Cookie Policy

What this site stores, and how to control it.

Local storage (not strictly cookies)

We save your recent calculations, chosen precision mode, and whether you have dismissed the cookie notice. This lives in your browser's local storage, is not sent anywhere, and is cleared when you clear site data or press the Clear button.

Analytics cookies

Google Analytics sets cookies to measure aggregate traffic and which tools get used. These help us improve the site and do not identify you personally.

Advertising cookies

When ads are enabled, advertising partners may set cookies to serve and measure advertising. You can manage these through your browser and through the partners' own controls.

Managing cookies

Every modern browser lets you block or delete cookies. Doing so will not stop the calculators from working, because the maths runs locally in your browser.
