This website is provided via ChatGPT Sites by OpenAI Ireland Limited. When you visit it, technically necessary data such as your IP address, browser information, access time and pages viewed are processed. This serves to provide and secure the website. ChatGPT Sites also automatically records page views and individual visitors; I am shown only aggregated visitor numbers.

A technically necessary Cloudflare security cookie is used to protect against abusive access. Data may also be processed outside Switzerland, particularly in the USA. No additional analytics, advertising or marketing services are used.

Vimeo videos are embedded on the VIDEO page. Initially, only locally stored preview images are displayed. A connection to Vimeo is established only when a video is played; in particular, the IP address and technical usage data may then be transmitted to Vimeo and technically necessary cookies may be set. The Vimeo player is loaded with the “Do Not Track” setting enabled.

If you contact me by email, I use your information solely to process your enquiry. You may request access to, correction or deletion of your personal data at the address above.
