Privacy Policy

Last updated: August 18, 2026

This Privacy Policy explains how Nantong HengMing Machinery Co., Ltd. (“HengMing”, “we”, “us”, or “our”) handles information collected through https://hmsigmamixer.com/, including our product, service, and inquiry pages.

Who We Are

We operate this website to introduce sigma mixers, kneaders, and related engineering services and to respond to business inquiries from customers and partners worldwide.

Information You Provide

When you submit an inquiry, we may collect your name, business email address, country, material or application details, requested volume, voltage, frequency, phase, discharge method, heating or cooling requirements, vacuum or inverter requirements, message, and any files that you choose to upload. Please do not upload information that you are not authorized to share.

We use this information to understand your requirements, prepare technical or commercial responses, arrange follow-up communication, and provide related customer service.

Information Collected Automatically

When you browse or submit an inquiry, the website may record your IP address, first landing page, submission page, traffic source and medium, and campaign identifiers such as UTM parameters or GCLID when available. This helps us respond to inquiries, understand how visitors reach the site, prevent abuse, and maintain website security.

Approximate IP Location

For inquiry records, we may use the visitor IP address to obtain an approximate location and network description from an IP geolocation service. The resulting fields may include country, region, city, postal code, internet service provider, network organization, and autonomous system number (ASN).

IP-based location is approximate and may be incorrect, especially when a visitor uses a VPN, proxy, corporate gateway, mobile network, or shared connection. It is not used to determine an exact street or home address. The IP address and related lookup data may be stored with the inquiry record for business follow-up, security, and audit purposes.

How We Use Information

We may use collected information to answer inquiries, prepare quotations or technical recommendations, communicate about requested equipment or services, improve website content and usability, detect spam or abuse, protect the website, keep business records, and meet applicable legal or regulatory obligations.

Email and Third-Party Services

Inquiry records are stored in the WordPress website database and inquiry emails are delivered through our configured email service. Information may also be processed by service providers used for IP geolocation, website hosting, email delivery, analytics, security, or file handling. We do not sell or rent inquiry information to third parties.

Cookies and Analytics

WordPress and the website may use necessary cookies or similar technologies for administration, security, session handling, and basic website functionality. Where enabled, analytics or session-analysis tools such as Google services or Microsoft Clarity may collect technical and usage information, subject to their own privacy policies and settings.

Retention, Security, and International Transfers

We keep inquiry information for as long as reasonably necessary to respond to the inquiry, manage a business relationship, maintain security and accounting records, resolve disputes, or meet legal obligations. We use reasonable technical and organizational measures to protect the information, but no internet transmission or storage system can be guaranteed to be completely secure.

Because we work with customers and service providers in different countries, information may be processed or stored outside your country. We take reasonable steps to use appropriate service providers and protect information during these transfers.

Your Choices and Requests

You may contact us to ask about the personal information associated with your inquiry, request correction of inaccurate information, or request deletion where we are not required to keep it. We may need to verify the request and may retain limited information where necessary for security, legal, or legitimate business purposes.
