Who we are
healthcalculators.co.uk is run by R&B Digital Ltd, a UK company. For anything about privacy, email hello@healthcalculators.co.uk.
What we collect
- What you type into a calculator: nothing. Every sum runs in your browser and is not sent to us. If we ever add a feature that needs to send data, we will update this page first.
- Cookies and storage: none. This version of the site sets no cookies and saves nothing in your browser, so there is no cookie notice to click.
- Analytics: none at present. If we switch on visitor statistics in future, we will use a privacy respectful tool and update this page before it goes live.
- Fonts and images are served from our own site, not a third party.
- If you email us, we use your address and message only to reply, and delete them when they are no longer needed.
- Our web host keeps standard server logs (such as IP address and pages requested) to keep the site secure and running.
Legal basis (UK GDPR)
We process the small amount of data above on the basis of legitimate interests: running a secure website and answering your emails. Where something needs your consent, we will ask first.
Your rights
You can ask to see, correct or delete personal data we hold about you by emailing hello@healthcalculators.co.uk. You can also complain to the Information Commissioner's Office (ICO).
Children
Some calculators are about pregnancy or family health. They are written for adults. Parents may want to help children explore health information online.
