Privacy Policy
Last updated: 25 July 2026
Overview
Calculio (https://calculio.co.uk) is designed to be used without creating an account or submitting personal information. This policy explains what limited data is collected when you use the site and how it's handled.
Calculator inputs
Figures you enter into any calculator — such as a salary, property price or date of birth — are processed entirely in your browser to produce a result. This data is not transmitted to, stored on, or logged by our servers.
Analytics and cookies
We may use privacy-conscious analytics to understand how the site is used in aggregate (such as which pages are visited and how often), to help us improve the site. Any such analytics do not identify you personally. If we introduce cookies for analytics or functionality in future, we will update this policy and, where required, ask for your consent.
Contact form
If you use the contact form, the name, email address and message you provide are used only to respond to your enquiry. We do not sell, rent or share this information with third parties for marketing purposes.
Third-party links
Some pages link to external sites, such as gov.uk or the NHS website, for further information. We are not responsible for the privacy practices of external sites you visit from a link on Calculio.
Your rights
If you have any questions about this policy or how your information is handled, please get in touch via our contact page.
Changes to this policy
We may update this policy from time to time. Any changes will be posted on this page with an updated revision date.
