Thanks for bringing it up - we should really make it more consistant.

Permanent, in this case is Unlimited. Perhaps permanent is the correct terms, since it's only "unlimited time", not unlimited domains, for example.

Permanent license doesn't include mobile apps re-branding license or installation, but you may purchase them separately and add to your order. Not affected by pricing changes - this is simply implied from the fact that it is permanent, therefore you wouldn't have to see more bother if the license price ever goes up again.
