Privacy Policy

The short version

NHS Calculator is designed to respect your privacy. Calculator results are computed in your own browser, and the health figures you enter are not sent to, or stored by, our servers.

Information we collect

We collect very little. Like most websites we may use standard technical logs and cookies (for example cache-management cookies from our hosting) to operate and secure the site and to understand broad, anonymous usage patterns. Where analytics are used, data is aggregate and anonymised where possible.

Contact forms and email

If you email us, we use your details only to respond to your enquiry. We do not sell personal data, and we do not share it except where required by law.

Your rights

Under UK data protection law you have rights to access, correct or delete personal data we hold about you, and to complain to the Information Commissioner’s Office. To exercise these rights, contact us at contact@nhs-calculator.co.uk.
