Paid Code Card plans are managed from the Billing page.
When production billing is enabled, checkout and subscription management are hosted by Stripe. Code Card Library does not collect card numbers in its own forms.
The Billing page can show your current subscription, subscription status, the current billing period end, whether cancellation is scheduled, and available monthly or yearly plans.
Selecting Manage billing opens Stripe's hosted billing management experience.
Paid features are activated only after Code Card receives an authenticated billing update confirming the subscription state. Cancellation or subscription failure updates the associated account entitlement.
Production checkout remains unavailable until the live Stripe configuration and controlled production payment testing are complete.
