I'd say there's not anything to even judge if it's not just a way to charge a credit card. Picking a plan asks for a web address (which isn't validated in any way, you can type a single letter), and then it shows what looks like a Stripe CC popup (which probably signs a user up for recurring billing on stripe). Nothing about a login, email or password (I can ASSUME that's after a card is entered, but who knows..). I would never use something like this in its current state.
