What is stored in the browser?
Choosing a language stores the selected locale under selee-tv-locale so later navigation can preserve that choice. The homepage also uses the session-only selee-tv-locale-detected flag to avoid repeating automatic browser-language routing. When GA4 is enabled, Google may set analytics cookies or use similar identifiers according to the deployed property's settings and Google's policies. Canvas stores non-secret Canvas and session identifiers, draft text, and event replay offsets per Canvas so interrupted workspaces can recover. A signed-in session uses a host-only, HttpOnly, Secure, SameSite=Lax cookie; the account token is not exposed to JavaScript storage.
