Calculator information

Calculations run in your browser. We do not require you to create an account or submit your name, employer, employee number or pay stub. When you choose “Save on device,” the information is stored in your browser's local storage on that device.

Google Analytics

We use Google Analytics 4 to understand general website activity, such as which pages are visited, device and browser categories, approximate location and how visitors move through the site. Google Analytics may use cookies or similar technologies after you allow analytics. We use this information in aggregate to improve our calculators, schedules and guides. We do not send names, employer details, pay rates or saved calculator entries to Google Analytics.

Advertising

We may use Google AdSense in the future. Advertising providers may use cookies or similar technologies to measure performance, prevent fraud and show advertising, subject to their policies and your consent choices where required. This policy will be updated when advertising is activated.

Information automatically received

Like most websites, hosting and security systems may process basic request information such as browser type, device type, approximate location derived from an IP address, pages requested and timestamps. This information is used for security, reliability and aggregate measurement.

Your choices

You can allow or decline analytics through the notice shown on the site. Your choice is stored on your device. You can reset it by clearing this site's local storage or cookies in your browser. You can also clear estimates saved on your device using your browser's site-data controls.

Children

The service is intended for a general working-age audience and is not directed to children under 13.

Contact

Our Contact page explains the information that is useful when reporting a calculation, factual or technical issue. A dedicated support email will be published there when it is active.
