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.

NOT SATISFIED VERY BAD APP
CheckMate was incredibly easy to set up and works exactly as expected. The terms & conditions checkbox and age verification features help keep our store compliant without affecting the customer experience. Everything is configurable, and no coding was required. Highly recommended!
I liked Checkmate because it did not overcomplicate things. We sell products where we wanted an age confirmation step, but we did not want to make customers upload documents or go through a long verification process. The checkbox gate is clean and easy to use. It adds a professional touch to the store and gives us a simple way to ask customers to confirm they meet the age requirement.
