About Calcuplay

What you'll find here

Tools for calculations a search engine doesn't always do: math, dates and times, health, cooking, building materials, everyday life, tech, units and currencies. Each tool shows its formula, an example and, when figures come from outside, their source.

Who runs the site

The site is run by an independent publisher based in Quebec, Canada. It is not affiliated with any manufacturer, brand or organization cited in the tools.

Our principles

• No account: every tool is free and ready to use.
• Your calculations run in your browser; the Privacy page explains exactly what is kept.
• No invented official figures: every outside figure is checked against its source, which is cited.
• No ads and no visitor analytics for now. If that changes, the Privacy page will be updated first.
