So I am about to publish a mobile app and I need a privacy policy, although my app doesn't really collect any type of user information, is there some kind of definition about what it means to "collect" in these cases?
Is it considered collecting if I log the user onto her social media and show her some social media api informations and I only save locally (inside her mobile) her social media authentication cookie? My app (and I) would have practically no knowledge of anybody's personal data as soon as I don't send anything outside the device (to a remote database or else)
