AI chat / KI-Chat

When you send a chat message, this site sends your question, a limited recent conversation history and Julian’s public profile to OpenRouter and the provider serving Qwen3.7 Flash to generate an answer. This happens only when you send a message, not when you open the chat. The chat is an AI assistant, not a conversation with Julian.

This application does not save chat messages in a database, browser storage or analytics. The visible conversation is kept in page memory and is cleared by a new chat, page navigation or a reload. To limit abuse, Upstash Redis in Frankfurt stores request timestamps, random request IDs and pseudonymized network identifiers. These counters expire after at most 24 hours of inactivity; chat texts and raw IP addresses are not sent to Redis. OpenRouter and its model providers have their own processing and retention policies. Avoid sharing confidential or sensitive information.

Beim Senden gehen deine Frage, ein begrenzter Gesprächsverlauf und Julians öffentliches Profil an OpenRouter und den Anbieter des Qwen3.7-Flash-Modells. Die Anwendung speichert deine Nachrichten nicht dauerhaft und übermittelt sie nicht an die Seitenanalyse. Der Verlauf wird bei einem neuen Chat, Seitenwechsel oder Neuladen gelöscht. Für Anfragelimits speichert Upstash Redis in Frankfurt Zeitstempel, zufällige Anfrage-IDs und mit einem privaten Schlüssel pseudonymisierte Netzwerkkennungen. Die Zähler verfallen spätestens nach 24 Stunden ohne weitere Anfrage; Chattexte und unveränderte IP-Adressen werden nicht an Redis gesendet. Für die Verarbeitung durch OpenRouter und den Modellanbieter gelten deren eigene Datenschutzregeln. Bitte teile keine vertraulichen oder sensiblen Informationen. Du sprichst mit einer KI, nicht mit Julian.

Website analytics

The production site uses Vercel Web Analytics to understand which pages people visit. Query strings, URL fragments, and form contents are excluded from the analytics events this site sends. The integration respects the browser’s Do Not Track and Global Privacy Control settings.

Basic page statistics are enabled. If custom event tracking is activated, it records a fixed action name, such as a CV download or contact click, and the public page where it occurred.

How Vercel Web Analytics handles data

Hosting and external services

Vercel hosts the site and processes requests to deliver it. Links to LinkedIn, GitHub, product websites, and any connected booking provider open services with their own privacy practices.
