Update your card
Settings → Billing → Manage subscription. Add or replace the card used for your subscription.
Invoices
Every charge produces an invoice you can view and download from the same place.
If a payment fails
We email you and retry. Update the card promptly — after repeated failures your access is limited until the balance is settled. Your data is not deleted.
Two different things
This card pays for OperMae. It is unrelated to the Stripe account that receives your customers' payments.
