Calculator inputs

This version calculates results in your browser. WattWorth does not send calculator values to a server or save them in cookies or local storage. Reloading the page resets the inputs.

Analytics and advertising

This version does not load advertising, analytics, external fonts, or third-party tracking scripts. The site is delivered through OpenAI Sites and Cloudflare. These providers may process access information such as IP addresses, browser details and request logs, and set security cookies to deliver the site and protect it from automated abuse. Calculator inputs are not included in these requests.

External resources

Source links take you to other websites with their own privacy practices.

Future changes
