These cookies may be used for:

Core Website functionality;

Maintaining Website operation;
Saving essential Website settings.

These cookies are generally necessary for the Website to function properly.

Functional Cookies

Functional cookies may be used to remember language settings, user preferences, or other Website-related choices.

Analytics Cookies

If we use Website analytics or third-party analytics services, cookies or similar technologies may be used to measure Website traffic and usage.

Where applicable law requires consent for non-essential cookies, such cookies will be used only after the required consent has been obtained.

Other external websites.

When you leave our Website and use a third-party service, the processing of your information will be governed by that third party’s own privacy policy and terms.

DAQI Technology does not control the privacy practices of third-party websites or services, and we encourage you to review their privacy policies before providing personal information.

7. Sale of Personal Information

We do not sell personal information submitted through our product inquiry forms, sample requests, or contact forms.

We do not sell your contact information to third parties for unrelated independent marketing purposes.

Where applicable law provides specific rights relating to the sale or sharing of personal information, we will not discriminate against you for exercising those rights.

We may share limited information with trusted service providers where reasonably necessary to operate the Website or respond to your business request.

Such providers may include:

CDN and cybersecurity providers;
Email service providers;
Anti-spam and Website security providers;

Except where required by law or authorized by you, we do not disclose your personal information to unrelated third parties without a legitimate reason.

9. International Access and Cross-Border Data Processing

DAQI Technology operates in China and serves customers and Website visitors internationally.

Because Website infrastructure, CDN services, cybersecurity services, email systems, anti-spam services, or other technical services may use servers or network infrastructure located in different countries or regions, certain information may be processed outside the country or region where you are located.

Where cross-border personal data transfers are subject to applicable legal requirements, we will take reasonable measures required under the relevant law.

10. Data Retention

We retain personal information only for as long as reasonably necessary for the purposes described in this Privacy Policy.

As a general rule:

Ordinary product and technical inquiry information may be retained for up to 24 months after the relevant communication is completed;

Information required for contracts, accounting, taxation, legal disputes, or regulatory compliance may be retained for the period required by applicable law;
Website security logs may be retained for a reasonable period for cybersecurity, troubleshooting, and operational purposes;
Spam or malicious-submission records may be retained for as long as reasonably necessary to protect the Website.

When information is no longer reasonably required, we may delete, anonymize, or otherwise securely dispose of it.

11. Data Security

We take reasonable technical and organizational measures to protect personal information, including measures such as:

HTTPS-encrypted Website access;
Firewall and network security protection;
Website access controls;
Server and database security management;
Anti-spam and malicious-access protection;
Appropriate software and security updates.

However, no method of Internet transmission or electronic storage is completely secure, and we cannot guarantee absolute security.

To request restriction of processing in certain circumstances;
To object to certain processing activities;
To request data portability where applicable;

To lodge a complaint with an applicable data protection authority.

If you are located in California and applicable privacy law applies to DAQI Technology, you may also have rights relating to access, correction, deletion, and the sale or sharing of personal information.

Because DAQI Technology does not sell personal information collected through Website inquiries, we do not process such information for the purpose of selling it to third parties.

To exercise any applicable privacy rights, please contact us using the details provided below.

To protect your information from unauthorized access, alteration, or deletion, we may take reasonable steps to verify your identity before processing certain requests.

13. Marketing Communications

Submitting a product inquiry or contact form does not automatically subscribe you to marketing communications.

We may contact you regarding products, technical matters, projects, quotations, samples, or other business matters directly related to your inquiry.

We will not use a single inquiry as a basis for unrelated mass marketing without an appropriate legal basis or your consent where required.

If you have agreed to receive marketing communications, you may request to stop receiving them at any time.

This Website is primarily intended for business customers, engineers, technical professionals, procurement personnel, and other professional users.

It is not designed specifically for children.
