Privacy Policy

Last updated: July 11, 2026

Calculator Euphoria ("we", "this site") publishes free calculator tools at calculatoreuphoria.com. This policy explains what data is and isn't collected when you use the site.

Calculator inputs

Every calculator on this site runs entirely in your browser using JavaScript. The numbers you type — income, weight, age, grades, loan details, or anything else — are processed locally on your device and are never sent to us or to any server. We have no way to see what you calculate.

Analytics

We may use a privacy-respecting analytics service to understand which calculators are popular and to fix broken pages. This tells us aggregate information such as page views and general location (country/region) — it does not identify you personally, and it never includes anything you typed into a calculator.

Advertising and cookies

This site may display ads through third-party ad networks (such as Google AdSense) to keep the calculators free. These networks may use cookies or similar technologies to serve relevant ads based on your visit to this and other sites. You can opt out of personalized advertising through Google's Ads Settings or via the Digital Advertising Alliance.

Local storage

We use your browser's local storage to remember one preference: light or dark theme. This stays on your device and is never transmitted anywhere.

Third-party links

Some pages may link to outside resources for further reading. We aren't responsible for the privacy practices of other websites.

Children's privacy

This site does not knowingly collect personal information from children under 13.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new "last updated" date.
