The Vault holds personal, sometimes sensitive information about the people in your life. Here is exactly how that is handled, including by the AI assistant.
Every request is checked against your account before anything is read or written. Your contacts, notes, and reminders are never visible to another account.
Google Contacts/Calendar access and your Apple app-specific password are only ever requested if you choose to connect them, and the credentials are encrypted at rest, the same standard applied to any other sensitive access token. Disconnecting revokes access immediately.
The assistant reads and writes through the same per-account access rules as the rest of the app. It cannot reference or imply access to anyone else's data.
When Ask Vault proposes a change, such as a new reminder or a logged interaction, it shows you exactly what it plans to save first. Nothing is written until you approve it.
When you use Ask Vault, the relevant contact details for your request (names, notes, dates, and similar) are sent to Anthropic's Claude API to generate the response, governed by Anthropic's own data-handling terms. Nothing is sent unless you actively use the assistant.
