Privacy Policy

Last updated: 9 August 2026

1. Who is responsible for your information

Hainan Sinyoung Rubber Machinery Co., Ltd. operates hnsinyoung.com and is responsible for the personal information described in this notice. Our address is No. 6 Hengwu Road, Yunlong Industrial Park, Yunlong Town, Qiongshan District, Haikou City, Hainan Province, China. Privacy questions and requests may be sent to [email protected].

2. Information we collect

When you submit a project inquiry, we collect the information you enter, such as your name, business email, company, country or region, project type, capacity, feedstock or rubber grade, preferred contact details, and project requirements. We may also receive the page from which you submitted the form and advertising campaign parameters such as UTM values or a Google click identifier.

Our hosting and security providers may process technical data needed to deliver and protect the website, including IP address, request time, browser or device information, requested URL, and security events. The inquiry endpoint uses a one-way hash of the visitor IP address for short-term rate limiting and does not place the raw IP address in the inquiry email.

If you consent to analytics or advertising measurement, Google Analytics and Google Ads may process information about visits, interactions, devices, and advertising attribution. Optional analytics and advertising storage is denied until you make a choice in the privacy controls.

3. Why we use information

• To receive, assess, and respond to your requested quotation or technical inquiry.
• To communicate about equipment configuration, engineering, delivery, and after-sales support.
• To operate, secure, diagnose, and improve the website.
• With your choice, to understand website performance and measure Google Ads inquiry results.
• To comply with applicable legal, accounting, or dispute-resolution requirements.

Depending on the applicable law and context, these activities may be based on steps you ask us to take before a contract, performance of a contract, our legitimate interests in responding to business inquiries and protecting the website, legal obligations, or your consent for optional analytics and advertising technologies.

4. Cookies and consent choices

The website stores a necessary privacy-choice record so it can remember your selection. Google Analytics and Google Ads measurement are controlled through Consent Mode v2. You can accept, reject, or customize optional analytics and advertising choices and reopen “Privacy choices” at any time. Withdrawing consent does not affect processing that occurred before withdrawal.

5. Who may receive information

Inquiry information is delivered to Sinyoung personnel who handle sales, engineering, project delivery, or customer support. We may use service providers for website hosting, security, email delivery, analytics, and advertising measurement, including Google where you permit the relevant optional processing. Providers may process information only for their service functions and under their own applicable terms and safeguards.

6. International processing

Sinyoung is based in China and serves international customers. Your inquiry may therefore be transferred to and processed in China or in other countries where relevant service providers operate. Data protection rules may differ by country. Where required, we use appropriate contractual, technical, or organizational safeguards.

7. How long we keep information

Project inquiries are normally retained for up to 24 months after the last substantive contact, unless a longer period is needed for an active customer relationship, contract, legal obligation, or dispute. Short-term anti-spam rate-limit records expire after approximately 15 minutes. Analytics and advertising information follows the retention controls configured in the relevant Google services.

8. Your choices and rights

Depending on your location, you may have rights to request access, correction, deletion, restriction, portability, or objection, and to withdraw consent. You may also have the right to complain to your local data protection authority. To make a request, email [email protected]. We may need to verify your identity before completing a request.

9. Security and required information

We use reasonable technical and organizational safeguards, including encrypted transport, server-side validation, restricted mail credentials, and anti-spam controls. No internet transmission is completely risk-free. Fields marked as required are needed so we can understand and respond to the inquiry; you may instead contact us directly by email.

10. Changes to this notice

We may update this notice when our website, services, or legal obligations change. The current version and update date will remain available on this page.
