App developers at Mysk claim that analysis shows the detailed analytics data Apple records about what users do in the App Store can be linked directly to accounts.
In a series of tweets on Sunday, Mysk researchers said Apple’s analytics data include a Directory Services Identifier (DSID), which uniquely identifies an iCloud account and is associated with name, email and any other iCloud-related data.
Mysk said the tech giant’s claims in its device analytics and privacy statement that the collected data does not personally identify users is “inaccurate,” and that the App Store continues to send detailed analytics to Apple even when sharing analytics is turned off.
“This means that your detailed behavior when browsing apps on the App Store is sent to Apple, and contains the ID needed to link the data to you,” Mysk said, noting that the DSID is also sent by other Apple apps for analytics purposes.
Mysk said there was no way to stop it.
