Privacy Policy

2. Data Collection on This Website

Server Log Files

When accessing this website, the hosting provider automatically collects and stores technical information in server log files. This includes:

• IP address of the accessing device
• Date and time of the request
• Browser type and version
• Operating system used
• Referrer URL (previously visited page)

Legal basis: Art. 6 (1) (f) GDPR (legitimate interest in ensuring website stability, accessibility, and security).

Hosting (Vercel)

This website is hosted by Vercel Inc., USA. Vercel processes the server log data described above on our behalf as a processor under a data processing agreement pursuant to Art. 28 GDPR. Where data is transferred to the United States, the transfer is safeguarded by the EU Standard Contractual Clauses pursuant to Art. 46 (2) (c) GDPR.

Legal basis: Art. 6 (1) (f) GDPR.

3. Cookies & Local Storage

This website does not use any tracking, marketing, or third-party analytics cookies (such as Google Analytics or Meta Pixel), and it does not set cookies at all.

Instead, your browser's local storage is used to remember your selected display theme (light or dark mode), your custom status preference, and any sketch you make with the built-in drawing mode (press P or via the site menu), so that they survive across visits to this site. All of it stays in your browser — none of this data is transmitted to any server, and you can clear it at any time through your browser settings.

Legal basis: Art. 6 (1) (f) GDPR.

4. Contacting Us

If you contact us via email, the information you provide will be stored for the purpose of processing your inquiry and handling potential follow-up questions.

Legal basis: Art. 6 (1) (b) GDPR (contractual or pre-contractual inquiries) or Art. 6 (1) (f) GDPR.

5. External Services, APIs & Fonts

Typography & Fonts: All web fonts used on this site are self-hosted locally via Next.js asset optimization. No connections to external third-party font servers (such as Google Fonts CDN) are established upon loading pages.

Error Monitoring & Performance (Sentry)

This website uses Sentry to detect errors and monitor performance, provided by Functional Software, Inc. (dba Sentry). Data is processed in Sentry's European data region on servers located within the EU.

The following data may be transmitted when an error occurs or a page is loaded: IP address, browser type and version, operating system, device and screen information, the requested URL and referrer, timestamps, error messages and stack traces, and technical performance and navigation data.

Sentry acts as a processor on our behalf under a data processing agreement pursuant to Art. 28 GDPR. The Sentry SDK does not set cookies on this website, and Session Replay is deliberately not enabled — no recordings of your interactions are created.

Legal basis: Art. 6 (1) (f) GDPR (legitimate interest in a stable, secure and functioning website). You may object to this processing at any time under Art. 21 GDPR using the contact details above.

Voluntary External Links (Contact & /study)

Some links on this website point to external providers and open in a new browser tab only when you actively click them. Until then, no connection to those providers is established and no data is sent to them by this website.

On the homepage, the contact and elsewhere sections link to services such as LinkedIn, Threema, Signal, Bluesky, Mastodon, and X. On the /study page, completed credential entries link to Perplexity AI (Perplexity AI, Inc.) with a pre-filled search question based on the entry title (for example, a qualification name).

When you follow such a link, the respective provider processes data under its own responsibility — for example your IP address, device and browser information, any account data if you are logged in, and (for Perplexity) the search text contained in the link. This website uses a Referrer-Policy: no-referrer header, so the previous page address is generally not transmitted to the destination site.

Legal basis: Art. 6 (1) (a) GDPR (your voluntary decision to open the external link). Please refer to the privacy policies of the respective providers for further details.
