Browser preferences & sign-in
The marketing site stores language and theme preferences in browser storage and a presentation cookie. Sign-in is handled by the account app, which keeps authentication cookies on its own subdomain. The marketing header asks that app only whether you are signed in.
Accounts, payments & AI providers
Firstbeam account, device, subscription and payment services process the information needed for those services. AI requests use your selected provider; its own data and billing policies apply to the context you send.
Desktop projects & account deletion
Desktop project conversations, plans and notes are stored locally. The browser demo uses fictional sample transcripts and does not run provider agents. Account deletion requests can be sent to support; browser logout does not remove local desktop files.
