When you publish a project with Articulate 360 for the web or an LMS/LRS, the program creates a set of files. Those files can be uploaded to wherever you want to share them. They belong to you.
You can also publish to Review 360 and share links to projects there. But that access is cut off when the trial period ends. (As I understand it, Articulate keeps your Rise courses and Review projects for 6 months after a trial period or license ends. You won't have access to them, but they aren't permanently deleted right away. So if you do subscribe within 6 months, you'll be able to access them again.)
