Kevin’s Piano Project

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.

Coming soon

Kevin’s Piano Project is being prepared for iOS and Android. This page will remain the public product, privacy, license, and support home as the store releases approach.

Quick start

• Allow microphone access and use a quiet room with the device near the piano’s open lid or a connected measurement microphone.
• Open Sample Piano and capture isolated strings when you want measured inharmonicity anchors for this instrument.
• Open Game Plan, choose Classical, Pop, or Jazz priorities, and review the custom stretch curve from A0 to C8.
• Start the tuning pass, strike one key at a time, and wait for Stable / Locked before moving on.
• Use Voicing for three controlled strikes when you want partial, attack, decay, and neighbor evidence.

Pitch will not lock

Reduce room noise, isolate the string when calibrating, strike consistently, move the microphone closer, and confirm the intended key. The app marks weak, stale, or degraded evidence instead of presenting it as a qualified reading.

External microphone

Connect the interface before starting the session. If the route changes, reopen the listening session and confirm the input label. The iOS build prefers an available external input and reports the active route in the tuner.

Theme and app icon

Choose Ivory Workshop, Concert Instrument, or Optical Lab from the app menu. On supported devices, the Home Screen icon follows the selected theme.
