Privacy Policy

Calculator inputs

The numbers you type into any calculator on this site are processed entirely in your own browser. They are not sent to a server, not stored, and not visible to anyone operating this site.

Analytics

This site may use analytics software to understand aggregate traffic — which pages are visited and roughly where visitors come from. This data is aggregated and is not used to identify individuals.

Advertising

This site may display advertising served by third-party ad networks, including Google. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on visits to this site and other sites on the internet.

Users may opt out of personalized advertising by visiting Google's Ads Settings. Users may also opt out of third-party vendors' use of cookies for personalized advertising through www.aboutads.info.

Third-party ad networks may collect information such as IP address, browser type, pages viewed, and time spent, subject to their own privacy policies.

Affiliate links

Some pages may contain affiliate links. If you follow one and complete an action with that company, this site may earn a commission at no additional cost to you. Affiliate relationships never change a calculator's math or its verdict.

Your choices

You can block or delete cookies in your browser settings at any time. Doing so does not affect the calculators, which work without them.

Children

This site is intended for general audiences and is not directed to children under 13, and does not knowingly collect personal information from them.

Changes

This policy may be updated from time to time. The date at the top reflects the most recent revision.
