Privacy Policy

Short version: the numbers you type into our calculators never leave your device. We use Google Analytics to understand how many people visit and which pages they use.

Last updated: 7 October 2026

Calculator inputs

All calculations run in your browser. The amounts, rates and other values you enter are not sent to our servers. To save you retyping, your last inputs and your light/dark theme choice are stored in your browser's local storage on your own device. You can clear them anytime by clearing this site's data in your browser settings.

Analytics

We use Google Analytics to measure visits: for example which pages are viewed, roughly where visitors are from, what device and browser they use, and how they arrived. Google Analytics uses cookies and similar technology to collect this, and Google processes it under its own policies. We use this information only in aggregate, to improve the site. You can learn more at How Google uses information from sites that use its services, and you can opt out with the Google Analytics opt-out browser add-on.

Advertising

We may show ads in the future, for example through Google AdSense. If we do, third-party vendors including Google may use cookies to show ads based on your previous visits to this and other websites. You can turn off personalised ads at Google Ads Settings, or visit aboutads.info to opt out of some third-party vendors' cookies. We will update this page if ads are added.

Hosting and security

The site is hosted on Cloudflare, which may process technical data such as IP addresses to deliver pages and protect the site from abuse.

Emails you send us

If you email us, we use your email address and message only to reply. We don't sell or share them.
