Privacy Policy

Room sizes, system ages, repair quotes and every other input are calculated in your browser and are not sent to our server. If you use "Share link", those inputs are placed in the link itself so the person you send it to sees the same result.

We store your light or dark theme choice in your browser (localStorage). It never leaves your device and you can clear it in your browser settings.

Like any website, our web host and our content delivery and security provider (Cloudflare) process technical data such as your IP address, browser type and the pages requested, to deliver the site and protect it from abuse. Our fonts are served from our own server, so loading them shares nothing with third parties.

This site uses Google AdSense to show ads. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.

• You can opt out of personalized advertising in Google Ads Settings.
• You can opt out of some third-party vendors’ use of cookies for personalized advertising at www.aboutads.info.
• Learn more in how Google uses information from sites that use its services.

Where the law requires it (for example in the European Economic Area, the United Kingdom and Switzerland), you are asked for consent through a Google-certified consent message before cookies are used for personalized ads, and you can change your choice at any time.

If we enable Google Analytics, it will collect aggregated, pseudonymous usage data (pages viewed, device type, approximate region) to help us improve the tools. We do not use it to identify you. You can block it with the Google Analytics opt-out add-on.

You can block or delete cookies in your browser settings; the tools keep working without them. We do not sell personal information. Depending on where you live (for example California or the EU), you may have rights to access or delete personal data; write to [email protected] and we will respond.

If you write to [email protected], we use your email only to reply and keep the message as long as needed to handle it.

The site is meant for adults and is not directed to children under 13.

The whole site is served over HTTPS, so the connection between your browser and the site is encrypted. Because we do not collect accounts or tool inputs, there is no database of personal information to leak.

We will update this page and its date if anything changes. Questions: [email protected].
