Cookie policy
Effective 12 November 2026
Brier uses as little browser storage as it can: a cookie to keep you signed in, one to remember your choice, and, only if you allow it, your watchlist on this device. No analytics, no advertising, no third-party cookies.
What cookies are
Cookies are small files a website stores in your browser. Local and session storage are similar browser features. This policy covers all of them.
