Quick answers

Do I need a credit card?

No. Guest chat and the free plan never ask for a card. A card is only needed if you choose to start the Pro trial or subscribe.

Is Nox a doctor?

No. Nox is an AI health advisor — it explains, informs, and helps you prepare for care, but it never diagnoses or prescribes, and it always points you to professionals when that's the right move.

What happens to what I type?

Guest conversations are never saved. With an account, your chats are private, are not sold, and you can delete conversations — or use Incognito mode for chats that are never stored.
