You can only use the free FlashEff version offline. For the premium full version to work, you need to be logged in, so you'll need an internet connection. In this case, you won't be able to use the FlashEff panel but you'll be able to use the FlashEff component and FlashEff patterns by code without any problem.

So, Free version -- FlashEff panel works offline
Premium version -- FlashEff panel does not work offline, but the component and patterns still can be used by code, without panel.
