Privacy policy

Last updated: 7 May 2026

This privacy policy explains how thepercentagecalculator.io handles your data. We have written it in plain English because privacy policies written in legal jargon tend to get ignored, and we would rather you read it.

Who we are

thepercentagecalculator.io is a UK-based website providing free percentage calculators. If you need to get in touch, contact us.

What data we collect and how

Analytics data

We use Google Analytics 4 to understand how people use this site. This helps us see which calculators people find useful, which pages have problems, and how visitors find us in the first place.

Google Analytics works by placing a small piece of code on your device called a cookie. This cookie collects anonymous information: which pages you visited, how long you spent on each page, the general area of the country you are in (not your precise location), and what type of device and browser you are using. It does not collect your name, email address, or any information that identifies you personally.

We only load Google Analytics after you have given your consent. When you first visit the site, a banner gives you the option to accept or decline cookies. If you decline, Google Analytics is not loaded at all and no tracking cookie is placed on your device. If you accept, the cookie is set and analytics will run on future visits.

The calculators themselves

The calculators on this site do not send any data to us or to any third party. Any figures you type into a calculator stay on your own device. Nothing you enter is stored, transmitted, or recorded anywhere.

Advertising

This site may display adverts through a third-party ad network. When advertising is active, advertising cookies may be set if you have consented to them. You can decline advertising cookies via the consent banner on your first visit. This policy will be updated with the specific network's details when advertising is introduced.

Cookies

A cookie is a small text file that a website saves on your device when you visit. On this site, cookies are used only for analytics (if you consent), for advertising (if active and consented), and to remember your cookie preference so we do not show you the consent banner on every visit.

To withdraw your consent or change your cookie preferences, clear your cookies through your browser settings:

  • Chrome: Settings → Privacy and security → Clear browsing data → tick Cookies and other site data
  • Safari: Settings → Safari → Advanced → Website Data → Remove All Website Data
  • Firefox: Settings → Privacy and Security → Cookies and Site Data → Clear Data
  • Edge: Settings → Privacy, search, and services → Clear browsing data

If you clear your cookies, the consent banner will reappear on your next visit and you can make a fresh choice.

Third-party services

We use the following third-party services:

Your rights under UK GDPR

Under UK data protection law, you have the right to:

  • Know what data we hold about you. Because the analytics data collected by Google Analytics is anonymous, we cannot identify you from it. If you believe we hold personal data about you, contact us and we will check.
  • Ask us to delete your data. Because analytics data is anonymous, we cannot identify and delete a specific individual's records. For any other personal data we might hold (for example, if you contacted us by email), we will delete it on request.
  • Restrict data processing. You can decline analytics and advertising cookies at any time by clearing your cookies and choosing to decline when the consent banner reappears.
  • Complain to the regulator. If you are unhappy with how we handle your data, you can contact the Information Commissioner's Office (ICO) at ico.org.uk.

To exercise any of these rights, contact us and we will respond within two working days.

Changes to this policy

If we make significant changes to this policy, we will update the date at the top of this page. We recommend checking back occasionally if you use the site regularly.
