Operator status

Legal status

This website is the personal online presence of a private natural person. There is no commercial registration (kein Handelsregistereintrag), no VAT-ID (keine Umsatzsteuer-Identifikationsnummer) and no regulatory supervisory body applicable to its operation.

The site serves as a self-presentation, a public archive of the operator's own writing (Library, Podcast) and a contact surface for potential engagements. Concrete consulting services, where contracted, are performed off-platform on the basis of a separate written agreement; this website does not process orders, payments, or contractual transactions.

Should you require a postal address for legitimate legal correspondence (e.g. statutory service of process), please request it in writing to the legal email above. The operator will provide a ladungsfähige Anschrift in good faith and without unreasonable delay upon a substantiated request.

AI system disclosure (Art. 50 EU AI Act)

This website provides information about interaction with its AI assistant Calixa under Article 50(1) of Regulation (EU) 2024/1689. The general application date in Article 113 is 2 August 2026. This disclosure is not a certification of compliance.

Calixa is an AI system. When you interact with it you are interacting with an AI, not a human operator.
Calixa sends your question and selected context through OpenRouter to the configured model provider. When external query embedding is enabled, query text is also sent to Cohere. Provider handling depends on the applicable service terms and configuration; this site does not establish a universal no-training guarantee for every provider.
Calixa uses retrieval-augmented generation over a curated, embedded record set (CV, skills profile, publications). It does not browse the open web at request time.
Outputs are AI-generated, may contain errors, and must not be relied upon for legal, medical, financial or contractual decisions.
User inputs are processed transiently to produce a response. Per-session conversational memory is described in the Privacy Policy.
