This Privacy Policy explains how Nanjing Hengmu Machinery Co., Ltd (“HENGMU”, “we”, “us”) collects, uses, and protects your personal data when you visit https://hengmu-machine.com or contact us through the site.
1. Who we are
We are a manufacturer of biomass and feed pellet machinery based in Nanjing, Jiangsu, China. For any privacy question or request, contact us at darren@hengmu-machine.com.
2. What data we collect
- Inquiry form data. When you submit the “Get a Quote” or contact form, we collect the name, phone number, email address, and message content you provide. We use this information only to answer your inquiry, prepare quotations, and follow up on your equipment requirements.
- Shop-related data. If you create an account or place an order in our online store, we collect the information needed to process the order (contact details, shipping address, order history). We do not store full credit-card numbers on this site.
- Technical data. Like most websites, our hosting provider logs your IP address, browser type, and pages visited for security and performance purposes.
3. Cookies
We use a small number of cookies that are required for the site to work: session cookies for the shopping cart, login cookies for registered users, and comment-related cookies if you leave a comment. Analytics or marketing cookies, if any, will only be set with your consent. You can disable cookies in your browser at any time; some shop functions may stop working.
4. Third-party services
Data may be processed by the following categories of providers, each under its own privacy policy:
- Our hosting and CDN provider, which stores site data in secure data centers;
- Email services, used to receive and reply to your inquiries;
- Embedded content (for example, videos or maps) — when you interact with embedded content, the provider may collect data as if you visited its own website.
We do not sell or rent your personal data to anyone.
5. How long we keep your data
Inquiry records are kept for up to 24 months so we can follow up on your project. Shop order records are kept as long as required for accounting and warranty purposes. You may request earlier deletion at any time.
6. Your rights
You may request at any time: a copy of the personal data we hold about you, correction of inaccurate data, or deletion of your data. To exercise these rights, email darren@hengmu-machine.com. We will respond within 30 days.
7. Data security
The site is served over HTTPS, and access to inquiry records is restricted to authorized sales staff. No method of transmission over the Internet is 100% secure, but we take reasonable technical and organizational measures to protect your data.
8. Changes to this policy
If we change this policy, the updated version will be posted on this page with a new “last updated” date.
