I paid but my credits aren't showing
Credits are added the moment Stripe confirms your payment, which is normally within moments of checkout completing. When that happens, the app shows "Payment received. Your credits are being added to your balance."
If your balance has not moved
Refresh the page first. The balance in the header reads from your account record, and a refresh pulls the current number.
If the credits are still missing after a few minutes, contact support through the chat widget. Include the email you used at checkout and roughly when you paid. Every purchase is recorded, so a delayed one is found and credited. You will not lose a payment that went through.
If the payment did not complete
A checkout that was closed before finishing, or a card that declined, grants nothing and charges nothing. There is no partial state to untangle. Simply start the purchase again.
The structure here is deliberate. Credits are only granted against a confirmed payment, and every confirmed payment is recorded against your account. That is what makes your balance dependable: it always reflects exactly what has been paid for, no more and no less.
