Yes, as long as you remain subscribed and don't cancel your Brizy subscription plan you'll have Brizy Cloud included.
Brizy Cloud is a different product from Brizy WordPress plugin and it is possible it will be priced and sold separately in the future.
It is hard to predict what will happen in the future and most likely we'll make price changes to our products, but any price change we will operate will apply going forward for new clients and will not affect you if you already have an active subscription to our services.
