Principles

We process personal data in accordance with Swiss data protection law (FADP). This website is deliberately built to be data-minimal: it uses no cookies, no tracking, no analytics tools, and embeds no content from third-party servers. Even the fonts are served from our own server.

Hosting and server logs

This website is hosted by Infomaniak Network SA, Geneva (Switzerland). When you visit the website, connection data is processed in server log files for technical reasons (IP address, date and time, requested resource, browser type). This data is used solely to operate the website securely and reliably and is not combined with other data sources.

Contacting us

If you contact us by email or use the inquiry form, we process the information you provide solely to answer your inquiry and to handle any resulting business relationship. Data from the inquiry form is transmitted encrypted to our server hosted by Infomaniak (Switzerland) and delivered to us from there by email; it is not stored permanently on the server. If this channel is unavailable, the form instead opens an email in your own mail client. Your data is not shared with third parties.

Your rights

You have the right to request information about the personal data we process about you, and to have it corrected or deleted. An informal message is sufficient. The competent supervisory authority in Switzerland is the Federal Data Protection and Information Commissioner (FDPIC).

Changes

We may update this privacy policy as needed. The version published on this page applies.
