• Local preferences: theme or UI choices stored in your browser where applicable.

Analytics (Vercel)

In production we use Vercel Web Analytics to collect aggregated usage metrics. These technologies help us understand which pages are useful and whether the site performs well. See Vercel's documentation for details on what they process.

Advertising (Google AdSense)

We load the Google AdSense script on pages so Google can verify the property, serve ads where enabled, and measure delivery. In the EEA, UK, or Switzerland, Google may also show its consent platform (CMP) to collect ad-related choices. Google and its partners may set cookies or use similar storage for these purposes, including personalized ads where allowed by law. Details: policies.google.com/technologies/ads.

Third-party links

Our educational pages may link to third-party websites. Those sites have their own cookie practices, which we do not control.
