Privacy Policy
Calculator inputs are designed to be processed in the browser and do not require an account or server-side storage of the bill amount.
Optional analytics and advertising technologies are used only when configured and, where required, after the appropriate consent choice. Necessary storage may be used to remember privacy preferences.
This policy is reviewed whenever data-handling practices, analytics, advertising providers, consent requirements, or other material privacy practices change.
