Privacy Policy

Greatest Calculators is owned and operated by Greatest Ventures LLC. Privacy questions can be sent to questions@greatestcalculators.com.

Every calculation on this site runs in your browser. The values you type into a calculator are not transmitted to a server, not stored, and not logged. Closing the page discards them.

Even so, please do not enter sensitive personal, financial, health, legal, or account information into any calculator. A number you need to keep private is safer kept out of a web page entirely.

The site uses Google Analytics and Vercel Analytics to understand page views, calculator usage, errors, device types, and general traffic patterns. These services record standard technical information such as pages visited, referring site, browser and device type, approximate region, and timestamps.

Analytics data is used to decide which calculators to build and fix. It is not used to make individual decisions about visitors, and it is not sold.

This site uses Google AdSense to display advertising. Google is a third-party vendor that uses 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 to you based on your visit to this site and other sites on the internet. Third-party vendors and ad networks may also use cookies or device identifiers under their own privacy policies.

You can opt out of personalized advertising in Google Ads Settings, or opt out of a third-party vendor's use of cookies for personalized advertising at aboutads.info. You can also block or delete cookies in your browser settings; the calculators will continue to work normally.

The site is hosted on Vercel. Hosting, analytics, and advertising services necessarily receive standard technical information such as IP address, browser details, device type, pages visited, and timestamps in order to serve and secure the site.

This site is a general-audience reference tool and is not directed at children under 13, and Greatest Ventures LLC does not knowingly collect personal information from them.

Material changes to this policy are reflected in the last-updated date above. Questions about it can be sent to questions@greatestcalculators.com or through the contact page.
