Yes. Nothing leaves your space, and connected sources are only ever read-only, for you alone — never to train a public model. You can export everything (Markdown, JSON) or delete it at any time.

Anytime, no commitment. The switch is immediate and prorata is calculated automatically. The monthly quota is monetary: you see what you spend, no nasty surprises.

Web, desktop (macOS, Windows) and mobile (iOS, Android). The same thread, synced everywhere — focus mode and keyboard shortcuts (⌘K, ⌘N) carry over on every platform.
