Google Analytics

This website uses Google Analytics, a web analysis service of Google Inc, (1600 Amphitheatre Parkway Mountain View, CA 94043, USA; "Google"). The use includes the "Universal Analytics" operating mode. This facilitates the assignment of data, sessions and interactions across several devices to a pseudonymous user ID and thus the analysis of a user's activities across devices.

Google Analytics uses "cookies", which are text files placed on your computer, to allow the website operator to analyze how users use the site. The information generated by the cookie about your use of this website is usually transferred to a Google server in the USA and stored there. However, if IP anonymisation is activated on this website, Google will reduce your IP address within Member States of the European Union or in other states party to the Agreement on the European Economic Area beforehand. Only in exceptional cases will the full IP address be transmitted to a Google server in the USA and shortened there. The IP address transmitted by your browser in the context of Google Analytics is not merged with other Google data. On behalf of the operator of this website, Google will use this information to evaluate your use of the website, to compile reports on website activity and to provide the website operator with other services related to website and Internet use. Our legitimate interest in data processing also lies in these purposes. The legal basis for the use of Google Analytics is § 15 para. 3 TMG and Art. 6 para. 1 lit. f GDPR. The data sent by us and linked to cookies, user-identifiers (e.g. User-IDs) or advertising-identifiers are automatically deleted after 14 months. Data whose retention period has been reached is automatically deleted once a month. For more information on terms of use and data protection, please visit or

Browser add-on for disabling Google Analytics and opt-out cookie

To give website visitors more control over how their data is collected via Universal Analytics, Google has developed a Universal Analytics deactivation add-on for browsers. The add-on communicates with the Google Analytics JavaScript (analytics.js) to indicate that information about your visit to the website should not be sent to Google Analytics. The deactivation add-on for browsers does not prevent information from being sent to the website itself. 

Please click here to find out more about the Google Analytics deactivation add-on for browsers.

Alternatively, you can set a cookie to prevent collection of data by Universal Analytics. Click here to set the opt-out cookie.
