Hosting and Access Data

This website is hosted by Netlify. When you access our pages, so-called server log files are automatically collected by the hosting provider:

These data are used solely for technical monitoring and error analysis. They are not merged with other data sources or analyzed personally.

Cookies and Consent Management (Google CMP / TCF 2.2)

To manage consents for the use of cookies, scripts, and advertising technologies, we use the Consent Management Tool (CMP) provided by Google. This tool is certified according to the TCF 2.2 standard of IAB Europe.

When you first visit our website, a pop-up banner will ask for your preferences regarding cookies and data processing. Depending on your choice, scripts for analytics and personalization are only loaded after explicit consent has been given.

Revocation or Adjustment: You can adjust or completely revoke your consent at any time with effect for the future. Use the “Privacy Settings” link in the footer of this website.

The storage of information on your terminal device or access to information already stored is based on Section 25(1) TDDDG (German Telecommunications Digital Services Data Protection Act). The subsequent processing of personal data is based on your consent pursuant to Art. 6(1)(a) GDPR.

Advertising via Google AdSense

This website uses Google AdSense, a service provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland (“Google”), to display advertisements.

Using the integrated Consent Management Tool, users decide whether Google may personalize ads based on user profiles or whether only non-personalized ads are displayed. When displaying advertisements, the following data may be transmitted to and processed by Google:

For more information, please refer to the Google Privacy Policy and How Google uses information from sites or apps that use our services.

Web Analytics & Tag Management

Google Tag Manager & Google Analytics

We use Google Tag Manager and Google Analytics (services provided by Google Ireland Limited). Google Tag Manager itself does not set cookies and does not collect personal data; it merely manages the loading of other scripts.

Through the integrated Google Consent Mode v2, we ensure that Google Analytics only processes data for statistical measurement after you have granted consent for analytics storage in the consent banner.

Contentsquare

Our website includes a script from the analytics service Contentsquare (Contentsquare SAS, 7 rue de Madrid, 75008 Paris, France). Contentsquare helps us understand how users interact with website content (e.g., scrolling behavior, clicks) to improve user experience. Data processing is pseudonymized and only takes place if you have consented to the analytics category in the consent banner.

Contact

If you contact us via email, your information will be stored to process your request. This data will not be shared with third parties without your explicit consent.

External Content

This site may load content (e.g., illustrations, icons, or fonts) from external services. Due to technical reasons, connection data (e.g., IP address) may be transferred to those services.

Your Rights under the GDPR

Changes

We reserve the right to update this privacy policy occasionally to comply with legal requirements or reflect technical changes.
