Hosting and delivery of enquiries

This website is hosted on the global network of Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, USA. Delivery of the website involves the processing of connection data such as the IP address, which is necessary for the technically secure operation of the site.

Enquiries submitted through the contact form are delivered by email through Sendinblue SAS, trading as Brevo, 106 boulevard Haussmann, 75008 Paris, France. In doing so, Brevo processes the data you entered in the form for the purpose of transmitting it, on our behalf and on our instructions.

Both providers process data in part outside Switzerland. The transfer is based on the standard contractual clauses recognised by the Federal Data Protection and Information Commissioner, together with the data-processing agreements concluded with these providers.
