Privacy Policy

Last updated: July 2026

This is a free day and date calculator. It needs barely anything from you, and here is the full picture.

The gist

The date maths runs in your browser, on your device. The dates you pick stay there and never reach us, there is no account, and once you leave nothing about the visit is held on our side.

What the server keeps

Only the ordinary request record a host writes down: an IP address, the page and time, the browser's user-agent, and any referring link. It exists to keep the site running and to flag abuse, holds no name, and is cleared inside roughly a month.

Cookies and counting

Switch cookies off and the calculator still runs, since it depends on none. Whatever we might set only keeps the page working or holds a preference, and any measure of traffic is a total rather than a record of a person.

Ads

The site runs no third-party ads at the moment. If any come later they may drop cookies and read your IP, so we would identify them and link their policies first.

Your rights

You are free to refuse non-essential cookies. Under rules such as the GDPR or CCPA you can ask what personal data we hold and have it removed; there are no profiles here, so usually nothing to return, though you may ask.

Security

The site is served over HTTPS and kept patched. Nothing online is entirely secure, but there is very little of value stored here.

Children

A general-audience tool, this is not aimed at children under 13, and it does not knowingly gather anything from them.

Changes

Any revision goes on this page with the date renewed, and a real change we describe plainly.
