Researchers from Mysk questioned the privacy of the company and proved that Apple's tool can reveal information about the user.
Detailed analytics of activity in the Apple App Store can be linked directly to an Apple account, according to developers from Mysk on Twitter. According to them, this happens using the DSID tool (Directory Services Identifier, directory service identifier).
This tool is associated with Apple ID and iCloud and can be used by Apple to collect information about the user and identify patterns of behavior in the App Store. All collected information can be used by the IT giant for its own purposes and even sent to third parties.
The most interesting thing here is that Apple does not violate any of its privacy rules, since the App Store and Privacy section contains the following lines: “In order to find new ways to improve stores, we use information about your online activity, purchases, search queries and downloads. This information is stored along with your IP address, a random unique identifier (if applicable), and your Apple ID if you are signed in to the App Store or another Apple online store.”
In addition, it is not clear what information Apple sees. As Gizmodo explains, Apple encrypts usage data and doesn't necessarily process personal and public information together. But the main problems are that Apple does not describe its methods for collecting analytical data, and some tracking tools (the same DSID, for example) cannot be disabled. Therefore, there are concerns that the company may violate its promises regarding user privacy, even if the information collected is limited.
