Privacy Policy
We collect as little as possible.
What we collect
Every site in this network is a static educational site. We do not ask you to create an account or submit personal information to read content. There are no sign-up forms. Where a site offers a calculator, it runs entirely in your browser and sends nothing to any server.
Analytics
We use privacy-friendly, aggregate analytics — Cloudflare Web Analytics, Google Analytics and Microsoft Clarity — to understand which pages are useful. These collect anonymised, aggregate usage data and do not identify you personally. IP anonymisation is enabled.
Cookies & storage
We use minimal browser storage — for example, remembering your light/dark theme choice. We do not sell personal data, and we run no advertising or retargeting.
Third parties
Content is served via Cloudflare, whose processing is governed by their own privacy terms. External links open third-party sites with their own policies.
