Payment Policy

Last updated: 01/11/2026

This payment policy sets out the methods and process of payment when users subscribe to paid learning plans on Haohin, an online Xiangqi (Chinese chess) learning platform.

Haohin provides information about payment methods so that users can review and choose a suitable method before making a transaction. Current e-commerce regulations focus on ensuring buyers receive full and transparent transaction information; the Law on E-Commerce 122/2025/QH15 and Decree 248/2026/NĐ-CP have been in effect since 01/07/2026.

1. Payment methods

Haohin currently supports the following payment methods. Each display language of the website offers only one method: customers using the Vietnamese interface pay by bank transfer via the PayOS gateway (VND); customers using any other language interface pay by PayPal (USD).

1.1. Bank transfer

The bank transfer method (scanning a VietQR code via the PayOS gateway, in Vietnamese dong) applies to users of the Vietnamese interface.

Haohin provides the bank account details or payment QR code on the payment page or during the user's transaction.

Users are responsible for carefully checking the details before transferring, including:

  • Name of the recipient person or entity.
  • Account number.
  • Receiving bank.
  • Amount to be paid.
  • Transfer reference, if required.

Users should only transfer funds using the official payment details displayed or provided by Haohin.

1.2. PayPal

Haohin offers the PayPal method (in US dollars, USD) to users of interfaces in languages other than Vietnamese.

When choosing PayPal, users may be redirected to PayPal's system to complete the transaction.

PayPal transactions are processed through PayPal's payment system and may be subject to PayPal's terms, policies and regulations.

Exchange rates, currency conversion fees or other charges applied by PayPal, banks or payment providers, if any, are handled in accordance with the rules of the respective provider.

2. Bank transfer payment process

The bank transfer payment process is generally carried out as follows:

  • 1. The user selects the learning plan they wish to subscribe to.
  • 2. Haohin displays information about the plan, its duration and the amount payable.
  • 3. The user selects the bank transfer method.
  • 4. The user makes the transfer using the details provided by Haohin.
  • 5. Haohin checks and confirms the payment.
  • 6. Once the payment is successfully confirmed, the corresponding learning plan is activated on the user's account.

Users must enter the correct transfer details if Haohin requests them, so that the system or support team can identify the transaction.

3. PayPal payment process

For international users who choose PayPal:

  • 1. The user selects a course package.
  • 2. Check the price, duration and details of the package.
  • 3. Select PayPal as the payment method.
  • 4. Complete the transaction through the PayPal system.
  • 5. PayPal processes the transaction and sends the payment result.
  • 6. After Haohin receives confirmation of successful payment, the corresponding course package is activated on the user's account.

If PayPal declines or does not complete the transaction, Haohin will not record the transaction as successfully paid until valid confirmation is received.

4. Payment confirmation and course package activation

A transaction is considered successfully paid when Haohin receives the payment or valid payment confirmation from the bank, PayPal or the relevant system.

After confirming successful payment, Haohin will activate the access corresponding to the course package the user registered for.

Users are responsible for checking the course package details after payment.

If payment was successful but the course package has not been activated, users can contact Haohin for checking and resolution.

5. Transaction information and value

Before making a payment, users need to check the transaction details, including:

  • Course package name.
  • Main content or access of the package.
  • Usage period.
  • Course package price.
  • Total amount to be paid.
  • Payment method.

The price applied to the transaction is the price displayed by Haohin to the user at the time of transaction confirmation.

Any taxes, fees or other costs related to the transaction, if applicable, will be shown or applied in accordance with legal regulations and the conditions of the corresponding payment method.

6. Failed transactions or incorrect payments

A transaction may not be recorded as successful in cases such as:

  • The user has not completed payment.
  • The transfer is incorrect or the amount is insufficient.
  • The transfer information is insufficient to identify the transaction.
  • The transaction is declined by the bank or PayPal.
  • The transaction is cancelled.
  • A technical error occurs during payment.

If the user transfers the wrong amount, wrong details, or has paid but the system has not recorded it, the user should contact Haohin and provide the necessary information to verify the transaction.

Haohin may request the transaction code, payment time, amount or payment proof for verification purposes.

7. Payment safety and security

Haohin does not ask users to provide bank account passwords, PINs, OTP codes, or similar security information via email, messages, or ordinary support channels.

For bank transfer transactions, users make payment through their bank or banking app.

For PayPal transactions, payment information is processed through PayPal's system in accordance with that provider's policies and security standards.

Users are responsible for safeguarding their bank account information, PayPal account, devices, and credentials.

Users should check the domain name, recipient details, and amount before making any transaction.

Haohin's processing of personal information related to transactions is carried out in accordance with Haohin's Privacy Policy.

8. Refunds

Refunds for completed payments are carried out in accordance with Haohin's Refund Policy.

Where a user is eligible for a refund, Haohin will issue the refund using a method appropriate to the original transaction or another method agreed by both parties and compliant with applicable law.

Any fees charged by banks, PayPal, payment organizations, or currency conversion arising during the refund process, if any, are handled in accordance with the Refund Policy and the regulations of the relevant payment service provider.
