What happens next

Cancelling takes effect at the end of your current billing period, and you keep access until then.
Nothing is deleted. Your drafts, voice and settings stay saved, and features that need a plan pause until you pick one again.
Pausing is not available. You can cancel and subscribe again whenever you are ready.
