Two quick questons before I upgrade to Pro..

Hi, quite like the theme and subject to a customer of mine approving the style and layout of it I am looking to upgrade. I have two questions however.

1. Am I allowed to use the them for commercial use, i.e, i make a site for someone using this them and charge them money.

2. Is it possible to switch the “responsive” aspect on and off so mobile and tablet versions are just basic desktop sites? (If so, how?)

Cheers in advance!
