Privacy Policy

Information We Collect

When you send an inquiry, we may collect your name, company, email, country, message, current page, original landing path and campaign parameters included in the link you used.

How We Use Information

We use submitted information to answer product questions, prepare quotations, discuss orders and understand which page or campaign led to the inquiry.

Session Attribution

During the current browser session, the website may use session storage to retain the original landing path and the standard campaign fields utm_source, utm_medium, utm_campaign, utm_term and utm_content when they are present in a link. This keeps the source attached when you move between pages and then open the configurator or send an inquiry. The session record is not used to enable Google Analytics when analytics consent is denied and is normally cleared when the browser tab or session ends.

Cookies and Google Analytics

We use Google Analytics to understand visits, page views, traffic sources, interactions and inquiry-related actions. Google Analytics may use cookies or similar technologies when you grant analytics consent. If you reject analytics cookies, analytics storage remains disabled. We do not use Google Analytics to send personally identifiable information to Google or for advertising personalization.

Service Providers

The website uses service providers including Vercel for hosting, FormSubmit for inquiry delivery and Google Analytics for website measurement. Information is shared only as needed to operate these services or comply with law. Learn more about how Google uses information from sites that use its services.

Retention and Security

We retain business inquiry information for as long as reasonably needed for communication, legal obligations and commercial records. Analytics retention is managed through Google Analytics settings. No internet transmission can be guaranteed completely secure.

You can accept or reject analytics cookies using the privacy notice shown on the website. To ask about your information, contact paul@shandongtongcai.com. You may also choose to contact us directly by email or WhatsApp.
