Cookie Notice

Sign-in cookie (set by Supabase, our sign-in service): keeps you signed in, as a guest or with your email. It's only set once you open the app itself; the public pages set no cookies.

Account-saving cookie (cs_merge_from): when a guest asks for a sign-in link, it remembers which guest account to move into your account once you click the link. It lasts one hour and is deleted when you sign in.

Robot check (Cloudflare Turnstile): when it's switched on, it runs only on email sign-in and may set short-lived cookies on Cloudflare's own site to tell people from scripts.

The last school you typed, the classes for quick hint capture, which tips you've already seen, and hints saved while you were offline.

Which study rounds you've finished for each exam (saved as cs.rounds. plus the exam's id), so free study picks up where you left off.

Which exam reminders you hid (saved as cs.reportBanner. plus the exam's id), so a hidden "How did it go?" reminder stays hidden.

Which parts of the app this browser has already reached, like your first ranked list (saved as cs.found. plus the feature's name). It only stops us counting the same first visit twice.

Signing out or deleting everything clears all of these.

Your Reduce motion and keyboard shortcut settings. These stay after you sign out, because they're settings for this device.

A copy of the app and of recent pages, so it opens offline. Signing out clears the page copies.

Vercel Web Analytics counts page views without cookies. Vercel says it tells visits apart with a scrambled code made from each request, which it throws away after 24 hours. Before a page address is sent, we remove class and exam ids and anything after a "?".

If your browser sends Global Privacy Control, it sends us no page-view counts at all.

Everything above is needed for the app to work, is a setting you chose, or is counted without storing anything on your device. If we ever add something that needs your permission (ads, social media embeds, session recording), we'll ask first, with saying no as easy as saying yes, and update this page.
