We appreciate you visiting our web site and would like to bring to your attention that data will be collected over the course of your visit. From a technical perspective, this cannot be avoided. Protecting your data and the greatest degree of transparency possible are top priorities for us. Here, you can learn what data is collected to what extent and for which purpose in the framework of your use of our internet presence.

Google Analytics.

Our website uses Google Analytics, a Google Inc. (“Google”) web analysis service. Google Analytics uses so-called cookies. Cookies store information about your internet behaviour such as how much time you spend on a website or search terms. Such information is recorded by web servers and saved on your computer (or, more precisely, it is saved in your browser directory). On the basis of this cookie data, Google Analytics analyses your use of our website. For this purpose, the collected information (including your IP address) is transmitted to a Google server in the US and stored there. Google uses this information to analyse the use of our website, generate corresponding reports and provide further services linked to website and Internet usage. Google will also transfer this data to third parties if necessary, provided that this is legally mandated or insofar as third parties have been commissioned by Google to process this data. On no account will Google link your IP address to other data retrieved by Google. Although you can adjust your browser software to prevent the installation of cookies, we would like to point out that if you do so, you may no longer be able to make full use of all the functions on this website.

Through the use of this website, you express your consent to the processing of data collected by Google about you in the
manner described above and for the purpose previously mentioned. You may disagree with the data collection and storage at any time with future effect.

Web server logs.

When you visit our internet site, the server on which our web presence is found (hereafter “web server”) automatically collects and logs specific information from you. This information includes, for example, parts of your IP address, the date, the time, and the data volume transferred during your visit, subpages visited, pages you visited previously, the browser you are using (e.g. Internet Explorer), the operating system you are using (e.g. Windows 7) or the domain name and the address of your internet provider (e.g. 1&1).


Some of the companies associated with the Group use so-called cookie technology on their websites. A cookie is information sent from the web server to your computer (more precisely: filed in your browser directory) as soon as you visit the internet site.

With the exception of the aforementioned manner in the course of web server logs, we will only collect your data when you personally provide it, for example, in order to use the services we offer (e.g. for enquiries). This data will only be processed and/or used for the purpose of realising the respective service. Your data may also be forwarded to Group companies in so far as it is necessary for your enquiry. It may also be necessary for us to hire a service provider to provide the requisite service (e.g. sending out information material). Your personal data will not be transferred to any other third parties.
