Privacy policy

Last updated 21 September 2026

UnitUtils is designed to need as little data as possible. This policy explains what is and is not collected. If anything here is unclear, write to contact@unitutils.com.

What you enter into the converters

The numbers you type, the units you choose and any search text are processed in your browser. They are not sent to our servers or stored by us, and they are not placed in the web address. We do not ask for your name, email address or any account.

Information stored on your device

To remember your preferences, the site can store small items in your browser's local storage. None of them identify you and none contain the values you convert.

  • Your theme choice (light or dark).

This data stays in your browser. You can remove it at any time by clearing the site's data in your browser settings. See the cookie policy for the full list.

Hosting

The site is hosted on Amazon Web Services (Amazon S3 and CloudFront). To deliver pages, the hosting network necessarily handles technical information about each request, such as your IP address, the page requested and your browser type. We do not use this information to identify individual visitors.

Analytics

UnitUtils does not currently use analytics. If it does in future, it will load only after you have agreed, this policy will be updated first, and it will record only aggregate events such as "a converter was viewed", never the values you entered and never your search text.

Advertising

UnitUtils shows advertising through Google AdSense to fund the site. Google's ad code is loaded on every page, because Google's consent management platform is delivered through it. For visitors in the European Economic Area, the United Kingdom and Switzerland, Google shows a consent message asking whether Google and its partners may store or read information on your device for advertising and personalise ads. You can accept, decline or manage options, and you can change your choice at any time. If you do not consent, Google may show limited or no ads. Google and its partners are responsible for how they use that data; see how Google uses information from sites that use its services and Google's ad settings. Ads never receive the values you enter into a converter.

Third-party services

  • Amazon Web Services: hosting and content delivery.
  • Google AdSense and Google's consent management platform: advertising, and the consent message that controls it.

No other third-party scripts, fonts or trackers are loaded.

Controlling your consent

You can change your choices at any time using the "Privacy and cookie settings" link in the footer. You can also block or delete cookies in your browser settings. The converters work in the same way whichever choice you make.

Your rights

Because we do not collect personal data through the converters, there is usually nothing for us to access, correct or delete. If you are in a region with data protection rights, you can ask us about the data we hold by contacting us. For data held by third parties such as Google, use their own privacy controls.

Children

UnitUtils is a general-purpose utility and is not directed at children. We do not knowingly collect personal information from anyone.

Changes to this policy

If the way the site handles data changes, we will update this page and the date above.
