iOS developers say Apple’s App Store analytics aren’t anonymous

The finding exposes the difference between the privacy policy you may think you’re covered under and the privacy policy that’s actually being applied.
The detailed analytics data Apple records about what you do in the App Store can be tied directly to your Apple account, according to app development and research team Mysk. In a Twitter thread, Mysk shows that Apple sends what’s known as a “Directory Services Identifier” along with its App Store analytics info and argues that the identifier is also tied to your iCloud account, linking your name, email address, and more.
