Android and MS Store Apps
None of our apps on Google Play Store or the Microsoft Store collects any personal data - but for certain education apps (such as Player_) data about your interaction with the app itself is recorded and saved on our web server for a duration of 1 to 3 months. The data is used by your institutes and teachers to analyze how their students are following their courses. For some apps (such as Player_) we also collect certain device identifiers such as device model, and hardware capabilities because these apps are permitted to be run from one device at a time. This data is not used to personally identify you.
