Privacy Policy

Last updated: 20 June 2026

This privacy policy explains how Contractor Calculator (contractorcalc.co.uk) handles information when you use our website. We are committed to protecting your privacy. In short: our calculators run entirely in your browser, we have no user accounts or database, and we never ask you for personal information to use our tools.

Information we collect

Contractor Calculator has no backend server that stores your data, no user accounts, and no database of visitors. Specifically:

  • Calculator inputs. The figures you type into our calculators (such as your day rate, salary, or pension contributions) are processed entirely within your browser. They are never transmitted to us. To make the site more convenient, your most recent inputs may be saved to your browser's local storage so they are remembered on your next visit. This data stays on your device and you can clear it at any time by clearing your browser storage.
  • Analytics and advertising data. Like most websites, we use third-party services (Google Analytics and Google AdSense) that collect anonymous usage information through cookies and similar technologies. This is described below.

Cookies and third-party services

We use the following third-party services, which may place and read cookies on your device:

Google Analytics

We use Google Analytics to understand how visitors use the site (for example, which calculators are most popular) so we can improve it. Google Analytics uses cookies to collect anonymous, aggregated information such as the pages you visit and how long you spend on them. We do not use this data to identify individual users.

Google AdSense

We display ads served through Google AdSense to keep this site free to use. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our site and/or other sites on the internet.

You can opt out of personalised advertising by visiting Google Ads Settings. You can also learn more about how Google uses information from sites or apps that use its services at How Google uses data when you use our partners' sites or apps.

For more detail on the cookies used on this site and how to disable them, see our Cookie Policy.

Affiliate links

Some links on this site are affiliate links to third-party accounting software providers, including FreeAgent, Xero, and QuickBooks. If you sign up through one of these links, we may earn a commission at no additional cost to you. These providers operate their own privacy policies, which govern any information you provide to them once you leave our site.

Managing cookies

You can control and delete cookies through your browser settings. Most browsers let you refuse cookies or alert you when a site tries to set one. Blocking advertising and analytics cookies will not affect your ability to use our calculators, as they run independently of these services.

Children's privacy

This site is intended for UK contractors, freelancers, and sole traders, and is not directed at children. We do not knowingly collect information from children under the age of 13.

Changes to this policy

We may update this privacy policy from time to time. Any changes will be posted on this page with an updated revision date.
