Home Lab 21 is a simulation that runs in your browser. There is no account, no sign-up, and no server that stores anything about you. This page tells the whole story of the one thing we do ask.
We ask first
On your first visit, a small banner asks whether we may use cookies. Nothing that needs your permission runs before you answer. Saying no and saying yes are equal choices — no dark patterns, no nagging.
Nothing breaks if you say no
The simulation does not depend on your answer. Say no and the page works exactly the same: every door, window, appliance and map tool behaves identically. The only thing kept after a no is the banner's own small cookie that remembers your answer, so we do not ask again on every visit.
Why we ask at all
When you say yes, the page records anonymous session replays with Microsoft Clarity: which controls get clicked, where people scroll, where they hesitate. These replays exist for one purpose — to show us where the page confuses people, so we can fix it. They are not used to identify you and they are not sold or shared for advertising.
What runs on the page
-
Microsoft Clarity — session replays. Only with your yes. It
uses two cookies on this site (
_clckand_clsk) to tell one session from another. Say no and it does not run and those cookies are removed. - Cloudflare Web Analytics — an anonymous visitor counter with no cookies at all. It counts visits and countries and nothing about you personally, which is why it needs no permission.
-
The consent cookie (
cc_cookie) — remembers your answer for one year. After a year the banner asks again.
Where you are decides the start
Before you answer, your approximate region — read from the connection itself, the way any website knows roughly where a visitor comes from — decides the starting state. Visitors from countries whose law says ask-first (the EU and its neighbours) get no recording until they say yes. Everywhere else, recording starts right away and stops the moment you say no. Your browser's location is never asked for.
