Cookie Policy
This page explains the limited browser storage used for privacy choices and optional analytics.
Essential storage
Local storage remembers your consent choice so the notice does not reappear on every visit. Calculators do not require a profile or sign-in.
Analytics cookies
If you allow analytics, Google Analytics may use cookies such as _ga to distinguish visits statistically. Calculator values are not included in analytics events.
Manage your choice
You can reject analytics without affecting the tools. Use the cookie settings button to revisit your choice, or remove site data in your browser.
