The application that you are using (or will be using) does not send any usage data or anything else to me. I have no idea what are you doing with my app on my own.
However, it does send your device model and Android version to Sky servers to conform with the protocol requirements
Also, Google (the distributor of the application) does collect crash stack traces and send them to me anonymously. To learn more about that, consider reading Google's own privacy policy.
