As we don't run lock in hosting contracts, we therefore do not require any credit card details to be stored anywhere. When you activate your keyring, you automatically get 12 months hosting, from that day and after that time is up, your account will show a pop up asking for prepayment for the next 12 months, with a credit card option. Enter your card details and our payment gateway provider will take care of the rest, through their security firewalls, so we never see or handle any of your CC details. We currently use Stripe to do this part
www.stripe.com as do Google, Uber and Spotify, to name a few. Our current hosting fee paid 12 months in advance is set at 50p/A$1 a month.
