Privacy Policy
This policy explains what information Isola ("the app", "we") handles. In short: your songs, separated tracks and recordings are processed on your device and are never uploaded by us. The app uses Google Analytics for Firebase, Unity Ads and Google Play Billing, which process limited technical data as described below.
Songs and separated tracks
When you pick a song or video (or share one to Isola), Android gives the app access to that file. Isola copies it into the app's private storage and separates it on your device with an on-device AI model. Separated tracks stay in the app's private storage until you delete them, save them to your Music folder or share them. If you import from a link you type, the file is downloaded directly from that address to your phone.
Microphone
The microphone is used only in Karaoke maker, while you record a cover. Recordings are stored only in the app's private storage until you delete, save or share them.
Notifications
If you allow notifications, Isola shows at most one local reminder a day (tips and the free-trial offer) to users without a subscription. Reminders are scheduled on your device; you can turn them off in Settings.
