Privacy & Data Policy

This sub-site publishes structured charcoal product and specification data. This page explains how that data is sourced and verified — and what this site does not collect about you.

Last updated: 2026-10-07

1. What this database publishes

Product records, size classes, packaging formats, applications and specification methodology. Every product record carries a verification status and a data source. No fabricated records are published: an empty field means the value is not established, and a record without a real source is not published at all.

2. Verification statuses

Supplier-declared — figures come from the supplier's own public listing; not independently tested by us.
Unverified — only basic identity confirmed.
Document-verified / third-party-tested — supporting documents or independent results exist.

Treat any value according to its stated status. Supplier-declared figures are claims to verify, not facts to rely on.

3. What we do not collect

This sub-site runs no analytics, no tracking cookies and no advertising pixels. We do not profile visitors. The hosting platform (Cloudflare Pages) may keep standard technical logs for security under its own policy.

4. Inquiries

Quote and sample requests are handled on the main site only — this sub-site has no forms. See the main site privacy policy and terms of use for the network-wide policy. Contact: sales@guotan.com.
