Product data source
Products, categories and available visual signals are retrieved server-side from a read-only catalog feed during scheduled static builds. Private access credentials are never sent to the browser.
Update labels
“Data updated” uses the product record’s own update timestamp. “Last sync” means the most recent successful site build. We do not change a product date merely to make a page appear fresh.
QC availability
A positive QC count means the source catalog reports that photos are available. It does not mean SheetLooks approved the item, seller or manufacturing quality.
Prices
Renminbi values come from the source catalog. Dollar values are approximate conversions and use a tilde. Product options, marketplace changes, service fees, domestic delivery and international shipping can change the final amount.
Indexing threshold
Only products with a title, category, image and available QC photographs receive indexable detail pages. Search and filter states are not added to the sitemap.
Editorial sources
Official sources support factual descriptions of platform workflows. Reddit is used to identify recurring questions and clearly labelled user experiences, not to establish universal facts.
