5. Analysis tools

a) Tracking tools

The tracking measures listed below and used by us are carried out on the basis of Art. 6 para. 1 sentence 1 (f) GDPR. With the tracking measures used, we want to ensure that our website is designed to meet requirements and is continually optimized.

This information may also be transferred to third parties if this is required by law or if third parties process this data on behalf of the company. Under no circumstances will your IP address be merged with other data from Google. The IP addresses are anonymized so that an assignment is not possible, (IP masking). You may refuse the use of cookies by selecting the appropriate settings on your browser, however please note that if you do this you may not be able to use the full functionality of this website.

c) Google Adwords Conversion Tracking

We also use Google Conversion Tracking to statistically record and evaluate the use of our website for the purpose of optimizing it for you. Google Adwords will set a cookie (see paragraph 4) on your computer if you have accessed our website via a Google ad. These cookies expire after 30 days and are not used for personal identification. If the user visits certain pages of the Adwords customer's website and the cookie has not yet expired, Google and the customer can recognize that the user has clicked on the ad and has been redirected to this page. Each Adwords customer receives a different cookie. Cookies cannot therefore be traced via the websites of Adwords customers. The information collected using the conversion cookie is used to generate conversion statistics for Adwords customers who have opted for conversion tracking. Adwords customers see the total number of users who clicked on their ad and were redirected to a page with a conversion tracking tag. However, you will not receive any information that personally identifies users. If you do not wish to participate in the tracking process, you can also reject the setting of a cookie required for this - for example using a browser setting that generally deactivates the automatic setting of cookies. You can also deactivate cookies for conversion tracking by setting your browser to block cookies from the "" domain. Google's privacy policy for conversion tracking can be found here: ( ).

The underlying advertising purpose is to be regarded as a legitimate interest within the meaning of the GDPR. Responsibility for data protection-compliant operation must be guaranteed by the respective provider.

We use YouTube in conjunction with the "Advanced Privacy Mode" feature to show you videos. The legal basis is Art. 6 para. 1 (f) GDPR. Our legitimate interest lies in improving the quality of our Internet presence. According to YouTube, the "Extended data protection mode" function means that the data specified below will only be transmitted to the YouTube server if you actually start a video.

Without this "Extended Privacy Policy", a connection to the YouTube server in the USA will be established as soon as you access one of our Internet pages on which a YouTube video is embedded.

This connection is required in order to be able to display the respective video on our website via your Internet browser. In the course of this, YouTube will at least record and process your IP address, the date and time as well as the website you visited. In addition, a connection to the Google advertising network "DoubleClick" is established.

If you are logged in to YouTube at the same time, YouTube will assign the connection information to your YouTube account. If you wish to prevent this, you must either log out of YouTube before visiting our website or make the appropriate settings in your YouTube user account.

For the purpose of functionality and analysis of usage behavior, YouTube permanently stores cookies via your Internet browser on your terminal. If you do not agree to this processing, you have the option of preventing the storage of cookies by setting it in your Internet browser.
