I checked these sites.
https://developer.apple.com/app-store/user-privacy-and-data-use/
https://developer.apple.com/app-store/app-privacy-details/#user-tracking
I would like to know more information about IDFA.
Who assigns IDFA value to where (ex. Apple to the device or Apple to the user Apple ID)
And I want to know what information an app with tracking permission can know.
ex. Email address, gender, age, etc...
Where can I find out what kind of data is being shared by allowing tracking permissions?
Apple developer support service was not helpful.
