Usage analysis on our website

Google Analytics

This website uses Google Analytics, a web-analytics service provided by Google Inc. („Google”).

Google Analytics, too, uses „cookies”. The information generated by the cookie about your use of this website will generally be transmitted to and stored by Google on servers located in the United States. This website uses Google Analytics with the extension „_anonymizeIp()“. In this way, Google in advance truncates IP addresses within member states of the European Union or other signatory states to the Agreement on the European Economic Area. Any direct reference back to a person within the scope of further processing can thus be excluded. Only in exceptional cases is the full IP address transmitted to a Google server in the US and truncated there. On behalf of the operator of this website, Google uses this information to evaluate your use of the website, to compile reports on website activity and to provide other services relating to website activity and internet usage to the website operator. The IP address transmitted by your browser as part of Google Analytics is not combined with other Google data.

You may prevent the storage of cookies by selecting the appropriate settings in your browser; please note, however, that if you do this you may not be able to use the full functionality of this website. 

In addition, you can prevent the capture of your data generated by the cookie and relating to the use of the website (incl your IP address) for Google and the processing of such data by Google by downloading and installing the browser plugin available under the following link:

Google Maps

This website uses Google Maps to display maps and to create route maps. Google Maps is operated by Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA. If you use Google's advanced features, such as clicking on the map that appears, you are using a Google service outside of our control. In this case, the stipulations and remarks provided by Google in this context apply.

On our website available at, you can find more information about Google's terms of use („General Terms of Service“), additional terms of use for Google Maps/Google Earth („Additional Terms of Service for Google Maps/Google Earth“), legal notices for Google Maps/Google Earth („Legal Notices“) and Google's privacy policy („Privacy Policy“). In Google's Privacy Policy [], you will find information about which data records are collected for which purpose and what Google does with the data.

Online presence on social media

We maintain online presences within social networks and platforms so that we can communicate with our customers active there, and inform them about our services. We would like to point out that user data may be processed outside the European Union. This may entail risks for users, eg by making it more difficult to enforce users' rights. With regard to US providers that are certified under the Privacy Shield, we would like to point out that they then commit themselves to comply with EU data-privacy standards.

In addition, user data are normally processed for market-research and advertising purposes. For example, on the basis of user behaviour and the user interests identified, user profiles can be created. Such user profiles, in turn, can be deployed, eg, to place advertisements inside and outside the platforms presumed to correspond to the interests of the users. For these purposes, cookies are normally stored on the user's computer recording use behaviour and interests. Furthermore, data can be stored in the user profiles independently of the devices deployed by the users (especially if the users are members of the various platforms and are logged in to them).
The processing of users' personal data is on the basis of our legitimate interests in the effective information of users and communication with users in accordance with sec. 6(1), letter f. of General Data Protection Regulation (GDPR). If users are asked by the providers concerned for their consent to data processing (ie declare their consent, eg by ticking a checkbox or confirming a button), the legal basis for processing is sec. 6(1), letter a., sec. 7 GDPR. For a detailed description of the various processing possibilities and opt-outs, we refer to the following linked information of the providers. Also in the case of requests for information and the assertion of user rights, we wish to point out that these can be asserted most effectively with the providers. Only the providers have access to the data of their users and can directly take appropriate measures and provide information. If you need help nevertheless, please do not hesitate to contact us.

Usage of Facebook social plugins

On the basis of our legitimate interests (ie interest in the analysis, optimization and economic operation of our online offering in the sense of sec. 6(1), letter f. GDPR), we make use of the social plugins („Plugins“) of the social network, which is operated by Facebook Ireland Ltd., 4 Grand Canal Square, Grand Canal Harbour, Dublin 2, Ireland („Facebook“). The plugins can display interaction elements or content (eg videos, graphics or text contributions) and are made recognizable by one of Facebook's logos (white „f“ on a blue tile, the terms „Like“, or a „Thumbs up“ sign) or are marked with the addition „Facebook Social Plugin“. The list and appearance of Facebook's social plugins can be viewed here: .

Facebook is certified under the Privacy Shield agreement, guaranteeing adherence to Europe's data-protection law ( . When a user invokes a function of this online service that contains such a plugin, his device establishes a direct connection with Facebook's servers. The content of the plugin is transmitted directly from Facebook to the user's device and integrated into the online offering by the device. Here, user profiles can be created from the processed user data. We therefore have no influence over the extent of the data that Facebook collects using this plugin and then, to our knowledge, informs users.

From the integration of the plugins, Facebook is informed that a user has called the page concerned in the online offering. If a user is logged in to Facebook, Facebook can assign the visit to his Facebook account. When users interact with the plugins, eg by clicking the Like button or commenting, the corresponding information is transmitted from their device directly to Facebook and stored there. If a user is not a member of Facebook, it is still possible for Facebook to know and store his IP address. According to Facebook, only an anonymized IP address is stored in Germany.

The purpose and scope of the data collection and the further processing and use of the data by Facebook as well as the related rights and setting options to protect the privacy of users, can be found in Facebook's privacy policy: . If a user is a Facebook member and does not wish Facebook to collect data about him via this online service and link them to his Facebook member data, he must log out of Facebook and delete his cookies before using our online service.

Further settings and opt-outs on the usage of data for advertising purposes are possible within Facebook's profile settings: or via the US page or the EU page .
The settings are platform-independent, ie they are adopted for all devices, like desktop computers or mobile devices.


Within our online offering, functions and content of the service Instagram, offered by Instagram Inc., 1601 Willow Road, Menlo Park, CA, 94025, USA, can be integrated. This may include, for example, content such as images, videos or text and buttons with which users can express their liking of such content, the authors of the content or subscribe to our contributions. If users are members of the Instagram platform, Instagram can assign the call-up of the above content and functions to the profiles of the users there. Data-privacy policy of Instagram: .


We integrate the videos of the „YouTube“ platform offered by the provider Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA. Data-privacy policy:
