Privacy

Last updated: 15 November 2026

This page explains what personal data thebrainprimer.com collects, why, and what you can do about it. For anything about your data, write to [email protected].

Reading the site

The site sets no cookies and has no advertising, and nothing on it identifies you or follows you around the web. It is hosted by Cloudflare, which handles technical data such as your IP address and browser type to deliver pages and protect the site from attacks. We count visits with Cloudflare Web Analytics, which uses no cookies and does not identify you.

On articles, a small script counts how far down the page readers get (a quarter, half, three quarters, the end), so we can see where a story loses people. It sends only the article’s address and that mark: no cookie, nothing stored on your device, and nothing that identifies you or links one visit to another.

Your language choice

If you choose a language with the switcher at the top of the page, your browser remembers that choice on your own device (in its local storage), so the home page opens in your language next time. It is never sent to us. Clearing this site’s data in your browser removes it.

The newsletter

If you subscribe, we collect your email address and the language you signed up in, with your consent, to send you our emails. They are stored by Kit (kit.com, based in the United States), our newsletter service, which records whether an email is opened and which links are clicked, so we can see what readers find useful. Every email has a one-click unsubscribe link, and you can also ask us to delete your details at any time. The newsletter is for adults: if you are under 18, please do not sign up.

Films on the site

Articles show a still image of their film, loaded from YouTube’s image server. The film itself loads from youtube-nocookie.com only when you press play, and from then on YouTube’s own privacy policy applies.

Emails you send us

If you write to us, we keep your message and address to reply, and for as long as the conversation needs.

Your rights

Wherever you live, you can ask to see the personal data we hold about you, to correct it or to delete it, and you can withdraw your consent at any time, which stops future emails. You can also name someone to exercise these rights for you. If you live in the European Union or the United Kingdom, you have the rights the GDPR gives you.

Questions and complaints

Write to [email protected] with “Privacy” in the subject line. We reply as soon as we can, and within 90 days at the latest. If you are not satisfied with our answer, you can complain to the data protection authority where you live: your national authority in the European Union or the United Kingdom, or the Data Protection Board of India.
