You could always ask on their Discord as the dev(s?) will answer questions, but my best guess is that it is a more old-school approach where the key is something that works offline.But does it still require you to be always online and do a profile check?
Personally I've not used it since the trial I had some years back, as I don't need the additional functionality. I've always kept it in mind though, and if I didn't have what I needed from DS4W and SteamInput I'd definitely have spent the money.
