Security & control
Local by default. Approved by you.
Your data stays on your Mac, your secrets stay in the Keychain, and destructive actions wait for your yes.
Keys, data,
and consent.
The promise matches the implementation. Secrets live in the macOS Keychain, app state persists locally as JSON, approval gates hold destructive tool calls, and sign-in only establishes identity.
Keychain
API keys, provider secrets, refresh tokens, and integration keys live in the macOS Keychain.
Local App Data
Profiles, memory, sessions, activity, schedules, workflows, and framework state persist locally as JSON.
Approval Gates
Destructive direct tool calls are held for user confirmation unless explicitly pre-approved.
Account Boundary
Firebase Google sign-in verifies identity and Supabase returns trial/plan state.
