Privacy Policy

Last updated: August 2026

This Privacy Policy explains how Calc-Tool (“we”, “us”) handles information when you use our website.

Information we collect

Calculator inputs. The numbers you type into our calculators are processed entirely in your browser to produce a result. We do not transmit or store them on our servers.

Usage data. Like most websites, we may use analytics to understand aggregate, anonymized traffic — such as which pages are popular and what device types are used.

Cookies and advertising

We use advertising to keep the site free. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites.

• Google’s use of advertising cookies enables it and its partners to serve ads based on your visits 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 some third-party vendors’ use of cookies at aboutads.info/choices.

Analytics

If enabled, Google Analytics collects anonymized data such as pages viewed and approximate location (by region), governed by Google’s Privacy Policy.

Your choices

You can disable cookies in your browser settings and use browser privacy tools at any time. Doing so will not affect the calculators, which work without cookies.

Children’s privacy

This site is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.

Changes

We may update this policy from time to time. Material changes will be reflected by the “last updated” date above.
