In normal operation, they stay until removed by archiving (only done by the desktop version) or deleting. Or pressing the "Reset Database" button, but you probably don't want to do that :)
Whether you see them or not depends on your settings for which actions/projects are shown. By default, the iPhone app doesn't show completed actions and projects, but it is possible to configure the project views to show completed items.
