Privacy Policy

1. What information we collect

When you use the online inquiry form, we may collect:

• Information you provide voluntarily: name, phone number, company name, email, country/region, area of interest and message.
• Information collected automatically: IP address and submission time at submission, browser User-Agent, captcha interaction records; de-duplication and rate-limiting identifiers generated for anti-abuse purposes (no biometric information).
• Cookies and similar technologies: Third-party analytics/marketing scripts (such as Baidu Aifanfan and Google Analytics) may use cookies and similar technologies; see Section 8 for details.

Beyond the above, we do not collect sensitive personal information unrelated to your inquiry through this form, such as ID numbers, bank accounts or location trajectories.

2. Why we collect information and on what legal basis

• Responding to your inquiries, quotations and pre-sales/after-sales service requests, and following up with you;
• Routing inquiries to the corresponding industry/product line based on the area of interest, improving response accuracy;
• Anti-spam and anti-abuse: rate limiting, duplicate submission de-duplication, captcha and honeypot verification, and sensitive-word filtering;
• Legal compliance: retaining necessary communication records for audits, dispute resolution and regulatory requirements.

The legal bases are your consent (submission is deemed consent), what is necessary for entering into and performing a contract, and what is necessary for compliance with legal obligations.

3. How we use information

• Manually or systematically route inquiries to sales/customer service teams, who contact you by phone or email;
• Analyze the source and industry distribution of inquiries to improve products and services—no automated profiling or personalized recommendation;
• Trigger Webhook notifications configured on the website (such as inquiry creation events), pushing only desensitized necessary fields to the receiving addresses you have authorized.

4. How we store and retain information

• Storage location: servers within the People's Republic of China; if cross-border transfer is needed, we will obtain your separate consent and inform you of the overseas recipient's information.
• Retention period: inquiry messages are retained for no more than 3 years from submission, and deleted or anonymized upon expiry or withdrawal of your consent; where laws provide otherwise, such provisions prevail.
• Storage security: encrypted transmission (HTTPS), access control, operation log auditing and soft-delete isolation.

5. How we share and disclose information

We do not sell your personal information. We share it only in the following cases:

• With your separate consent;
• With entrusted processors (such as cloud service, SMS/email providers) under signed confidentiality and security agreements;
• As required by laws, administrative or judicial authorities, or as necessary to protect your or others' significant legitimate rights and interests.

6. Your rights

You have the rights to access, copy, correct, supplement, delete, withdraw consent, and restrict or refuse processing. You may exercise these rights via the contact information in Section 9, and we will respond within 15 business days; withdrawal of consent does not affect the lawfulness of processing carried out before the withdrawal.

7. Information security

We adopt physical, administrative and technical measures to safeguard information security, including least-privilege access, tiered approval, encryption in transit and at rest, captcha and rate limiting, and operation logging. Nevertheless, the Internet is not absolutely secure—please keep your contact information safe.

8. Cookies and similar technologies

The captcha on this website uses stateless verification and does not rely on cookies. If third-party analytics/marketing scripts are configured in the backend: on the Chinese site they are loaded directly, and you may refuse or clear the corresponding cookies via browser settings; on the English site we ask for your consent via a popup on first visit, and no such scripts are loaded before you consent—you can also change or withdraw consent anytime via “Cookie Settings” in the footer. These technologies are used only for this website's traffic statistics and marketing analysis.
