Information we collect
Our inquiry forms collect your name, email address and message. Company, country and phone / WhatsApp are optional. We also receive information you choose to include about your equipment or project. Please do not submit identity documents, payment details or other sensitive personal information. Hosting and security providers may process technical request information, such as IP addresses and access logs, to operate and protect the website.
How we use information
We use inquiry information to respond to your request, clarify technical requirements, prepare quotations and follow up on the requested project. Submitting an inquiry does not subscribe you to a marketing newsletter. We do not sell inquiry information.
Storage and service providers
Inquiry details are stored in our website database and may be accessed by personnel handling your request. Website hosting, database and security providers process information as needed to provide their services. Our team operates in China; submitting a request from another country may involve processing your information outside your country.
Retention and security
We keep inquiry information for as long as reasonably needed to handle your request, related business correspondence and applicable recordkeeping obligations. The current system does not automatically delete inquiries after a fixed period. You can request deletion using the contact below. We use HTTPS and restricted administrative access to help protect information; no online system can guarantee absolute security.
Cookies and external links
The website may remember your language choice in browser storage. Hosting or security services may use essential cookies or similar technologies. Links to WhatsApp, Facebook or other external services are governed by those services’ privacy policies. This policy does not authorize advertising or other nonessential tracking.
Your choices and contact
You may contact [email protected] to request access, correction or deletion of your inquiry, or to object to further project follow-up. Include the email address used for the inquiry; we may need reasonable verification before acting. Some records may need to be retained for applicable legal or business obligations.
