This page explains what information The Useful Site does and doesn't collect, and how cookies and advertising work here.
Effective date: November 4, 2026
The Useful Site (theusefulsite.com) is a collection of free online tools — calculators, converters and a QR code generator. The tools run entirely in your web browser, on your own device.
The tools themselves collect nothing. Everything you type into a calculator or converter — a home price, a weight, a link for a QR code — stays in your browser. It is never sent to us, never stored, and is gone when you close the page. There are no accounts, no sign-ups and no forms that send us your details.
Like almost every website, our hosting and content delivery providers automatically record standard server log data when you visit: your IP address, browser type, the pages you visited and the date and time of your visit. This data is used to keep the site running, understand which tools people use, and protect the site from abuse. It is not used to identify you personally.
We may use cookies — small text files stored in your browser — to operate the site and understand how it is used.
Third-party advertising partners, including Google, also use cookies to serve ads. Specifically:
Third-party advertisers and ad networks may use cookies, JavaScript, or web beacons in the ads shown on this site, and they receive your IP address as part of serving those ads. We have no access to or control over the cookies used by third-party advertisers; their own privacy policies govern how they use that information. You can consult the privacy policy of Google and any other advertiser for more detail.
The figures shown by our tools — such as currency exchange rates and gas prices — come from public sources and are provided for general information only. They are not financial advice, and we do not guarantee they are current or complete at the moment you view them.
This site is not directed at children under the age of 13, and we do not knowingly collect personal information from children under 13.
If we change this policy, the updated version will be posted on this page, with a new effective date at the top.
