Privacy policy

Last updated 30 October 2026

This website has no cookies, no analytics and no accounts.

Who is responsible

Mohamed Bechir Kefi (“I”) is responsible for this website. You can reach me at kefimohamedbechir@gmail.com. See also the legal notice.

This website

The site sets no cookies and stores nothing in your browser. It has no analytics, advertising, tracking pixels, contact forms or sign-ups.

Its fonts, scripts, images and videos all come from this site, so your browser does not contact any other company to show it.

The 3D table runs entirely in your browser. Where your pointer is and how far you scroll are used on your device to draw the page, and are never sent anywhere.

Links to other sites

The site links to the research report and code on GitHub. Your browser contacts GitHub only if you follow one of those links, and GitHub's own privacy policy applies from there.

Server logs

As with any website, your browser sends your IP address, browser type and the page you asked for when it connects. The company that hosts this site may record these in technical logs to deliver the site and keep it secure.

The legal basis is the legitimate interest in running a secure website (Article 6(1)(f) of the GDPR). I do not use these logs to identify or profile visitors.

If you write to me

I receive your email address and whatever you include in your message. I use them only to answer you, and keep them only as long as that takes or as the law requires. The legal basis is my legitimate interest in answering you, or the steps needed for a request you make.

Your rights

Under the GDPR and similar laws, you can ask to access, correct or erase your personal data, restrict or object to its use, and receive a copy of it. Write to kefimohamedbechir@gmail.com. You can also complain to your data protection authority.

No decisions about you are made automatically, and your data is not sold.

Changes

If this policy changes, this page and its date change with it.
