Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCompliance Engine helps merchants identify and address compliance risks before they impact customers or orders. It monitors product pages, cart, and checkout, and displays warnings when defined rules are triggered. Merchants can create rule based conditions to control when messages appear, guide customer actions, and manage restricted or non compliant purchases.
If your store uses AI-generated descriptions, images, or chatbots, the EU AI Act requires you to disclose that to customers. Enforcement begins August 2026. This app scans your products, pages, policies, and apps to find content that needs transparency labels. It also checks for FTC issues like unsubstantiated health or green claims.
- Real-time compliance checks: Flag risks on product, cart, and checkout pages
- Rule-based control: Set conditions to trigger warnings or restrict actions.
- Checkout validation: Prevent orders that do not meet compliance requirements.
- One-click scan of products, pages, and policies for AI Act violations
- FTC checker flags unsubstantiated health, green, and product claims
