The calculators themselves collect nothing — the numbers you enter stay in your browser and are never transmitted or stored. This page covers the standard data that advertising and analytics services collect automatically when you visit any website, including this one.
This site may display ads served by Google AdSense and other third-party advertising networks. These networks may use cookies, device identifiers, and similar technologies 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 visit to this site and/or other sites on the Internet. You can opt out of personalized advertising by visiting Google's Ads Settings, or generally at aboutads.info/choices.
For more on how Google uses information from sites that use its services, see How Google uses information from sites or apps that use our services.
Visitors from the European Economic Area, the United Kingdom, and Switzerland are shown a consent message, powered by Google's certified consent management platform, before personalized ads or related cookies are used. You can change your choices at any time through that message.
We may use analytics services (such as Google Analytics) to understand overall traffic patterns — for example, which calculators are used most and which pages people visit. This data is aggregated and is not used to identify you personally.
We do not require account creation, and we do not ask for your name, email, or financial account information to use any calculator. Values you enter into a calculator are processed locally in your browser and are not saved by this site.
Most browsers let you block or delete cookies through their settings. Blocking cookies may affect how ads are shown but will not affect any calculator's functionality, since all calculations happen locally.
We may update this policy from time to time. Changes will be posted on this page with an updated effective date.
