Privacy Policy

Your calculator entries never leave your device. Times, breaks, and rates are processed in your browser and stored only in your browser's local storage so they survive a page refresh. We have no server that receives them.

What we do collect

Like most websites, we use standard analytics to understand aggregate traffic (pages visited, approximate location, device type). Advertising partners may set cookies to serve and measure ads; those partners publish their own privacy policies.

Your choices

You can clear saved calculator entries at any time with the “Clear all” button or by clearing your browser storage. Browser settings and extensions can block analytics and advertising cookies without affecting the calculators.
