Privacy Policy

Calculator data

Courses, grades, credits, theme preferences, and calculator settings are stored in your browser's local storage. They are not sent to our server when you use the calculators.

Imports and exports

Import and export actions are processed in your browser. You control any JSON or CSV files that you download or choose to import.

Analytics

Google Analytics loads by default to measure site usage unless you turn it off or your browser sends Global Privacy Control or Do Not Track. Google may process device, usage, and approximate location information under its own privacy terms. Calculator course data is not included in analytics events by this application.

Advertising

This site uses Google AdSense to show advertising. When ads are served, Google may use cookies, local storage, device information, usage data, and approximate location to serve and measure ads. Calculator entries are not included in advertising requests by this application.

When ads are shown, third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.

You may opt out of personalized advertising by visiting Google's Ads Settings (also available in My Ad Center). You can also opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info. Learn more about how Google uses information from sites that use its services.

Ads load only after the applicable consent mechanism, including a Google-certified consent management platform where required, has recorded your choice. An analytics preference is not advertising consent.

Cookies

This site stores calculator data in local storage rather than cookies. Google Analytics sets its own cookies (such as _ga) to distinguish visits. When ads are served, Google may set advertising cookies as described above. You can block or delete cookies in your browser settings; the calculators keep working without them.

Children

The site is intended for students and families planning coursework and applications. We do not knowingly collect personal information from children under 13, and the calculators do not require an account or any personal details.

Your choices

You can change your analytics choice at any time with “Analytics preferences” in the footer. Turning analytics off disables future analytics collection and removes analytics cookies that this site can access. Global Privacy Control and Do Not Track signals keep analytics disabled. Where advertising consent is requested, you can change that choice through the consent message. You can remove calculator data with each calculator's reset control or by clearing this site's storage in your browser.
