We process personal data only as far as necessary for a functional website and for our content and services – in good faith, proportionately and for the stated purpose.

3. Visiting the website / server log files

When you visit, the hosting provider automatically records data in server log files (IP address, date and time, page accessed, browser and operating system, referrer). This data serves secure and stable operation and is deleted after a short period. Hosting provider: Vercel Inc., California (USA); data may thereby be transferred to the USA.

5. AI chat assistant

This website offers an AI-powered chat assistant. The messages you enter are transmitted to our service provider OpenAI (OpenAI, L.L.C., USA) to generate a response and processed there; this may involve a transfer to the USA. Please do not enter sensitive personal data in the chat. More information: openai.com/policies.

6. Cookies and local storage

7. Disclosure to third parties / processors

Your data is only shared with the service providers needed to operate the website (hosting, email delivery, AI chat), which process it solely on our behalf and according to our instructions.

8. Your rights

Within the scope of applicable law, you have the right to access, rectification, erasure and restriction of processing, as well as data portability and objection. Contact: joel [at] lyb.ch.
