We furthermore use the anonymous information for statistical purposes. They help us optimize the offers and technology.

Receiving the newsletter requires a valid e-mail address. The IP address from which you sign up for the newsletter and the date on which you order the newsletter will also be stored. These data serve as proof for us in case of abuse if a different e-mail address is registered for the newsletter. According to legal requirements, we are working with the so-called “double opt-in” method for additionally making sure an e-mail address is not abusively entered into our distribution list by third parties. In the course of this method, ordering the newsletter, sending the confirmation e-mail and receipt of the registration conformation are journalized.

Integration of services and contents of third parties

Our offer sometimes includes contents, services and performances of other providers. These are, for instance, maps made available by Google Maps, videos from YouTube as well as images and pictures from other web sites. Submitting the IP address is by all means necessary for accessing and presenting these data in the browser of the user. The providers (called “third party providers” in the following) will thus note the IP address of the corresponding user.

Even though we are trying to use exclusively third party providers which require the IP address only for being able to supply contents, we do not have any influence on whether the IP address is possibly stored. In this case, this process serves for statistical purposes, among others. In case we know the IP address is being stored we will inform our users about this.
