1. Introduction and scope
Zhengzhou Suishida Trading Co., Ltd. ("we", "us", "our") provides ERP software services to cross-border e-commerce sellers. Through https://www.juzhongerp.com and the Juzhong ERP software product (together, the "Service"), we give you tools to manage products, orders, inventory, purchasing, logistics and finance for your stores across multiple marketplaces (Amazon and Ozon are supported as of the date of this policy).
This policy explains how we handle personal information and business data in the course of providing the Service: what we collect, why we use it, who we share it with, where it is stored, how long we keep it, and how you can exercise your rights.
This policy applies to the Service, including this website and the Juzhong ERP software clients. It does not apply to the privacy practices of third-party marketplaces such as Amazon or Ozon. Their handling of your personal information is governed by their own privacy policies.

3.2 Information provided through marketplace APIs once you authorize

- Financial data: settlement statements and fee breakdowns such as commission, storage, advertising and logistics fees.
About order recipient information: recipient names, addresses and phone numbers in order data are buyer personal information. For this information, you are the data controller and we act as your processor. We process it only on your instructions and only to the extent necessary to fulfil and ship orders. We do not use it for any other purpose.

- We never ask for or store your Amazon or Ozon account login credentials;
- We do not collect buyer payment card or bank account details;
- We do not collect sensitive personal information unrelated to providing the Service.
4. How we use information

- Account and identity management: account creation, sign-in verification, permission assignment and account security;
- Fulfilment and reconciliation: calculating marketplace fees and profit, and generating operating reports;
- Customer support: responding to your enquiries, diagnosing issues and handling complaints;
- Service security: detecting anomalous sign-ins, preventing fraud and abuse, and maintaining stability;
- Legal compliance: retaining records and cooperating with investigations as required by law or regulation.
- We do not use your store data or marketplace data for advertising, marketing or profiling;
- We do not sell, rent or otherwise make your data available to any third party for its own purposes;

