Last updated 3 October 2026. This describes what the site does today, not what it might do later. If that changes, this page changes first and the date above moves.
This site collects nothing about you. There are no accounts, no cookies, no analytics and no advertising on it at the moment. Nothing you type into a calculator leaves your browser.
When you change a salary, a filing status or a deduction, the arithmetic happens in your browser. The figure is not sent anywhere, not stored anywhere, and nobody here sees it. You can confirm that by turning off your network connection after the page loads: the calculators keep working.
The site sets no cookies. It uses no local storage. It loads no analytics script, no tag manager, no advertising pixel and no social media widget. There is no third party receiving anything about your visit, because there is no third party script on any page.
The typefaces are served from this site rather than from a font service, which is a small thing but it means loading a page does not announce your visit to anyone else.
Pages are served by a hosting provider, and like any web host it processes the technical details a request necessarily contains: the page asked for, the time, an IP address, and the browser's user agent string. That is how any website on the internet works. It is used to serve the page and to keep the service running, and this site does not pull that data into anything of its own, build profiles from it, or combine it with anything else.
Every figure on this site links to the state or federal document it came from. Those are other people's websites with their own privacy practices, and following a link takes you to them. This policy covers this site only.
If you write to the address on the contact page, we have your message and your email address, because that is what an email is. It is used to reply to you and, where you are reporting an error in a figure, to check and fix it. It is not added to a mailing list and not passed to anyone else.
This site is intended to carry advertising, and it does not yet. That matters here because advertising is the thing that would change this page substantially: ad networks generally set cookies or use similar identifiers, and they collect data under their own policies rather than this one.
Nothing of that kind is running today. Before any of it is introduced, this page will be rewritten to say plainly what is being used, what it collects and how to opt out where that is offered. The build refuses to publish a third party script while this page still claims there are none, so the two cannot drift apart quietly.
This is a reference site about tax arithmetic and is not directed at children. It does not knowingly collect anything from anybody, of any age.
Rights to see, correct or delete personal data only bite where there is personal data to act on. This site holds none, so there is nothing to request. If you have emailed us and want that message deleted, say so and it will be.

This page is written to describe the site accurately rather than to cover every eventuality, and it has not been reviewed by a lawyer. If you need a legal opinion about your own obligations, this is not one.
