Purposes of data processing by the body responsible and by third parties

We process your personal data only for the purposes stated in this data protection declaration. No transfer of your personal data to third parties for purposes other than those mentioned takes place. We will only pass on your personal data to third parties if:

•    You have given us your express consent
•    the processing is necessary to implement a contract concluded with you,
•    the processing is necessary to meet a legal obligation,
•    the processing is necessary to safeguard legitimate interests and if there is no reason to assume that you have an overriding legitimate interest in not disclosing your data.

Deletion or blocking of data

We adhere to the principles of data avoidance and data economy. We therefore only store your personal data for as long as necessary to achieve the purposes mentioned here or as stipulated by the various storage periods provided by law. After discontinuation of the respective purpose or expiry of these deadlines, the corresponding data will be routinely blocked or deleted in accordance with the statutory provisions.

Collection of general information when you visit our website

When you access our website, information of a general nature is automatically recorded using a cookie. This information (server log files) includes, for instance, the kind of web browser, the operating system used, the domain name of your internet-service provider and the like. All these pieces of information do not allow any conclusions to be drawn about your person.

Collecting this information is technically necessary in order to correctly deliver the website content you have requested and it is mandatory when using the internet. In particular, it is processed for the following purposes:

•    Ensuring a trouble-free connection to the website,
•    Ensuring the smooth use of our website,
•    Evaluation of the system security and stability as well as
•    further administrative purposes.

The processing of your personal data is based on our legitimate interest in the aforementioned data-collection purposes. We do not use your data to draw conclusions about you personally. The recipient of the data is only the responsible body and, if necessary, the commissioned data-processor.

Anonymous information of this kind may be statistically evaluated by us in order to optimise our website and the technology behind it.


Like many other websites, we also use so-called “cookies”. Cookies are small text files that are transferred to your hard drive by a website server. Through this, we automatically retrieve certain data such as your IP address, the browser used, the operating system and your internet-service renderer.

Cookies cannot be used to start programmes or transfer viruses to a computer. By using the information contained in cookies, we can make navigation easier for you and ensure that our website is displayed correctly.

In no case will the data collected by us be passed on to third parties nor will they be associated with your personal data without your consent.

In general, you can, of course, also view our website without cookies. Internet browsers are regularly set in such a way that they routinely accept cookies. In principle, you can always deactivate the use of cookies at any time via the settings of your browser. Please use the help functions of your internet browser to find out how you can change these settings. Please note that individual functions of our website may no longer work properly if you have deactivated the use of cookies.

SSL encryption

In order to protect the security of your data during transmission, we use state-of-the-art encryption methods (e.g. SSL) over HTTPS.

Use of Matomo

This website uses Matomo (formerly Piwik), an open-source software for the statistical analysis of visitor access. Matomo uses so-called cookies, i.e. text files that are saved on your computer and that allow us to analyse your use of our website.

The information generated by the cookie about your use of our website is then stored on a server in France.

The IP address is anonymised immediately after processing and before the processed data are saved. You have got the option of preventing the installation of cookies by changing the settings of your browser software. We herewith would like to point out that if the settings are configured accordingly, not all functions of this website may be available.

You can decide whether or not an explicit web-analysis cookie can be saved in your browser in order to enable the website operator to collect and analyse various statistical data.

Use of script libraries (for instanceGoogle Webfonts)

In order to present our content correctly and in a graphically appealing way on all kinds of browsers, we use script libraries and font libraries such as for instance Google Webfonts ( The diverse Google Webfonts are transferred to the cache of your browser to avoid multiple downloading. If the browser does not support Google Webfonts or prevents access, the content is displayed in a standard font.

The download of script libraries or font libraries automatically triggers a connection to the operator of the respective library. It is theoretically possible – but currently also unclear whether and, if at all, for what purposes – that operators of such libraries collect data.

You can find the privacy policy of the library operator Google here:

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 about the use of the map functions by visitors. You can find more information about data processing as done by Google in the Google data-protection information passage. There, you can also change your personal data-protection settings in the data-protection centre.

Please find detailed instructions on the management of your own data in connection with Google products here.

Embedded YouTube Videos

We embed YouTube videos on some of our websites. The operator of the corresponding plug-ins is YouTube, LLC, 901 Cherry Ave., San Bruno, CA 94066, USA. When you visit a page with the YouTube plug-in, a connection to YouTube servers is established. In doing so, YouTube is informed about what pages you visit. If you are logged in to your YouTube account, YouTube can allot your surfing behaviour to you personally. You can prevent this by logging out of your YouTube account beforehand.

Whenever a YouTube video is started, the provider uses cookies that collect information about your user behaviour.

If you have deactivated the saving of cookies for the Google ad programme, you will not have to worry about such cookies when watching YouTube videos. However, YouTube also saves non-personal usage information in other cookies. If you want to prevent this, you have to block the saving of cookies in your browser.

More information on data protection provided by “Youtube” can be found in the provider's data-protection declaration under:

Possible changes to our data-protection regulations

We reserve us the right to adapt this data-protection declaration so that it always complies with current legal requirements or in order to implement changes to our services in the data-protection declaration, e.g. when introducing new services. The new data-protection declaration will then apply to your next visit.
