Payments and Refunds
Content approved on 1 October 2026
Before you pay
Check the plan name, duration, currency, discounted price and the amount to transfer. Yearly plans show the total for the whole year. Anything an AI platform charges separately is not part of the Mark Flow fee.
Bank transfer and activation
Use the exact transfer code of the order and the amount shown. Activation happens after the transaction is confirmed, automatically or manually depending on configuration. Do not send extra money as a test while the status has not updated; check the order and contact support.
PayPal subscriptions
PayPal plans are charged in USD and renew automatically each month or year. The fee is shown before you approve the subscription on PayPal; discount codes, affiliate credit and VietQR upgrade credit do not apply yet. In the Mark Flow account menu, choose Manage billing · PayPal to see the status and cancel renewal. A successful cancellation keeps your access until the end of the verified paid period; removing the extension does not cancel the subscription. Refund requests are handled under the policy below.
Polar subscriptions
With Polar, plans are charged in USD and renew automatically on the monthly or yearly cycle you chose. The amount and applicable tax are shown on the checkout page before you confirm. In the Mark Flow account menu, choose Manage billing to view invoices, update your payment method or cancel renewal. Cancelling renewal normally keeps your access until the end of the paid period; removing the extension does not cancel the subscription. Refund requests are assessed under the policy below.
Renewal
The current VietQR/bank-transfer flow is paid by you each time; nothing is debited from your bank account automatically. You can simply not buy the next period. An upgrade may be credited for the remaining time, as quoted by the system.
Duplicate or incorrect transactions
Have the order code, payment date, amount and transaction ID ready. Hide your balance, other transactions and any unnecessary information on the receipt. The operator needs to reconcile the payment before acting on it. Never provide your banking password or OTP.
When you can request a refund
You can request a refund within 7 days of the payment date if you paid twice for the same order; if you paid but the plan was not activated and support could not fix it; or if a core feature of the plan you bought does not work because of a Mark Flow fault that cannot be fixed within 3 business days of receiving a complete error report.
Refund amounts
Duplicate payment: the verified excess payment is refunded in full. Plan never activated: the full amount paid is refunded. Plan used but affected by an eligible fault: the fee for the remaining time is refunded, counted from the date of a valid request. Access for the refunded period ends when the refund is made.
What is not refundable
Changing your mind or no longer needing the plan after it has been activated and works normally; dissatisfaction with the quality of images or videos produced by an AI platform; running out of credits or quota, or an AI account being restricted or interrupted by a third-party platform. The cost of third-party accounts, credits or services is not part of a Mark Flow refund.
How to send a request
Email admin.markflow@gmail.com with the order code, account email, payment date, amount and reason. If you are reporting a fault, attach the error message or a screenshot with private information hidden. Do not send passwords or OTPs.
Response and processing time
Mark Flow replies within 2 business days. Approved refunds are processed within 7 business days, through the original payment method where possible; when the money arrives depends on the bank or payment provider.
