What personally identifiable information is collected on students and how it's used?

Microsoft Store limits the data that can be stored by the apps. We do collect IP address, device model, user location, geo, and demographical data, login time, and the usage of some features of the app. At the same time, the data we collect is general and doesn’t link to any particular user. We do not store emails, except for the one used by your school during registration, names, and other sensitive personal data. You can read more here.   

How is it used?

We use the statistical data only internally, in order to improve the app functionality, decide what features are useful for users, and what are not.
