Part II: Refund Policy

Article 3: General Principles

3.1 Tokens Plan subscriptions, add-on packages, and similar products sold by the platform are virtual goods or digital services delivered online and are deemed delivered when activated. Under Article 25 of the Law of the People's Republic of China on the Protection of Consumer Rights and Interests, these products are not subject to the seven-day right to return goods without giving a reason. As a general rule, purchases are not eligible for no-questions-asked refunds.

3.2 Exception: If a platform-related issue, such as an extended service outage that cannot be resolved within a reasonable period, prevents the user from using the service normally, the user is entitled to a prorated refund for the affected portion. No refund processing fee will be charged in this situation.

Article 4: Tokens Plan Subscription Refunds

4.1 A user requesting a refund for personal reasons must provide the relevant supporting documentation. If the platform determines after review that a refund is warranted and the request was not caused by the platform, the refund will be calculated as follows:

Refund amount = Amount paid × Refund percentage − Refund processing fee Refund processing fee = Amount paid × 13%

4.2 The refund percentage is the lower of the following two values:

• (A) Remaining days in the validity period ÷ Total days in the validity period
• (B) Remaining allowance ÷ Total allowance

If the plan has more than one billing cycle (one month) remaining, percentage (B) is adjusted as follows:

(Number of complete billing cycles remaining + Remaining allowance in the current cycle ÷ Allowance for the current cycle) ÷ Total number of billing cycles

4.3 No refund will be issued if the amount calculated under the formula above is less than or equal to zero.

Article 5: Add-On Package Refunds

5.1 An add-on package is a one-time purchase of virtual allowance and, as a general rule, is not eligible for a no-questions-asked refund.

5.2 If a user requires a refund for personal reasons and the request was not caused by the platform, the refund will be calculated as follows:

Refund amount = Amount paid × (Remaining allowance ÷ Total allowance) − Amount paid × 13%

The portion corresponding to used allowance is nonrefundable. No refund will be issued if the calculated amount is less than or equal to zero.

Article 6: Nonrefundable Circumstances

1. An account is banned or a subscription is canceled for violating Part I of this policy;
2. Free or complimentary allowances, promotional discounts, and amounts covered by coupons;
3. The service cannot be used because of the user's own network, device, account-management practices, or similar circumstances;
4. Any other circumstance specified by law or regulation.

Article 7: Refund Process

7.1 Users must submit refund requests and the relevant supporting documentation through the official WeCom customer-support channel.

7.2 The platform will complete its review within five business days after receiving a complete application and will communicate the result through an in-app notice, WeCom, or email.

7.3 Once approved, the refund will be returned through the original payment method and is expected to arrive within 10 business days, subject to the payment provider's processing time.
