Terms & conditions checkbox + age verification popup + I agree checkbox at checkout - 1 min setup
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

The country and product-specific settings are a nice feature. It makes it much easier to manage different requirements depending on what customers are purchasing.

Really easy to set up and works exactly as expected. The terms checkbox and age verification features are simple to manage and saved me from having to make any custom code changes.
