Saving is optional. Only skill test names, dates and topic scores are saved in this browser until their 30-day expiry when you choose Save this skill result. Expired entries are removed the next time this dashboard or a skills result is opened. Answers and reflection profiles are not saved here. There is no account or server dashboard.
