Privacy Policy

This policy explains how Hongshuntong Valved Mufflers Factory ("HST", "we", "us") handles information collected through hstexhausttech.com.

Information we collect

When you submit a business inquiry, we may collect your name, company, email address, country or region, business type, estimated purchase quantity, project requirements, and the page used to submit the inquiry.

How we use information

We use this information to respond to inquiries, prepare quotations, confirm product compatibility, communicate about orders, prevent abuse, and improve our website and services. We do not sell personal information.

Analytics and advertising cookies

With your consent, we use Meta Pixel to measure visits and advertising performance. Meta may receive browser and device information and page activity under its own privacy terms. You may decline optional analytics cookies in the consent banner.

Legal basis and international transfers

Where required by law, we rely on consent for optional analytics and on steps requested before entering a contract, contractual necessity, or legitimate business interests for responding to B2B inquiries. Information may be processed in China and by service providers in other countries, subject to appropriate safeguards where required.

Retention and security

We retain inquiry information only for as long as reasonably needed for sales follow-up, order records, legal obligations, dispute prevention, and security. We use reasonable technical and organizational safeguards, but no internet transmission is completely secure.

Your choices and rights

Depending on your location, you may request access, correction, deletion, restriction, or objection, and may withdraw consent for future analytics. Clearing this website's local storage will reset the cookie choice.
