Collection of general information

When you access our website, information of a general nature is automatically collected. This information (server log files) includes, for example, the type of web browser, the operating system you are using, the domain name of your Internet service provider and the like. This is exclusively information that does not allow any conclusions to be drawn about your person. This information is technically necessary in order to correctly deliver the contents of web pages requested by you and is absolutely necessary when using the Internet. Anonymous information of this kind is statistically evaluated by us in order to optimise our online presence and the technology behind it.



Like many other websites, we use so-called “cookies”. Cookies are small text files that are transferred from a website server to your hard drive. In this way, we automatically receive certain data, such as your IP address, browser used, operating system about your computer and your connection to the Internet.

Cookies cannot be used to run programs or transfer viruses to a computer. The information contained in cookies allows us to make it easier for you to navigate our site and to enable the correct display of our web pages.

Under no circumstances will the data we collect be passed on to third parties or linked to personal data without your consent.

Of course, you can also view our website without cookies. As a rule, Internet browsers are set to accept cookies. You can deactivate the use of cookies at any time via the settings of your browser. Please use the help functions of your internet browser to learn how to change these settings. Please note that some features of our website may not work if you have disabled the use of cookies.

Use of Google Maps

This website uses Google Maps API to visually display geographic information. When using Google Maps, Google also collects, processes and uses data on the use of the map functions by visitors. Further information on data processing by Google can be found in the Google Privacy Policy. There you can also change your personal data protection settings in the data protection centre.

Embedded YouTube videos

On some of our web pages, we embed Youtube videos. The operator of the corresponding plugins is YouTube, LLC, 901 Cherry Ave, San Bruno, CA 94066, USA. When you visit a page with the YouTube plugin, a connection to the YouTube servers is established. This tells Youtube which pages you are visiting. If you are logged into your Youtube account, Youtube can assign your surfing behaviour to you personally. You can prevent this by logging out of your Youtube account beforehand.

When a Youtube video is started, the provider uses cookies that collect information about user behaviour.

If you have disabled cookies for the Google Ads program, you will not have to deal with such cookies when watching Youtube videos. However, Youtube also stores non-personal usage information in other cookies. If you wish to prevent this, you must block the storage of cookies in your browser.

Further information on data protection at “Youtube” can be found in the provider’s privacy policy at:


Your rights to information, correction, blocking, deletion and objection

You have the right to obtain information about your personal data stored by us at any time. In addition, you have the right to have your personal data corrected, blocked or – apart from the mandatory data storage for business processing – deleted. Please contact our data protection officer for this purpose. You will find the contact details at the bottom of the page.

To ensure that blocking of data can be taken into account at any time, this data must be kept in a blocking file for control purposes. You can also request the deletion of the data unless there is a legal obligation to archive it. If such an obligation exists, we will block your data on request.

You can make changes or withdraw your consent by notifying us with effect for the future.


Change of our data protection regulations

We reserve the right to amend this privacy policy from time to time so that it always complies with the current legal requirements or in order to implement changes to our services in the privacy policy, e.g. when introducing new services. The new privacy policy will then apply to your next visit.

Data processing with the USA

The EU/US Privacy Shield was declared invalid by the ECJ with immediate effect. As far as possible, we now use European service providers and/or servers. Only companies whose standard contractual clauses have been checked for compliance with the level of data protection are eligible for data exchange with the USA.
