Calculator inputs
Your room, product, usage and price inputs are calculated in your browser. Cool Cost Lab does not send or store those values on its server.
Saved preference
Cool Cost Lab does not store any preference on your device — no cookies, no local storage. Every visit starts fresh.
Anonymous tool-use measurement
Cool Cost Lab uses Cloudflare Workers Analytics Engine to count which calculator was used and which market edition served it. It does not record calculator inputs, prices, room details, a user ID, or the contents of any form. The same calculator is counted at most once per page document.
Advertising
The public AdSense publisher identifier and ads.txt file are present for site review, but advertising units remain disabled until Google approves the site. If advertising is activated later, this notice will be updated before the ad units are deployed.
