You can use Cookiebot to choose which cookies and tools you want to allow or reject, either individually or by category. This enables you to make an informed decision about sharing your data and allows us to use cookies and tools in a privacy-compliant, transparent, and documented manner.
The consent manager processes your personal data to record your decision regarding the use of cookies and tools and to store it for future visits to our website. This includes the corresponding cookie with your consent decision as well as other usage data, such as IP address, domain name, time of request, server data (e.g., data transfer types, server status, etc.), country, browser, and operating system.

3. Statistical Analysis of Website Usage
Purpose: To statistically analyze the use of our website, we use so-called "cookies"—text files that are stored on your computer and allow us to analyze your browsing behavior. This enables us to improve the quality of our website and its content. We gain insights into how the website is used and can continuously optimize our offering. The information obtained through the statistical analysis of our website is not merged with other data collected on the website.
On our website, we specifically use Google Analytics, a web analytics service provided by Google Inc., which uses cookies. The information generated by the cookie about your use of our website is generally transmitted to a Google server in the USA and stored there. We use Google Analytics on our website with the extension "_anonymizeIp()", which means IP addresses are processed in a shortened form. If IP anonymization is activated on our website, your IP address will be shortened by Google within member states of the European Union or in other contracting states of the Agreement on the European Economic Area before transmission. Only in exceptional cases will the full IP address be transmitted to a Google server in the USA and shortened there.
On our behalf, Google will use this information to evaluate your use of the website, compile reports on website activity, and provide other services related to website and internet usage to the website operator. The IP address transmitted by your browser as part of Google Analytics will not be merged with other Google data.

Your data will only be shared with third parties if permitted or required by law, or if you have given your consent. We also share your data to the necessary extent with service providers we engage in order to deliver our services. In doing so, we limit the disclosure of data to what is strictly necessary to provide our services to you.
Some of our service providers act as data processors and are strictly bound by our instructions when handling your data. Others may act independently with the data we transfer to them.
Below are the categories of recipients of your data:
- Affiliated companies within our corporate group, insofar as they act as processors or independently on our behalf (e.g., providing IT services), or where necessary to fulfill our services or respond to your inquiries;
- IT service providers, marketing agencies, and other contractors who support us in hosting, operating, or designing the website, storing data, or maintaining and administering our systems;
- Legal advisors, for the enforcement of our claims;
- Public authorities and institutions, where we are legally obligated to disclose data.
Additionally, we may share your personal data within our globally operating corporate group, for example with subsidiaries that require the data to fulfill our and/or their contractual and legal obligations or based on legitimate interests. This may include economic, administrative, or other internal business purposes. Such sharing only occurs where your interests or fundamental rights and freedoms requiring the protection of personal data do not override these interests.
Apart from the above, we do not share your data with third parties.
We operate globally and may transfer personal data to countries outside the EU/EEA. Transfers occur only if necessary for contractual obligations, legally required, based on consent, or within data processing agreements.
Transfers comply with Art. 44 ff. GDPR, typically using EU Standard Contractual Clauses or Binding Corporate Rules.
