We are providing a Moodle Instance for better coordination of our lectures, to provide information and a platform for discussion, and for interactive exercises. We ask every student, who is participating in our lectures, to use the learning platform for a better learning experience.
The account used to login is already handled by LDAP or is out of our range (because we are utilizing the HPI user account backend) and we use cookie-based authentication (see the section about non-public websites).
Account deletions can be requested by mail (like the sections above).
We are storing activity logs for logged-in users to retrace unwanted or malicious behaviour. They get deleted after 10 days and no automated analysis will happen to them.
To provide the full functionality it is necessary to store user-owned and user-connected data (always bound to a lecture/course), e.g. submissions or forum discussions, or gradings. They get deleted when the course is deleted.
Somehow, not all user-owned data can be deleted while a lecture is still running, because forum discussions could get incomprehensible or exercise sheets might still be needed for grading completion. Some data might even be needed until the whole grading process is completed, because the Moodle is used as documentation source for reached grading points. Though it is technically possible to remove such data, it might not always be allowed due to the strong integration into the lectures.
Anyhow, most data directly resulting from account actions can safely be deleted.
Illegal content (including copyright infringements) will be manually removed, at least after we got to know it.
For some data (surveys, exercise submissions, forum questions, gradings,...) it is necessary to be processed. Some analysis happens automatically, e.g. summation of grading points to form a grade or the evaluation of a survey. In other cases the processing is done by lecturers and their (student) assistants. They are required to respect the users privacy, but their processing is a requirement for the lecture too. For their complete rights regarding grading, please see your study regulations.
As an alternative to our platform we can only offer you a minimum of the requirements for our lectures (like exercise submission) to happen by mail or file share. Otherwise it is technically not possible or hard to implement. We welcome suggestions, if necessary.
