Refund Policy

Last updated: September 7, 2026

This Refund Policy explains when and how you can request a refund for purchases of points (also called “credits”) made on https://yzdesignai.com. It is part of, and should be read together with, our Terms of Service. The operator is the individual publishing under the brand name “YZ AI / 元筑AI” (“we”, “our” or “us”).

Points are digital credits used to pay for AI features as you use them. They are delivered to your account immediately after a successful purchase (or after you redeem an activation code) and are consumed in small amounts each time an AI feature runs. There is no subscription: we do not charge recurring fees, and nothing is charged automatically after a purchase.

1. Scope: What a Purchase Covers

This policy covers two ways of paying for points: (a) redeeming an activation code that we issue through channels we make available, and (b) any future online card payment processed on the Service by a third-party payment provider (such as Creem). Both give you the same thing — a points balance on your account — but the refund handling differs as set out below.

2. When We Grant a Refund

  • You bought an activation code but have not redeemed it. Because an unredeemed code has no value to you yet, you may return it and request a refund within 14 days of purchase, as long as the code has not been redeemed or partially used. We will cancel the code so it can no longer be used.
  • You paid but the points were not added to your account (for example, a payment succeeded but the credit failed to arrive, or you were charged twice by mistake). We will correct this — by crediting the missing points or, if you prefer, refunding the duplicate or failed charge.
  • A feature you were charged for failed because of an error on our side and the points were deducted without producing the result you paid for. We will refund the points used for that failed task, or the corresponding payment if the failure was on a paid task you cannot retry.
  • Where mandatory law gives you a right to a refund in a particular situation, we will honour it (see Section 4).

3. When Refunds Are Not Available

  • Points have already been consumed by AI usage, or the design outputs (analyses, drafts, plans, renderings, reports) you paid for have already been generated and delivered to you. Used points cannot be reversed because the underlying AI service has already been provided to you.
  • An activation code has already been redeemed. Once redeemed, points are added to your account and are treated the same as points obtained by any other method.
  • The request is made more than 14 days after purchase and does not fall under Section 2 or a statutory right.
  • We reasonably believe the purchase involved fraud, an unauthorised resale, abuse of a refund or chargeback, or a violation of our Terms of Service.

If we agree to refund points for an unused balance in a situation where you cannot keep using the Service, the refund is calculated on the unused points only and follows the pricing under which you obtained them.

4. Your Statutory Rights

Nothing in this policy limits rights you have under mandatory law — including, for users in mainland China, consumer-protection law. Where such law requires a refund, repair or other remedy that differs from this policy, the law prevails.

5. How to Request a Refund

To request a refund, email us at 719542959@qq.com and include: the account email or Google account you use, the purchase or order information (for example the activation code or the Creem order/receipt number, if you have one), the date and amount, and a short explanation.

We aim to respond within five (5) business days. If we approve a refund, we will process it to the original payment method where feasible, typically within fifteen (15) days after approval and subject to the payment provider’s own processing time. If we decline a refund, we will explain why. If you believe our decision is wrong, please reply to the same email and we will review it.

6. Online Card Payments and Third-Party Providers

When online card payment is enabled on the Service, it is processed by a third-party payment provider (such as Creem). That provider acts as the merchant of record or payment processor for card transactions and applies its own terms, refund and dispute rules. We will honour this Refund Policy for purchases made through it, and you may also be able to raise a dispute directly with the provider. If you request a refund through us after the provider’s own window has closed, we will still review it under this policy.

The Service is an independent, unofficial product: it is not affiliated with, sponsored by or endorsed by any AI-model company or official body.
