When a parent signs in

Signing in to the Opblox app sets a few cookies. They are strictly necessary to keep you signed in safely, so there is nothing to accept or decline.

• __session on opblox.com: a short-lived sign-in token that proves you are signed in.
• __client_uat on opblox.com: tells the app when you last signed in or out.
• __client on clerk.opblox.com: kept by Clerk, our sign-in provider, to keep your session secure.

Once you have signed in, your browser also sends __client_uat to other pages on opblox.com. Those pages still set no cookies of their own and do not use it.

We use no analytics, advertising or tracking cookies. Children never sign in through Clerk.
