Privacy
We collect as little as a website can.
Last updated 29 October 2026
Calculators
Calculators run entirely in your browser. The numbers you type are not sent to us or stored anywhere.
What is stored on your device
If you switch between light and dark colours, that choice is saved in your browser’s local storage so the next page matches. Nothing else is stored.
Hosting and analytics
The site is served by Cloudflare, which processes standard request data such as IP addresses to deliver pages and protect against abuse.
We do not run analytics, advertising or tracking scripts.
Links to providers
When you follow a link to a provider, its own privacy policy applies from that point.
