This policy explains what personal information Henan Tianyuan Environmental Protection Technology Co., Ltd. collects through this website, why we collect it, and what we do with it.
Contact for any question about this policy or about your data: tianyuanep@163.com.
Who we are
This website is operated by Henan Tianyuan Environmental Protection Technology Co., Ltd., No. 699 Pingyuan Road, Xinxiang City, Henan Province, China. We manufacture oil processing, rendering and environmental protection equipment and supply complete lines to customers worldwide.
The website address is https://tianyuanep.com.
What information we collect
Information you send us
When you submit an enquiry through the Contact page or the Get a Quote page, we collect the information you enter in the form:
- Your name
- Your email address
- Your WhatsApp number or telephone number, if you provide one
- Your country
- The raw material and capacity you are working with
- Your message
The enquiry is delivered to our company mailbox so that our engineers can prepare a reply and a quotation.
Information collected automatically
Like most websites, our servers record standard technical information when you visit — for example your IP address, browser type and the pages you request. This information is used to operate the site, diagnose faults and protect against abuse. It is not used to identify you personally.
We also use Google Analytics 4 to understand, in aggregate, how the site is used — which pages are visited, how visitors arrive, and which countries they come from. Those reports are statistical; we do not use them to identify individual visitors. See the Cookies and analytics section below.
How we use your information
We use the information you provide only to:
- Answer your enquiry and prepare a technical proposal or quotation
- Provide technical service, spare parts and after-sales support
- Keep a record of the business relationship
We do not sell your information, and we do not send you unrelated marketing messages. We do not use your enquiry details for any purpose other than dealing with your enquiry or the resulting order.
Who we share your data with
We do not sell or rent personal information. Information is disclosed only where it is necessary:
- Shipping and forwarding agents — to arrange delivery of equipment you have ordered
- Banks and customs brokers — to process payment and export documentation
- Service providers — where a third party operates part of our website or email infrastructure on our behalf
- Analytics provider — Google, for the Google Analytics measurement described in Cookies and analytics above
- Authorities — where we are legally required to disclose information
How long we keep your data
Enquiry records and correspondence are kept for as long as necessary to serve the business relationship and to meet our legal, accounting and export record-keeping obligations. Technical server logs are kept for a short period and then overwritten. If you ask us to delete your enquiry details and we are not required by law to keep them, we will do so. Aggregated analytics data is retained inside Google Analytics according to the data-retention setting of our analytics property, and is then deleted automatically.
Cookies and analytics
A cookie may be set where it is technically necessary for the site to work.
We also use Google Analytics 4 (measurement ID G-ML29KEYZFN) to measure how the site is used. Google Analytics sets first-party cookies in your browser — principally _ga and _ga_ML29KEYZFN — which distinguish one browser from another so that visits can be counted and attributed. The results reach us only as aggregated statistics; they do not identify you by name.
The reporting we can see includes pages viewed, number of visits and sessions, approximate location at country or city level, device and browser type, and the source that brought you to the site. We have not enabled Google Signals or any advertising, remarketing or data-sharing features.
For this purpose Google acts as our service provider and processes the data on our instructions under Google’s Data Processing Terms. Google may also process the data as described in Google’s own privacy policy: https://policies.google.com/privacy
You can refuse or delete these cookies through your browser settings, and you can prevent Google Analytics from collecting your data by installing the Google Analytics opt-out browser add-on: https://tools.google.com/dlpage/gaoptout . Blocking analytics cookies does not affect your ability to use the site or to send us an enquiry.
If we introduce further analytics or advertising tools, this policy will be updated before those tools are used, and any consent required by the law applicable to you will be collected at that time.
Embedded content from other websites
Pages on this site may include embedded content — for example a map or a video hosted elsewhere. Embedded content from another website behaves in the same way as if you had visited that website directly: it may collect data about you, use cookies, and track your interaction with the embedded content. We do not control that data collection. Please refer to the privacy policy of the site concerned.
How we protect your data
This site is served over HTTPS, so information submitted through the enquiry forms is encrypted in transit. Access to the company mailbox that receives enquiries is restricted to the staff who deal with them.
Your rights
Depending on where you live, you may have the right to:
- Ask what personal information we hold about you, and receive a copy
- Ask us to correct information that is inaccurate
- Ask us to delete information we no longer need
- Object to, or ask us to restrict, certain processing
- Withdraw consent where processing is based on consent
To exercise any of these rights, email tianyuanep@163.com and tell us what you would like us to do. We will respond within a reasonable period.
Changes to this policy
We may update this policy to reflect changes in how we operate the website or in the law. The current version is always the one published on this page. Last updated: 22 September 2026.
