"This information includes things like your device type and carrier name, crash reports, which apps you've installed, and, depending on your device settings, other information about how you're using your Android device. If you use our services to make and receive calls or send and receive messages, we may collect call and message log information like your phone number, calling-party number, receiving-party number, forwarding numbers, time and date of calls and messages, duration of calls, routing information, and types and volumes of calls and messages."
Google collects a wide range of device data including installed apps, call and message logs with full metadata (numbers, times, durations, routing), carrier information, and usage patterns โ much of which goes beyond core service functionality.
