Cookie Policy

This Cookie Policy explains which cookies, local storage entries, tags, pixels, scripts and comparable technologies may be used on this website.

It supplements the Privacy Policy, the Cookie Settings and the “Third-Party Services” page.

Cookies are small text files that may be stored in the browser or on the terminal device.

Similar technologies include, for example:

• local storage,
• session storage,
• pixels,
• tags,
• scripts,
• device or browser identifiers,
• server-side or client-side analytics mechanisms.

Such technologies may be technically necessary or may serve optional purposes, such as statistics, user-experience analytics or marketing.

Technically necessary cookies and storage functions are used on the basis of Section 25(2) TDDDG and Article 6(1)(f) GDPR.

Non-essential cookies, tags, pixels and comparable technologies are used only after consent. The legal basis is Section 25(1) TDDDG and Article 6(1)(a) GDPR.

You can withdraw or change your consent at any time via “Cookie Settings”.

This website uses the following categories.

Necessary

This category is always active. It includes functions that are required for the operation of the website or for settings expressly selected by you.

Examples:

• storage of your cookie selection,
• language setting,
• theme or display preference,
• technical status information,
• security-relevant or functional website processes.

These data generally remain in your browser and are not used for advertising tracking.

Statistics

This category covers statistical visit measurement and aggregated analytics.

Possible services:

• Google Analytics 4,
• Cloudflare Web Analytics,
• Vercel Analytics,
• Umami.

Purpose:

• to understand which pages are read,
• to identify technical and content-related usage patterns,
• to improve performance and reading flow,
• to identify errors and points of friction.

Depending on the service and configuration, this category may be cookie-free or cookie-based. Services that are not technically necessary or that access information on the terminal device are activated only after consent.

Usability and Interaction

This category covers UX analytics, heatmaps, interaction analytics and session replays.

Possible services:

• Microsoft Clarity,
• Hotjar,
• Contentsquare,
• Sentry.

Purpose:

• to identify where the website works well,
• to understand where interaction or navigation is unclear,
• to improve layout, readability and operability,
• to identify technical UX issues.

This category may be particularly intrusive. It is activated only after consent. The services are configured, where technically available, so that sensitive entries, confidential form content and personal free-text inputs are not recorded.

Marketing / Professional Reach

This category covers professional reach and campaign analytics.

Possible service:

• LinkedIn Insight Tag.

Purpose:

• to understand in broad terms whether the website is perceived in professional contexts,
• to receive aggregated professional reach and campaign information,
• to enable technical campaign or conversion analytics.

This category is activated only after consent.

This website may use technical verification for Google Search Console, Bing Webmaster Tools and Baidu.

These verifications typically take place via meta tags, HTML files or DNS records. They serve to prove that I manage the website.

This verification is not the same as web analytics or marketing tracking. Search engines may, however, retrieve the relevant information during crawling.

You may change or withdraw your selection at any time.

Cookie Settings

If you delete cookies or local storage objects in your browser, the website may no longer recognise your previous selection and may ask you to decide again.

You can also control, block or delete cookies and local storage technologies through your browser.

Please note: if you block technically necessary cookies or local storage functions, certain website functions may be restricted, for example storage of your language, display or cookie selection.

The interactive map view is loaded only when you actively open it. It is not controlled by your analytics or marketing cookie choices.

If the map service used for that view applies its own cookies, local storage or similar technologies, the respective provider's notices apply. Further information can be found in the Privacy Policy and under Third-Party Services.

This Cookie Policy may be updated if the services used, provider information, technical configurations or legal requirements change.

The current published version applies.
