Apple may be on the way to controlling more of how advertisers get user information from mobile devices.
According to TechCrunch, unnamed industry sources are saying that Apple's App Review team is denying apps that use "cookie tracking." This could be a signal that the company is going full force into its own Advertising Identifier technology.
Theoretically, the way cookie tracking works on mobile is similar to desktop: a cookie saves data and information on users' browsing history that can be used later by the app or Web site. According to TechCrunch, it was introduced as an alternative to unique device identifier (UDID) tracking, which picked up more user data than most people were comfortable with.
Along with the Advertising Identifier, the company also launched a "Limit Ad Tracking" tool. This tool, which is in the iOS 6 general settings menu, lets users prevent advertisers from hitting them with targeted ads.
With Apple allegedly rejecting apps that use cookie tracking, iOS app developers will most likely have to redesign their apps to be compatible with Apple's Advertising Identifier and also take out all technology using cookie tracking.
Sources familiar with the situation told CNET that Apple is not specifically targeting apps that use cookie tracking. Instead, the company is said to be enforcing guidelines around the user interface design and experience.
