CheckMate feature overview with key capabilities

Add terms & conditions checkboxes and age verification to your store in 1 click. No code needed.

CheckMate helps merchants stay legally compliant by adding consent checkboxes and age verification to their store. It protects three key points: the cart page (theme block), the cart drawer (app embed), and checkout (Plus only, with tamper-proof server-side validation). Each component is enabled separately in the theme editor. No code required. Also supports product-specific rules, country-based age thresholds, multiple custom checkboxes, and timestamped acceptance logging for compliance.

1-click enable for terms & conditions checkbox on your cart page
Age verification popup with configurable thresholds and session memory
Blocks express checkout buttons until terms are accepted
Product and collection rules for targeted compliance requirements
Analytics dashboard with acceptance rates and CSV/JSON export

Fantastic solution for age-restricted products. The country-based age thresholds are a huge advantage for international stores. Highly satisfied.
