Privacy Policy

The short version: your grades are yours. All calculations run locally in your browser.

What we collect

Nothing you type into any calculator is sent to us. Calculations happen entirely in your browser using JavaScript. We do not require accounts and do not ask for personal information.

Analytics and advertising

Like most websites, we may use privacy-respecting analytics to understand which pages are useful, and may display advertising served by third-party networks (such as Google). These third parties may use cookies as described in their own policies. You can opt out of Google advertising personalization at Google Ads Settings.

Changes

If this policy changes materially, the date below will be updated.
