Our website uses cookies. These are small text files that your web browser stores on your terminal device. Cookies help us to make our offer more user-friendly, effective and secure.

Some cookies are "session cookies." Such cookies are deleted by themselves after the end of your browser session. On the other hand, other cookies remain on your terminal device until you delete them yourself. Such cookies help us to recognize you when you return to our website.

With a modern web browser, you can monitor, restrict or prevent the setting of cookies. Many web browsers can be configured to automatically delete cookies when you close the program. Disabling cookies may result in limited functionality of our website.

The setting of cookies, which are necessary for the exercise of electronic communication processes or the provision of certain functions desired by you (e.g. shopping cart), is based on Art. 6 para. 1 lit. f DSGVO. As the operator of this website, we have a legitimate interest in storing cookies for the technically error-free and smooth provision of our services. If other cookies are set (e.g. for analysis functions), these are dealt with separately in this privacy policy.

Our website uses functions of the web analysis service Google Analytics. The provider of the web analytics service is Google Inc, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA.

Google Analytics uses "cookies." These are small text files that your web browser stores on your terminal device and enable an analysis of website usage. Information generated by means of cookies about your use of our website is transmitted to a Google server and stored there. The server is usually located in the USA.

The setting of Google Analytics cookies is based on Art. 6 (1) lit. f DSGVO. As the operator of this website, we have a legitimate interest in analyzing user behavior in order to optimize our website and, if necessary, advertising.

IP anonymization

We use Google Analytics in conjunction with the IP anonymization function. It ensures that Google truncates your IP address within member states of the European Union or in other contracting states of the Agreement on the European Economic Area before transmission to the USA. There may be exceptional cases in which Google transfers the full IP address to a server in the USA and shortens it there. On our behalf, Google will use this information for the purpose of evaluating your use of the website, compiling reports on website activity and providing us with other services relating to website activity and internet usage. The IP address transmitted by Google Analytics is not merged with other Google data.

Browser Plugin

The setting of cookies by your web browser can be prevented. However, some functions of our website may be restricted as a result. You can also prevent the collection of data regarding your website usage, including your IP address and subsequent processing by Google. This is possible by downloading and installing the browser plugin accessible via link.

Objection to data collection

You can prevent the collection of your data by Google Analytics by clicking on the following link. An opt-out cookie will be set that will prevent the collection of your data during future visits to our website: Disable Google Analytics.

For details on how Google Analytics handles user data, please see Google's privacy policy.

Order processing

To fully comply with the legal data protection requirements, we have concluded an order processing agreement with Google.

Demographic characteristics with Google Analytics

Our website uses the "demographic characteristics" function of Google Analytics. It can be used to create reports that contain statements about the age, gender and interests of site visitors. This data comes from interest-based advertising from Google as well as visitor data from third-party providers. It is not possible to assign the data to a specific person. You can deactivate this function at any time. This is possible via the ad settings in your Google account or by generally prohibiting the collection of your data by Google Analytics, as explained in the point "Objection to data collection".

We have social network profiles (listed below) in order to make contact with active users on these platforms. When accessing the relevant networks, the respective terms and conditions and privacy policies of the relevant operators apply. We only process the data of users if they contact us within the social networks, i.e. post on our profile pages or send us messages, for example.

Our social media profiles:

For integration and display of video content, our website uses plugins from YouTube. The provider of the video portal is YouTube, LLC, 901 Cherry Ave, San Bruno, CA 94066, USA.

When a page with an integrated YouTube plugin is called up, a connection to the YouTube servers is established. This tells YouTube which of our pages you have accessed. YouTube can assign your surfing behavior directly to your personal profile if you are logged into your YouTube account. You can prevent this by logging out of your YouTube account.

YouTube is used in the interest of an appealing presentation of our online offers. This represents a legitimate interest within the meaning of Art. 6 Para. 1 lit. f DSGVO.

Details on the handling of user data can be found in the YouTube privacy policy.

Our website uses web fonts from Google. The provider is Google Inc, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA.

By using these web fonts, we can show you our website in the appropriate design, regardless of which fonts you use locally. This is done by retrieving the Google Web Fonts from a Google server in the USA and the associated transfer of your data to Google. This is your IP address and which of our pages you have visited. The use of Google Web Fonts is based on Art. 6 para. 1 lit. f DSGVO. As the operator of this website, we have a legitimate interest in the optimal presentation and transmission of our website.

The company Google is certified for the us-European data protection agreement "Privacy Shield". This data protection agreement is intended to ensure compliance with the level of data protection applicable in the EU.

Details about Google Web Fonts can be found here and further information can be found in Google's privacy policy.


On our website we use the function reCAPTCHA (provider: Google Ireland Ltd, Gordon House, Barrow Street, Dublin, 4, Ireland). This serves the purpose of protecting our contact form. Through reCAPTCHA, it can be distinguished whether the input in a form is made by a machine or by a human, so that there is protection against improper, automated processing.

To our knowledge, when reCAPTCHA is used, the referrer URL, the IP address, the behavior of the users of our website, as well as information about the operating system, browser and dwell time, cookies, display instructions, scripts or even the input behavior of the user in the area of the reCAPTCHA checkbox are transmitted to the provider. Your personal data (e.g. your IP address) will not be merged with other data of the provider, unless you have a Google account and are logged into it at that time. If you do not want this, please log out of your Google account before using our contact form.

You can find more information about reCAPTCHA and the Google privacy policy here.

The processing of your data (e.g. the IP address) is a legitimate interest for us according to Art. 6 para. 1 lit. f DSGVO.

On our websites, we use the conversion tracking of Google (provider: Google Ireland Ltd, Gordon House, Barrow Street, Dublin, 4 Ireland), now part of Google Ads. If you have reached our website by clicking on an advertisement placed by Google, Google AdWords will set a so-called cookie on your terminal device. These cookies have a validity period of 30 days and are not used for personal identification. If you visit certain subpages of our online presence and the cookie is still valid, we and also Google can recognize that you have clicked on the ad and have been redirected to the subpage in question. Each AdWords customer receives a different cookie. Cookies can therefore not be tracked via the websites of AdWords customers.

The information obtained through conversion cookies is used to create conversion statistics for AdWords customers who have opted in to conversion tracking. These customers are told the total number of users who clicked on their ad and were redirected to a site tagged with a conversion tracking tag. However, no information is transmitted that can be used to personally identify users. The legal basis for the use of Google AdWords is Art. 6 para. 1 p. 1 lit. f DSGVO.

For more information about and handling of cookies, please read the relevant section in this privacy policy.

If you do not wish to participate in tracking, you can refuse the setting of a cookie required for this, e.g. by means of browser settings that generally deactivate the automatic setting of cookies or block cookies from the domain. You may not delete the opt-out cookies as long as you do not want any data collection. If you delete this or all cookies, you must set the opt-out cookie again.

We use comprehensive security measures in order to protect the data that we save against manipulation and illegitimate access by unauthorised persons. We update our security measures on an ongoing basis.
