The My EP site needs to store a string of letters and numbers which represent your choices for courses, levels, and what lesson numbers you are on. We do not track any other information. The only other thing we have is whatever you have entered. That would be your email address, any parent add-on course name, and the student names. Typically, those would just be first names. We do NOT store your password. I hope you know that we would NEVER sell your email address.
