Nothing to leak.
A request for your conversations has nowhere to land. There is no central party to ask.
No email, no phoneYou sign in with a passkey. No password, no name, no card on file.
No chat history on a serverConversations stay encrypted on your device. Nothing syncs anywhere unless you choose to.
No profile of what you askPrompts are encrypted before they leave your device. Nobody in the middle can read them, so nobody can build on them.
Who sees what
Blind is the default.
Every exposure is deliberate and bounded. No party gets two columns.
