Website privacy
Privacy Policy
This website is operated by Zibo Xin Longdi Environmental Protection Technology Co., Ltd. (淄博新隆迪环保科技有限公司, “Xin Longdi”). This notice explains how we handle information you choose to send through the website, especially Contact and Request for Quote inquiries.
Last updated: 2 October 2026
Information we receive
The inquiry form asks for your name, work email, company, country or region, inquiry type and message. You may also provide a WhatsApp number, product or equipment, material, quantity, dimensions or specifications, and application details. The form may carry the page you came from, selected inquiry context, site language and submission time.
Our hosting and email services may also process ordinary technical information needed to receive, secure and deliver a request, such as an IP address, browser information and service logs.
How we use it
We use the information to respond to your inquiry, review drawings and technical requirements, prepare quotations, and communicate about the products or projects you asked us to discuss. We also use necessary technical information to operate and protect the form. This website does not currently run advertising or analytics tracking.
Drawings and files
File uploads through the website inquiry form are temporarily unavailable. The server rejects inquiries that include an attachment. Please describe your requirements in the form and contact us first to arrange how to share drawings if needed.
Please do not put passwords, unrelated sensitive personal information or confidential drawing content into the form message. We do not currently provide a dedicated malware-scanned file-sharing service through this website.
Where information goes
Your browser submits the form to our Vercel-hosted server endpoint. The server passes the inquiry text to Resend for email delivery to our inquiry mailbox. Our application does not write the inquiry to its own database, object storage or public file directory. Vercel, Resend and the mailbox provider may process or retain information as part of their services.
Retention and access
Inquiry emails and relevant service records may remain with the recipient mailbox and service providers. Earlier inquiries that included attachments may also remain in those records. Access to our inquiry mailbox is limited to company-authorized personnel and is not shared publicly. We keep inquiry emails and historical attachments only as long as needed to handle inquiries, quotations, project discussions and reasonable business records, and delete or clear them when no longer needed. A fixed retention period has not yet been set; provider records may follow their own retention practices. Contact us if you want to request review or deletion of information you sent.
Security and international processing
We validate form submissions and reject file attachments. No internet transmission or email can be guaranteed completely secure. Because the website, email delivery and mailbox are supplied by third-party services, information may be processed in countries other than yours. Do not submit material requiring a special confidentiality arrangement before agreeing one with us directly.
Your requests
You can ask what information you submitted, request a correction or deletion, or raise a privacy concern by emailing the address below. We will assess and respond to the request in light of the information we hold and any applicable obligations.
Changes
We may update this notice if our contact process, service providers or website data practices change. The current version is available on this page. If analytics are enabled later, we will update this notice before describing them as active.
