How CalcWise handles your information — in plain English.
The short version: CalcWise does not collect, store, or sell your personal data. All calculations happen directly in your browser. We never see your numbers, inputs, or results.

By using CalcWise, you agree to the terms described in this Privacy Policy. If you do not agree, please discontinue use of the Site.
CalcWise is a client-side web application. This means all calculations are processed locally in your browser — your inputs are never transmitted to our servers.
