Privacy Policy

1. Who we are

This Privacy Policy explains how Zhengzhou Huamin Superhard Materials Co., Ltd., trading as Huamin Tools (“Huamin”, “we”, “us” or “our”), handles personal information in connection with hmcbn.com, product enquiries and our business communications.

We are responsible for the personal information that you provide to us for these purposes.

2. When this policy applies

This policy covers information collected through our website enquiry forms, quotation and application-support requests, email, telephone and WhatsApp communications. It also covers information you choose to submit to Huamin Tools through Facebook or Instagram lead advertisements, instant forms, messaging campaigns or other advertising enquiry forms that link to this policy.

It explains our use of information after we receive it. Meta, Google, WhatsApp and other independent platforms also process information under their own policies and settings.

3. Information we collect

Information you provide

• Contact and business details, such as your name, email address, telephone or WhatsApp number, company and country or region, where you provide them.
• Enquiry information, including product or application references, insert models, preferred grades, quantities, workpiece materials, machine details and machining requirements.
• Messages and correspondence, including drawings, photographs and other files you send to us by email or another agreed channel.
• Business, billing, delivery or transaction details where needed to prepare a quotation, manage an order or provide support.

Some form fields are optional. If you do not provide the contact details or information needed to understand your request, we may be unable to respond or prepare a suitable quotation. Please avoid sending unrelated sensitive personal information or payment-card details through an enquiry form.

Information collected through website use

Our website, hosting and analytics services may process IP addresses, browser and device information, pages visited, interaction times, referring pages, campaign parameters and cookie or similar identifiers. Enquiry forms may also record the referring product-page path to help identify the product you are asking about.

Information received from advertising platforms

If you submit a Facebook or Instagram instant form or another advertising enquiry form, we may receive the fields you choose to submit, answers to product questions and information identifying the relevant advertisement or form.

4. How we use information

• Respond to enquiries and communicate about your requested products, application review or quotation.
• Clarify specifications, quantities, drawings, supply details and order requirements.
• Provide customer support and maintain relevant business correspondence.
• Operate, secure and improve our website and forms, investigate technical issues and reduce spam or misuse.
• Understand website usage and the source of enquiries, including visits from advertising campaigns.
• Meet applicable legal, accounting and record-keeping obligations and handle disputes.

Where permitted by applicable law, we may send relevant product communications in accordance with your choices. Where consent is required for promotional communications, we will seek it separately. You can ask us to stop promotional contact at any time.

5. Facebook and Instagram advertising enquiries

When you voluntarily submit a Huamin Tools lead advertisement or instant form on Facebook or Instagram, the information is provided to us so that we can follow up on the request described in that form.

• We may contact you by the email address, telephone number or WhatsApp number you provide, taking account of your stated contact preferences.
• We use the information to discuss your enquiry, product selection, technical requirements and quotation, and for related purposes explained in this policy.
• Submitting an enquiry is not blanket consent to unrelated advertising or to every type of website tracking.
• We do not sell your enquiry contact details to data brokers or provide them to unrelated third parties for their own marketing.

You can request access, correction or deletion of information received by Huamin Tools from an advertisement, or ask us to stop contacting you, by emailing support@hmcbn.com. Please identify the email address or telephone number used in the form so we can locate the record.

Meta’s own handling of information, including interactions before a lead is shared with us, is described in the Meta Privacy Policy. You can also review advertising choices in your Meta account.

6. Cookies, analytics and advertising technologies

Our website uses WordPress and WooCommerce functions that can use cookies or similar technologies for site operation, sessions, security and enquiry or visit attribution. It also uses Google Analytics through Site Kit to help us understand visits and website interactions.

Depending on the technology and settings involved, these services may process device and browser details, page URLs, referral or campaign information, IP addresses and online identifiers. Learn more about how Google uses information from sites that use its services and the Google Analytics browser opt-out tool.

You can manage or delete cookies through your browser. Where a website cookie-preference control is provided, you can use it to change available choices. Blocking some cookies may affect website functions. Changing browser settings does not necessarily delete information already received by a service provider.

