Harmonomics Privacy Policy Harmonomics does not collect any personal information. Performance on the exercises (correct answers, attempts, time per question, etc) is collected and stored on the device. If you import an exercise from another user, if that user has opted to collect performance data, your performance will be stored on a server and the results shown to just the creator of the exercise. Your performance will be labled with your "identifier" which is by default a randomly-created anonymous string of characters. In the Settings screen of Harmonomics, you can choose a different identifier for yourself. The stored statistics can be deleted at any time from the Settings screen of the application.
