InCookie is a lightweight cookie consent manager deployed via Google Tag Manager. It supports GDPR, ePrivacy, and Google Consent Mode v2. No code changes needed on your site.

How long does setup take?

About 3 minutes. You add two tags in Google Tag Manager (consent defaults + banner), publish, and you are live. No backend or frontend changes required.

Yes, the basic version with InCookie branding is free. Premium features include white-label (no branding) and custom styling.

How does Google Tag Gateway help recover conversions?

Google Tag Gateway serves Google scripts (GA4, Ads) from your own domain via Cloudflare Workers. Ad blockers see first-party requests and let them through, recovering 10-22% of blocked signals.

What happens when a user rejects cookies?

GA4 switches to cookieless mode. It still collects session data without personal identifiers and uses conversion modeling to estimate the impact. Smart Bidding in Google Ads continues to work.

Which languages are supported?

Polish, English, German, Spanish, French, Ukrainian, Czech, and Slovak. The banner auto-detects the page language from the HTML lang attribute.

// why it matters

Numbers that hurt, and numbers that save.

Without a consent manager Google blocks signals. Without Google Tag Gateway, ad blockers do it. After deploying both - you recover what you can't see in reports today.

14%

average conversion gap

Ad blockers, Safari ITP and missing consent cut every 7th signal. These conversions exist - Google just doesn't count them.

recovery after GTG

Google scripts served from your domain via Cloudflare Worker. Ad blockers see a first-party request and let it through.

gzip, zero dependencies

CookieConsent v3 (MIT, Orestbida). Loads faster than a single OneTrust poll. No React, no jQuery.

// how it works

Four steps. Zero code on your site. Three minutes in GTM.

Deployment is two tags in Google Tag Manager - defaults and banner. No backend, no frontend, no waking up a developer at 10 PM.

Blocks by default

Consent Mode v2 starts in denied state. Google Tag holds cookies and signals until the user decides.

~50 ms

Shows banner

Box inline in the bottom left corner - doesn't block content, no wall to click through. Accept / Reject / Customize.

<1 LCP impact

Pushes to dataLayer

After choice - consent_update to GTM. GA4 and Ads tags fire only now, with the right flags.

Consent Mode v2

Remembers choice

Cookie cc_cookie (6 months) holds preferences. Re-prompt only when you change policy or categories.

// even when the user declines

Cookieless GA4 isn't empty.

Without marketing consent Google doesn't set cookies - but receives an ad_storage: denied signal. Consent Mode v2 then models conversions based on aggregates.

Cookieless ping instead of cookie - full session in GA4
