Professional Tuner is a chromatic tuner for iPhone. This page explains what the app does with information on your device.

What we collect

The app does not create an account and does not collect your name, email, or other personal details. There are no ads and no analytics SDKs.

Preferences such as the A4 reference and the selected instrument stay on your iPhone. They are not sent anywhere.

Microphone

The app uses the microphone only to hear a note and show how far it is from pitch. Audio is processed on the device in real time. It is not recorded, stored, or uploaded.

You can revoke microphone access at any time in iOS Settings.

Internet

Tuning works offline. The app does not need a network connection and does not send usage data to a server.
