Apple’s App Review Team is now rejecting apps that use cookie tracking, according to a report. Previously, developers could open Safari to read a cookie, identifying a user’s interaction with ads, but some developers have recently seen rejections for apps using the technique. It’s speculated that Apple is rejecting these apps to increase use of its own Advertising Identifier technology. As Apple notes in its iOS 6 settings, “In the future all apps will be required to use the Advertising Identifier.” Users can opt to limit ad tracking from the Advertising Identifier through advertising, in the About section of iOS 6 settings.
