Privacy Policy

Effective: 1 September 2026　|　Last updated: 1 September 2026

This policy is drafted with reference to the Personal Information Protection Law of the People’s Republic of China, the Cybersecurity Law, the Data Security Law and related regulations.

1. Information we collect

1.1 Information you provide

When you submit an enquiry through the “Contact” or “Book a Demo” forms, we collect the details you enter: name, company/organization, phone number, email address, enquiry type and message. Name, company and phone are required; the rest are optional.

1.2 Information collected automatically

When you browse this site we may collect, via cookies and similar technologies: IP address, browser type and version, operating system, pages visited, access time and duration, and referring page. This information cannot by itself identify you.

1.3 Third-party analytics

This site may use analytics tools (such as Baidu Tongji or Google Analytics) to understand traffic, popular pages and referral sources, helping us improve content and experience.

2. How we use your information

We use your personal information only for the following purposes:

Responding to your enquiry, request or partnership interest and contacting you;
Providing product demos, solution briefings and technical support;
Sending product updates and industry insights where you have consented;
Improving the content, functionality and experience of this website;
Meeting obligations under law or responding to regulatory requests.

We will not use your personal information beyond these purposes. If the purpose changes, we will obtain your consent again.

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

You have given prior consent — for example, sharing your contact details with a regional partner;
Service providers — email and cloud providers that support site operation and notifications, bound to process data only for agreed purposes and to keep it confidential;
Required by law — where laws require it, or where judicial or administrative authorities request it through due process.

4. Storage and protection

Your personal information is stored on servers located within the People’s Republic of China. We protect it through transport encryption (HTTPS), access control and least-privilege management, among other technical and organizational measures.

We retain personal information only for as long as necessary: enquiry records are kept for 24 months from the last interaction, after which they are deleted or anonymized, except where law requires otherwise.

In the event of a personal information breach, we will activate our incident response plan as required by law and notify you and the relevant regulators.

5. Your rights

Under the Personal Information Protection Law you have the right to:

Access and copy the personal information we hold about you;
Correct and supplement inaccurate or incomplete information;
Delete your information where the purpose has been fulfilled, you withdraw consent, or we processed it unlawfully;
Withdraw consent at any time (withdrawal does not affect processing already carried out on the basis of consent);
Request an explanation of this policy and our processing rules.

To exercise these rights, contact us using the details below. We will respond within 15 working days.

6. Cookies and similar technologies

We use cookies to maintain core site functionality, remember your language preference and measure traffic. You can manage or delete cookies through your browser settings; rejecting essential cookies may prevent some features from working.

7. Minors

This site is aimed at enterprise customers and industry professionals and is not directed at children under 14. If you are a guardian and believe a child’s information has been collected, please contact us.

8. Policy updates

This policy may be updated as laws change or our business evolves. The updated version will be published on this page with a revised “Last updated” date; material changes will be highlighted prominently on the site.
