If you use this website, various pieces of personal data will be collected. Personal information is any data with which you could be personally identified. This privacy policy explains what information we collect and what we use it for. It also explains how and for what purpose this is done. Please note that data transmitted via the internet (e.g. via e-mail communication) may be subject to security breaches. Completely protecting data against third-party access is impossible.

DThe controller responsible for processing the data on this website is:

Many data processing operations are only possible with your express consent. You may revoke your consent at any time. An informal message sent to us by e-mail is sufficient. The legality of the data processing performed prior to the revocation remains unaffected by the revocation.

If there has been a breach of data protection legislation, the person affected may file a complaint with the competent regulatory authorities.

If you request the direct transfer of data to another data controller, this shall only take place to the extent that is technically feasible.

SSL or TLS encryption
This site uses SSL or TLS encryption for security reasons and for the protection of the transmission of confidential content, such as the enquiries you send to us as site operator. You can recognise an encrypted connection by the fact that the address line of the browser changes from “http://” to “https://”, and the lock symbol in your browser bar.
If SSL or TLS encryption is activated, the data you transfer to us cannot be read by third parties.

As permitted by law, you have the right to be provided with information free of charge at any time about any of your personal data that is stored as well as its origin, the recipient and the purpose for which it has been processed. You also have the right to have this data corrected, blocked or deleted. You can contact us at any time using the address given in our legal notice if you have further questions on the topic of personal data.

We hereby expressly prohibit the use of contact data published in the context of website legal notice requirements with regard to sending promotional and informational material not expressly requested. The website operator expressly reserves the right to take legal action in the event that unsolicited marketing material is received, for example spam emails.


Some of our webpages use cookies. Cookies do not damage your computer and do not contain viruses. Cookies help to make our website more user-friendly, efficient and secure. Cookies are small text files that are stored on your computer and saved by your browser.

Most of the cookies we use are “session cookies”. They are automatically deleted after your visit. Other cookies remain in your device’s memory until you delete them. These cookies make it possible to recognise your browser when you next visit the site. You can configure your browser in a way so to get informed whenever a cookie is set, and you can choose on a case-by-case basis whether or not to allow this. You can also set up your browser to prohibit the setting of cookies in general, and/or to delete cookies automatically when you close the browser. Disabling cookies may limit the functionality of this website.

Cookies which are necessary to carry out the electronic communication process, or to provide certain functions desired by you (e.g. shopping basket function), are stored on the basis of Art. 6 para. 1(f) GDPR. The website owner has a legitimate interest in storing cookies for the correct technical and optimised delivery of its services. If other cookies (such as those used to analyse your surfing behaviour) are also stored, they will be treated separately in this Privacy Policy.

Server log files
The website provider automatically collects and stores information in “server log files”, which your browser automatically transmits to us. These are:

  • Browser type and browser version
  • The operating system used
  • Referrer URL
  • Host name of the accessing computer
  • Time of the server request
  • IP address

This data will not be combined with data from other sources. The basis for data processing is Art. 6 para. 1 lit. b DSGVO, which permits the processing of data for the fulfilment of a contract or pre-contractual measures.


Should you send us questions via the contact form, we will collect the data entered on the form, including the contact details you provide, in order to answer your question and any follow-up questions. We do not share this data without your permission. Thus, the data entered in the contact form will only be processed given your consent (Art. 6 para. 1 (a) GDPR). You may revoke your consent at any time. An informal message sent to us by e-mail is sufficient. The legality of the processing of data which has already occurred before we receive your request remains unaffected by this.

We will retain the data you provide on the contact form until such time as you request its deletion, revoke your consent for its storage, or the purpose for its storage no longer applies (e.g. after fulfilling your request). Any mandatory statutory provisions – especially those regarding mandatory data retention periods – remain unaffected by this provision.


This website uses Google Analytics, a web analysis service. This is operated by Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA.

Google Analytics uses so-called “cookies”. These are text files that are stored on your computer and that allow an analysis of your use of the website. The information generated by the cookie about your use of the website is usually transmitted to and stored by Google on servers in the United States. Google Analytics cookies are stored on the basis of Art. 6 para. 1 lit. f GDPR. The website operator has a legitimate interest in analysing user behaviour in order to optimise both its website and its advertising.

This website uses Google AdWords. AdWords is an online advertising programme from Google Inc., 1600 Amphitheater Parkway, Mountain View, CA 94043, United States (“Google”).

