Windows edition opening for purchase soon
| Original channel | Application window |
|---|---|
| WeChat Pay | Within 365 days after payment |
| Alipay | Within 12 calendar months after the transaction |
Each window starts at the verified payment time and excludes its upper endpoint. Alipay uses Asia/Shanghai calendar months with month-end clamping; it is not a fixed 365-day window. These voluntary windows do not limit statutory rights.
The server confirms the eligible amount, original channels and exact deadlines. Confirm only after reviewing the quote. Request submission does not mean refund success.
Version 2026-11-14. These rules cover voluntary refunds for first-launch Windows WeChat Pay and Alipay orders in mainland China. Purchasing is opening soon; real refund applications are not yet open. support@mentorbriefai.com is for questions, privacy and legally necessary matters; it does not promise manual payment reconciliation or code issuance.
WeChat Pay. Apply within 365 days after successful payment. The start is the verified payment time of the original order, not ordering, downloading, activation or a renewal click. Trusted server time applies: [successful payment time, successful payment time + 365 days), excluding the upper bound. Date-only comparisons cannot extend it. A calendar-year entitlement can have 366 days: you may still have entitlement late in the term after this application window ends. Annual payment is not a promise of voluntary refund at every point in the year. Statutory obligations remain.
Alipay. Apply within 12 calendar months after the transaction: from the verified original payment time until the same local time 12 calendar months later in Asia/Shanghai, excluding that endpoint. If the original day does not exist in the final month, use that month’s last day. This is not a fixed 365-day window and does not use the WeChat deadline formula.
Use Asia/Shanghai. Total days are the local date difference between term start and end. The application day is used; remaining dates run from the next day through the day before the term-end date, clamped to zero through total days. Refund in fen = actual fen paid for that term × remaining days / total days, rounded down to an integer and capped at actual payment. Example only: ¥19 paid, 31 total days and 10 remaining days gives floor(1900 × 10 / 31) = 612 fen, or ¥6.12. This is no real order. Window eligibility is separate: a positive amount does not reopen an expired window. Upgrade payments must be allocated to their original orders without duplicate refunds.
Formal service must freeze the original order, term, amount and application identity on acceptance. Retries query that same application. Merchant acceptance, provider acceptance, processing, final success and funds arrival are distinct facts. Near-window failure or an accepted request cannot be presented as a guaranteed completed original-route refund. Real handling, provider execution and arrival instructions are not open and require qualification. Do not send credentials or order materials by email now.
Processing does not revoke entitlement. Only final provider success updates its corresponding term and issues a higher-revision revocation. A late old-term refund must not cancel a verified new term. Refunds do not release slots, erase the unique trial or reset safety watermarks. Offline devices may retain an old signed lease until its original deadline, bounded by that lease and original entitlement; instant offline revocation is not promised. Existing history, reports, configuration and safe completion of transactions with existing effects remain, without duplicate delivery.
Both monthly and annual purchases are actively confirmed once, without automatic debit or renewal. No advance collection for the next term before the current paid term expires. Confirm at expiry or later; late payment starts a new term from its confirmation. Calendar months and years are not fixed 30/365 days. At launch, WeChat Pay and Alipay follow their distinct original-payment refund windows above. Real purchases remain closed until release qualification.
Mandatory rights and operator obligations under applicable law remain; this commercial voluntary window does not mean all later claims are rejected. Raise disputes through the published contact and seek competent remedies under applicable law. New versions will state version, effective date and material changes without retroactively reducing established order rights. The real self-service refund route will be identified when purchasing opens.
