Six calculators, all free and complete. No email address, no account, no upsell in the middle. Nothing you type is saved to your browser or sent to a server.

Because a calculator that holds its answer hostage isn't a calculator. Each of these does the whole job on the page, and then tells you honestly what it can't do — which is carry the numbers into next month.
They also store nothing. No browser storage, no server, no analytics on what you typed. That's the same principle Alfie is built on, and it would be odd to run these any other way.
