Legal notice and privacy

Who runs this site#

This is the personal website of Elon Salfati, based in Zürich, Switzerland. It sells nothing and has no advertising.

To reach me, send a message on LinkedIn. That is also the contact for anything on this page, including privacy requests.

Views here are my own. They are not the views of Imperial College London, Salfati Group, or any company I work or have worked with.

Privacy#

The short version: no cookies, no ads, no forms and no tracking across sites. Three things touch your data.

Hosting#

Vercel Inc. hosts the site. To send you a page, its servers process your IP address, the address you asked for, your browser's user agent and the time. Vercel handles this on my behalf, to deliver the site and protect it from abuse. Vercel is a US company and is certified under the Data Privacy Framework, which covers transfers from the EU, the UK and Switzerland to the US.

Visitor statistics#

I count visits with Plausible Analytics, run by Plausible Insights OÜ, an Estonian company that keeps its data in the EU. Plausible sets no cookies and stores nothing on your device. It never stores your IP address or user agent. To tell visits apart for one day, it hashes them with a random value that is deleted every 24 hours, so a visit can't be linked to you or to another day.

What I see is aggregate: which pages are read, which site sent the visit, which outbound links are clicked, and the browser, operating system, device type and country.

Videos#

Pages with a YouTube video show its preview image from YouTube's image server. The player itself comes from youtube-nocookie.com and loads only when you press play. From then on, Google's privacy policy applies.

On your device#

If you switch between light and dark mode, your browser remembers the choice under the key theme. It never leaves your device.

Your rights#

The legal basis is my legitimate interest in running a secure site and knowing which pages people read (GDPR Art. 6(1)(f); the Swiss Federal Act on Data Protection needs no consent for this). You can ask what data about you exists, and have it corrected or deleted. I keep no data that identifies you myself; for hosting logs, I will pass your request to Vercel. You can also complain to the Swiss Federal Data Protection and Information Commissioner or, in the EU, to the data protection authority in your country.

How this site is written#

I write and build this site with AI tools, including Claude. I choose the topics, check the facts and edit every page before it goes live, and I am responsible for what it says. Some reference pages, such as this one, are drafted and kept current by an AI agent; I review each change before it is published.

The diagrams are drawn from code in the style of a whiteboard, the animations are rendered with Manim, and the portrait is made from a photograph of me.

Links and reuse#

Links to other sites are there because they are useful. I don't control them and I am not responsible for what they say.
