The temporary logging of these cookies can be disabled by changing the appropriate settings of the internet browser. This does not affect the access or use of the page, but disabling cookies may increase the server’s response time slightly.

Blocking these cookies can impair access to and utilisation of the website. The authentication process is only relevant for administrators of this portal. Visitors of this portal will not be involved in an authentication process and will only access the portal content as a guest.

  • the page visited
  • the referrer website that the user accessed before visiting the university website
  • the sub-pages accessed
  • the duration of the visit
  • how often the user accesses the web page
  • browser
  • browser recognition
  • resolution

The software runs exclusively on our servers. User data is only saved to our servers. It is not passed on to third parties.
