Privacy policy

STPZKB · Last updated 23 October 2026

STPZKB does not collect any data. We cannot see who uses it or how.

No account, no sign-in, no analytics, no tracking, no ads and no purchases inside the app.
Your progress (lessons, rounds, scores and settings) is kept on your device. If you use iCloud, it is also kept in your own iCloud account, in its private storage for STPZKB, so your other iPad or Mac can show the same progress. Apple stores it for you; we have no access to it.
Microphone (iPad only): used only to play the sound of a digital piano plugged in by USB, so you hear it and a screen recording includes it. The iPad's own microphone is not used, and the sound is never recorded, stored or sent anywhere.
MIDI keyboards are used only to play notes in the app.
The STPZMX button opens our STPZMX page on the App Store; nothing is sent from STPZKB.
Suitable for children: STPZKB asks for no personal information.
