Effective 12 October 2026
TuneGlass does not collect, store or share any data. Not audio, not usage, not identifiers. The App Store privacy label reads “Data Not Collected”, and this page explains why that is accurate.
TuneGlass asks for microphone access to hear your instrument. Audio is analysed in real time on your device to detect pitch. It is never recorded, stored, or transmitted. When you close the app, nothing remains.
TuneGlass Pro is a one-time in-app purchase handled entirely by Apple. Apple processes the payment and keeps the receipt. We receive no personal or payment information; the app only checks with the App Store whether Pro is unlocked for your Apple Account.
Your preferences (instrument, tuning, note names, reference pitch) are stored only on your device and are removed when you delete the app. They are not synced or uploaded.
TuneGlass collects no data from anyone, including children.
If this policy ever changes, the new version will be published at this address with a new effective date. Any change would only ever describe additional protection, never new collection, without a clear notice in the app.
