Privacy Policy

The short version: this site has no accounts and no forms that send your figures anywhere. Every calculation happens in your own browser, and the numbers you type in are never collected, stored or shared by this site.

Last updated: 8 November 2026.

Calculations happen on your device

Each calculator does its maths locally, in the browser on your phone or computer, the moment you type. The pay figures, dates and other numbers you enter are not transmitted to us and are not saved anywhere by this site — when you close the page, they are gone. The “Print / save this result” buttons simply open your own browser's print view.

No accounts

There is nothing to sign up for and no sign-in for visitors. The only sign-in on the site is the admin area used by the people who run it.

Analytics

We use Google Analytics (GA4) to count visits and see which pages are used, in aggregate. It sets cookies such as _ga for that purpose. It never receives the figures you type into the calculators — those stay in your browser, as the section above explains. You can opt out with Google's Analytics opt-out add-on, or by blocking cookies in your browser.

Advertising

The site currently shows no adverts. If advertising is introduced later, third-party vendors, including Google, will use cookies to serve ads based on your prior visits to this and other sites, and you can opt out of personalised advertising at google.com/settings/ads and aboutads.info/choices. This page will be updated before any such change goes live.

Hosting and server logs

The site is hosted by Vercel. Like every web host, Vercel keeps standard server logs of requests (such as the page requested, the time, and the visitor's IP address) so it can deliver the site and protect it from abuse. Those logs are the host's operational records; we do not use them to identify or profile visitors.

Links to other websites

Pages here link to official guidance on GOV.UK. Once you follow a link and leave this site, that website's own privacy policy applies to anything you do there.
