After-Sales & Refund Policy

Effective Date: July 18, 2026

Publisher: Zhang Ming (individual developer, hereinafter "we" or "us")

This Policy is written and published in Chinese. This English text is a courtesy translation. In case of any discrepancy between this translation and the Chinese version, the Chinese version shall prevail.

1. Nature of the Product

  1. Licenses for the software offered on this website (e.g., SQLKit Pro) are electronic authorization information delivered online and constitute digital goods.
  2. Pursuant to Article 25 of the Law of the People's Republic of China on the Protection of Consumer Rights and Interests, digital goods delivered online are not subject to the seven-day no-reason return policy.
  3. The Free edition provides the core basic features. Please download and fully trial the Free edition before purchasing to confirm that the Software's features, performance, device compatibility, and your use case meet your expectations.
  4. Notice for EU Consumers: If you are a resident of the European Union / European Economic Area (EEA), you normally have a 14-day right of withdrawal for distance contracts under the EU Consumer Rights Directive (2011/83/EU). However, this license constitutes digital content not supplied on a tangible medium; once you explicitly request us to begin performance immediately and acknowledge that you will lose your right of withdrawal upon commencement of performance, your withdrawal right ceases. For specific provisions regarding the timing of delivery completion and the withdrawal right, please see Section 2.

2. Delivery and When Delivery Is Deemed Complete

  1. After you complete payment, you provide your Machine Info to customer service following the activation guide, and we issue a dedicated License File based on it.
  2. Once the License File is generated and sent through the communication channel of the platform where the order was placed (e.g., Taobao Wangwang / customer service chat) or another contact method you designate, delivery is deemed complete.
  3. If you request to cancel the order after payment but before the license is issued, we will issue a full refund.
  4. Exercise of the EU Withdrawal Right: Your act of providing Machine Info through the customer service channel and requesting us to issue the license immediately constitutes, within the meaning of Article 16(m) of the EU Consumer Rights Directive (2011/83/EU), "express consent to the beginning of performance" and "acknowledgment of the loss of the right of withdrawal". From the moment the License File is sent (i.e., delivery is complete), your right of withdrawal for this transaction ceases.

3. Refund Principles

  1. Because the license is an electronic information product custom-issued against the Machine Info of your device, it cannot be recalled or resold once delivered. Therefore, after delivery, refunds, returns, or revocations are not supported in principle, except in the exception cases described in Section 4.
  2. Before submitting your Machine Info, please confirm that it was correctly copied from within the app as instructed, to avoid an unusable license caused by incorrect information.

4. Handling of Verification Anomalies and Major Defects (Exceptions)

  1. A "verification anomaly" means: following the official activation guide correctly, the license still cannot be imported, activated, or verified, and upon investigation the cause is confirmed to be a license issuance error or a defect in the Software's licensing function.
  2. Process:
    • Step 1: contact customer service via the purchase channel or the contact methods published on this website, providing the order number, Machine Info, and screenshots of the error;
    • Step 2: cooperate with the necessary troubleshooting (e.g., confirming the software version and steps taken);
    • Step 3: if a verification anomaly is confirmed, we will first reissue or replace the license free of charge;
    • Step 4: if the issue remains unresolved through reissuance, replacement, or a software update within 7 business days from your first report, we will issue a full refund.
  3. The following are not verification anomalies:
    • the Machine Info you provided was wrong, incomplete, or not copied from within the app, causing a license mismatch (upon verification, we may reissue once free of charge);
    • after successful activation, the Machine Info changed because you switched devices, replaced core hardware, or reinstalled the system (handled under the device migration clause of the End User License Agreement; you may request a migration reissue, but it is not grounds for refund);
    • use of software obtained from unofficial channels or tampered/repackaged builds;
    • misunderstanding of the feature differences between the Free and Pro editions (differences are as published on the product page);
    • refusal to cooperate with necessary troubleshooting, making the issue impossible to diagnose;
    • refund requests for non-product reasons such as "no longer want it" or "bought by mistake".
  4. Major functional defects: if the license activates successfully but a major defect of the Software itself renders core Pro features (as published on the product page) unusable, and we confirm the issue but cannot resolve it through a software update or workaround within 7 business days from your first report, you may choose a full refund. Issues caused by factors other than the Software itself—such as your device environment, third-party software conflicts, or database server configurations—do not fall under this paragraph.

5. Device Replacement and License Reissuance

  1. If you need to migrate your license during the License Term due to a device change or system reinstallation, contact customer service with the details. Upon verification, we will reissue a license for the remaining term free of charge.
  2. For abnormally frequent reissuance requests, or suspected license sharing or resale, we may require additional verification and may restrict or refuse reissuance.

6. Third-Party Platform Transactions

  1. For orders placed on third-party e-commerce platforms (e.g., Taobao), payment and after-sales workflows follow the platform's rules; the substantive criteria for refund review are governed by this Policy, provided that where the platform's trading rules contain mandatory provisions to the contrary, those provisions prevail.
  2. Where the platform intervenes in a dispute, we will truthfully provide the platform with issuance and delivery records (such as the license delivery time and chat records) as the basis for handling.

7. Contact

For after-sales matters, please contact us first through the customer service channel of the platform where you placed the order, or via:
