"Combo may collect certain personal data from you and/or your device. Most of this data comes directly from you or your device, such as your unique device ID (persistent/non-persistent), your device operating system, version, model, CPU, amount of RAM and disk space, hardware type, Identifier For Advertising (IDFA for IOS devices and GAID for Android devices), advertising ID, the version of your operating system ("OS"), your device name, game center ID, and your location based on your Internet Protocol ("IP")."
The app collects an extensive range of device data including hardware specs (CPU, RAM, disk space), persistent device IDs, advertising identifiers, and game center IDs — much of which goes beyond what is needed for core game functionality.
