The program itself belongs to SOPHIA XT LLC. It isn't open source: you may not sell or repackage the program, change the program file, or take it apart.

What you make with it is yours: your content, your data, and the extensions, templates and sites you build. You may sell those. Sophia Stack X doesn't send your content or data to SOPHIA XT. It contacts the download site only when you ask it to check for an update.
