Privacy Policy

Effective September 10, 2026.

Your calculator values

Calculations run in your browser. There are no accounts, and heart-rate values are neither stored remotely nor placed in share links. Form values live in page memory and reset when you leave or reload, except values you explicitly open in a shared pace URL.

Sharing

Copy and Share can include distance and finish time in a URL. Anyone receiving that link can read those values. URL query values may appear in browser history and ordinary hosting access logs when the shared page is requested. Do not include sensitive information in shared links.

Cookies, local storage, and hosting

The application does not use cookies or local storage. The hosting provider may process technical request information, such as IP addresses and browser details, for delivery and security. Private preview access may use the hosting provider’s own authentication cookies.

Analytics and advertising

Analytics and advertising are disabled in this release. No advertising or affiliate tracking is loaded. This policy must be updated before introducing a new data collection practice.