5. Legal bases for processing
We process your personal information in accordance with the Personal Information Protection Law of the People's Republic of China and other applicable laws, on the following bases:
- Performance of a contract: processing account information, marketplace credentials and business data to provide the Service to you;
- Your consent: by registering an account, authorizing a store or contacting us, you consent to our processing as described here. Where separate consent is required — for example for international transfers — we will obtain it separately;
- Legal obligation: processing required to comply with laws and regulatory requirements;
- Legitimate interests: processing log and device data to keep the Service secure and stable, without exceeding what is necessary.
You may withdraw your consent at any time. Withdrawal does not affect the lawfulness of processing carried out before withdrawal, but it may mean you can no longer use the corresponding features of the Service.
6. How we share information
We do not sell your personal information. We share information only in the limited circumstances below.
6.1 Writing data back to the marketplaces you authorized
To fulfil orders, we transmit shipping information — such as carrier name and tracking number — back to Amazon or Ozon through their official APIs. This is an intrinsic part of the Service, and the data transmitted is limited to what that operation requires.
6.2 Service providers acting on our behalf (sub-processors)
We may engage third parties such as cloud infrastructure providers to help deliver the Service. These sub-processors may process data only on our instructions and only to provide the Service. We enter into data processing agreements with them covering confidentiality, security measures and deletion requirements, so that they are bound to protection standards no lower than those in this policy.
| Sub-processor type | Purpose | Data involved |
|---|---|---|
| Cloud infrastructure providers | Servers, databases, storage and networking | All data stored in the Service |
| SMS / email notification providers | Sign-in verification, security alerts and service notices | Your phone number or email address |
| Logistics providers | Shipment creation, label printing and tracking | Order recipient name, address and phone number |
We will keep this list current on this page and notify you of material changes.
6.3 Legal requirements
Where we are compelled by law, judicial or administrative authority to disclose information, we will do so only to the extent required, and will inform you where legally permitted to do so.
6.4 Other circumstances with your consent
Other than the above, we will not share your data with any third party without your explicit consent.
7. International transfers
To provide the Service, we may need to process data within the People’s Republic of China and in other jurisdictions. Where personal information is transferred internationally, we will:
- Obtain your separate consent in advance, informing you of the recipient's identity and contact details, the purposes and methods of processing, and the categories of information involved;
- Complete the applicable compliance procedures, such as a security assessment, personal information protection certification, or standard contractual clauses;
- Require the overseas recipient to provide a level of protection no lower than that required domestically and no lower than this policy.
If you do not consent to international transfers, please do not enable features that require them, or contact us to discuss an alternative.
8. Storage location and retention
Service data is stored by default on servers located within the People’s Republic of China.
We retain information only for as long as necessary to achieve the purpose of processing:
| Category | Retention period |
|---|---|
| Account information | Deleted or anonymized within 30 days of account closure |
| Marketplace credentials | Deleted within 30 days of unbinding or authorization revocation |
| Store business data (products, orders, inventory, finance) |
Retained while the Service is active; deleted within 30 days after termination or upon your deletion request |
| Order recipient personal information | Retained for as long as necessary to fulfil and support the order, then deleted or anonymized |
| Access logs and API call records | Retained for 6 months for security auditing and troubleshooting |
Where laws or regulations mandate a specific retention period — for example for financial and tax records — we retain the relevant data for the statutory period and use it only to satisfy that legal requirement. Once the retention period expires, we delete or irreversibly anonymize the data.
9. Security measures
We apply technical and organizational measures consistent with industry practice to protect your data:
- Encryption at rest: marketplace API keys and authorization tokens are encrypted with AES-256; they are never stored or displayed in plaintext;
- Encryption in transit: all client-server communication is protected with TLS against interception and tampering;
- Password protection: account passwords are stored as bcrypt one-way hashes; we cannot recover your plaintext password;
- Access control: least-privilege principles govern menu, action and data permissions; staff can access only the data they need for their role;
- Data isolation: each seller account is an isolated data space; business records are validated against ownership and cross-account queries are not performed;
- Audit trails: sign-ins, order handling and configuration changes are written to audit logs for investigation;
- Personnel controls: staff with data access sign confidentiality agreements and receive regular data-security and compliance training;
- Incident response: we maintain a data security incident response plan and assess system security regularly.
Despite these measures, no internet environment is absolutely secure. Please keep your account password safe and notify us immediately of anything unusual.
10. Specific commitments on marketplace data
As a solution provider to marketplaces including Amazon, we accept the following additional commitments when processing data obtained through official marketplace APIs. Where these conflict with other parts of this policy, this section prevails:
- Purpose limitation: marketplace data is used solely to provide the features of the Service described to you — never for advertising, marketing, resale, competitive analysis or building a separate data product.
- No external sharing: we do not share marketplace data with any third party except as necessary to fulfil orders or where legally compelled — in particular buyer personal information in order data.
- Data minimization: we request and provide only the API permissions required for the features you actually use, and do not over-request scopes.
- Security: we apply encryption, access control and auditing to marketplace data, and ensure that personnel with access are bound by confidentiality obligations.
- Retention and deletion: marketplace data is retained only as long as the Service requires. Where your authorization is revoked, your account is closed, the Service ends, or the marketplace requests deletion, we will delete or return the relevant data within 30 days and confirm this to you.
- Cooperation with the marketplace: we cooperate with reasonable audits by marketplaces regarding their data protection requirements, and adjust our processing promptly when marketplace policies change.
- Incident notification: where a security incident affects marketplace data, we will notify you promptly as required by law and cooperate with the marketplace's investigation and remediation where necessary.
11. Your rights
To the extent permitted by applicable law, you have the following rights over your personal information:
- To be informed and to decide: to know how we process your personal information, and to restrict or object to that processing;
- Access and copy: to access the personal information we hold about you and obtain a copy;
- Rectification: to have inaccurate or incomplete information corrected or completed;
- Erasure: to have your personal information deleted in the circumstances provided by law, including where you withdraw consent, the Service ends, or we process unlawfully;
- Withdraw consent: to withdraw consent you have previously given at any time;
- Data portability: to receive your data in a structured, commonly used, machine-readable format, or to have it transferred to a provider you designate;
- Explanation: to request an explanation of our personal information processing rules;

Where a buyer requests deletion of personal information contained in your store data, we act as your processor and will assist with deletion on your instructions. If a buyer contacts us directly, we will refer the request to you.
12. Cookies and similar technologies
This website (https://www.juzhongerp.com) uses only strictly necessary cookies and local storage, to maintain your sign-in session, remember your language preference and keep sessions secure.
We do not use third-party advertising cookies for cross-site tracking, and we do not use cookies to collect information for profiling. You can clear or disable cookies in your browser settings, though some features may then not work correctly.
13. Minors
The Service is intended for business users and cross-border e-commerce operators, not for minors. We do not knowingly collect personal information from minors. If we learn that we have collected a minor's personal information without verifiable guardian consent, we will delete it promptly.
14. Notification of security incidents
In the event of a personal information breach, tampering or loss, we will immediately activate our incident response plan and take remedial measures. As required by law, we will promptly notify you of the nature of the incident, its likely impact, the measures taken, the steps you can take to protect yourself, and how to reach us, and we will report to the relevant authorities.
15. Changes to this policy
We may revise this policy in response to business changes, legal developments or marketplace policy updates. Revised versions are published on this page with an updated "Last updated" date at the top.
For material changes — such as new categories of data collected, expanded purposes of use, changes in sharing recipients or international transfer arrangements — we will give you advance notice through prominent means such as in-product notifications or email, and will seek your consent again where required. If you do not agree with the changes, you may stop using the Service and close your account.
