Your information is private. It will not be shared with anyone in an identifiable way, and we have taken security measures to ensure that nobody except you can access the information.
Information you provide will contribute to anonymous, aggregate data that we use to improve the validity of the tests and better understand how the human brain works. For example, we may look at the average Double Trouble score for everybody who got less than 7 hours of sleep. Your score and sleep data would only contribute a tiny amount to that average, and would not be associated with you in any way.
