Checkpost decides whether to show the age gate in the visitor’s browser, using that visitor’s own cookie, so one cached copy of a page is correct for every visitor and there is no caching mode to configure. It has been tested with the page cache in W3 Total Cache. The popup can appear in the center of the screen, as a full-width bar at the top or bottom, or as a full-page takeover, and the rest of the page stays blocked in every position. You set it up with a live preview beside the settings, and it makes no external requests: nothing loads from a CDN or any other third party.

Visitors confirm their age with a Yes / No choice or by entering their date of birth. It suits liquor stores, vape and CBD shops, cannabis dispensaries, and adult content sites, with or without WooCommerce.

Core features

Yes/No confirmation, or full date-of-birth input via dropdowns or manual typed entry — your choice
Optional “Require Confirmation Checkbox” — an extra checkbox visitors must tick before the confirm/submit button becomes clickable, with an admin-editable label. Off by default; unchecked again on every fresh popup display; “No” always stays clickable regardless
Configurable minimum age (18, 21, or any value)
Visitors who don’t meet the age requirement see your underage message and stay blocked, or are redirected to a URL of your choice
Remembers verified visitors via a browser cookie (session, 30/90 days, 1 year, or a custom duration)
Gate the entire site, or only specific pages, posts and products
WooCommerce: gate specific product categories only (e.g. “Alcohol”, “Vape”) instead of the whole store
Works with or without WooCommerce installed
Enable/disable separately for mobile devices
Full design control: logo (with adjustable size), overlay style (none / solid / dark tint / blur), colors, font, custom heading & body text
Popup Position: classic centered popup, a full-width Top or Bottom Bar, or a Full Page takeover — the rest of the page stays blocked in every mode
Entrance Animation (None / Fade / Slide / Zoom) plays once when the gate first appears; Slide arrives from the matching edge for each position, Zoom is unavailable for the two Bar positions, and every option is automatically skipped for visitors with a reduced-motion preference set
Popup Width and Popup Padding presets (Small / Medium / Large / Extra Large each)
Popup background can be transparent (no card) instead of a solid color, for a fully custom look
One-click Popup Content Color presets (Dark / Light) fill in heading, body and button colors as a starting point — still fully editable, and never applied automatically by any other setting
Separate Button Hover Text Color, alongside Button Background/Text/Hover Background, for full control over the hover state
Font size presets (Small / Medium / Large / Extra Large) scale the heading, body text, buttons and date-of-birth fields together
Font can match your active theme automatically, or pick from a set of web-safe fonts
Optional background image behind the popup
Three starter templates (Minimal, Dark/Premium, Colorful) — fully editable after applying
Live preview in the admin settings page
Translation-ready
Runs entirely on your own server, with no external requests
