Privacy policy

Effective 6 November 2026. TuneLog is published by Eastframe Technology LLC.

What we collect: nothing. TuneLog has no account system, no analytics, no advertising, and no crash reporting service. It sends no data to us or anyone else, and it works without an internet connection.

Microphone. TuneLog uses the microphone only while the tuner is on screen. The sound is analysed on your device, a fraction of a second at a time, to find its pitch. It is never recorded, saved, or sent anywhere.

Your settings (calibration, note names, tuning, metronome setup and saved songs) are stored on your device until you uninstall the app.

Purchases are handled by the App Store or Google Play. We do not see your payment details. On Android, the app includes Google Play's billing library, which has the internet permission and connects to Google Play to handle purchases. Google's privacy policy applies to that connection.

Third parties. The app contains no third-party advertising or analytics code. The only external pages it opens are this page and the store's rating page, and only when you tap them.

Children. TuneLog is not directed at children and collects no personal information from anyone.

Changes. A new version of this policy will be published at this address with a new effective date.
