Card details are held by Stripe, not Mintlytics — we don't store them. To update:
- Go to /settings → Billing.
- Click Manage subscription.
- In the Stripe portal, scroll to Payment methods and click Add payment method or remove an existing one.
- Set the new card as default.
Next billing cycle uses the default card. If the new card fails, Stripe retries for 7 days before suspending your plan and emailing you.
