When you submit an assignment using Tabula, your identity is stored against the submission. This is required to be able to mark the assignment and return the feedback to you.
We also record various other activities such as when you download your feedback. Some of this event information is made available to your module and department administrators for the sole purpose of running the course more effectively, such as being able to tell how many people are reading their feedback.
If you are using the application as an administrator or educator, your actions within the application are also recorded. This is to provide accountability and assist with diagnosing problems, but the data is not exposed.
