I personally don't collect any data whatsoever, but in order for the app to function well, some of your data is being used.
That concerns first of all the ads which are handeled by unity, whose privacy policy you can access here.
To access the leaderboard and sync your progress, Google is also collecting some data. You can always disable this function in the settings.
Feel free to contact me if you need any help at contact.pitchgames@gmail.com!
Have fun!
