Privacy Policy

The short version

• You don't need an account, and we don't ask for your name or email.
• The calculators run in your browser. We don't save the numbers you enter.
• We may show ads from Google AdSense and use privacy-friendly analytics. Both are explained below.

Information in the page address

When you use a calculator, your inputs are added to the page address so you can copy and share a result. If you open or share such a link, those numbers are part of the web address that is requested from our hosting provider, like any other link.

Information stored in your browser

• Theme preference: whether you chose light or dark mode.

We can't see or read this information.

Server logs

Our hosting provider, Cloudflare, processes standard request data (such as IP address, browser type and the page requested) to deliver the site and protect it from abuse. See Cloudflare's privacy policy.

Analytics

We may use Cloudflare Web Analytics, which counts page views without cookies and without building a profile of you.

Advertising

This site may display ads served by Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.

You can opt out of personalized advertising by visiting Google Ads Settings. To learn more, read how Google uses information from sites that use its services.

Where the law requires it (for example in the EEA and the UK), you will be asked for consent before personalized ads are shown.

Children

This site is not directed at children under 13, and we don't knowingly collect personal information from them.

Changes

If this policy changes, we'll update the date at the top of this page.
