Calculation and browser storage
All calculator arithmetic run in the browser. Values are not inserted into URLs, sent to an API, or reported to an analytics or crash-reporting service by this application. No location lookup, bank connection or account login is implemented.
This application does not write your inputs, lists, settings or history to localStorage, sessionStorage or cookies. They remain in the page's memory and may be retained by your browser's own page restoration. Use the form's Reset button to clear current inputs.
Delivering the site and receiving email
Pages are delivered through Cloudflare (Workers / CDN). A visit involves network requests that can include an IP address, requested resource and browser information. An email to info@heatindexcalculator.org is forwarded to flemming@domainfirm.io once Email Routing is active for the zone. That message contains your address and whatever you choose to include.
The site serves its own HTML, styles, scripts and Inter font files. It includes no advertising, third-party fonts or runtime CDN script dependencies from other vendors. Following an external source link or choosing an email or telephone link leaves this site and is subject to the receiving service's practices.
