See what a cookie banner actually does
Most people click the cookie box away without knowing what it controls. Here is a banner with its cards on the table. Click around the mini-shop, make your choice in the banner at the bottom, and watch in real time which data gets sent, where it goes, and what gets stopped. It is all simulated. Nothing is sent for real.
Click in the shop
Try the buttons right away. Before you choose anything, everything but the necessary is blocked.
Make your choice in the banner
The banner sits at the bottom of the page, just like on real sites. Allow everything, reject everything, or choose category by category.
See what happens
The tools, the tech, and the log show in real time what gets sent and what gets stopped.
👇 Start by making your choice in the cookie banner at the bottom of the page. Try the shop first if you like, and you’ll see that everything but the necessary is stopped.
§ 01 · The shop
A pretend shop. Every click is the kind of event real sites measure.

⚠ Cautious mode is on. Nothing but the necessary gets through until you make a choice in the banner.
§ 02 · What the site knows about you
The human answer. What your choices actually mean.
💬 What just happened?
Click something in the shop and I’ll tell you exactly what happens to the data.

For anyone who knows their way around GTM. The exact signals the systems receive.
The consent gate
This is how the choice would be saved in the browser (localStorage, the key cookie-consent):
no choice saved yet
§ 05 · The event log
Every event, where it went, and what was stopped.
No events yet. Click around the shop above.
We use cookies
We want to measure how the site is used and to be able to show relevant ads. Necessary cookies are always on; the rest is up to you.

The same principle as in the real build
The data flow is real, only the recipients are unplugged
What you see above is the same data flow as on a real site. The events, the consent gate, and the signals all work the way they would in production. The only thing unplugged is the recipients. Wire the flow up to real systems like GTM, GA4, and Meta Pixel, and the same logic runs live.
Built from scratch instead of a bought service. Full control over the look, the words, and the behavior.
The choice actually controls things. Scripts are blocked before they load, not after.
Consent Mode v2 steers Google’s tools, and Meta, TikTok, and LinkedIn get their signals directly, with no middleman.
The write-up of the real build will be back shortly.
