Information we collect

The calculator tools are designed to run in your browser. The site does not need you to create an account to use the calculators.

Calculator inputs are used to display results in your browser. The site does not require names, account logins, or payment details to use the calculators.

The site may use basic analytics, server logs, advertising tools, or email contact. Those services may collect information such as browser type, device type, approximate location, pages visited, referral source, and ad interactions.

Advertising

This site may display ads from Google AdSense or other advertising partners. Google and third-party vendors may use cookies or similar technologies to serve ads, limit repeated ads, measure ad performance, and help prevent abuse.

Google may use advertising cookies to show ads based on a user's visits to this site and other sites. Users can learn how Google uses data and manage ad personalization through Google's advertising and privacy controls.

Cookies

The calculators do not require cookies to function. Analytics, server log, and advertising services may use cookies, web beacons, or similar technologies according to their own policies.

Most browsers let users block or delete cookies. Blocking cookies should not stop the calculators from working, but some advertising, analytics, or site features may behave differently.

Third-party services

Third-party services, including Google, may collect or receive information from this site and elsewhere on the internet and use that information to provide measurement services and personalized or non-personalized ads.
