Privacy Policy

This Privacy Policy applies to the official website operated by Zhuhai Changxian New Materials Technology Co., Ltd. ("Changxian", "we", "us", "our"). We process personal information in accordance with the applicable data protection laws of the jurisdictions in which we operate, including the Personal Information Protection Law of the People's Republic of China (PIPL) and, where applicable, the EU General Data Protection Regulation (GDPR).

This policy does not apply to third-party websites reached through links on this site. Please review the privacy policy of any third-party site before providing your information.

We follow the principle of data minimisation and collect only what is necessary:

• Enquiry forms — the name, company, phone number, email address, product of interest and requirement description you choose to submit.
• Server access logs — for security and availability we record request time, IP address, browser type and requested path.
• Cookies and local storage — used only for functional purposes such as remembering your language preference. We do not use advertising cookies or cross-site tracking.

We use the information we collect solely for the following purposes:

• Responding to your product enquiries, technical selection requests and sample requests;
• Communicating with you about orders, contracts and after-sales service;
• Protecting the security of this website and preventing malicious requests;
• Sending product updates and event invitations, but only where you have explicitly consented.

We do not sell your personal information. We will not share it with third parties except:

• Where we have your explicit consent;
• Where necessary to fulfil an enquiry or deliver a sample, to the limited extent required with our authorised distributors and logistics providers;
• Where required by law, or in response to a lawful request from a judicial or administrative authority.

Your personal information is stored on servers located within the territory of the People’s Republic of China. We retain it only for as long as necessary to fulfil the purposes described above, unless a longer retention period is required by law.

Once the retention period expires, we will delete or anonymise your personal information.

Subject to applicable law, you have the right to:

• Access and obtain a copy of your personal information;
• Correct or complete information that is inaccurate or incomplete;
• Delete your personal information, or withdraw consent you previously gave;
• Request an explanation of how we process your personal information.

To exercise any of these rights, please contact us using the details below. We will respond within 15 business days.

We protect your personal information with technical and organisational measures including transport-layer encryption (HTTPS), access controls and least-privilege principles, to prevent unauthorised access, disclosure, use, alteration, damage or loss.

In the unlikely event of a personal data breach, we will activate our incident response plan and notify you promptly via in-product notice or public announcement, as required by law.

This site uses only essential functional cookies and browser local storage, for example to remember your language preference. We do not use third-party advertising cookies and we do not track you across sites.

You can manage or clear cookies through your browser settings. Disabling essential cookies may prevent some features from working correctly.

We may revise this Privacy Policy from time to time. The updated version will be published on this page and the effective date above will be revised accordingly. If the changes are material, we will notify you by a prominent notice on the site.
