Privacy policy
In short: this site sets no cookies and uses no trackers and no analytics. It asks you for no data. That is why there is no cookie banner: there is nothing to accept.
What this site does not do
- No cookies, neither ours nor anyone else's.
- No analytics or audience measurement.
- No “Like” buttons or social media widgets loaded in the page.
- No advertising, no forms, no accounts.
- Nothing is stored in your browser.
- The fonts are hosted on this site: no request is sent to Google or any other service.
Hosting
To show the pages, the site's host, OVH SAS (Roubaix, France), necessarily receives your device's internet (IP) address, as with any website. It may keep it briefly in its security logs, under its own policy. The publisher does not use these logs.
YouTube videos
No YouTube video loads when you open the site. A video only plays if you click it. It then comes from youtube-nocookie.com, YouTube's privacy-enhanced mode, and YouTube (Google) may receive data under its own policy. Until you click, nothing is sent to YouTube.
Links to other sites
The buttons to Amazon, YouTube, Facebook, Instagram and TikTok take you off this site. Their own privacy rules then apply.
If you write to the professor
If you send an e-mail, your address and message are used only to reply to you. They are never sold or passed on, and they are deleted when the exchange is over, or sooner if you ask.
Your rights
You can ask to access, correct or delete data about you by writing to contact@archibaldzero.com. You can also complain to the French data protection authority, the CNIL (cnil.fr).
