Privacy notice
How Shandong Langchuan Technology Co., Ltd. handles the information you send through this site. Last updated 2026-11-13.
Who we are
This site is operated by Shandong Langchuan Technology Co., Ltd., Licha Town Industrial Park, Jiaozhou, Qingdao, Shandong, China. For any question about this notice or your data, write to xuecici86@gmail.com.
What we collect
Only what you type into the quote form or send us directly: your name, company, email, country, the product you are asking about, target quantity, target market and your requirement text. We also receive the date and time of the request so we can answer in order.
We do not run advertising or analytics trackers on this site, and we do not set cookies for tracking. Our hosting provider keeps standard server logs (IP address, requested page, timestamp) for security and uptime, as every web server does.
Why we collect it
To answer your enquiry: prepare a quote, propose materials or a sample, and follow up on that specific request. We do not use it for unrelated marketing, and we do not sell, rent or trade it.
Who else sees it
Our sales desk, and the technical providers that make the site and the form work: the hosting provider, and the form-handling service that delivers the message to our mailbox. Those providers process the data on our instructions and are not permitted to use it for their own purposes.
We will disclose information if a court or a competent authority requires it.
How long we keep it
Enquiry records are kept for up to 24 months so that a repeat order or a claim can be traced, then deleted. If you ask us to delete your enquiry sooner, we will.
Your rights
You can ask us for a copy of what we hold about you, ask us to correct it, or ask us to delete it. Write to xuecici86@gmail.com and we will respond within 30 days. If you are in the EU or UK, you also have the right to complain to your local data protection authority.
Links to other sites
This site links to WhatsApp and, when we publish them, to our own social accounts. Once you leave this site, the privacy policy of that platform applies. We do not control what they collect.
Changes
If this notice changes, the date at the top of this page changes with it. Material changes will be noted on this page rather than announced elsewhere.
