Help Can't the app extract information like email id etc from identity falling under app permissions?

Can't the app extract information like email id etc from identity falling under app permissions why does it individually ask for email id on signup/login page. I need this information for building my first app.

I have a feeling only Google apps can automatically retrieve your email address (just a guess)
