My courses use AI teaching assistants. To keep track of individual performance and learning outcomes, the teaching assistant keeps track of the users's email address and might also store a cookie to allow keeping state across multiple interaction sessions.
All information collected on behalf of any user will be solely used for the purposes of that course and that specific user - in terms of feedback, grades etc. There is no intention to share this information with anyone else other than the user and best efforts will be made for the same.
