What is kept in your browser

The owner tools keep three fields — your name, company and work email — in your browser’s local storage so they can recognise you between visits, and checklists keep your progress locally. Nothing is sent to us unless you submit a form. You can clear all of it by clearing site data for this domain, or by signing out on the account page.

Share links

Calculator share links encode your scenario inputs in the page address. Anyone with the link can load those assumptions — share them only with people you trust.
