Privacy notice

Calculator inputs

The figures you enter into a calculator are processed in your browser. They are not transmitted to us and are not stored on a server.

Analytics

We record non-identifying usage events — for example that a calculator was opened or completed — together with a random session identifier held in your browser. We do not collect names, addresses, incomes or any figure you type.

Advertising

This site is built to carry display advertising from Google AdSense. When it is enabled, Google acts as a third-party vendor and may use cookies or similar technologies to serve and measure ads based on your visits to this and other sites. Google's use of advertising cookies is described in its privacy and terms, and you can manage personalisation at adssettings.google.com. Nothing you enter into a calculator is shared with advertisers.

Local storage

We use your browser's storage for a random session identifier and to recognise a return visit. See our cookies and storage page.

Your rights

Under UK GDPR you have rights over personal data we hold about you. Because we avoid collecting personal data through this site, in most cases we hold none. If you have emailed us, we hold that correspondence. Contact us to request a copy or deletion.
