We have written this privacy statement to explain to you, in accordance with the requirements of the General Data Protection Regulation (EU) 2016/679, what information we collect, how we use data and what decision-making options you have as a visitor to this website. Unfortunately, it is in the nature of things that these explanations sound very technical, but we have tried to describe the most important things as simply and clearly as possible when creating them.
Our website uses HTTP cookies to store user-specific data.
What exactly are cookies?
Whenever you browse the Internet, you use a browser. Popular browsers include Chrome, Safari, Firefox, Internet Explorer, and Microsoft Edge. Most websites store small text files in your browser. These files are called cookies. These cookie files are automatically placed in the cookie folder of your browser. A cookie consists of a name and a value. When you define a cookie, you must also specify one or more attributes.
Cookies store certain user data about you, such as language or personal page settings. When you return to our site, your browser transmits the "user-related" information back to our site. Thanks to cookies, our site knows who you are and offers you your usual default setting. In some browsers each cookie has its own file, in others all cookies are stored in a single file.
There are both first-party cookies and third-party cookies. First-party cookies are created directly by our site, third-party cookies are created by other parties (e.g. Google Analytics). Each cookie must be evaluated individually, as each cookie stores different data. Also, the expiration time of a cookie varies from a few minutes to a few years. Cookies are not software programs and do not contain viruses, Trojans or other "pests". Cookies also cannot access information on your PC.
For example, cookie data may look like this:
- Name: _ga
- Expiration: 2 years
- Use: Distinction of website visitors.
- Example value: GA1.2.1326744211.152311233784
What types of cookies are used on this website?
Basically, two types of cookies are used on this website:
These cookies are necessary to ensure basic website functionality. For example, it needs these cookies to save your privacy settings. You can set your browser to block these cookies or to notify you about these cookies. However, some essential areas of the website may not work then.
performance cookies / cookies for website analysis
In order to better analyze and optimize our website, we use Google Analytics, a web analytics service provided by Google, LLC ("Google"). Cookies are used for this purpose. If you refuse the use of these cookies, we can no longer determine when you have accessed the website. If many users refuse us such consent, the future development of the website may be limited.
How can I block or delete cookies?
If you do not want to allow the performance cookies (necessary for Google Analytics) of our site, you can regulate this through our cookie consent manager. Regardless of which service or website the cookies come from, you also usually have the option to delete, only partially allow, or disable cookies in your browser settings. For example, you can block third-party cookies, but allow all other cookies.
If you want to find out which cookies have been stored in your browser, if you want to change or delete cookie settings, you can find this in your browser settings:
Internet Explorer: Delete and manage cookies
- Microsoft Edge: Delete and manage cookies
If you do not want to have cookies in principle, you can set up your browser so that it always informs you when a cookie is to be set. In this way, you can decide for each individual cookie whether you allow the cookie or not. The procedure varies depending on the browser. The best way is to search the instructions in Google with the search term "delete cookies Chrome" or "disable cookies Chrome" in case of a Chrome browser or exchange the word "Chrome" for the name of your browser, e.g. Edge, Firefox, Safari.
Evaluation of visitor behavior (Google Analytics)
We use the analysis tracking tool Google Analytics (GA) of the American company Google, LLC on our website. For the European area, the company Google Ireland Limited (Gordon House, Barrow Street Dublin 4, Ireland) is responsible for all Google services. Google Analytics collects data about your actions on our website. For example, when you click on a link, this action is stored in a cookie and sent to Google Analytics. Using the reports we receive from Google Analytics, we can better tailor our website to your preferences. In the following, we will go into more detail about the tracking tool and inform you in particular about what data is stored.
What is Google Analytics?
Google Analytics is a tracking tool used for traffic analysis of our website. In order for Google Analytics to work, a tracking code is executed by Google Analytics if the user has given permission. When you visit our website and have consented to the use of tracking cookies, this code records various actions you take on our website. This data is sent to the Google Analytics servers and stored there. Google processes the data and we receive reports about your user behavior. These reports may include, but are not limited to, the following:
- Target group reports: Through target group reports we get to know our users better and can thereby understand who is interested in our website.
- Acquisition reports: Acquisition reports give us helpful information about how users arrive at our website.
- Behavioral reports: This tells us how you interact with our website. We can track which path you take on our site and which links you click.
- Real-time reports: Here we always know immediately what is happening on our website. For example, we can see how many users are reading a text.
Why do we use Google Analytics on our website?
Our goal is to better understand the users of our website and thus be able to optimize our website offering The statistics and data from Google Analytics help us achieve this goal.
The statistically analyzed data shows us a clear picture of the strengths and weaknesses of our website. On the one hand, we can optimize our site so that it can be found more easily by interested people on Google. On the other hand, the data helps us to better understand you as a visitor. We thus know very well what we need to improve on our website in order to offer you the best possible experience.
What data is stored by Google Analytics?
Google Analytics uses a tracking code to create a random, unique ID that is associated with your browser cookie. This is how Google Analytics recognizes you as a new user. The next time you visit our site, you will be recognized as a "returning" user. All collected data is stored together with this user ID. This makes it possible to evaluate pseudonymous user profiles in the first place.
Through identifiers such as cookies and app instance IDs, your interactions on our website are measured. Interactions are all types of actions that you perform on our website. If you also use other Google systems (such as a Google account), data generated via Google Analytics can be linked to third-party cookies. The following cookies can be used by Google Analytics:

Here we show you an overview of the most important data that is collected with Google Analytics:
Heatmaps: Google creates so-called heatmaps. Via heatmaps you can see exactly those areas that you click on. This gives us information about where you are "on the go" on our site.
Session duration: Google refers to the time you spend on our site without leaving the page as session duration. If you have been inactive for 20 minutes, the session ends automatically.
Bounce rate: A bounce is when you view only one page on our website and then leave our website again.
IP address: The IP address is only recorded in shortened/anonymized form so that no clear assignment is possible. (IP addresses are still not visible to us in Google Analytics).
Location: The IP address can be used to determine the country and your approximate location. This process is also called IP location determination.
Technical Information: Technical information includes, but is not limited to, your browser type, your ISP, or your screen resolution.
Source of origin: Google Analytics, or us, is of course also interested in which website or which advertisement you came to our site from. The list does not claim to be complete and only serves as a general orientation of the data storage by Google Analytics.
Where is the data stored?
Google has distributed its servers all over the world. Most servers are located in America and consequently your data is mostly stored on American servers. You can read exactly where Google data centers are located here:
- https://www.google.com/about/datacenters/inside/locations/?hl=de Your data is also distributed on different physical data carriers. This has the advantage that the data can be retrieved more quickly and is better protected against manipulation. In each Google data center, there are appropriate emergency programs for your data. For example, if Google's hardware fails or natural disasters paralyze servers, the risk of service interruption remains with Google. Google Analytics remains an active participant in the EU-U.S. Privacy Shield Framework, which governs the accurate and secure transfer of personal data. You can find more information about this at
