None. The app has no server and no account system; we — Digiras — do not collect, store, or receive any personal information from you. The app sends no data over the internet.
The app listens to your instrument through the microphone only while the tuner screen is active, to detect the pitch of the note you play. Audio is processed in real time, entirely on your device, and is never recorded, saved, or transmitted. No audio ever leaves your phone. When the app goes to the background, the microphone is released. If you deny the microphone permission, the app still works in reference-tone mode.
Your preferences (A4 calibration, instrument preset, language) and simple usage counters (e.g. how many tunes you completed) are kept only in local storage on your device. They never leave your phone and are deleted when you uninstall the app or clear its data.
This version of the app contains no ads and uses no advertising data, including the Advertising ID. If a future version adds optional rewarded ads, this page will be updated with a new effective date and the Google Play Data Safety declaration will be updated in the same release.
The app is suitable for general audiences, collects no data from anyone, and contains no ads, purchases, or external links inside the app experience.
If we change this policy, we will update this page and its effective date. Material changes (such as introducing ads) will always ship together with an updated Google Play listing and Data Safety declaration.
