GateKeeper — Age Verification

GateKeeper adds a reliable age gate so only age-appropriate visitors can browse and buy. The storefront gate is a lightweight (~2KB) theme app extension that won't slow your store or hurt your Lighthouse score. Choose a minimum age and style (yes/no, date of birth, or birth year), set country-specific rules, and show it site-wide or on select products. It remembers verified visitors, blocks under-age checkout, and keeps a privacy-safe audit log. No code required.
