Common questions
Where does my code run? In a private cloud machine reserved for you — never on our shared servers.
Do I need an AI subscription? Yes — agents run on your own Claude or ChatGPT/Codex account or API key.
How do I cancel Stell Pro? iPhone Settings → your name → Subscriptions → Stell Pro.
How do I delete my account? In the app: Settings → Delete account. This destroys your sandbox and its data.
