"The information we automatically collect about you relates to the type of device you are using, information that helps us identify your device, how you play our Games, how you interact with our ads, and third-party ads. This includes your approximate geolocation and online identifiers, which do not identify you personally but may uniquely identify your device, and other device data."
The policy collects broad device identifiers, gameplay behavior data, ad interaction data, and other unspecified "device data" automatically, beyond what is strictly needed for core game functionality.
