Privacy Policy

Last updated: July 2026

This is a free expiration date calculator. It needs hardly anything from you, and here is the whole of it.

In a nutshell

The date maths happens in your browser, on your device. The dates you enter stay there and never come to us, no account is needed, and nothing about the visit is kept on our side once you close it.

What the server notes down

Just the routine request line every host records: an IP address, the page and the time, the browser's user-agent, and any page that linked you in. It keeps the site healthy and helps flag abuse, carries no name, and is aged out within roughly a month.

Cookies and visitor counts

Turn cookies off and the calculator behaves the same, since it relies on none. Whatever we set only keeps the page working or holds a small preference, and any visitor count reports a total, not the steps of any one person.

Advertising

There are no third-party ads on the site right now. Were some added later, they might set their own cookies and see your IP, so we would name the providers and link their policies first.

Your rights

You are free to turn down non-essential cookies. Under laws like the GDPR or CCPA you may ask what personal data we hold and request its deletion; we keep no profiles, so usually there is nothing to send, but do get in touch.

Security

Traffic runs over HTTPS and the software is kept current. No website is perfectly secure, yet there is very little of value stored here to begin with.

Children

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

Changes

Any update is posted here with the date refreshed, and a meaningful change is stated openly rather than tucked away.
