Your calculator inputs stay in your browser.
One Clear Tool is built to give quick estimates without requiring an account or sending calculator values to an application server.
Calculator data
The published calculators currently perform their calculations in your web browser. The calculator pages do not submit the numbers you enter to a One Clear Tool application server.
Accounts and sign-up
No One Clear Tool account is required to use the public calculators.
Analytics and third-party scripts
The current published calculator pages do not include a One Clear Tool analytics script. The site may still be delivered through hosting, DNS, browser, or network providers that process standard request information under their own policies.
External links
Some pages link to external services, including Buy Me a Coffee. When you follow an external link, that service's privacy practices and terms apply.
Changes
If One Clear Tool later adds accounts, analytics, server-side processing, or other data collection, this page should be updated to describe that change.
