The conversation between human and AI assistant.
How does the Happn app know where my location is when the app is closed on iOS?
But then won't the app be useless if it can't track my location when it's closed?
Not necessarily. Happn primarily uses background location to send you notifications about other Happn users who are nearby to your location. If you don't care about those notifications, you can disable background location and still use the app to browse potential matches and chat with people you've already connected with.
