It's being reported today that Apple is facing an investigation in Poland over whether its new rules on privacy and personal data processing for iOS devices violate competition law, Polish antimonopoly watchdog UOKiK said on Monday.

Apple rolled out an update of its iOS operating system in April with new privacy controls designed to limit digital advertisers from tracking iPhone users.

The Polish regulator said Apple's new rules have significantly reduced the ability of third-party apps to obtain personal data in order to send personalized adverts.

"We want to examine whether Apple's actions may be aimed at eliminating competitors in the market for personalized advertising services, the objective being to better sell their own service," UOKiK President Tomasz Chrostny said in a statement.

"We will investigate whether this is a case of exclusionary abuse of market power." For more, read the full Reuters report.

Last week Patently Apple posted a report titled "A new report claims that Apple has reached a Quiet Truce with Developers over the iPhone's App Tracking Transparency feature." The report noted that "Months after implementing the iPhone's App Tracking Transparency feature, companies including Snap and Facebook have been allowed to keep sharing user-level signals from iPhones, as long as that data is anonymized and aggregated rather than tied to specific user profiles."

Apple's latest moves behind the scenes may have already been implemented to avoid issues with US and international regulator concerns.
