Privacy Policy

1. Privacy at a Glance

The following information provides a simple overview of what happens to your personal data when you visit this website. Personal data is any data with which you could be personally identified.

Optional usage analysis is provided through Google Analytics. It is disabled by default and Google's analytics script is not loaded until you explicitly consent. No third-party advertising services are used.

The legal bases for the processing described below result from the General Data Protection Regulation (GDPR) and the German Telecommunications Digital Services Data Protection Act (TDDDG).

2. Data Controller

3. Hosting and Content Delivery

This website is hosted on our own server. Traffic is routed through the Content Delivery Network (CDN) of Cloudflare, Inc. (101 Townsend St, San Francisco, CA 94107, USA). Cloudflare may technically have access to your IP address and other connection data.

The use of Cloudflare is based on our legitimate interest in secure and efficient provision of our website (Art. 6(1)(f) GDPR). Cloudflare is certified under the EU-U.S. Data Privacy Framework. More information can be found in Cloudflare's Privacy Policy.

4. Server Log Files

Each time this website is accessed, information automatically transmitted by your browser is collected:

• Browser type and version
• Operating system used
• Referrer URL
• IP address
• Time of the request

This data is not combined with other data sources. Legal basis is Art. 6(1)(f) GDPR (legitimate interest in ensuring trouble-free operation).

5. Web Analytics (Google Analytics)

If you consent, this website loads the Google Tag Manager container GTM-NRPBMMG9 provided by Google Ireland Limited (“Google”), Gordon House, Barrow Street, Dublin 4, Ireland. The container is intended to deliver the configured Google Analytics tag without duplicating direct measurement. Google Analytics uses cookies to analyze your use of the website. Information generated about your use may be transmitted to Google servers, including in the USA, and stored there.

Google Analytics 4 anonymizes IP addresses by default. Your IP address is not stored by Google in full form.

Google will use this information on our behalf to evaluate your use of the website, to compile reports on website activity, and to provide us with other services relating to website and internet usage. The IP address transmitted by your browser as part of Google Analytics will not be merged with other Google data.

You can prevent cookie storage by adjusting your browser settings. You can also prevent Google from collecting and processing the data generated by the cookie by downloading and installing the browser plugin available at: https://tools.google.com/dlpage/gaoptout.

Google Analytics is not loaded before your consent. The legal basis for the analytics processing is your consent under Art. 6(1)(a) GDPR; access to or storage of information on your device is based on § 25(1) TDDDG. You may change or withdraw your choice at any time. Withdrawal stops future analytics requests from this browser where technically possible and removes accessible Google Analytics cookies; it does not affect processing that took place before withdrawal.

6. Contact Form

If you send us an inquiry via the contact form, your details (name, email address, message) will be stored for the purpose of processing the inquiry and in case of follow-up questions. This data will not be shared without your consent.

Legal basis is Art. 6(1)(b) GDPR (pre-contractual measures) or Art. 6(1)(f) GDPR (legitimate interest in effective processing of inquiries).

7. Spam Protection (Cloudflare Turnstile)

The contact form is protected by Cloudflare Turnstile. Turnstile is a service by Cloudflare, Inc. (101 Townsend St, San Francisco, CA 94107, USA) that detects automated access (spam/bots) without requiring a traditional CAPTCHA puzzle.

The Turnstile script is only loaded when you interact with the contact form (e.g., click an input field). Connection data (including your IP address) is then transmitted to Cloudflare.

Legal basis is Art. 6(1)(f) GDPR (legitimate interest in protection against abusive use of the contact form). Integration only occurs during active form use and is therefore technically necessary within the meaning of § 25(2)(2) TDDDG.

More information: Cloudflare Privacy Policy.

8. Local Browser Storage

This website uses technically necessary browser storage for the following purposes:

• Language preference: The NEXT_LOCALE cookie remembers the selected language.
• Consent choice: localStorage stores whether optional analytics was accepted or rejected, the policy version, and the time of the decision. The record is valid for up to 180 days.

This storage supports choices explicitly requested by you. The consent record remains in localStorage; the language cookie is included in requests to this website so the selected locale can be served.

9. Fonts

This website uses self-hosted fonts (Inter, Roboto Mono, Space Grotesk). Font files are loaded directly from our own server. No connection to external servers (e.g., Google) is made.

10. Your Rights

Under GDPR, you have the following rights at any time:

• Access (Art. 15 GDPR) to your stored personal data
• Rectification (Art. 16 GDPR) of inaccurate data
• Erasure (Art. 17 GDPR) of your data stored with us
• Restriction (Art. 18 GDPR) of processing
• Data portability (Art. 20 GDPR)
• Objection (Art. 21 GDPR) to processing

To exercise your rights, you may contact us at any time at the address given above.

You also have the right to lodge a complaint with a data protection supervisory authority. The competent authority for us is the State Commissioner for Data Protection and Freedom of Information Baden-Württemberg (www.baden-wuerttemberg.datenschutz.de).

11. SSL/TLS Encryption

For security reasons, this site uses SSL or TLS encryption. You can recognize an encrypted connection by the browser address bar changing from “http://” to “https://” and by the lock icon in your browser bar.

12. Currency of This Privacy Policy

Status: August 2026. We reserve the right to adapt this privacy policy to reflect changes in the law or changes to our website.
