How ShiftCalculator.com collects, uses and protects information when you visit the site and use the calculators.
The short version: Calculations happen entirely in your browser. ShiftCalculator.com does not collect, transmit or store your shift data, hourly rate or any inputs. We use standard web analytics to understand which pages are useful, and may serve advertising via Google AdSense. You can email [email protected] with any privacy question.
This Privacy Policy explains how ShiftCalculator.com ("ShiftCalculator.com", "we", "us" or "the site") handles information when you visit https://shiftcalculator.com and use the calculators or read the guides. By using the site you agree to this policy. If you do not agree, please do not use the site.
The data you type into the calculator never leaves your browser. That includes:

The site may use Google Analytics to understand traffic patterns. Google Analytics uses cookies and may collect IP address and usage data. You can opt out by installing the Google Analytics Opt-out Browser Add-on.

We take reasonable measures to protect the site and any data we hold:

Some browsers send a "Do Not Track" signal. There is no industry consensus on how to respond to it, and the site does not currently respond to DNT signals. Because the calculators do not track you across websites or store personal data, DNT has limited impact on your privacy when using ShiftCalculator.com.
The site contains links to third-party websites. We are not responsible for their content or privacy practices. Please review the privacy policy of any external site before sharing information with it.
