Privacy

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

What this site stores

Nothing in your browser on purpose. Pages do not use cookies or other browser storage. 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 the form service 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.

The calendar file

A calendar file is built in memory and downloaded only if you ask. It lists the April 15, 2027 due date and the expected October 15, 2027 filing-extension date. It does not include the amounts you typed. Closing the page drops it. It is not uploaded.

Other sites

Guides link to public IRS pages. Those sites have their own policies. This site is not the IRS.
