We don't collect anything.

The short version

We do not collect, store, transmit, sell, or share personal information. The calculators are plain HTML and JavaScript. The figures you type into a calculator stay in your browser's memory, are never sent to a server, and are gone when you close the tab.

What we do not use

• No cookies — no analytics cookies, advertising cookies, session cookies, or preference cookies.
• No third-party scripts — no analytics, no ad networks, no tag managers, no social widgets, no fonts loaded from a third party.
• No accounts — there is no registration, no login, no profile, and no email list.
• No forms — this site has no contact form and does not accept or store messages.
• No payments — there is nothing to buy here.

What a hosting provider may still log

This site is served as static files by a hosting provider. Like virtually every web server, that provider may record standard access logs for the request itself — typically the IP address, browser user agent, requested page and timestamp — in order to deliver the files and keep the service secure. We do not control those logs, do not receive them for profiling, and do not combine them with anything else. This is server infrastructure, not tracking that we operate.

Links to other sites

Our pages link to the IRS, state tax agencies, and published data sources for reference. Once you leave this site, those organizations' own privacy policies apply. We are not responsible for their practices.

Advertising in the future

There is no advertising on this site today. If we add an advertising program later to cover hosting costs, that provider may use cookies or similar technologies, and we will update this policy before any such script is added. We will never place ads inside the calculator or in a way that shifts the page around while you are using it.

Children

This site is not directed at children under 13, and we do not knowingly collect information from anyone. Because we collect no information at all, there is nothing to delete on request.

Changes

If this policy changes, we will replace this page and update the date above. There is no account to notify and no mailing list.
