What an assistant never does

The boundary around every conversation: no silent activation, no calendar CRUD, no billing, no AI at execution time.

No custom rule is switched on without you doing it on Heldrey’s page.
Nothing else that deletes, takes a slot, pauses, or resumes is confirmed without your word in the conversation.
Preview never writes to your calendar.
No assistant moves, cancels, or replies to an event, or contacts an attendee.
No AI runs when a rule executes.
An assistant never sees your billing details.
Text from your calendar is treated as data, never as instructions.
An assistant cannot finish team management, account merge, account deletion, or payment.
An assistant cannot pick which rules stay on after you go over the allowance. That choice stays in the app.
