Cookie Policy
Last updated: June 7, 2026
🔒 No Cookies on Classroom Pages
Read-only classroom pages, the web addresses that begin with /c/, set no cookies and load no analytics, performance, or error-tracking technologies of any kind. The optional PostHog, Vercel, and Sentry tools described below are never injected on these pages. This is enforced in the application itself, not by a consent prompt, so a student viewing a class code is never tracked, fingerprinted, or measured. It reflects our broader commitment to collect no student data, ever.
