Number of sites allowed with one purchase

I would like to purchase Graphy Pro, but want to use it for two completely different personal websites. Is this allowed or would I have to purchase two separate copies of the theme? (i.e. It would cost double). If it is allowed to use it more than once, then what is the best way of downloading it / uploading it to the second site? I cannot find any details about the actual terms of the license you are purchasing when you buy Graphy Pro.

Appologies, but somehow I managed to ask this question under the ‘Reviews’ section the first time around(??) and now don’t know how to remove it from there!!
