This privacy policy applies to the OxO app available in the Google Play Store.
1) You will be asked to enter your name but this data is stored on your device only and is deleted if you remove the app.
2) The name you enter does not have to be your real name; a pseudonym will do just fine.
3) The app keeps track of how many times you use it and prompts you to rate the app in the Google Play Store after every 100 uses. You can decline to rate it but I'd be very grateful if you tell me what you think about the app.
