My app was rejected because I did not have a Privacy Policy: "Apps that include account registration or access a user’s existing account must include a privacy policy or they will be rejected".
I saw related question here: Apple store rejected iOS application due to background modes but not quite the same as my question, so I create a new one.
My app uses ShareKit to connect to Facebook, Youtube, and configured for using OAuth 2.0. Is there anyway for my app to access to user data like username or password? I think not.
I understand that from my view (developer), my app cannot access those user data. But from user's perspective, they only see that my app request them to enter their credential.
So what kind of contents my Privacy Policy should have? (I have apps that also use ShareKit to post to Facebook before, but this time they rejected).
