In short
- This website is a single information page. It has no forms, no account and no newsletter.
- It sets no cookies and stores nothing in your browser, so there is no consent banner.
- It loads nothing from other servers: fonts and images are served from this site itself. There is no analytics, no advertising and no social media plug-in.
- We do not sell personal data.
Visiting this website
When you open a page, your browser sends the hosting provider the technical data every web request carries: your IP address, the date and time, the page requested, the referring page, your browser and operating system, and the response status. The hosting provider processes this data on our behalf to deliver the site and to protect it against attacks. We do not combine it with other data and do not use it to identify you.
- Hosting provider
- Cloudflare, Inc. (USA)
- Legal basis
- Legitimate interest in delivering and securing the website (Art. 6(1)(f) GDPR)
- Retention
- We receive and keep none of these logs ourselves. The hosting provider keeps them only as long as it needs them to deliver and protect the site, as set out in its own privacy policy, and then deletes them.
Writing to us
If you e-mail us, we process your address, your message and any data you include, only to answer you. We delete the correspondence when it is settled, unless the law requires us to keep it longer. Our e-mail is hosted by Infomaniak Network SA in Switzerland, which processes it on our behalf.
- Legal basis
- Legitimate interest in answering enquiries; steps prior to a contract where you ask about one (Art. 6(1)(f) and (b) GDPR)
Transfers abroad
The hosting provider is a company in the USA and delivers this site from data centres worldwide, so request data can be processed outside Switzerland and the EU. It is certified under the EU-U.S. and Swiss-U.S. Data Privacy Frameworks and is bound by the standard contractual clauses in its data processing agreement.
Your rights
You can ask us at any time what data we hold about you, and have it corrected, deleted, restricted or handed over to you. You can object to processing based on our legitimate interest. Write to the e-mail address above.
You also have the right to complain to a data protection authority: in Switzerland the Federal Data Protection and Information Commissioner (FDPIC) (www.edoeb.admin.ch), and in the EU the authority where you live or work.
