Privacy Policy

Last updated: September 2026

The short version

This site currently runs no advertising, no analytics, and no tracking cookies. The only thing stored in your browser is your light/dark theme preference, saved locally on your own device — it's never sent to us or anyone else.

What we store locally on your device

We use your browser's localStorage to remember your theme choice (light or dark) between visits. This stays on your device; we have no way to read it, and it's never transmitted anywhere.

Server logs

Like virtually every website, our hosting provider automatically logs basic request information (IP address, requested page, browser type, timestamp) for security and operational purposes — this is standard web server behavior, not something we actively analyze or use to identify individual visitors.

Advertising (not yet active)

We intend to run Google AdSense once the site has steady traffic. When that happens, this policy will be updated, and a Google-certified consent management platform will be added so visitors — especially those in the EEA and UK — are asked for consent before any advertising or measurement cookies are set. Once active, Google and its partners may use cookies to serve ads based on your prior visits to this or other websites; you can review and opt out of personalized advertising via Google's Ad Settings and learn more at Google's advertising policy page.

Children's privacy

This site is educational reference material that students of any age may use for schoolwork. We don't knowingly collect personal information from anyone, including children, and the site doesn't require an account, login, or any personal information to use.

Changes to this policy

If our practices change — most notably when advertising goes live — we'll update this page and the "last updated" date above.
