Privacy

Calculations run entirely in your browser. The numbers you type are not sent to our servers.

Stored on your device

Your recently used calculators and favorites are kept in your browser’s local storage so you can find them again without an account. Clearing your browser data removes them.

Shareable links

Calculator inputs are placed in the page address so results can be shared. Anyone you send a link to can see those inputs.
