Cookie Policy
Last updated: February 2026
We use cookies and similar technologies to provide the service, remember your preferences, and—with your consent—to analyse usage.
Strictly necessary
Session cookies (e.g. authjs.session-token) for authentication; bfh_invite_token for invite flows. These are required for the site to function.
Functional / preferences
locale (language), sidebar_state (sidebar open/closed), chat-model (selected chat model). These improve your experience; you can refuse them via "Essential only" in the cookie banner.
Analytics
We use Vercel Analytics (cookieless) only if you choose "Accept all". It provides aggregated usage data and does not identify you personally.
Consent cookie
cookie_consent stores your cookie choice (e.g. essential_only or all) so we do not ask again until it expires or you change preferences.
Changing your preferences
You can change your cookie choice at any time via "Cookie preferences" in the footer or in the app Settings. Your choice is stored in the cookie_consent cookie.
