Information We Collect
When you contact us or request a quotation, we may collect your name, company, business email, country or region, telephone or WhatsApp details, product interests, technical requirements, dimensions, quantities, messages and files you choose to upload. We may also receive basic technical records such as IP address, browser type, requested pages, timestamps and security logs from our hosting and website systems.
How We Use Information
- Respond to product, technical, partnership and quotation inquiries.
- Review drawings, recommend materials and assess manufacturability.
- Prepare quotations, samples, orders, delivery and after-sales support.
- Maintain website security, prevent abuse and diagnose technical problems.
- Meet accounting, export, compliance and other legal obligations.
Depending on the situation, processing is based on your request, steps toward a contract, performance of a contract, our legitimate business and security interests, legal obligations, or consent where required.
Drawings and Uploaded Files
Files submitted through the quotation form are used only to evaluate and respond to your request. The website temporarily handles the upload to deliver it to the responsible team. Copies may remain in business email or project records for quotation, order and repeat-order support. Do not submit information you are not authorized to share.
Sharing and International Transfers
We do not sell personal information. Information may be shared with authorized employees, hosting and email providers, logistics or professional service providers, and public authorities when legally required. Because LH Stone operates from China and serves international customers, information may be processed outside your country. We use reasonable contractual, organizational and technical safeguards appropriate to the service.
Retention
General inquiries and unsuccessful quotation records are normally reviewed for deletion or anonymization within 24 months. Order, accounting, warranty, compliance and approved technical records may be retained longer where required for contractual, legal or repeat-order purposes.
Security
We use access controls, encrypted website connections, controlled account access and operational procedures designed to protect submitted information. No internet transmission or storage method can be guaranteed completely secure.
Your Choices and Rights
Subject to applicable law, you may request access, correction, deletion, restriction, objection, portability or withdrawal of consent. You may also complain to your local data-protection authority. We may need to verify your identity before acting on a request.
Cookies and Language Directories
The website uses separate public URLs for each available language. Choosing a language navigates to that language directory and does not load a third-party translation service. Essential WordPress, hosting and security functions may still process technical information required to deliver and protect the website. See our Cookie Policy for details.
Children
This business-to-business website is not intended for children, and we do not knowingly seek personal information from children.
Policy Updates
We may update this policy when our website, services or legal obligations change. The effective date above identifies the current version.
