Privacy policy

1. Information we collect

When you submit an inquiry, we collect the information you choose to provide: your name, company, email address, country, product interest, target quantity and project details. If you contact us by email or through our Made-in-China store, we receive the information you include in that message.

Our hosting provider may automatically record standard technical information such as your IP address, browser type, referring page and the time of your visit. This information is used to operate and secure the website.

2. How we use your information

• To respond to your inquiry and prepare a quotation.
• To communicate about a sample, order or delivery.
• To improve our products, website and customer service.
• To comply with legal, accounting and tax obligations.

We do not sell your personal information. We do not use your information for unrelated marketing unless you ask us to.

3. Sharing

We may share information with service providers who help us operate the website, process email or deliver an order — for example, a hosting provider, email service or logistics partner. We only share what is necessary for the relevant service, and we require those providers to protect it.

We may disclose information if required by law or if necessary to protect our legal rights.

4. Cookies and analytics

This website does not set advertising cookies by default. A live-chat widget is available on every page so that you can talk to our sales team directly. When you open it, the widget may set functional cookies and store your conversation so that the chat continues if you move between pages.

If analytics or advertising tools are added later, this policy will be updated and, where required, a consent notice will be shown.

5. Retention

We keep inquiry and order records for as long as needed to respond to the request, fulfil the order and meet legal or accounting requirements. When information is no longer needed, we delete or anonymise it.

6. Your choices

You may ask us to access, correct or delete the personal information we hold about you, or to stop contacting you. Send your request to sales@chdtechgroup.com. We may need to verify your identity before acting on the request.

7. Security

We use reasonable technical and organisational measures to protect the information we hold. No method of transmission or storage is completely secure, so please avoid sending sensitive information that is not necessary for your inquiry.

8. Children

This website is intended for business users and is not directed at children. We do not knowingly collect personal information from children.

9. Changes

We may update this policy from time to time. The date at the top of the page shows when it was last revised.
