2. Information We Collect

This is a static informational website. It has no registration, login or online payment functionality, and it does not actively collect personal information from visitors. We receive information only in these cases:

• When you contact us — if you reach out by email or telephone, we receive the information you choose to provide, such as your name, company, contact details and the content of your enquiry.
• Server access logs — to keep the site running and secure, our hosting provider may record access logs including IP address, timestamp, requested page and browser type.

3. How We Use Information

We use the information described above only to:

• respond to your enquiries and handle cooperation matters;
• maintain the website, diagnose faults and prevent security risks;
• meet obligations imposed on us by applicable law.

We do not use your information for automated decision-making, and we do not send marketing communications unrelated to these purposes.

4. Cookies and Local Storage

This website does not use advertising or profiling cookies and does not embed third-party analytics. If we introduce such features in future, we will update this policy and notify visitors on the website.

5. Storage and Protection

We apply reasonable technical and organisational measures to protect your information, including HTTPS encryption across the whole site, restricting server access to personnel who need it, and minimising retention of information received by email.

This website is hosted on cloud infrastructure located outside mainland China. If you are located elsewhere, please note that your information may be transferred to and processed on servers outside your country or region.

6. Sharing and Disclosure

We do not sell, rent or trade your personal information. We share it only:

• with service providers — hosting and email providers that support the operation of this website, to the limited extent necessary, under confidentiality obligations;
• where required by law — in response to a lawful request from a judicial or administrative authority.

7. Retention

We retain information only for as long as necessary for the purposes described in this policy. Enquiry correspondence is generally retained for no longer than 24 months after the business relationship ends. Server access logs are retained for our hosting provider's default period. After that, information is deleted or anonymised.

8. Your Rights

You have the right to:

• access the information we hold about you;
• request correction of inaccurate information;
• request deletion of your information;
• withdraw any consent you previously gave (without affecting processing already carried out);
• object to, or lodge a complaint about, our processing.

How to exercise these rights: email shiweikeji88@163.com stating your request and enough information for us to verify your identity. We will respond and act within 15 business days.

9. Third-Party Links

Our product section contains links to Amazon product pages. This website does not sell products directly and does not receive any transaction or payment information. Once you follow a link to Amazon, your information is handled under Amazon's own privacy policy, which we do not control and are not responsible for.

10. Children

This website is intended for businesses and commercial partners, not for children. We do not knowingly collect personal information from children. If you believe we have done so, please contact us and we will delete it.

11. Changes to This Policy

We may update this policy to reflect changes in our business or applicable law. The revised version will be published on this page with a new "last updated" date. For material changes we will post a prominent notice on the home page.
