What information can I get about my iOS customer

Question

I want to know what identifying information I will be able to send to my web server from my iOS app.

I have searched the Apple Developer website to answer this question but I cannot seem to find anything.

This is the type of information I am interested in:

• Unique Identifier
• First Name
• Last Name
• Email Address
• Age
• Address

Answer 1

There is absolutely no information at all about the user of your app available through any public API.

If you want anything you need to provide a form in your app that the user can fill in.

And any app asking for such information will quickly be deleted by a user unless the information is critical to the app's functionality.

Answer 2

You really can't get any of that information from the system directly. If you need that info, you should ask the user to create an account for your application and have them enter the info. That's the best way to get the users permission and not get into hot water with privacy issues.
