Cookies help keep you signed in. Choose whether this browser should remember you for longer at your next sign-in.

01 / COOKIE SETTINGS

Keep it simple.

Essential sign-in cookie Required

__Host-gc_sid (gc_sid on a local test copy) is the server-issued cookie that identifies your signed-in session. It is HttpOnly, so page scripts cannot read it. Sign-out removes it and ends that session.

Without remembering, sign-in uses a session cookie with a 12-hour server limit. Use Sign out on shared devices; closing a tab is not a reliable sign-out.

Remember this deviceOptional · up to 30 days

Select this to preselect remembering on your next sign-in. You can change the checkbox there. After you sign in with remembering selected, the server gives that device a longer-lasting sign-in cookie.

This setting does not extend, shorten, or sign out an existing session.

Optional remembering is off until you choose it.

“Accept all” currently means only remembering this device. It does not enable analytics, advertising, or trading.

02 / GOOD TO KNOW

Same account.
Different devices.

Your portfolio and approved wallets are saved to your account on the server—not inside these cookies. Sign in to the same account on your phone or computer to see them.

This preference is saved in this browser’s local storage. It contains only a yes/no remembering choice and a format version, never your email, password, API keys, or session token. It does not apply to other devices.

Session expiry, signing out, clearing browser data, or an owner access change may require you to sign in again. Remembering does not bypass owner approval or Terms acceptance.
