Privacy Policy

Last updated: October 6, 2026

The short version

We don't have accounts, we don't set cookies, and we don't collect personal data. Everything you type into our tools stays in your browser.

What we don't collect

• No accounts or signup. There is nothing to sign up for, so we hold no names, emails, or passwords.
• No cookies. We do not set any cookies or use browser storage to identify you.
• No form data leaves your browser. ZIP codes, room dimensions, appliance selections — every input is processed locally by JavaScript on your device. It is never sent to our servers or any third party.

What we do measure

We count page visits using Cloudflare Web Analytics, a privacy-friendly analytics service. It is cookieless and does not identify you personally. On each pageview it records the page URL, the referring page, and general browser/device characteristics (browser type, device type, country-level location) so we can see which tools people use. It does not track you across sites and cannot identify you as an individual.

Third parties

Our site is hosted on Cloudflare Pages. Aside from the analytics described above, we load no third-party scripts, fonts, or trackers.

Children

Our tools are general-audience utilities. We knowingly collect no data from anyone, including children.

Changes

If this policy changes, we will update the date above. Continued use of the site after changes means you accept the updated policy.

Contact

Questions about this policy: contact us through the site. There is deliberately no other way to reach us — we keep it that way so there is nothing to leak.
