"Information we collect when you use... such as the data we receive when you interact with our app (e.g., your purchase records, search history, log data, or actions you take within the App) or information about your device (e.g., your device version, Device ID, Android ID, Google Advertising ID, IDFA, Hardware Serial Number, Device Model, operating system, system language and region, Mac address), and the network information (e.g., your network carrier and network type)."
SUGO collects an unusually broad set of device identifiers including Device ID, Android ID, Google Advertising ID, IDFA, Hardware Serial Number, and MAC address — far more than needed for a social chat app, and useful for persistent cross-device tracking.
