if you're logged in here, you're logged in there, the same applies to premium. Premium services on allakhazam.com currently, and as far as all plans go, always extend to include all new features and sites that we launch. We're very appreciative of the people who sign up for premium services with us, and never want to try to nickle and dime people by saying "gee we know you already paid, pay us more". If you're premium here, it covers lucy as well.
I purchesed an advanced lucy account just before the switch
I'm not sure what you mean by that. Lucy didn't offer accounts previously, nor did it offer the ability to buy anything.
