Saving a setup uses browser local storage. Clearing site data removes the saved setup. A copied scenario link contains the model choices and entered numbers in its URL fragment; anyone you share that link with can read those values.
Hosting and external sites
The hosting provider processes ordinary web requests and may retain operational logs under its own policies. Manufacturer and retailer links take you to sites with their own privacy practices.
Retailer links and AI
Amazon links include an affiliate tracking ID. The destination may use its own cookies and account services. This website does not read your Amazon account or purchase history.
AI chat is not enabled in this release. Calculator inputs are processed on your device and are not sent to an AI provider.
