We process personal data in accordance with the GDPR (DSGVO) and the BDSG. The following information gives a simple overview of what data we collect and what we use it for.
When you visit this website, the server automatically collects and stores information in server log files (e.g., browser type and version, operating system, referrer URL, hostname, time of the server request, IP address). Processing is based on our legitimate interest in the technically error-free presentation and optimization of the website (Art. 6(1)(f) GDPR).
Our website is hosted by an external provider and delivered worldwide via a Content Delivery Network (CDN). This is done to securely and quickly provide our online offering (Art. 6(1)(f) GDPR).
Provider: Vercel, Website: https://vercel.com, DPA: https://vercel.com/legal/dpa

Recipients / Processors
If you send us inquiries via the form, the data provided (e.g., name, email, reason, message) will be processed to handle your request and for follow-up questions, and transmitted by email (SMTP). The legal basis is Art. 6(1)(b) GDPR (pre-contractual measures) and Art. 6(1)(f) GDPR.
The data will be deleted as soon as it is no longer necessary for the purpose of collection, unless legal retention obligations apply.
When you use our chatbot, we process the content of your messages and any data you voluntarily provide in order to answer your inquiry and improve service quality.
Legal basis: Art. 6(1)(b) GDPR (pre‑contractual/contract) and Art. 6(1)(f) GDPR (legitimate interest in efficient customer communication).
Processing by provider: To generate answers, we transmit your prompt to Groq (LLM API). This may involve transfers to third countries with appropriate safeguards (e.g., SCCs).
Retention: We retain chat data only as long as necessary to process the request or as required by law. You can request deletion at any time (subject to statutory retention).
No external data retrieval: replies are generated only from your input and our static site knowledge. We do not scrape third‑party sources via the chatbot.
No storage beyond processing: we do not persist chat content server‑side beyond what is necessary to handle the request.
Roles: We act as the controller; Groq acts as a processor under Art. 28 GDPR.
No profiling or automated decision‑making within the meaning of Art. 22 GDPR is carried out via the chatbot.

If processing is based on your consent, the legal basis is Art. 6(1)(a) GDPR. In the case of performance of a contract or pre-contractual measures, the legal basis is Art. 6(1)(b) GDPR. For compliance with a legal obligation, Art. 6(1)(c) GDPR applies. For the purposes of legitimate interests, Art. 6(1)(f) GDPR applies.
Server logs: 7–30 days (typical).
Contact form (SMTP): until resolution of the request, then deletion (e.g., within 90 days) unless statutory retention applies.
Analytics: according to GA4 settings; we aim for the shortest feasible retention.
Chatbot: no storage beyond processing.
You have the right to lodge a complaint with a supervisory authority, in particular in the Member State of your habitual residence, place of work or the place of the alleged infringement.
