Cookies
HEADING sets a small number of cookies and browser-storage items to run the service and, only with your permission, to understand product usage. This page lists every service we use, grouped by category, why it's there, and for how long.
Strictly necessary
Required to run HEADING — signing in, security, and remembering your cookie choice. These can't be switched off.

No client-side storage | Sentry | Reports application errors so we can fix bugs — runs server-side only, sets no cookies or browser storage.
