The app does use some Android services to simplify data entry if available on your device and Google publishes its own services policy here:
In case of an error in the application Google Play collects log data related to the crash and makes it available to us to help solve the problem. Log data is used solely to determine what caused the crash so that we can fix the problem, and for no other purpose.
Links to Other Sites
The application contains no links to third party sites.
The application is written for licensed pilots and as such targets only adults. In any case since no information is sent to us for anyone of any age by the application, users of all ages are protected.
This policy is effective as of Jan 1, 2022.