As part of Google AdWords, we use so-called conversion tracking. When you click on an ad served by Google, a conversion tracking cookie is set. Cookies are small text files that the internet browser stores on the user’s computer. These cookies expire after 30 days and are not used for personal identification of the user. If you visit certain pages of the website and the cookie has not yet expired, Google and the website can tell that you clicked on the ad and proceeded to that page.

Each Google AdWords customer receives a different cookie. Thus, cookies cannot be tracked using the website of an Adwords advertiser. The information obtained using the conversion cookie is used to create conversion statistics for Adwords customers who have opted into conversion tracking. Customers are told the total number of users who clicked on their ad and were redirected to a conversion tracking tag page. However, they do not obtain any information which can be used to identify you personally. If you do not wish to participate in tracking, you can refuse by simply deactivating the Google conversion tracking cookie via your internet browser settings. By doing so, you will not be included in the conversion tracking statistics.

“Conversion cookies” are stored on the basis of Art. 6 para. 1 lit. f GDPR. The website operator has a legitimate interest in analysing user behaviour in order to optimise both its website and its advertising. For more information about Google AdSense and Google conversion tracking, please see Google’s privacy policy at

You can configure your browser in a way so to get informed whenever a cookie is set, and you can choose on a case-by-case basis whether or not to allow this. You can also set up your browser to prohibit the setting of cookies in general, and/or to delete cookies automatically when you close the browser. Disabling cookies may limit the functionality of this website.


The data controller has integrated components from Facebook on this website. Facebook is a social network.

A social network is an Internet-based social meeting place, an online community that usually enables users to communicate with each other and interact in virtual space. A social network can serve as a platform for exchanging opinions and experiences or enables the Internet community to provide personal or company-related information. Facebook enables users of the social network to create private profiles, upload photos and network via friendship requests, among other things.

The operating company of Facebook is Facebook, Inc., 1 Hacker Way, Menlo Park, CA 94025, USA. The entity responsible for the processing of personal data, if the entity in question resides outside the US or Canada, is Facebook Ireland Ltd., 4 Grand Canal Square, Grand Canal Harbour, Dublin 2, Ireland.

On each visit to one of the individual pages of this website, which is operated by the data controller and which has integrated a Facebook component (Facebook plug-in), the relevant Facebook component causes the Internet browser on the information technology system of the data subject to automatically download from Facebook a representation of the corresponding Facebook component. An overview of all Facebook plug-ins can be found at As part of this technical process, Facebook receives information about the specific sub-page of our website visited by the data subject.

If the data subject is simultaneously logged in to Facebook, Facebook recognises which specific sub-page of our website they visited for each visit to our website and during the entire duration of the respective visit to our website. This information is collected through the Facebook component and assigned by Facebook to the appropriate Facebook account of the data subject. If the data subject clicks one of the Facebook buttons integrated on our website, for example the “Like” button, or they make a comment, Facebook assigns this information to the personal Facebook user account of the data subject and stores this personal data.

Facebook receives information via the Facebook component that the data subject has visited our website whenever they are logged in to Facebook at the same time as accessing our website; this happens regardless of whether the data subject clicks on the Facebook component or not. If the data subject does not want this information to be transmitted to Facebook, he/she can prevent it from being transmitted by logging out of his/her Facebook account before accessing our website.

The data policy published by Facebook, available at, provides information on the collection, processing and use of personal data by Facebook. It also explains what setting options Facebook offers to protect the privacy of the data subject. In addition, various applications are available that make it possible to suppress data transmission to Facebook. Such applications can be used by the data subject to suppress the transfer of data to Facebook.

Privacy Policy for the Use of YouTube

Our website uses plug-ins from the YouTube site, which is operated by Google. The website operator is YouTube LLC, 901 Cherry Ave., San Bruno, CA 94066, USA. If you visit one of our pages featuring a YouTube plug-in, a connection to the YouTube servers is established. Here the YouTube server is informed about which of our pages you have visited.

If you’re logged in to your YouTube account, YouTube allows you to associate your browsing behaviour directly with your personal profile. You can prevent this by logging out of your YouTube account.

This website uses so-called web fonts provided by Google to support the uniform display of fonts. When you open a page, your browser loads the required web fonts into your browser cache in order to display texts and fonts correctly. To do this, the browser you use must connect to Google’s servers. Google is therefore aware that our web page was accessed via your IP address. Google Web fonts are used in the interest of a uniform and appealing presentation of our website. This represents a legitimate interest within the meaning of Art. 6 para. 1 (f) GDPR. If your browser does not support web fonts, a standard font will be applied by your computer instead.
