Privacy policy

Last updated 1 November 2026

The short version: PhysEduc has no accounts, no ads and no tracking. Your progress stays in your own browser.

What we don’t collect

You never give us your name, email address or any other personal details to use PhysEduc. There are no accounts, no advertising, no analytics or tracking scripts, and no cookies.

Your progress, on your device

To remember which slides you have seen, your last lesson and your settings (such as captions and the light or dark theme), PhysEduc uses your browser’s local storage. This stays on your device and is never sent to us. You can delete it with Reset my progress on the home page, or by clearing your browser’s data for this site.

Services that deliver the site

• Cloudflare hosts PhysEduc and delivers its pages and videos. Like any web server, it receives your IP address and basic details of each request (such as the page asked for and your browser type) to deliver the site and protect it from attacks. We see these technical logs only to fix problems, and they are kept for a few days. See Cloudflare’s privacy policy.
• Google Fonts supplies the site’s typefaces, so your browser fetches them from Google, which receives your IP address. See Google’s privacy policy.

If you email us

If you write to us, we use your email address and message only to reply, and we don’t share them with anyone.

Children

PhysEduc is made for school students. Because it collects no personal information, it can be used without sharing anything about the student.

Changes

If this policy changes, we will update this page and the date at the top.
