Privacy Policy

1. Who Is Responsible for Your Information

This website is operated by 广州灏晗信息技术有限公司 under the product brand SONDES, based in Nansha District, Guangzhou, Guangdong Province. If you have questions about information handling, you can contact us via Contact us through the channels listed on this page.

2. What Information We Collect

When you proactively submit project requirements, we will process the name or form of address, company or team, phone number or email address, industry, requirement type, and project description you provide. Contact information is used to respond to this inquiry. Please do not submit device keys, account passwords, unauthorized materials, or sensitive drawings through public inquiry forms.

To keep services running and prevent abuse, the server may process request times, access paths, browser types, and necessary network security logs. Consultation services do not rely on third-party advertising tracking scripts.

3. How Information Is Used and Stored

To follow up on inquiries, submitted details are sent through Feishu Mail to the operator’s designated QQ mailbox for authorized personnel only. To prevent repeated submissions, we store a salted hash of the IP address for daily limits; IPv6 addresses share a quota within each /64 subnet. Raw IP addresses are not stored in inquiry records.

Consultation information is used for requirements assessment, demonstration arrangements, technical communication, and necessary follow-up contact. We do not sell your consultation information or assume that your consultation consent applies to unrelated marketing. The information is stored in service environments deployed by the operator, accessible only to personnel with a work-related need, and cleared within the necessary period after processing is complete; where there is a statutory retention obligation, it is handled according to applicable requirements.

4. Browser-generated local requirements form

If online submission fails, you can download the project requirements form locally through your browser. The page will clearly indicate that it has not been submitted, and you are responsible for keeping the file. Downloading the file alone does not send the form to us.

5. External Provision and Service Boundaries

This website does not send your inquiry content to third-party AI models by default. Document uploads, device data processing, and AI features in the management platform are governed by the applicable terms of service and privacy notices. If new information processing purposes or third-party services are introduced in the future, we will update the relevant notices and seek consent where required.

6. Your Rights

You may request access to, correction of, or deletion of your inquiry information, withdraw consent to further contact, and raise questions about information processing. To protect information security, we may verify your connection to the relevant inquiry record. Withdrawing consent does not affect processing carried out with your consent before withdrawal.

7. External Links and Updates

This site may link to the regulatory filing platform, the management platform, and other websites. External websites process information according to their own policies. If this privacy policy changes materially, we will update the content and date on this page.
