You can request deletion of your Jetpack IPTV account and the data associated with it.
When we fulfill a deletion request, we remove account-related data stored on our servers, such as linked devices, synced preferences, favorites, and watch history associated with your account.
Uninstalling the app on your device removes local app data on that device. Purchases made through Google Play or the App Store are managed by those stores and are not deleted by us.
