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 used, the domain name of your Internet service provider, etc. This is solely information that cannot be used to identify you. This information is technically necessary to enable the content of Websites requested by you and necessarily collected when the Internet is used to be correctly delivered. Anonymous information of this kind is evaluated by us statistically so that we can optimise our Internet site and the technology behind it.


Like many other Websites, we also use cookies. Cookies are small text files that are transferred from a Website server to your hard disk. By this means we automatically receive via your computer and your connection to the Internet certain data, such as IP address, browser used and operating system.
Cookies cannot be used to start programs or transmit viruses to a computer. Information contained in cookies enables us to make navigation easier for you and to enable our Websites to be correctly displayed.

Data collected by us will never be disclosed to third parties or linked to personal data without your permission.

You can of course also look at our Website without cookies. Internet browsers are regularly set to accept cookies. You can disable the use of cookies at any time through your browser settings. Please use the help function on your Internet browser to find out how to change these settings. Please note that individual functions of our Website may not function if you have disabled the use of cookies.

SSL Encryption

To ensure the security of your data during transmission, we use state-of-the-art encryption techniques (e.g. SSL) via HTTPS.

Contact Form

If you contact us by email or contact form, the data provided by you will be stored to enable us to process your enquiry and any possible follow-up enquiries.

Erasure and Blockage of Data

We abide by the principles of data avoidance and data economy. We store your personal data only for so long as is necessary to achieve the purposes stated here or as provided for by the many and varied storage periods laid down by legislation. After the purpose has ceased to apply or these periods have expired, the data concerned will be blocked or erased routinely and as required by law.

Analyze-/Tracking-Tool: Matomo

We use Cookies for the Analysis-/Tracking-Tool „Matomo“ (formerly known as Piwik). This data process is based on (point f) of Art. 6 (1) GDPR: Our legitimate interests for this date process: With the tracking-tool „Matomo“ we want to optimize our website and usability of our website. Also, we use „Matomo“ to evaluate the use of our website statistically and to optimize our website for our users.

„Matomo“ is an open source web analysis-software. Anonymized user profiles are created and Cookies (s. fig. 4) are stored. The IP-address will be anonymized (IP-masking). This means we store through Matomo in the database each new visitor IP address (ipv4 or ipv6 format) with the last components removed to protect the website user’s privacy.

In the Cookies Matomo uses the following information is stored:

  • anonymized IP-address/pseudonymized User-ID,

  • browsertype/-version,

  • used operating system,

  • referrer-URL (website visited before our website),

  • date and time of the server-request,

  • title of the page being viewed (Page Title),

  • URL of the page being viewed (Page URL),

  • URL of the page that was viewed prior to the current page (Referrer URL),

  • screen resolution being used,

  • time in local user’s timezone,

  • pages generation time (the time it takes for webpages to be generated by the webserver and then downloaded by the user),

  • location of the user: country, region, city, approximate latitude and longitude,

  • main language of the browser being used.

The information is sent to and stored by our data processor (web host in Germany). The information is then used to evaluate the use of the website, to generate a report about the website-activities and to analyze the use of the website-services related to market research and demand-driven design of the website. The information might only be submitted to third parties to the extent that legal obligations have to be met or a data processor (like a web host) is commissioned.

However, you can configure your browser so it does not store any Cookies on your device/browser or you are asked before any Cookie is stored. If you activate the “Do-Not Track”-option in your browser, we do not use the Matomo Cookies. We would like to point out that some functions of the website may not work properly or at all if you deactivate Cookies in your browser.

As an alternative to the browser add-on, especially for browsers on mobile devices, you can also prevent the collection by Matomo by not checking the "Statisics" box in the cookie banner when you first visit the website and clicking on "Save and close" or by not editing the cookie banner. Cookies are only set when you check the box "Statistics".

If you do not check the "Statistics" box, an opt-out cookie will be set to prevent the future collection of your data when you visit this website. However, the opt-out cookie is only valid in the browser used at the time of activation and only for our website and is stored on your device. If you delete the cookies in this browser, you must set the opt-out cookie again.


Use of Script Libraries (Google Webfonts)

To present our content correctly and graphically appealingly across different browsers, we use script libraries and font libraries such as Google Webfonts ( on this Website. Google web fonts are transferred to the cache of your browser to prevent multiple loading. If the browser does not support Google Web fonts or prohibits access, the content will be displayed in a standard font.

The display of script libraries or font libraries automatically triggers a connection to the operator of the library. It is theoretically possible - but currently also unclear whether and if so for what purposes - that operators of such libraries collect data.

The library operator Google's protection policy can be found at:


Use of Google Maps

This website uses Google Maps to visually display geographic information. When Google Maps are used, Google also collects, processes and uses data about the use of map features by visitors. For more detailed information about Google's data processing, please refer to the Google Privacy Notice. There you can also change your personal protection settings in the protection center.

Detailed information about management of your own data in connection with Google products can be found here.

Embedded YouTube Videos

We embed YouTube videos on some of our Websites. The operator of the relevant plug-ins is YouTube, LLC, 901 Cherry Ave., San Bruno, CA 94066, USA. When you visit a site with the YouTube plug-in, a connection is made to YouTube servers. YouTube is then informed about the sites you are visiting. If you are logged in to your YouTube account, YouTube can match your surfing habits to your personal profile. You can prevent this by logging out of your YouTube account beforehand.

If a YouTube video is started, the provider uses cookies to gather information about user habits.

If you have disabled the storage of cookies for the Google Ad program, you do not have to reckon with cookies of this kind when viewing YouTube videos.

However, YouTube also files non-personal use information in other cookies. If you want to prevent this, you must disable storage of cookies in the browser.
