Privacy Policy

Last updated: October 8, 2026

This policy explains what information CalcWise ("we", "us") collects when you visit https://calcwise.crushjs.com, and how it is used.

Calculator inputs

All calculations run locally in your web browser. The numbers you type into our calculators are not sent to, stored on, or seen by our servers.

Preferences stored on your device

If you choose a color theme, language or currency, we remember that choice in your browser's local storage so the site looks the way you left it. This information stays on your device and is never sent to us. You can clear it at any time in your browser settings.

Information collected automatically

Like most websites, our hosting provider may log standard technical information such as IP address, browser type, referring page and time of visit. We use this only to keep the site secure and working, and to understand overall traffic.

Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
