17.2 - Apps that require users to share personal information, such as email address and date of birth, in order to function will be rejected
17.2 Details
We noticed that your app uses Kakao/Facebook/Naver login for authentication purposes but does not include account-based features offered by that site, which does not comply with the App Store Review Guidelines.
In order to use Kakao/Facebook/Naver for authentication, your app must include significant account-specific functionality from Kakao/Facebook/Naver. For example, your app should include sufficient account-based features from Kakao/Facebook/Naver other than pulling profile information or sharing on the user’s page.
Next Steps
Please revise your app to implement your own authentication mechanism, or incorporate significant account-specific functionality from Kakao/Facebook/Naver.
If your app does include additional account-specific features from Kakao/Facebook/Naver, please provide us with details on where we can locate these features in your app.
