Apple is ratcheting up a tug-of-war over privacy with Facebook. And shut off Facebook’s ability to use internal iOS Apps.

On the heels of a report outlining ways Facebook Inc. is collecting data, Apple Inc. revoked a key set of testing tools that the social networking giant uses to ensure its apps are ready for use on the iPhone and iPad. The move also shut down internal apps that Facebook employees use every day.

The iPhone maker’s decision follows the revelation that Facebook circumvented Apple’s App Store distribution rules by paying users, including teenagers, to share personal data. Facebook shut down the program after TechCrunch reported the news, even as it defended the effort saying users opted in and that the teens had parental consent.
