Privacy policy

Last updated November 11, 2026.

The short version

The numbers you type into our calculators stay in your browser. We do not receive, store or sell them.

Information we collect

  • Calculator inputs: processed only on your device. If you copy a share link, the inputs are placed after the “#” in that link so the person you share it with sees the same result. That part of a link is never sent to our server or to analytics, and we do not keep a copy.
  • Analytics: we may use Google Analytics to count visits and see which pages are used. It collects device, browser and approximate location data and uses cookies. We do not send calculator amounts to analytics.
  • Email: if you write to us, we keep your message to reply.

Advertising

We may show ads served by Google. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google’s use of advertising cookies enables it and its partners to serve ads based on your visits to this site and/or other sites on the Internet. You can opt out of personalized advertising in Google Ads Settings or at aboutads.info. See how Google uses information from sites that use its services.

Cookies and consent

For visitors in the European Economic Area, the UK and Switzerland, analytics and advertising cookies are off by default and are used only after you agree in a consent message. If we show ads, that message is provided through a Google-certified consent platform, and you can change your choice at any time from the link it adds to the page. You can also block cookies in your browser settings.

Residents of California and other US states with privacy laws can opt out of the use of their information for personalized advertising through the privacy message shown on this site when ads are enabled, or in Google Ads Settings.

Your rights

Depending on where you live, you may have the right to access, correct or delete personal data, or to opt out of its sale or sharing. We do not sell personal data. To make a request, email hello@statetaxlab.com.

Children

This site is not directed to children under 13, and we do not knowingly collect their information.
