Matomo (formerly called Piwik)
This website uses the open source web analysis service Matomo. Matomo uses so-called “cookies,” which are text files that are stored on your computer and that make it possible to analyse your use of this website. In conjunction with this, the information about the use of this website generated by the cookie will be archived on our server. Prior to archiving, the IP address will first be anonymized.

The information generated by cookies concerning the use of this website shall not be shared with any third parties. You may prevent the storage of cookies at any time by making pertinent changes to your browser software settings; however, we have to point out that in this case you may not be able to use all of the functions of this website to their fullest extent.
If you do not consent to the storage and use of your data, you have the option to deactivate the storage and use of such data here. In this case, an opt out cookie will be placed in our browser, which prevent the storage of usage data by Matomo.

Data stored for other purposes with us remain unaffected.
After you unsubscribe from the newsletter distribution list, your e-mail address may be stored by us or the newsletter service provider in a blacklist to prevent future mailings. The data from the blacklist is used only for this purpose and not merged with other data. This serves both your interest and our interest in complying with the legal requirements when sending newsletters (legitimate interest within the meaning of Art. 6 para. 1 lit. f GDPR). The storage in the blacklist is indefinite. You may object to the storage if your interests outweigh our legitimate interest.
8. Plug-ins and Tools
YouTube with expanded data protection integration
Our website embeds videos of the website YouTube. The website operator is Google Ireland Limited (“Google”), Gordon House, Barrow Street, Dublin 4, Ireland.
We use YouTube in the expanded data protection mode. According to YouTube, this mode ensures that YouTube does not store any information about visitors to this website before they watch the video. Nevertheless, this does not necessarily mean that the sharing of data with YouTube partners can be ruled out as a result of the expanded data protection mode. For instance, regardless of whether you are watching a video, YouTube will always establish a connection with the Google DoubleClick network.
As soon as you start to play a YouTube video on this website, a connection to YouTube’s servers will be established. As a result, the YouTube server will be notified, which of our pages you have visited. If you are logged into your YouTube account while you visit our site, you enable YouTube to directly allocate your browsing patterns to your personal profile. You have the option to prevent this by logging out of your YouTube account.
Furthermore, after you have started to play a video, YouTube will be able to place various cookies on your device. With the assistance of these cookies, YouTube will be able to obtain information about our website’s visitors. Among other things, this information will be used to generate video statistics with the aim of improving the user friendliness of the site and to prevent attempts to commit fraud. These cookies will stay on your device until you delete them.
Under certain circumstances, additional data processing transactions may be triggered after you have started to play a YouTube video, which are beyond our control.
The use of YouTube is based on our interest in presenting our online content in an appealing manner. Pursuant to Art. 6 Sect. 1 lit. f GDPR, this is a legitimate interest. If a corresponding agreement has been requested, the processing takes place exclusively on the basis of Art. 6 para. 1 lit. a GDPR; the agreement can be revoked at any time.
Google Web Fonts
To ensure that fonts used on this website are uniform, this website uses so-called Web Fonts provided by Google. When you access a page on our website, your browser will load the required web fonts into your browser cache to correctly display text and fonts.
To do this, the browser you use will have to establish a connection with Google’s servers. As a result, Google will learn that your IP address was used to access this website. The use of Google Web Fonts is based on Art. 6 Sect. 1 lit. f GDPR. The website operator has a legitimate interest in a uniform presentation of the font on the operator’s website. If a respective declaration of consent has been obtained (e.g. consent to the archiving of cookies), the data will be processed exclusively on the basis of Art. 6 Sect. 1 lit. a GDPR. Any such consent may be revoked at any time.
If your browser should not support Web Fonts, a standard font installed on your computer will be used.
For more information on Google Web Fonts, please follow this link: https://developers.google.com/fonts/faq and consult Google’s Data Privacy Declaration under: https://policies.google.com/privacy?hl=en.
Via an API, this website uses the mapping service Google Maps. The provider is Google Ireland Limited (“Google”), Gordon House, Barrow Street, Dublin 4, Ireland.
To enable the use of the Google Maps features, your IP address must be stored. As a rule, this information is transferred to one of Google’s servers in the United States, where it is archived. The operator of this website has no control over the data transfer.
We use Google Maps to present our online content in an appealing manner and to make the locations disclosed on our website easy to find. This constitutes a legitimate interest as defined in Art. 6 Sect. 1 lit. f GDPR.

We use “Google reCAPTCHA” (hereinafter referred to as “reCAPTCHA”) on this website. The provider is Google Ireland Limited (“Google”), Gordon House, Barrow Street, Dublin 4, Ireland.
The purpose of reCAPTCHA is to determine whether data entered on this website (e.g. information entered into a contact form) is being provided by a human user or by an automated program. To determine this, reCAPTCHA analyses the behaviour of the website visitors based on a variety of parameters. This analysis is triggered automatically as soon as the website visitor enters the site. For this analysis, reCAPTCHA evaluates a variety of data (e.g. IP address, time the website visitor spent on the site or cursor movements initiated by the user). The data tracked during such analyses are forwarded to Google.
reCAPTCHA analyses run entirely in the background. Website visitors are not alerted that an analysis is underway.
Data are stored and analyzed on the basis of Art. 6 Sect. 1 lit. f GDPR. The website operator has a legitimate interest in the protection of the operator’s websites against abusive automated spying and against SPAM. If a respective declaration of consent has been obtained (e.g. consent to the archiving of cookies), the data will be processed exclusively on the basis of Art. 6 Sect. 1 lit. a DGDPR. Any such consent may be revoked at any time.