Where applicable law requires consent for non-essential analytics or advertising technologies, consent must be obtained before those technologies are used. Submitting an enquiry does not itself provide that consent.

If we introduce additional tools such as Meta Pixel, Meta Conversions API or customer-list advertising audiences, we will provide the relevant notices and obtain any permissions required before using those tools for that purpose. The advertising lead-form section above does not mean that these additional tools are currently enabled on the website.

7. Grounds for processing, where applicable

Depending on the information, purpose and applicable law, processing may be based on:

• Taking steps at your request before entering a contract, or performing a contract, such as preparing a quotation or managing an order.
• Legitimate business interests, where recognised by law, such as responding to business enquiries, maintaining a customer relationship and securing the website, after considering relevant individual interests.
• Your consent, where required, such as for certain promotional messages or non-essential tracking.
• Compliance with applicable legal obligations.

Where we rely on consent, you can withdraw it without affecting processing that was lawful before withdrawal.

8. Who may receive information

Information may be accessed by authorised Huamin Tools personnel who need it for the purposes above. Where necessary, we may also share relevant information with:

• Service providers supporting website hosting, security, maintenance, forms, email, business record management or analytics.
• Messaging and advertising platforms you choose to use, such as WhatsApp or Meta services.
• Professional advisers, logistics or transaction-support providers when needed for a business relationship or order.
• Authorities or other recipients where disclosure is required by law or necessary to establish, exercise or defend legal rights.

Information shared with a provider is limited to what is relevant to its role. Independent platforms may determine their own purposes for some processing, as described in their privacy policies.

9. How long we keep information

We keep enquiry and business-contact records for the time needed to handle the request, provide related support and maintain a relevant business relationship. We may keep certain order, accounting, dispute or compliance records longer where required or justified by applicable obligations.

The retention period depends on the nature of the enquiry, whether a business relationship develops, the need for follow-up or support, applicable record-keeping requirements and any ongoing dispute. Cookie and platform records may have separate retention periods controlled by the relevant service. You may contact us to ask about a particular record or request deletion, subject to applicable exceptions.

10. International processing

Huamin Tools is based in China. Information sent to us from another country may be received and processed in China. Our hosting, email, analytics, messaging or advertising providers may also process information in other countries.

Data-protection rules can differ between countries. Where applicable law requires safeguards, transfer conditions or specific consent, those requirements apply to the relevant transfer. Contact us if you need information about the arrangements applicable to your enquiry.

11. Your choices and privacy rights

Depending on applicable law, you may have rights to request access to your personal information, correct inaccurate information, request deletion, restrict or object to processing, receive a portable copy, or withdraw consent. You may also have rights relating to direct marketing or targeted advertising where applicable.

To make a request, email support@hmcbn.com with the subject “Privacy request”. Tell us which information and action your request concerns. We may need reasonable information to verify that the request relates to you. These rights can be subject to legal exceptions; we will respond within the time required by applicable law.

For promotional emails, use an unsubscribe option where provided or contact us directly. For telephone or WhatsApp promotional contact, tell us that you wish to stop. A marketing opt-out does not necessarily prevent a response to an enquiry you request or essential order communications.

You may also complain to the data-protection authority competent for your location where applicable. For information held independently by Meta, Google or WhatsApp, use the relevant platform’s privacy-request tools.

12. Security

We use reasonable organisational and technical measures appropriate to the information and purpose, including limiting access to people who need the information for their work. No internet transmission or storage system can be guaranteed completely secure. Please contact us if you suspect that information you sent to Huamin Tools has been misused.

13. Children

Our industrial products, website and business enquiry services are intended for business users rather than children. If you believe a child has provided personal information to us, contact us so we can review and address the situation.

14. External platforms and links

Links to third-party websites and platforms are provided for convenience. Their privacy practices are controlled by the relevant provider. This policy does not replace their policies. You can review the Meta Privacy Policy, WhatsApp Privacy Policy and Google Privacy Policy.

15. Updates and contact

We may update this policy to reflect changes in our services, data practices or applicable requirements. The date at the top identifies the latest version. Where required, we will provide additional notice or seek the necessary consent for a material change.
