How we handle inquiry data, technical files, cookies, and advertising measurement

When you send an inquiry, request a quotation, upload a drawing, or contact us through WhatsApp or email, we may collect your name, company, email address, phone or messaging contact, country, product requirement, quantity, technical message, and uploaded files.

We may also collect basic website usage information such as page views, browser type, approximate location, device information, referral source, cookie consent status, and interactions with forms or advertising campaigns.

We use inquiry information to review technical requirements, prepare quotations, respond to sales questions, arrange samples, support orders, and improve our product pages and customer service process.

We use website analytics and advertising tags to understand whether our pages and Google Ads campaigns are working, including lead-form conversion measurement after a valid form submission.

Technical drawings, drill lists, specifications, and sample photos are used only for quotation review, manufacturability discussion, order communication, and related customer support.

If your project requires additional confidentiality, you may request an NDA before sending sensitive files. We do not sell customer drawings or technical files.

Our website may use cookies, Google Tag Manager, Google Ads tags, and analytics-related scripts to measure page visits, advertising performance, consent status, and lead conversions.

Where required, non-essential analytics or advertising storage is controlled through the cookie consent banner. You can accept or reject cookie use through the banner shown on the website.

We may share necessary information with internal sales, engineering, production, quality-control, logistics, and customer-service staff to process your inquiry or order.

We may use trusted service providers for website hosting, email delivery, analytics, advertising measurement, file handling, or logistics. These providers should use the information only for the services they provide to us.

We keep inquiry and quotation records for as long as needed to respond to your request, support repeat communication, maintain business records, comply with legal obligations, and improve our service process.

If you want us to delete or update your inquiry information, contact us using the details below. Some records may need to be retained where required for accounting, legal, dispute-resolution, or order-support purposes.

Our customers may be located in different countries. By contacting us or submitting a form, you understand that your information may be processed in China or in other locations where our website, email, analytics, or service providers operate.

We take reasonable steps to handle personal information securely according to the purpose for which it was provided.

You may choose not to submit a form or upload files. You may also contact us by email if you prefer to provide information directly.

Depending on your location, you may have rights to request access, correction, deletion, restriction, or objection regarding your personal information. We will review reasonable requests according to applicable law.
