Privacy

These pages are static. Reading them does not create an account and does not send what you type in the checker.

What this site stores

Nothing in your browser on purpose. Pages do not use cookies, local storage, session storage, or IndexedDB. There is no analytics service and no advertising network.

The contact form

If you press Send, the name, email, and message you typed are posted to Web3Forms at api.web3forms.com so the note can be delivered. That is the only request this site makes to another server, and it happens only then. The checker does not use that request. No email address is published on these pages.

Files you download

A calendar file is built in memory and downloaded only if you ask. Closing the page drops it. It is not uploaded.

Other sites

Guides link to public sources, including irs.gov and the electronic Code of Federal Regulations. Those sites have their own policies. The tools page does not link out.
