Longplay collects no data about you or what you play through it. The app is distributed through Apple’s iOS App Stores, where you are subject to the default, anonymous App Analytics and crash reporting collection provided by Apple. You can opt-in to or opt-out of this when prompted via iOS.
Longplay does not use any third-party analytics or crash reporting services.
