No data is collected directly by the app. Google Play does provide us with analytics and crash reports, but they've got their own policies for that.
Because nothing's transmitted to us from the app, we're obviously not sharing anything with anyone.
That said, this might change in the future (e.g., if we add additional analytics, ads, and probably anything else that actually requires an internet connection). So if the policy changes, we'll post the latest one here. To stay informed of any of those changes, it's suggested you bookmark this page and visit it often.
