Without sign-in, everything lives only in chrome.storage.local on your device. • Cloud sync is opt-in. Only enabled when you sign in with Google. We use Supabase (industry-standard backend) and OAuth via PKCE — the same flow used by Google for trusted apps. • No tracking, no analytics, no ads. We don't sell, share, or analyze your data. • No remote code injection. The extension only runs JavaScript bundled inside its package — Chrome itself enforces this on all Manifest V3 extensions.
