Collected facts
Gatekeeper is an age verification app for merchants who sell age-restricted products like wine, spirits, tobacco, vape, and CBD. The gate runs entirely in the visitor's browser, which means dates of birth, IP addresses, and session data never reach our servers. Verified orders are tagged automatically in the merchant's admin, so the audit trail lives in Shopify where it belongs. Merchants choose from six polished templates and control exactly where the gate appears on their store.
