Cookies contain e.g. Information about the user’s previous access to the respective server or information about which offers were previously called.

The permanent cookies ensure that the customer finds his personal settings again when visiting the websites of the responsible office again. For example, we store the used language in a permanent cookie. In addition, the service providers that are integrated in our pages use permanent cookies in order to recognize recurring users. These services store the data transmitted by the cookie only anonymously. An assignment to the IP address of the customer does not take place.
