Privacy Policy
Short version: the calculators run in your browser and we don't collect what you type.
Last updated: October 14, 2026
This Privacy Policy explains how ClockMath ("we", "us") at clockmathtools.com handles information when you use this website.
Information you enter in the calculators
The calculators run entirely in your web browser. Times, rates and other values you type are not sent to or stored on our servers. The Timesheet Calculator saves your entries in your browser's local storage so they are still there when you return on the same device. You can remove them at any time with the "Clear all" button or by clearing your browser data.
