App Store Upload rejection about guideline 4.8, third party logins

I received a rejection message from the iOS App store when submitting an app, but the technical and feature requirements for getting the app accepted are not clear.

This is the message that the app store replies:

As for the guideline 4.8, your in app login is fine but your “third party logins” like google and Facebook logins do not follow all the three points listed below:

• The login service limits data collection to the user’s name and email address.
• The login service allows users to keep their email address private as part of setting up their account.
• The login service does not track users as they interact with your app.

How do I get the app to meet the requirements? I have already met the criteria in the following way.

• "The login service limits data collection to the user’s name and email address" - I already use only those two pieces of data.
• "The login service allows users to keep their email address private" - My app doesn't show users’ email address in public.
• Does ‘the login service does not track users as they interact with your app.’ mean I have to ask users about option not to track them when they’re signing up?

I have sent these questions to the app store asking clarification from them, but they repeat the same answer.

The problem was caused by not having Privacy Policy and Terms of Service when doing social login. I added and they passed.
