Merchant rows are filtered to public brand profiles with enough public data to link safely. Full workflow, filtering, and monitoring stay behind signup.
Review, pricing, feature, screenshot, and listing-change data come from public Shopify App Store and Shoplist crawl records. Signals can change between crawls.
