General data protection declaration
The protection of your personal data is very important to us. Therefore, your personal data will always be treated confidentially and always in accordance with the current legal data protection regulations. By visiting our website, you agree to the collection, processing and use of data in accordance with the following description.

Collection of access data and log files when visiting our website
Based on our legitimate interests (ensuring the smooth operation of the website), we collect data on accesses to the server on which our website is located (so-called server log files). Information such as the name of the website accessed, file, date and time of access, amount of data transferred, notification of successful access, browser type (incl. version), the user's operating system, referrer URL (the previously visited page), IP address and the requesting provider is stored in these log files. Log file information is collected for security reasons (e.g. to clarify acts of abuse or fraud) and stored for as long as is necessary for evidentiary purposes. This is anonymous data which is only used by us to optimise our website and thus provide our customers with a better online experience.

References and links
We do not accept any liability for direct or indirect references to external websites (via so-called hyperlinks) which lie outside our area of responsibility. We hereby expressly declare that at the time the links were created, no illegal content was identifiable on the linked pages. We have no influence on the current and future design, content or authorship of the linked pages. Therefore, we hereby expressly distance ourselves from all contents of all linked/connected pages that were changed after we set the links. The provider of the linked page alone is liable for illegal, incorrect or incomplete content and in particular for damages arising from the use or non-use of such information.

Dealing with personal data
Personal data means all information that relates to a specific or identifiable person. A data subject is a person about whom personal data is processed.

Your data will not be passed on to third parties - apart from the above-mentioned purposes.

In addition, we will retain your information for such additional period as may be permitted or necessary to, among other things, comply with our legal obligations, resolve disputes and enforce agreements. We will delete your data wherever and whenever required by applicable law.

If you have any questions or concerns about our privacy policy or your personal data, please do not hesitate to contact us. You can do so by emailing us at

Cookie usage
We use cookies on our website to measure information about the use and reach of our website. This is done on the basis of a legitimate interest (optimising our online offering and the associated user experience). Cookies are small text files that are stored on your computer and enable an analysis of your use of the website. This gives us the opportunity to make our offer more customer-friendly. Cookies remain stored beyond the end of a browser session and can be retrieved when you visit the site again. You can deactivate the use of cookies on our website and/or third-party providers at any time in your browser settings or allow/block them individually. Please note that deactivating cookies may mean that you can no longer use certain functions of our (and other) sites to the same extent.

SSL Encryption
This site uses SSL encryption for security reasons and to protect the transmission of confidential content, such as enquiries that 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 by the lock symbol in your browser line. If SSL encryption is activated, the data you transmit to us cannot be read by third parties.

If you would like to receive the newsletter offered on the website, we require an e-mail address from you as well as information that allows us to verify that you are the owner of the e-mail address provided. Further data will not be collected. We use this data exclusively for sending the requested information and do not pass it on to third parties. You can revoke your consent to the storage of the data, the e-mail address and their use for sending the newsletter at any time by unsubscribing from our mailing list.

Use of Google Tag Manager
Within our website, we use the Google Tag Manager of the company Google Inc. In the European area, the company "Google Ireland Limited" based in Ireland is responsible for this. With the help of the Google Tag Manager, we manage various code snippets of different tracking tools. These code snippets are referred to as "tags" in technical jargon. Mostly they come from Google products like Google Ads, GA4 but also social media tags (like Pinterest and Facebook) can be managed within the Tag Manager. These then collect browser data, set cookies or can track users across websites. We use the Tag Manager in our company to be able to manage and control these code snippets in one central place. The Tag Manager itself does not set cookies or store data; it effectively acts as a manager of the tags it contains. Data is collected from the individual tags that are managed. You can find out what data these respective tags collect in the respective sections on the various tools in this privacy policy. The data that is stored by Google in this context is mostly located on Google's own servers, which are distributed around the world. However, most of them are located in the USA. You can find out where the servers are located by clicking on the link below: Datacenters Locations >>

Use of Google Analytics
Our website uses Google Analytics, a web analytics service provided by Google Inc. To disable Google Analytics, Google provides a browser plug-in at GA uses cookies. These are small text files that make it possible to store specific information related to the user on the user's terminal device. These enable an analysis of the use of our website by Google. The information collected by the cookie about the use of our website (including your IP address) is usually transmitted to a Google server in the USA and stored there. In the event that IP anonymisation is activated, however, your IP address will be shortened beforehand by Google within member states of the European Union or in other contracting states to the Agreement on the European Economic Area. Only in exceptional cases will the full IP address be transmitted to a Google server in the USA and shortened there. IP anonymisation is active on our website. We use the data collected by GA to perform analyses on user and user behaviour and to optimise our website as a result, thereby improving the user experience on our website. The data collected will be kept confidential at all times and will not be shared with third parties. You can deactivate the use of GA at any time by installing a simple browser addon. You can find the addon at the following link:

Use of Google Ads
Within our website we use Google Conversion Tracking. This means that when you access our website via an ad placed by Google, a cookie is set on your computer by Google Adwords. These cookies lose their validity after a predefined period of time and are not used for personal identification. If you visit certain pages of our website again and the cookie has not yet expired, we and Google can recognise that you have clicked on an ad and were redirected by it. Cookies vary from client to client, each receiving an individual one. With the help of this conversion (cookie) tracking, we learn the total number of users who clicked on an ad and were redirected to a corresponding page. However, we do not receive any personal information, so you cannot be identified as an individual. If you do not wish to be tracked, you can set a Do Not Track cookie or set your browser to block cookies from certain domains.

Use of Bing Ads
In addition to Google Ads, we also use Bing Ads. The provider here is the American company Microsoft Corporation. As with Google, with Bing Ads you access our website via ads that have been placed and paid for by us, whereby Microsoft Bing Ads sets a cookie on your computer. This cookie allows us to recognise that you have clicked on ads and which relevant pages you have visited on our website or whether you have performed certain actions, such as downloading a PDF. Again, no personal information is shared, so you cannot be identified as an individual. If you do not wish to have conversion tracking, you can set this in your browser settings.

Use of social media tools
We operate publicly accessible profiles on social networks. You can find out exactly what these are further down in this section. Social networks such as Facebook and Co. can analyse your user behaviour when you visit their website or websites with integrated social media content. Data collection takes place automatically when you are logged in with your user profile via the app or browser. In some cases (to track your behaviour outside of Facebook), data may also be collected through the use of cookies (which are stored on your device) or through the collection of your IP address. With the help of this collected data, it is possible for us to show you interest-based advertising within and outside of social media platforms. If you have an account on the respective platforms, the advertising can be displayed to you on all devices on which you are or were logged in. The data collected by us via the social media presence will be deleted from our systems as soon as the purpose for storing it no longer applies, we are personally requested to delete it or you revoke your consent to its storage. We have no influence on the storage period of the data stored by the operators of the respective social networks for their own purposes. For more information, please visit the privacy policy of the respective social network.

When using the corresponding forms, personal information such as name, e-mail address and the corresponding messages are collected and stored. We use this information to process incoming enquiries and orders or to filter spam enquiries.
