You own what you purchased. What you get with your purchase is one year of any updates to the included OD ULT programs. There is an archive feature built-in Impulse which allows you to backup your Stardock programs and restore them whenever you wish.
None of the Object Desktop programs you purchased will shut down after your 1 year expires even if you don't re-subscribe. They all will work.
If someone fails to archive (backup) their programs then their only option would be to make a request to Stardock support for the last version they were entitled to.
