We use the following service providers: Google Analytics, Google Ads, Google Tag Manager, SC-Networks, Softgarden, Zoom, YouTube and our hosting partner.


Data transmission to third-party countries

We occasionally transmit personal data to a third-party country outside the EU. In doing so, we ensure an appropriate data protection level: A transmission of personal data will only occur if the general principles of data transmission on the basis of Article 44 ff. GDPR apply.



We use cookies on our websites. Cookies are small text files that can be saved on your computer and read. A distinction is made between session cookies, which are deleted again as soon as you close your browser window and permanent cookies, which are stored beyond the single session. Cookies may contain data that make it possible to identify the device used. However, some cookies merely contain information on certain settings that cannot be related to specific persons. We use session cookies and permanent cookies on our websites. The processing is carried out on the basis of Article 6 (1) (f) GPDR and in the interest of optimising or enabling user navigation and adjusting the presentation of our website.


You can set your browser so that it informs you of the placement of cookies. This makes the use of cookies transparent for you. You can also delete cookies at any time via the corresponding browser settings and prevent the setting of new cookies. Please note that our websites may then no longer be displayed optimally and some functions will not be technically available.


Download and contact form

On our website, you may use a contact form to enter personal data. If you use the contact form, we collect and store the data you enter in the input screen (e.g. second name, first name, email address). There will be no forwarding to any third parties.

If consent is given, the legal basis for the processing is Article 6 (1) (a) GDPR. If your request has the purpose of preparing the signing of a contract, Article 6 (1) (b) GDPR is an additional legal basis. We use the data only to process and answer your request.

We process and store your data only for as long as it is required for the processing or for complying with statutory duties. Once the purpose of processing no longer exists, your data will be blocked or erased. If there are any additional statutory duties to store the data, we block or erase your data upon the lapse of the statutory storing periods.


Google Analytics, Google Tag Manager

For the need-compliant design of our website, we create pseudonym usage profiles with the use of Google Analytics. Google Analytics uses cookies that are saved on your computer and read by us. This allows us to identify returning visitors and count them. Data processing is carried out on the basis of Article 6 (1) (a) GDPR and in the interest of learning how frequently our websites are accessed by different users. The information about your use of this website generated by the cookie is generally transmitted to a server of Google in the US and stored there. As we have activated IP anonymisation on this website, your IP address is, however, first shortened by Google within the member states of the European Union. Only in exceptional cases is the full IP address transferred to a server of Google in the US and only shortened there. We have concluded a data processing agreement under Article 28 GDPR with Google Inc. (USA). Google will therefore only use all information strictly for the purpose of analysing the use of our website for us and compiling reports on the website activities. We delete user and event data in Google Analytics after 14 months.


You can withdraw your consent for processing at any given time. To this end, please use one of the following options: You can prevent the storage of cookies by making corresponding settings in your browser software; however, we would like to point out that you may not be able to use all functions of this website to their full extent. You can also prevent the entry of the data created by the cookie and relating to your use of the website (incl. your IP address) to Google as well as the processing of these data by downloading the browser plug-in available at the following link ( and installing it. You can also prevent any recording by Google Analytics by clicking on the following link: Click here to opt-out of Google Analytics processing your data. An opt-out cookie is set, which permanently prevents the future collection of your data when visiting this website. Please note: This opt-out cookie only applies to the browser you used when setting the opt-out, not for any other browser you may be using on your computer or on other devices. Should you delete all cookies in this browser, the opt-out cookie will be deleted as well.

Google Ads

As an Ads customer, we also use Google Conversion Tracking, an analysis service of Google. In this process, Google Adwords places two Double-click cookies on your computer (conversion cookie), if you reached our website via a Google ad. These cookies become invalid after 30 days and are not used for personal identification. When you visit certain websites of ours and the cookie has not yet expired, we and Google can identify that someone clicked the ad and was thereby directed to our site. Each Ads-customer gets a different cookie. Cookies can therefore not be tracked over the websites of Ads-customers. The information obtained with the use of the conversion cookie serve to create the conversion statistics for Ads-customers who have opted for conversion tracking. The Ads-customers learn the total number of users that clicked on their ad and were directed to a page featuring a conversion tracking tag. However, they do not receive any information that allows identifying the user personally. If you do not wish to participate in the tracking procedure, you can also reject the necessary setting of a cookie - for instance via browser settings, which deactivates the automatic setting of cookies in general. You can also deactivate cookies for conversion tracking by setting your browser in such a way that cookies are blocked by the domain.



We are embedding Videos on our website which are not stored on our own servers. For this, we use a YouTube Plug-In with Google YouTube as a third party supplier. We avoid the automatic upload of the third party supplier data when opening a page with an embedded video by first displaying a server stored preview image of the video. Thus, the third party supplier will not at first receive any data.

Only after you have clicked on this preview image, third party data will be uploaded. The third party supplier will then receive information about you having accessed this page as well as technical user data. He will also be able to implement tracking technology. We have no influence on this or the terms of processing your data by this third party supplier. By clicking on the preview image you give us your permission to upload third party supplier data. Video embedding is based Article 6 (1) (a) GDPR if your permission is given by clicking the preview image. Please note that video embedding leads to processing of your data in countries outside the European Union. In some of these countries there is risk of government administration and institutions having access to your data in order to monitor and ensure security, without informing you about it and without a right to appeal against this.

In case we use third party suppliers in unsafe third countries and you consent to this, data transfer to an unsafe third country is legally based on Article 49 (1) (a) DSGVO.


Supplier Adequate level of data protection Withdrawal of consent
YouTube / Google (USA) Inadequate level of data protection. Data transfer is legally based on
Art. 49 (1) (a) GDPR
If you have clicked on a preview image third party data will be uploaded immediately. If you do not wish this, do not click on any preview image on our website.
