Vault
Your travel profile, your payment card and the logins your yōkai can use on its own. None of it is ever shown to your yōkai. Passwords and passport details are sealed on your device first, and your card stays with AgentCard.
Travel profile
Your name exactly as on your passport, date of birth and passport details, so your yōkai can book flights for you. Sealed on this device before it is sent. Your yōkai types it straight into the airline's form and never sees it, and it never comes back to this page.
Payment card
The card your yōkai pays with. You type it on AgentCard's own page, never here and never in a chat, and it is saved with your passkey. Each purchase you approve gets a one-time card for exactly that amount, typed into the checkout without your yōkai seeing it.
