No. The single-machine plan stays at $0 forever, your credentials stay with you, and the daemon code lives on your machine.
When does billing start?
Bills stay waived until billing opens, with at least thirty days' email notice first.
When do I need Pro?
Local is enough for an agent on one working machine with one vault. Pro is for the second machine: your vault syncs through a zero-knowledge cloud and follows you.
How does my team start?
Create a shared vault in the console: a 30-day free trial, no card, invite your members, and people and agents share one set of credentials. Audit attributes to person, agent, and device; after the trial it bills per seat.
