Privacy Policy

1. Information we collect

We collect only what is necessary to provide our services.

• Information you provide: name, email, company, country or region, enquiry topic and message submitted through the contact form.
• Information collected automatically: pages visited, visit time, browser and device type, and a hashed form of your IP address.
• We do not collect identity document numbers, payment card numbers, biometric data or other sensitive personal information on this website.

2. How we use it

• To respond to your enquiry, provide quotations, send samples and perform our contracts.
• To understand website traffic and improve our products, services and content.
• With your consent, to send business-related product updates or industry news. You can ask us to stop at any time.

3. Sharing and processors

We do not sell your personal information. To operate this website we engage the following providers to process limited data, and require them to act on our instructions:

• Hosting and content delivery: Vercel Inc. (global network)
• Database hosting: Alibaba Cloud RDS (Shenzhen, China); the site itself runs on Vercel Inc. (overseas regions)
• Email delivery: if enabled, Resend Inc., used only to send business email
• We may disclose information where required by law or where necessary to protect our legitimate rights and those of our users.

4. Retention

Enquiry records are kept while we remain in contact with you. After the business relationship ends we retain them for a reasonable period to meet legal obligations (contract, tax and export-compliance requirements), then delete or anonymise them.

5. Cookies and analytics

This website uses first-party analytics that we operate ourselves, in order to understand page views, approximate traffic sources and how pages are read, so that we can improve the content.

That measurement uses two cookies set by this site: a randomly generated visitor identifier (to count unique visitors, kept for 1 year) and a session identifier (to tell whether requests belong to one visit, kept for 1 day). They are used only on this site and contain no name, email address or account information.

We do not record your IP address, and keep only the coarse location (country / region / city) supplied by our CDN. We do not run third-party advertising here, we do not use cross-site advertising trackers, and we do not embed any third-party analytics platform.

You may reject or clear cookies in your browser. Doing so does not limit what you can read on the site; you will simply be counted as a new visit.

6. Your rights

You can contact us at any time using the details below to:

• ask what information we hold about you and request a copy;
• have inaccurate information corrected;
• request deletion of your information or restriction of processing;
• opt out of marketing messages.

7. International transfers

Our servers and database may be located outside mainland China. Where information is transferred across borders we require our providers to apply appropriate safeguards such as encrypted transmission.

8. Security

We protect data with HTTPS encryption in transit, least-privilege access and salted password hashing. Please note that no transmission over the internet can be guaranteed to be completely secure.

9. Children

This website serves business and institutional customers. It is not directed at children, and we do not knowingly collect personal information from them.

10. Changes to this policy

We may update this policy from time to time; the date at the top of this page will change accordingly. We will highlight material changes on the website.
