On privacy policy for all apps.

It’s very simple. We gather

• Aggregated behavior data:
  • what pages do our users visit most
  • what pages do our users visit least
• user data:
  • data needed for the application to work
  • examples: test scores, high scores, etc

None of the user data is shared with others without your prior consent.

The aggregated behavior data is gathered by Google Analytics, and this is done in an anonymous way.
