Refund Policy

Updated: October 26, 2026 · Effective: October 26, 2026 · Version: v2.0

This Refund Policy applies to all paid purchases in PerfectRefs (今日宜引文) (the "service"). This Policy forms an integral part of the Terms of Service with equal legal effect; where this Policy and the Terms of Service are inconsistent, this Policy prevails. Please read this Policy carefully before purchasing, in particular the provisions displayed in bold.

This Policy applies to purchases made on Gumroad and to other purchases made through the English-language version of the service. Purchases paid in Chinese yuan (RMB) through the Chinese-language version are governed by the Chinese 《退款政策》 instead.

1. Paid Products

The service offers two types of paid products:

  1. Packs: one-time purchases; credits are issued immediately upon purchase;
  2. Passes: prepaid fixed periods of use (the period stated on the purchase page); credits are issued in full for the entire period. Passes carry no auto-renewal and no automatic charging; when a Pass period ends, no further charge is made and the Pass does not renew — to continue using the service, you make a new purchase.

2. Credit Validity

Purchased credits (whether issued from a Pack or a Pass) are to be used within the validity period or Pass period stated on the purchase page. Upon expiry, unused credits lapse automatically and are not refunded, converted to cash, or compensated. Credits obtained free of charge are not subject to this Policy.

3. Refund Rules

Packs and Passes are network-delivered virtual products provided on a payment-first basis; the fees are the price of the corresponding online services, and are not of the nature of prepayments, deposits, earnest money, or stored value.

  1. This product is a digital service supplied immediately after purchase; once supply has begun, purchases are not eligible for a no-reason return or a statutory right of withdrawal, to the extent the law applicable to you permits. Under Article 25 of the PRC Consumer Rights Protection Law and Article 19 of its Implementing Regulation, this requires that we mark it conspicuously and that you confirm it at the time of purchase; where the law of your country of residence gives consumers a right of withdrawal for online purchases (as in the European Union), it requires your prior express consent to immediate supply and your acknowledgement that you thereby lose that right. At Gumroad checkout you give both by ticking a required checkbox before paying. Without that confirmation we will not decline a refund on this ground;
  2. Once purchased, a Pack is non-transferable and non-refundable (except in cases of breach on our part, such as a material defect of the service rendering it entirely unusable, where this Policy provides otherwise, or where a refund is required by law);
  3. A Pass may be refunded in full within seven days of purchase, provided that no check has been run on the account since the purchase; for a Pass bought on Gumroad, this means no check since you redeemed its license key, and a key not yet redeemed also qualifies; once a check has been run since then, or more than seven days after purchase, the Pass is non-transferable and non-refundable (subject to the same exceptions as the preceding item);
  4. Results reflect the coverage and current state of public academic databases; disagreement with a result does not fall within the exceptions above;
  5. Where the service is suspended or terminated because of your breach of the Terms of Service, fees paid are not refunded.

4. Duplicate Charges and Non-Delivery

  1. In the event of a duplicate or erroneous charge, the overcharged amount will be refunded upon verification;
  2. Where, for reasons attributable to us (including service failure or prolonged unavailability), a purchased service cannot be delivered, the amount corresponding to the undelivered portion will be refunded upon verification.
  3. Where, for reasons such as business adjustments or force majeure, we change, suspend, or terminate part or all of the service and this results in a purchased Pack or Pass not being fulfilled, we will refund the amount corresponding to the unused portion, except as otherwise provided by law.

5. Refund Process

  1. Send a refund request to support@perfectrefs.com with the payment order number, the email address of the account, and the reason for the refund. If you bought on Gumroad, you can instead reply to your Gumroad receipt email; give the Order ID shown on the receipt, the email address you used on Gumroad, the reason, and, if you have redeemed the license key, the email address of your account. Please do not send us the license key itself;
  2. We will verify the records and respond with a decision within five business days of receiving the request;
  3. Refunds are returned via the original payment channel (for a Gumroad purchase, through Gumroad to the original payment method, in the currency you were charged); the time of arrival depends on the processing times of the payment service provider and the relevant payment institutions; if a purchase is refunded (including a refund the payment provider grants under its own rules) or charged back, we may withdraw the unused credits issued for it, and a Pass period it added ends.

6. Miscellaneous

  1. Nothing in this Policy excludes or limits any rights you enjoy under law, including the mandatory consumer rights of your country of residence, or any refund that Gumroad, as the merchant of record, grants under its own terms;
  2. If this Policy is revised, we will announce the revision on the site and update the version and effective date; the revised Policy applies from the announced effective date;
  3. Disputes arising from refunds are governed by the governing-law and dispute-resolution provisions of the Terms of Service.
