No tracking. Your data stays with you.

• No tracking cookies, no audience measurement, no advertising.
• Fonts, maps, videos and search are served by the site itself: your browsing is not passed to any third party.
• A few preferences are stored in your browser only; they are never sent to us.

The site uses your browser’s local storage (localStorage) for four purposes, all optional:

Language

Your choice of language (cs-lang), so the site opens in that language next time.

Reading comfort

Reduced motion, text size and contrast (cs-motion, cs-text, cs-contrast).

Reading progress

How much of each white-paper chapter you have read (cs-read), shown on the spines in the library.

Message draft

The text typed into the contact form (cs-enquiry-draft), kept on your device while online sending is unavailable, so that you do not lose it.

You can clear these data at any time from your browser settings (site data). In a private window they disappear when you close it.

Site search runs entirely in your browser, from an index downloaded with the pages: your queries are not sent to any server.

Online sending of the contact form is not yet active: the site tells you so clearly and transmits nothing. A contact address will be published as soon as it is in service; until then you can write to the postal address of the registered office. The information you send us is used only to answer your enquiry and follow it up; it is neither sold nor passed on.

Like any website, the host may keep technical logs (IP address, date, page requested) for security and to keep the service running. The host is Vercel Inc. (United States); these logs are kept for the period set out in its privacy policy (see the legal notice).

In accordance with the Cameroonian legislation applicable to personal-data protection, you may ask for access to any information about you that we hold, for its correction or deletion, and object to its use. Send your request through the contact form.
