Privacy Policy

Calculator inputs

Speed, pace, incline, weight, and duration are processed only in your browser. The calculator does not send or save those values, and it has no account or database.

Analytics status

Google Analytics is configured but does not load until you choose Allow analytics in the on-page control. Before that choice, the site sends no Google Analytics request and sets no Google Analytics cookie. Calculator values are never analytics events or event parameters. Google Signals and advertising-personalization signals are disabled.

Cookies and hosting

The site stores your analytics choice in browser localStorage. If you allow analytics, Google Analytics may set first-party _ga cookies and process ordinary page, browser, device, and approximate-location information. Use Analytics settings to change the choice. The hosting provider may separately process ordinary request information, such as IP address, browser type, and request time, to deliver and secure the static files.

Retention and contact

Treadmill Lab retains no calculator submissions. A public privacy inbox is not yet configured; material changes to analytics or data handling will be recorded on this page with a new update date.
