Privacy

Last updated October 27, 2026

heatpumpratings.online is a reference site maintained by Emma Wilson. It has no accounts and no forms that store data. It sets no cookies, runs no analytics and, at present, shows no advertising.

Hosting and delivery

The site is hosted by Contabo GmbH, Aschauer Straße 32a, 81549 München, Germany. Requests reach it through Cloudflare, which processes the IP address and user agent of each request in order to deliver the site and protect it from abuse.

Server logs

The web server keeps access logs with the IP address, time, requested URL and user agent of each request. They are kept for up to 14 days for security and operation and are then deleted. They are not used to build profiles and are not shared, except where the law requires it.

Your browser

The side-by-side tool can remember your last comparison in your own browser's local storage. That value never leaves your device, and you can clear it at any time in your browser settings. The cold finder keeps its settings in the page address only.
