Hi,
That VPN trial will not have automatic renewal and if you haven't registered any payment information, then the license cannot be renewed automatically in the first place.
VPN connections I have a trial version of your product but I can't use a VPN connection all the time. My traffic is limited. If that's the case even after I buy the product, it's not worth it.
All trial versions ask for a credit card, and say that you can cancel before the trail is over. But I don't seem to be able to cancel, I just get emails that tell me to keep it....
