Privacy Policy

Tune Master ("the app") is published as a personal project. This policy explains what the app does with your information. In short: the app collects nothing. 1. Microphone The app asks for microphone access so it can hear your strings for live tuning. Audio is analysed on your device in real time to estimate pitch. Audio is never recorded, stored, uploaded, or shared. If you deny microphone access, live detection is disabled; you can still use manual mode and reference tones. 2. Data stored on your device The app keeps a few settings only on your phone, using the platform's local storage: • theme choice (System / Light / Dark) • selected instrument and string • first-launch date (to measure the 3-month free trial) • whether the one-time Premium unlock was bought This data never leaves your device and is deleted if you uninstall the app. 3. Purchases If you buy the Premium unlock or restore it, the payment is processed entirely by Google Play (Android) or the App Store (iOS) under their own privacy policies. We do not see, handle, or store your payment details — the app only learns from the store whether the unlock is owned. 4. Accounts, analytics, advertising • No accounts: there is nothing to sign up for and no login. • No analytics or crash reporters: the app sends no usage data anywhere. • No advertising: the app shows no ads and uses no ad trackers. • No data is sold or shared with third parties, because none is collected. 5. Children The app contains no user-generated content, chat, or accounts and is suitable for general audiences, including young musicians practising with a parent's device. 6. Changes to this policy If the app starts handling data differently (for example, adding cloud features), this policy will be updated and the new version shipped with the app / published at the listing link. 7.
