Credit card info is only required for the second app launch, or when you invite more than two people. We have to do that to manage our resources, but we definitely didn't want it to be the first thing you see. If you send me your account email , I'll bump you to a verified account manually so you don't hit that :)

Edit: You can send it at sean@cloudfuji.com or just click on the support link in-app, and you'll get a modal form to contact us.
