These cookies ensure that the website visit (which is anonymised as much as possible) can be measured (for example which pages were visited most, which browsers are used by our visitors and what the most frequent screen format is). The service used for this is one of the most widely used web analysis services and is provided by Google Inc. The statistics of the Google Analytics service enable us to improve our website. Google can issue this information to third parties if Google is legally obliged to do so, or if third parties process this information on behalf of Google. We have given permission for Google to use the information obtained for other Google services. The information is transferred to Google and stored on servers in the United States of America. Google states that it abides by the so-called 'Safe Harbor principles' and that it is affiliated to the Safe Harbor programme of the United States Department of Commerce, which means that a suitable level of protection applies to the processing of any personal data.

Tracking cookies register which pages are accessed by a visitor. Based on the pages someone visits, information is stored on the way in which the website is used. Among other things this makes it possible to deduce what the visitor is interested in. The creation of profiles containing such information can then be used for behavioural targeting, in other words the display of advertisements in the form of banners which link up with the area of interest.
