As reported by Reuters, Poland's antitrust watchdog, the Office of Competition and Consumer Protection (UOKiK), has initiated an investigation into Apple. The focus is on determining whether Apple's App Tracking Transparency (ATT) policy creates an undue restraint on competition within the mobile advertising sector. Rolled out in April 2021 as part of the iOS 14.5 and iPadOS 14.5 software updates, this policy mandates that all iPhone and iPad apps secure explicit user permission prior to tracking user activities across different applications.

More specifically, apps intending to track users through the device's unique advertising identifier (IDFA) are now required to first obtain user consent. Prior to the ATT policy's introduction, the IDFA was automatically enabled. However, following its implementation, users encounter a pop-up prompt requesting tracking permission upon first launching an app. Additionally, they have the option to globally disable tracking requests for all apps through the system settings. The investigation by Poland's UOKiK is centered on ascertaining whether this policy unfairly restricts market competition.
