Information processed by this site

This is primarily a static educational website. The interactive tools are designed to process entries in your browser and do not require an account. Standard web-server logs may record technical information such as IP address, browser type, requested page, timestamp and referring page for security and operational purposes.

Advertising and cookies

Pages on this site may use Google AdSense. Google and its partners may use cookies or similar technologies to provide, measure and personalize advertising where permitted. Consent choices may be presented in regions where required. You can review Google’s advertising and privacy information through Google’s own policies and controls.

Local browser processing

Tool entries are not intentionally submitted to a WRS database by these static calculators. Your browser, operating system, print-to-PDF feature, extensions or other services may still process information under their own policies.

International visitors

Privacy rights and advertising-consent requirements vary by jurisdiction. We aim to use reasonable privacy disclosures and applicable consent mechanisms but cannot provide legal advice about your individual rights.
