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

Advertising is currently paused and this application does not load the AdSense advertising script. If advertising is resumed after account and site review, Google may use cookies, local storage, device information, usage data, and approximate location to serve and measure ads. Calculator entries will not be included in advertising requests by this application.

Before advertising resumes, we must configure and verify the applicable consent mechanism, including a Google-certified consent management platform where required. An analytics preference is not advertising consent. You can review Google's advertising controls in My Ad Center.

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. Advertising is currently paused. You can remove calculator data with each calculator's reset control or by clearing this site's storage in your browser.
