Klavola — Learn Piano Keyboard & Lessons

Privacy Policy

Last updated: 12 October 2026 · App package: com.didapp.piano

In short: Klavola does not collect, store on any server, share or sell any personal data. It has no account, no advertising, no analytics and no third-party SDKs, and it does not request the internet permission — so it has no way to send anything anywhere.

What stays on your device

Your recordings, songs and projects, pads, custom sounds and presets, settings, lesson progress and scores are saved in the app's private storage on your phone. Files you export (audio, MIDI, sheet music, backups) go only where you choose to save or share them. Uninstalling the app removes everything it stored.

Microphone

The microphone is used only for features you start yourself, and only while they run:

Lessons with a real piano — the app listens to which notes you play to follow the lesson.
Tuner — the app listens to show which note you play and how in tune it is. If you tap the tuner's capture button, a few seconds of that sound are saved in the app's own folder on your phone (removed when you uninstall the app) so you can listen back; they are never sent anywhere.
Audio latency test (Settings → Audio diagnostics) — the app listens for its own click for a few seconds to measure the delay.

The sound is analysed on your phone, in memory. It is never uploaded or shared. Android asks for the microphone permission the first time you use one of these features; the rest of the app works fully without it.

Bluetooth

The optional Connect a Bluetooth keyboard screen scans for Bluetooth MIDI instruments, only while that screen is open. It is not used to determine your location. The app works fully without it.

Crash reports

If the app crashes, a short technical report (the error, the app version, the phone model and Android version) is saved on your device. The next time you open the app it offers to copy that report so you can send it to the developer if you wish. Nothing is sent automatically.
