Privacy Policy

1. Scope

This policy applies to dqmade.cn and its subpages (both the Chinese and English sites). The site is operated by Dongguan Deqing Hardware Products Co., Ltd.

2. Information we collect

Information you submit: name, email, phone, company, country/region and message sent through the contact form. Name, email and message are required; the rest are optional.

Visit logs: to understand how the site is used and to keep it running reliably, we record the page path, visit time, referring domain, country/region code, and a truncated IP network (for example 203.0.113.0). We do not store the full IP address, do not store the browser User-Agent, and do not record clicks or scrolling.

What we do not collect: ID numbers, bank details, precise location, contacts, photos, or any other information unrelated to our business. We do not embed third-party advertising or behavioural tracking scripts.

3. How we use it

The information above is used only for the following purposes:

• Replying to your enquiry, quoting, sampling and discussing technical requirements
• Arranging production, delivery and after-sales contact
• Measuring site traffic so we can improve content and structure
• Detecting and blocking malicious requests to keep the site available

4. Cookies

This site uses no advertising or analytics cookies. Cookies are set in only two cases: (1) when you switch the interface language, we store dq_lang for 1 year to remember your choice; (2) when an administrator signs in, a dq_admin_session cookie keeps the session for 12 hours.

You can clear these cookies in your browser at any time. After clearing, the language falls back to automatic detection; normal browsing is unaffected.

5. Third-party services

We do not embed third-party analytics, advertising, chat widgets or social plugins. Third parties are involved in only two places:

• Maps: the contact page embeds an Amap (mainland China visitors) or Google Maps (overseas visitors) iframe. Your browser requests resources directly from that provider, which may receive your IP and device information under its own privacy policy.
• Email: enquiry notifications are delivered through Tencent Mail, so message content passes through that service in transit and storage.

6. Retention and location

Visit logs are kept for 180 days, consistent with the six-month network log retention requirement of China's Cybersecurity Law, and are deleted automatically afterwards.

Enquiry information is kept for 3 years from the last contact for order traceability and after-sales service, or deleted earlier at your request.

All data is stored on servers located in mainland China (Tencent Cloud) and is not transferred abroad. Should cross-border transfer ever be required, we will obtain your separate consent as required by law.

7. Your rights

You may request access to, correction of, or deletion of the personal information you submitted, and you may withdraw your consent (withdrawal does not affect processing carried out before it). Contact us using the details below; we respond within 15 working days.

8. Security

We protect your information with HTTPS encryption, administrator credential controls and least-privilege access. No transmission over the internet is absolutely secure, so please do not include ID numbers, bank details or other sensitive information in your enquiry.

9. Minors

This site is intended for business customers and is not directed at children under 14. If you are under 14, please use the site with a guardian or have your guardian contact us.

10. Changes

If this policy changes, we will update this page and its date. For material changes to purposes or categories of information, we will post a prominent notice on the home page.
