The Freehold licence

Every version you've paid for is yours to keep.

Stop paying and nothing stops working: the agents you have keep running, for good.
Any release published while you paid stays downloadable, on any of your PCs: reinstall after a reset, or set up a new one.
Releases published after that wait until you subscribe again, and then you catch up at once.
Moving from Workshop to Household keeps the developer agents you have, at their versions.
The 7-day trial is the one exception: when it ends, its agents rest, with their settings kept, until a licence wakes them.
