I paid but do not have access. What should I do?

Sign in to the same Calsa account used for the purchase and check You → Subscription. For a store purchase, use Restore purchases with the buying store account. Keep the receipt or order reference so the purchase can be checked.

A pending or missing confirmation does not mean you need to pay again. Calsa checks the billing result before opening access. If it remains missing after restoration, contact support with the billing service, purchase reference, approximate time and the status shown. Do not include full card details, sign-in codes or your diary.
