How MingCi ERP collects, uses, stores, and protects your information — including data accessed through the Amazon Selling Partner API (SP-API).

Effective Date: January 1, 2026  ·  Last Updated: January 1, 2026

1. Introduction

MingCi ERP ("MingCi", "we", "our", or "us") provides a software-as-a-service (SaaS) platform that helps Amazon sellers manage orders, inventory, analytics, and related operations through the Amazon Selling Partner API ("SP-API").

This Privacy Policy explains what information we collect when you use our website (tozoaioo.com) and our application (collectively, the "Service"), how we use and protect that information, and the choices you have. By using the Service, you agree to the practices described in this policy.

2. Information We Collect

2.1 Information You Provide

2.2 Information Collected Automatically

2.3 Information from Third Parties

3. Amazon Seller & SP-API Data

With your explicit authorization through Amazon's official Login with Amazon (LWA) flow, MingCi accesses your Amazon Seller Central data via the Selling Partner API in order to deliver the Service. We strictly comply with the Amazon Services API Developer Agreement, the Amazon Acceptable Use Policy, and the Amazon Data Protection Policy.

3.1 Categories of Amazon Data Accessed

Amazon PII Compliance: Customer PII is treated as confidential at all times. It is encrypted in transit and at rest, accessible only to authorized personnel on a strict need-to-know basis, used exclusively for the purposes you authorize, and never shared with third parties for marketing or any other unauthorized use.

3.2 Source of Authorization

All Amazon data is obtained through Amazon's official OAuth-based SP-API authorization flow. You may revoke MingCi's authorization at any time from within your Amazon Seller Central account (Apps & Services  >  Manage Your Apps), which immediately terminates our ability to access new data.

4. How We Use Your Information

We use the information described above only for legitimate, disclosed purposes:

We do not sell your personal information. We do not use Amazon customer PII for advertising, profiling, or any purpose other than fulfilling the specific function you have authorized.

5. Data Retention

We retain different categories of data for different periods, in accordance with applicable law and Amazon's policies:

5.1 Amazon Customer PII — 30 Days Maximum

Amazon Customer Personally Identifiable Information (PII) is retained for no longer than 30 days after order delivery, in strict compliance with the Amazon Data Protection Policy. After this period, customer PII is permanently and securely deleted from our active systems and backups, except where retention is required to comply with applicable tax, accounting, or legal obligations — in which case PII is moved to restricted, encrypted archival storage and is no longer accessible to operational systems.

5.2 Other Data

5.3 Deletion on Authorization Revocation

If you revoke MingCi's SP-API authorization or close your MingCi account, we will delete Amazon Customer PII within 30 days and other Amazon data within 90 days, except as required to comply with legal obligations.

6. Third-Party Sharing

We do not sell or rent your information. We share information only in the limited circumstances below:

6.1 Service Providers (Sub-processors)

We share information with trusted infrastructure and operational partners who help us deliver the Service:

All sub-processors are contractually bound to confidentiality and data-protection obligations equivalent to or stricter than those in this policy, and may use the data only to perform the services we have engaged them for.

6.2 Legal Requirements

We may disclose information if required to do so by law, subpoena, court order, or other valid legal process, or to protect the rights, property, or safety of MingCi, our users, or others.

6.3 Business Transfers

If MingCi is involved in a merger, acquisition, or sale of assets, your information may be transferred as part of that transaction. You will be notified by email and/or a prominent notice on our website of any such change.

6.4 No Marketing Use of Amazon PII

We never share, sell, or otherwise disclose Amazon customer PII to third parties for marketing or advertising purposes.

7. Data Security

We implement industry-standard technical and organizational safeguards designed to protect your information:

No method of transmission or storage is 100% secure. While we strive to protect your information, we cannot guarantee absolute security.

8. Your Rights and Choices

Depending on your jurisdiction, you may have the following rights regarding your personal information:

To exercise these rights, email us at mcyxtrade@outlook.com. We will respond within 30 days. We may need to verify your identity before processing your request.

9. International Data Transfers

MingCi operates internationally. Your information may be processed and stored in countries other than your country of residence, which may have data protection laws different from those in your country. Where required by law, we put in place appropriate safeguards (such as standard contractual clauses) to protect the transferred information.

10. Children's Privacy

The Service is intended for business use by adults. We do not knowingly collect personal information from children under 16. If you believe we have collected information from a child, please contact us so that we may delete it.

11. Changes to This Policy

We may update this Privacy Policy from time to time. When we make material changes, we will notify you by email and/or post a prominent notice on our website prior to the changes becoming effective. The "Last Updated" date at the top of this page indicates when the policy was most recently revised.
