2) Data collection when visiting our website
When using our website for informational purposes only, i.e. when you do not register or otherwise provide us with information, we only collect the data that your browser sends to our server (so-called “server log files”). When you visit our website, we collect the following data, which is technically necessary for us to display the website:
- Our visited website

3) Cookies
To make visiting our website attractive and to enable the use of certain functions, we use so-called cookies on various pages. These are small text files that are stored on your end device. Some of the cookies we use are deleted after the end of the browser session, i.e. after closing your browser (so-called session cookies). Other cookies remain on your terminal device and enable us to recognize your browser the next time you visit us (so-called persistent cookies). If cookies are set, they collect and process certain user information to an individual extent, such as browser and location data and IP address values. Persistent cookies are automatically deleted after a specified period of time, which may vary depending on the cookie. The duration of the respective cookie storage can be seen in the overview of the cookie settings of your web browser.
In some cases, cookies are used to simplify the ordering process by saving settings (e.g. remembering the contents of a virtual shopping cart for a later visit to the website). Insofar as personal data is also processed by individual cookies used by us, the processing is carried out in accordance with Art. 6 Para. 1 letter b DSGVO either for the execution of the contract, in accordance with Art. 6 Para. 1 letter a DSGVO in the case of a granted consent or in accordance with Art. 6 Para. 1 letter f DSGVO to safeguard our legitimate interests in the best possible functionality of the website as well as a customer-friendly and effective design of the site visit.
Please note that you can set your browser so that you are informed about the setting of cookies and can decide individually whether to accept them or to exclude the acceptance of cookies for certain cases or generally. Each browser differs in the way it manages the cookie settings. This is described in the help menu of each browser, which explains how you can change your cookie settings.

4) Making contact
Personal data is collected when contacting us (e.g. via contact form or e-mail). Which data is collected in the case of a contact form can be seen from the respective contact form. These data are stored and used exclusively for the purpose of answering your request or for contacting you and the associated technical administration. The legal basis for the processing of this data is our legitimate interest in answering your request in accordance with Art. 6 para. 1 lit. f DSGVO. If your contact is aimed at the conclusion of a contract, an additional legal basis for the processing is Art. 6 para. 1 lit. b DSGVO. Your data will be deleted after final processing of your request. This is the case if it can be deduced from the circumstances that the matter in question has been conclusively clarified and provided that there are no legal obligations to retain data.
5) Online marketing
Facebook pixels for the creation of custom audiences with advanced data synchronization (with cookie-consent-tool)
Within our online offer the so-called “Facebook pixel” of the social network Facebook is used in the mode of extended data synchronization, which is operated by Facebook Ireland Limited, 4 Grand Canal Quare, Dublin 2, Ireland (“Facebook”).
Based on his or her express consent, when a user clicks on an advertisement placed on Facebook and displayed by us, an addition is added to the URL of our linked page by Facebook pixels. This URL parameter is then written into the user’s browser by a cookie that is set by our linked site itself. In addition, this cookie records specific customer data such as the e-mail address that we collect on our website linked to the Facebook ad during transactions such as purchase transactions, account logins or registrations (extended data reconciliation). The cookie is then read by Facebook Pixel and enables data, including specific customer data, to be forwarded to Facebook.
With the help of the Facebook pixel with extended data synchronization, Facebook is on the one hand able to precisely determine the visitors of our online offer as a target group for the display of ads (so-called “Facebook ads”). Accordingly, we use the Facebook pixel with extended data synchronization to display the Facebook ads placed by us only to those Facebook users who have also shown an interest in our online offering or who exhibit certain characteristics (e.g. interests in certain topics or products determined on the basis of the websites visited), which we transmit to Facebook (so-called “custom audiences”). With the help of the Facebook pixel with extended data matching, we also want to ensure that our Facebook ads correspond to the potential interest of the users and are not annoying. This allows us to further evaluate the effectiveness of Facebook ads for statistical and market research purposes by tracking whether users have been redirected to our website after clicking on a Facebook ad (so-called “conversion”). Compared to the standard Facebook pixel version, the advanced data matching feature helps us better measure the effectiveness of our advertising campaigns by capturing more assigned conversions.
All transmitted data is stored and processed by Facebook so that a connection to the respective user profile is possible and Facebook can use the data for its own advertising purposes, in accordance with the Facebook Data Usage Policy (https://www.facebook.com/about/privacy/). The data may enable Facebook and its partners to place advertisements on and outside of Facebook.
These processing operations are only carried out if express consent is granted in accordance with Art. 6 para. 1 lit. a DSGVO.
Consent to use the Facebook pixel may only be given by users who are older than 16 years of age. If you are younger, please ask your legal guardian for permission.
The information generated by Facebook is usually transferred to a Facebook server and stored there. This may also involve a transfer to the servers of Facebook Inc. in the USA. You can revoke your granted consent at any time with effect for the future. To exercise your revocation, remove the check mark next to the setting for the “Facebook Pixel” in the “Cookie-Consent-Tool” integrated on the website.
6) Web analysis services
Google (Universal) Analytics
Google (Universal) Analytics with Google Signals
This website uses Google (Universal) Analytics, a web analytics service provided by Google Ireland Limited, Gordon House, 4 Barrow St, Dublin, D04 E5W5, Ireland (“Google”). Google (Universal) Analytics uses “cookies”, which are text files placed on your computer, to help the website analyze how users use the site. The information generated by the cookie about your use of this website (including the abbreviated IP address) is usually transferred to a Google server and stored there, and may also be transferred to the servers of Google LLC. in the USA.
This website uses Google (Universal) Analytics exclusively with the extension “_anonymizeIp()”, which ensures anonymization of the IP address by shortening it and excludes the possibility of direct personal reference. Through the extension, your IP address will be shortened by Google within member states of the European Union or in other signatory states of the Agreement on the European Economic Area before. Only in exceptional cases will the full IP address be transferred to a server of Google LLC.in the USA and shortened there. In these exceptional cases, this processing is carried out in accordance with Art. 6 para. 1 lit. f DSGVO on the basis of our legitimate interest in the statistical analysis of user behaviour for optimisation and marketing purposes.
On our behalf, Google will use this information to evaluate your use of the website, to compile reports on website activities and to provide us with further services related to website and internet use. The IP address transmitted by your browser within the scope of Google (Universal) Analytics is not combined with other data from Google.
You can prevent the storage of cookies by adjusting your browser software accordingly. However, we would like to point out that in this case you may not be able to use all functions of this website to their full extent. You can also prevent the collection of data generated by the cookie and related to your use of the website (including your IP address) to Google and the processing of this data by Google by downloading and installing the browser plugin available at the following link:

Further information about Google (Universal) Analytics can be found here: https://policies.google.com/privacy?hl=de&gl=de
This website also uses the Google Signals service as an extension of Google Analytics. With Google Signals, we can have Google generate cross-device reports (so-called “cross device tracking”). If you have activated “personalized ads” in your Google Account settings and you have linked your Internet-enabled devices to your Google Account, Google can analyze user behavior across devices and create database models based on this. The logins and device types of all site visitors who were logged into a Google Account and performed a conversion are taken into account. Among other things, the data shows on which device you clicked on an ad for the first time and on which device the corresponding conversion took place. We do not receive any personal data from Google, but only statistics based on Google Signals. In accordance with Art. 6 Para. 1 lit. f DSGVO, the data is processed on the basis of our predominantly legitimate interest in the statistical analysis of user behavior for optimization and marketing purposes. You can object to the data processing by observing the aforementioned objection possibilities. In addition, you have the option of deactivating your settings in your Google Account for “personalized ads”, please follow the instructions on this page: https://support.google.com/ads/answer/2662922?hl=de
Further information about Google Signals can be found here: https://support.google.com/analytics/answer/7532985?hl=de
Insofar as legally required, we have obtained your consent for the processing of your data as described above in accordance with Art. 6 para. 1 lit. a DSGVO. You can withdraw your consent at any time with effect for the future.
