Overview
Kevin’s Piano Project is designed as an on-device piano tuning and voicing instrument. It does not require an account and the inspected iOS and Android source does not include advertising, analytics, or tracking SDKs.
Microphone use
Microphone access is required to measure piano-string pitch, inharmonicity, partial balance, attack, and tonal decay. Audio is analyzed in memory on the device for the active tuning, calibration, or voicing workflow.
The app does not record microphone audio to a library, upload it to a Kevin’s Piano Project server, sell it, or share it for advertising or model training.
Local session data
The app may store the selected visual theme, pianist style, A4 reference, auto-advance setting, tuning direction, tuning pass, current key, string-count overrides, unison stage, and captured inharmonicity anchors in local device preferences so a session can resume.
This session information stays on the device unless the operating system includes it in a backup that you control.
Network use
The core tuner does not require a network connection. The inspected Android manifest does not request Internet permission, and the inspected iOS source contains no network service for tuning, calibration, voicing, analytics, or accounts.
Platform permissions
On iOS, the app requests microphone access with the explanation that it listens to piano strings to measure pitch, inharmonicity, and tonal decay. On Android, the app requests audio-recording access and may keep the screen awake during a working session.
Children
Kevin’s Piano Project does not knowingly collect personal information from children or any other users because it does not operate a user-account or telemetry service.
Changes and contact
If the released app’s data practices change, this policy and the relevant store privacy disclosures will be updated before the changed behavior is shipped.
