When your Mattermix account is created you will automatically be signed up for a Mattermix Subscription without needing to provide any credit card information. The only time you would need to include your credit card information is when you increase your API limit beyond 50 monthly exports.
If your subscription is canceled you'll need to create a new subscription from the Subscription Dashboard by clicking on the Subscribe button. This will redirect you to Stripe Checkout where you can enter your information and subscribe.

You can view your current and previous subscription from the Subscription Dashboard by clicking on the Manage button. This will redirect you to the Stripe Customer Portal where you can view and update your payment method, billing information, and invoice history.
