Klify - Verify Age & Terms
Verify age and terms before shoppers reach your storefront
Age gates, date-of-birth checks, and terms acceptance — without coding.
Overview
Klify – Verify Age & Terms helps merchants restrict access to age-sensitive stores and products, stay compliant with local age rules, and present a fully customizable storefront age popup. Choose Yes/No or date-of-birth verification, apply country-specific minimum ages, remember verified visitors by session or cookie, require Terms & Conditions on the popup, cart, login, register, contact, and checkout (Plus), and brand the gate to match your store.

01
Flexible verification: 1-click or birthdate entry
Dual workflows for low-friction entry or strict compliance — with dynamic {minAge} messaging and clear decline handling.
Fast 1-click Yes/No gate
Single-click confirmation with Accept and Decline buttons. Ideal when shoppers only need to confirm they meet the minimum age.
Exact date of birth (DOB) picker
Require month, day, and year of birth, then automatically check the calculated age against your minimum.
Global & dynamic minimum age
Set a default baseline age and use the {minAge} token in titles, body text, buttons, and denial messages so copy updates with location or product context.
Disagree / decline actions
Keep the modal open with an inline denial message, or instantly redirect underage visitors to an external URL (for example a legal warning page).
02
Multi-targeting for age popups
Trigger verification storewide, or isolate it to the pages and products that need it.
Storewide or page-level
Show the gate on all pages, product pages, collection pages, cart page, and cart drawer.
Specific products & collections
Limit campaigns to selected products or collections instead of the entire catalog.
Product & customer tags
Target tagged items such as age-restricted, alcohol, or 21+ so only the right SKUs trigger the gate.
03
Seamless terms everywhere: popups, cart & checkout
Collect consent at every critical touchpoint — in the age gate popup, slide-out cart drawer, and cart page — with verification logged on the order.
Popup, cart page & cart drawer
Show Terms acceptance in the age gate and again on the cart page or cart drawer before checkout.
Logged on the order
Verified age and timestamp are written to order notes and attributes so you can audit consent later.
04
Automatic geo-targeting & country-specific limits
Automatically detect shopper location by IP and enforce legal age requirements per country.
IP-based detection
Identify shopper location via Shopify context and IP geolocation so the right minimum age applies automatically.
Country-specific overrides
Set location-aware limits (for example US 21, Canada 19, Japan 20) while keeping a storewide default baseline.
Dynamic {minAge} messaging
Titles, body text, buttons, and denial messages update with the evaluated minimum age for the visitor’s location.
05
Enforce legal agreements & privacy policies
Require an explicit Terms of Service checkbox, style the agreement, and choose where it appears — including Login, Register, and Contact-Us.
Mandatory terms checkbox
Require customers to check Terms of Service before verifying age or continuing, with customizable label and modal policy content.
Terms acceptation target
Independently display terms on custom pages — Login, Register, and Contact-Us — as well as the age popup, cart, and cart drawer.
Shopify Plus checkout
On Shopify Plus, add terms and conditions validation on the checkout page.
Policy display & styling
Open terms in a non-disruptive popup and match checkbox colors, fonts, borders, and presets to your brand.
06
Brand customization with Studio
Match your brand with themes, colors, logos, button layouts, entrance motion, mobile controls, and Custom CSS.
Themes, colors & backgrounds
Use built-in presets or custom solid, gradient, image, and pattern backgrounds with blur, opacity, and 9-point popup positioning.
Logo & button studio
Upload a store logo, set width and alignment, and fully style Accept/Decline buttons — shape, colors, stacked or side-by-side, width, and radius.
Mobile responsive control
Independent mobile typography scaling, image placement (top header, full background, or hide), and button alignment.
Entrance FX & Custom CSS
Add entrance animations and delays, then override fonts, shadows, borders, and glassmorphism with the Custom CSS editor (Pro).
07
Smart session & cookie lifetime controls
Choose whether to remember verified customers for seamless repeat shopping or re-verify every session for strict legal compliance.
Custom cookie lifetime
Remember verification for 1 to 365 days so returning shoppers are not blocked on every visit.
Session-based mode
Re-check when the visitor closes their browser tab for stricter compliance.
Friction-free returning shoppers
Balance seamless shopping with the audit posture your category requires.
