Privacy Policy

Effective date: October 13, 2026.

Dongguan Sanmao Electronic Technology Co., Ltd. (public-facing brand: “SM”, “we”, “us” or “our”) respects the privacy of people who visit our website or contact us about a project. This Privacy Policy explains what information we collect through zynsil.com, why we use it, how it may be shared, and the choices available to you.

When you submit a request for quotation or contact us, we may collect your name, business email address, company, country or region, optional phone or WhatsApp number, project type, estimated quantity, target timing, project description, and communications relating to your inquiry. If you upload or email drawings, CAD files, photographs or other project materials, those files may also be processed for project review.

Please do not send personal information or confidential project information that is unnecessary for us to review your inquiry.

The website and inquiry form may collect limited technical and source information, including the page used to submit an inquiry, referring page, campaign parameters such as UTM source, medium, campaign, term and content, advertising click identifiers such as GCLID where available, and browser, device, IP address or basic request information used for security, delivery and troubleshooting.

If analytics or advertising measurement is enabled, we intend to configure it so that names, email addresses, phone numbers, free-text project descriptions, filenames and drawing content are not sent as analytics event parameters.

We may use information to:

• review and respond to inquiries;
• understand component, tooling, sample and production requirements;
• prepare or discuss quotations and next steps;
• communicate about drawings, samples, quality requirements and project progress;
• protect the website and form from spam, misuse or security threats;
• understand which pages or campaigns lead to relevant business inquiries; and
• maintain necessary business, technical or compliance records.

We may share information only as reasonably necessary with authorized SM personnel responsible for sales, engineering, quality, production or administration; service providers supporting hosting, email delivery, form processing, security, analytics or advertising measurement; and professional advisers or authorities where required by applicable law or necessary to protect legal rights.

We do not sell personal information submitted through the RFQ form.

SM is located in Dongguan, Guangdong, China. If you contact us from another country, your information may be transferred to and processed in China and in locations used by approved service providers, subject to applicable requirements.

We retain inquiry information and project files, including drawings submitted for review, only for as long as reasonably necessary to review and respond to the inquiry, manage an active or potential project, protect legal rights, and meet applicable legal, contractual or compliance obligations. Retention periods may vary according to the nature and status of the inquiry or project. Information that is no longer reasonably required may be deleted or anonymized.

We use reasonable organizational and technical measures intended to protect information from unauthorized access, loss, misuse or alteration. No website, email or storage system can guarantee absolute security. Avoid sending unnecessary confidential information through an unencrypted channel.

The website may use cookies or similar technologies for essential operation, security, preferences, analytics and advertising measurement. Where required, non-essential analytics or advertising technologies will be controlled according to the applicable consent choice.

Depending on your location and applicable law, you may have rights relating to access, correction, deletion, restriction, objection or withdrawal of consent. To make a request, contact us using the details below. We may need to verify the request before acting on it.

You may choose not to submit the RFQ form and may contact us through another published business channel.

Our website may link to third-party websites or communication services. Their privacy practices are governed by their own policies.

We may update this Privacy Policy when our website, services, measurement tools or legal obligations change. The current version will show its effective date.
