Use typhoons license key for one domain and later for another domain

I am thinking about buying the premium typhoon theme. There is this „license key for 1 site“ note. Currently I am developing my website on a domain dev.domainA.com, later in like 2 weeks I want to use this (only) on my productive domain which is domainB.com. Is this possible or is the key „burned“ with the other domain? What is the correct way to use this theme a couple of weeks on a domain and after that on a completely different domain?
