Privacy Policy

Effective date: July 16, 2026

Calculations stay on your device

Every calculator on this site runs entirely in your browser. The rates, hours, punch times, and other numbers you enter are processed locally on your device — they are never sent to our server and never stored by us.

Share links

Some calculators let you generate a share link so you can send your inputs to someone else, such as a manager or a coworker. These links encode your inputs in the URL fragment (the part after the # symbol). Fragments are not sent to our server when the link is opened, but anyone you share the link with can read the numbers encoded in it — so only share a link with people you're comfortable seeing those inputs.

Analytics

We use Google Analytics 4 to understand how many people visit the site and which calculators get used, so we can improve the tools. Google Analytics sets cookies and uses identifiers to distinguish visitors and sessions. It receives standard usage data (pages viewed, general location, device type), but it does not receive the numbers you type into a calculator — your calculator inputs stay in your browser and are never sent to analytics.

Advertising

This site currently shows no advertising. If that changes in the future, this policy will be updated first to describe what's shown and what data, if any, is involved.

Embedded calculators

If you encounter one of our calculators embedded on another website, that copy still runs the same client-side code — your inputs still stay in your browser — but your visit to that page is also subject to that site's own privacy policy, which we don't control.
