What cookies are
Cookies are small text files that a website stores in your browser. Websites also use local storage — a similar mechanism with a larger capacity and no automatic expiry. Both are used to remember information between page loads or visits. Neither can run code or access files on your device.
Essential cookies we use
RinkHQ uses Supabase for authentication. When you sign in, Supabase sets cookies and/or uses browser local storage to maintain your session. These are strictly necessary for the application to function — without them you cannot stay logged in.
Name / prefixPurposeExpires
sb-*-auth-tokenStores your authentication session so you remain logged in across page loads.Session / up to 1 week
sb-*-auth-token-code-verifierPKCE verifier used during the OAuth / email sign-in flow. Removed after sign-in completes.Short-lived (minutes)
The exact cookie names include your Supabase project reference, so they look like sb-[ref]-auth-token. Their purpose is the same regardless of the reference.
No advertising or tracking
RinkHQ does not use third-party advertising cookies, tracking pixels, or analytics services that set cookies in your browser. There is no Google Analytics, Facebook pixel, or equivalent tool on this site.
We do not share cookie data with advertising networks. We do not build behavioural profiles of our users.
Managing cookies
You can clear cookies and local storage at any time using your browser’s privacy or developer settings. Doing so will sign you out of RinkHQ — you’ll need to sign in again on your next visit.
Because the only cookies we set are essential to the service, blocking them in your browser means you will not be able to use the authenticated parts of RinkHQ (booking, coach dashboard, parent account).
