These providers may collect or receive device information, advertising identifiers, approximate location derived from IP address, and ad interaction information, subject to your device settings and applicable consent requirements.

On iOS, access to the Identifier for Advertisers (IDFA) is subject to Apple’s App Tracking Transparency framework. If permission is not granted, advertising may still be shown using non-personalized or contextual methods where available.
