This site is operated by Hermann Stern, Zurich, Switzerland. Contact: hermann@stern.ch.
This site is largely static and can be browsed without providing any personal data. If you use the contact form, the name, email address, and message you submit are used solely to respond to your enquiry. They are not sold, shared for marketing, or used for any other purpose, and are kept only as long as our correspondence requires.
The site is hosted on Vercel, which processes technical request data (such as IP address and browser type) in server logs for security and operation. Images are delivered via the Cloudinary CDN, which processes the same kind of technical data to serve them. Contact-form messages are delivered to my inbox via Resend. The client portal stores project data with Supabase. These providers act as processors; no data is passed to third parties beyond what serving the site requires.
Traffic is measured with Vercel Analytics — aggregate and cookieless (page views, referrers, country). No personally identifying profiles are built and no data is shared with advertisers.
Only essential cookies are used: a session cookie for the client portal sign-in and a preference for its color theme. No advertising or cross-site tracking cookies are set, and there is nothing to consent to — which is why there is no cookie banner.
Under the Swiss FADP and the GDPR you may request access to, correction of, or deletion of your data at any time. Email hermann@stern.ch and I will handle it directly.
