There are cookies that are deleted when you close your browser (transient cookies) as well as cookies that are stored on your computer for a specific period of time, which can differ from cookie to cookie (persistent cookies). A common type of transient cookies are session cookies, which store a so-called session ID that enables various requests from your browser to be assigned to a common session. That allows your computer to be recognised when you return to our websites. Session cookies are deleted when you log out or close your browser. You can delete persistent cookies at any time using your browser’s security settings.

  • if we process your personal data for purposes of direct marketing; or
