(Bloomberg) -- Apple is ratcheting up a tug-of-war over privacy with Facebook.

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.

Apple’s decision demonstrates both its power over the industry and a longstanding desire to be seen as a champion of privacy. It’s also a headache for Facebook. The move doesn’t impact distribution for consumers via the App Store, but it could mean delays to new versions including the main Facebook app. The shutdown also turned off internal Facebook apps that are used to run the company -- from email to office communications and ordering food from the cafeteria.

Facebook said all of its employee-only iPhone apps are offline and that it’s working with Apple to negotiate the issue. TechCrunch reported that Google is running a data collector similar to Facebook’s app on Apple’s system.

Facebook paid people ages 13 to 35 as much as $20 a month to install the Facebook Research App to track phone and web usage habits, according to the TechCrunch story. The app will be discontinued on Apple’s iOS, though it will continue to run on Android devices.

“This will cause Facebook to actually suffer some consequences for their actions, for the first time in a while,” said Will Strafach, CEO at Guardian Mobile Firewall and a security researcher. “ They have no clear or easy solution to fall back on either. Apple has clearly and unequivocally demonstrated that nobody is above the rules.”

While Facebook confirmed the existence of the program, it took issue with its representation.

“Key facts about this market research program are being ignored,” a Facebook spokesman said in a statement. “Despite early reports, there was nothing ‘secret’ about this; it was literally called the Facebook Research App. It wasn’t ‘spying’ as all of the people who signed up to participate went through a clear on-boarding process asking for their permission and were paid to participate. Finally, less than 5 percent of the people who chose to participate in this market research program were teens. All of them with signed parental consent forms.”
