When installing that program, it also installs an ESO addon. Each person in your guild can use that addon to upload their data to a website, dropbox, whatever. The application is to compile everyone's data for you to view. But I don't think you need to use the application, if you want to use some other way to compile the data for viewing... But I'm not sure... It may format the data in such a way for the application to read it. /shrug
Our guild just uses an addon to generate the trait/research information, and then uploads the SV to a custom built website to collate and render that information.
