Privacy policy

1. Controller

2. Technical delivery and server logs

When you access this website, the technical hosting service processes the data required to transmit it. This may include the IP address, date and time, requested address, transferred data volume, referrer, browser type, operating system and HTTP status.

Processing is based on Article 6(1)(f) GDPR. Our legitimate interest is the secure, stable and abuse-resistant delivery of the website. Log data is kept only as long as required for operations, troubleshooting and security, then deleted or anonymised unless a statutory duty or specific security incident requires longer retention.

3. Contact

If you contact us by email or telephone, we process your details to respond and, where applicable, to take steps before entering into or performing a contract. The legal bases are Article 6(1)(b) GDPR and, for general communication, Article 6(1)(f) GDPR. Our legitimate interest is the proper handling of your enquiry.

Data is deleted when it is no longer required for its purpose, unless commercial, tax or other statutory retention duties apply.

4. Cookies, analytics and embedded content

This website does not itself use non-essential cookies, audience analytics, profiling or advertising trackers. Fonts and visual assets are delivered locally. Content from GitHub or other platforms is not embedded.

5. External links

The website contains ordinary links to external services, particularly GitHub. A connection to an external provider is made only after you follow such a link. That provider is responsible for the resulting processing and its own privacy information applies.

6. Recipients and processors

We use technical service providers where required to host, operate and protect the website. They process data under our instructions or on their own statutory basis. Transfers outside the European Economic Area take place only where the requirements of Articles 44 et seq. GDPR are met.

7. Your rights

Subject to the statutory conditions, you have rights including:

• access to your personal data (Article 15 GDPR),
• rectification (Article 16 GDPR),
• erasure (Article 17 GDPR),
• restriction of processing (Article 18 GDPR),
• data portability (Article 20 GDPR), and
• objection to processing based on Article 6(1)(e) or (f) GDPR (Article 21 GDPR).

Where processing is based on consent, you may withdraw that consent at any time with future effect. You may also lodge a complaint with a data protection supervisory authority. The competent authority includes the Hessian Commissioner for Data Protection and Freedom of Information.

8. Security and updates

We take appropriate technical and organisational measures to protect processed data. This policy will be updated if the website, its technical delivery or the applicable law changes materially.
