Privacy

Short version: Athletics Utilities does not track you. There are no cookies, no analytics, no advertising, no third-party tracking scripts, and no account or signup. Anything you type into a calculator stays on your device.

What is stored on your device

The calculators use your browser's localStorage and sessionStorage to remember your preferences and recent calculations. This data is created and read only by your browser on this site — it is never sent to the maintainer of this website or to any third party.

Preferences (sessionStorage, cleared when you close the tab): the gender selection, the calculator mode and sub-mode toggles on the Pace, Time, and Age calculators, and the open/closed state of collapsible sections.
Calculation history (localStorage, persists until you clear it): the most recent ten calculations on each of the Pace, Time, and Age calculators.

You can clear this data at any time by clearing site data for athleticsutils.com in your browser settings, or by using the in-app history controls on each calculator.
