them offline.
• Unlocked achievements: the list of badges you have earned.
• Premium status: subscription state if you purchase an in-app product.

All of this data is wiped automatically when you uninstall the app.

Permissions requested

• Bluetooth: only to connect a wireless MIDI keyboard (BLE-MIDI). No location data is collected through Bluetooth.
• File picker: to let you import your own MIDI files. We only read files you explicitly select.

The app does not request access to the microphone, camera, contacts, location, or photos.

Third-party services

Piano Pulse uses Firebase Analytics (Google) to understand how the app is used, only if you explicitly enable it. Opt-in is off by default — you can enable or disable it any time in Settings → Privacy → Help improve Piano Pulse.

When enabled, Firebase collects aggregated usage events (e.g. song started, MIDI import succeeded or failed, paywall shown, in-app purchase succeeded, achievement unlocked). Collected data is always aggregated and anonymized via buckets — never the MIDI filenames you import, your display name, the musical content, or precise durations.

Anonymous user properties collected: tier (free or premium), app language, MIDI keyboard connected (yes/no), imports count bucket (e.g. "4-10"), best streak bucket (e.g. "7-13 days"), preferred notation (letters or solfège).

Firebase uses an anonymous install identifier — not tied to your Apple ID or email. IP addresses are truncated by Firebase by default. Data is retained according to Firebase's policy (default 14 months, possibly reduced in Firebase settings). Google's policy applies: firebase.google.com/support/privacy.

For in-app purchases (Premium subscription), transactions go through the Apple App Store and are subject to Apple's privacy policy. Piano Pulse receives only an anonymous identifier from Apple confirming your purchase — never your name, email, or payment details.

Your rights (GDPR)

Since we collect no personal data, GDPR rights (access, rectification, erasure, portability, objection) are automatically respected: there is nothing on our side to access or delete. To erase your local data, simply uninstall the app, or use the "Reset progress" button in Settings.

Children

Piano Pulse is rated "Everyone" (PEGI 3, iOS 4+) and contains no inappropriate content. The app is designed to be usable by children with no privacy risk, since no data is collected.

Policy changes

This policy may be updated to reflect changes to the app (e.g. new features or a third-party service). On significant changes, we will update the "Last updated" date at the top of this page. If we ever introduce telemetry or analytics, this will be clearly announced in the app before activation and will require your explicit consent.
