Privacy Policy

Last updated: 2026-08-24

Overview

CalculationPro ("we", "us") respects your privacy. This policy explains what information is collected when you use this website and how it's used.

Calculator data

Numbers you enter into our calculators are processed entirely in your browser using JavaScript. We do not collect, store, or transmit the values you type into any calculator to our servers.

Cookies & advertising

This site displays advertisements served by Google AdSense. Google and its partners may use cookies, web beacons, and similar technologies to collect information about your visits to this and other websites in order to provide advertisements about goods and services of interest to you. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and/or other sites on the Internet.

You may opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of a third-party vendor's use of cookies for personalized advertising by visiting www.aboutads.info.

Local storage

Separately from advertising cookies, this site itself sets no cookies. It uses your browser's local storage for two functional purposes only: remembering your light/dark theme choice, and caching currency exchange rates for up to 12 hours so calculators with a currency converter don't have to re-fetch rates on every page load. Neither is used for tracking, and neither is shared with any third party. You can clear this data anytime by clearing your browser's site data for calculationpro.com.

Analytics

We may use standard web analytics tools to understand aggregate traffic patterns (e.g. which pages are visited, general geographic region, device type). This data is anonymized and used only to improve the site.

Third-party links

Our site may link to third-party sites. We are not responsible for the privacy practices of those sites.

Children's privacy

This site is not directed at children under 13, and we do not knowingly collect personal information from children.

Changes to this policy

We may update this policy from time to time. Continued use of the site after changes constitutes acceptance of the updated policy.
