This is a primarily static website. We do not use analytics services, advertising services, social media tracking, or other third-party tracking technologies.

The website uses only technically necessary technologies required for the secure and proper operation of the website. YouTube videos are provided only after you have actively chosen to load them.

3. Hosting

This website is hosted by:

maxcluster GmbH
Lise-Meitner-Str. 1b
33104 Paderborn
Germany

maxcluster operates its own server infrastructure in a data centre in Frankfurt am Main, Germany. The provider also provides security measures such as firewall protection and protection against network-based attacks. maxcluster states that its hosting infrastructure and data centres are operated in Germany and provides data processing agreements for its customers.

When you access this website, technical information is processed by the hosting infrastructure. This may include, in particular:

  • your IP address,
  • date and time of access,
  • the requested page or resource,
  • information about the browser and operating system used, and
  • technical information required to establish and maintain a secure connection.

This information is processed primarily for the purpose of providing the website, ensuring its technical functionality, and protecting the website and its infrastructure against attacks, misuse, and other security threats.

The legal basis for this processing is Article 6(1)(f) GDPR, based on our legitimate interest in providing a secure, stable, and technically functional website.

Where required by applicable data protection law, we have entered into an appropriate data processing agreement with our hosting provider.

4. Technically Necessary Cookies

This website uses only technically necessary cookies and similar technologies that are required for the secure and proper operation of the website.

These technologies may be used, for example, to:

  • protect the website against malicious requests and attacks;
  • maintain the security of the website;
  • detect and prevent misuse;
  • maintain necessary technical or session information; and
  • ensure the proper functioning of the website.

These cookies are not used for advertising, behavioural profiling, cross-site tracking, or web analytics.

Because these technologies are technically necessary for the provision and security of the website, consent is not required where the applicable legal requirements for technically necessary cookies are met.

5. YouTube Videos

This website contains videos provided by YouTube.

For privacy reasons, YouTube videos are not loaded automatically when you visit the website.

Instead, the video is initially displayed as a placeholder. A connection to YouTube is established only if you actively click the button to enable or load the video.

Until you actively enable the video, no YouTube content is loaded and no connection to YouTube is established through the video.

Once you actively enable a video, your browser establishes a connection to YouTube. In this process, information such as your IP address, the URL of the page containing the video, and other technical information may be transmitted to Google. Google states that such information may be transmitted when YouTube content is embedded on third-party websites.

YouTube is a service provided by Google Ireland Limited for users in the European Economic Area. Google operates YouTube as part of its services and provides information about its processing of personal data in its Privacy Policy.

6. Enabling and Disabling YouTube Videos

You are free to decide whether to load a YouTube video.

The video is loaded only after you have actively selected the corresponding option.

You may withdraw or disable this permission at any time by using the corresponding privacy or video settings on this website.

If you withdraw the permission, no further YouTube content will be loaded unless you actively enable it again.

Please note that withdrawing permission does not affect the lawfulness of any processing that took place before the withdrawal.

7. Legal Basis for YouTube Content

The processing of personal data associated with loading YouTube content is based on your active consent pursuant to Article 6(1)(a) GDPR, where consent is required under applicable law.

The website does not require you to enable YouTube videos in order to use its other content and functions.

If you do not enable a YouTube video, no connection to YouTube is established through that video.

8. Data Retention

We retain personal data only for as long as necessary for the purposes described in this Privacy Policy or as required by applicable law.

Technical server and security logs may be retained for a limited period where necessary for the operation, security, and troubleshooting of the website.

The specific retention periods may depend on the technical configuration of the hosting and security infrastructure.
