Privacy policy

Last updated: May 2026

Overview

This privacy policy explains how howmuchpay.co.uk ("we", "us", "our") handles information when you use this website. We are committed to protecting your privacy.

The short version: the salary figures you enter into the calculator are never sent anywhere. All calculations happen entirely within your browser. We do not store, collect or transmit any salary data.

Information we do not collect

We do not collect, store or process:

  • Salary or income figures entered into the calculator
  • Tax calculation results
  • Names, email addresses or contact details (there is no registration or account system)
  • Payment information of any kind

Cookies and analytics

This website uses cookies set by third-party services for the purposes described below. You can manage cookie preferences through your browser settings. Blocking these cookies will not affect the calculators — they work entirely without cookies.

Google AdSense

We use Google AdSense to display advertisements on this site. Google AdSense uses cookies to serve relevant ads based on your visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your prior visits to this website or other websites.

You may opt out of personalised advertising by visiting Google Ad Settings. Alternatively, you can opt out of third-party vendor use of cookies for personalised advertising by visiting aboutads.info.

PostHog analytics

We use PostHog to understand how visitors use this website — for example which calculators are most popular and how people navigate between pages. This helps us improve the site.

PostHog collects anonymous usage data including pages viewed, browser type, device type, and country (derived from IP address). Your IP address is not stored in full. We do not track individual users across sessions unless they explicitly identify themselves (there is no account system on this site, so this does not apply).

PostHog data is processed in the EU (Frankfurt, Germany). For more information, see PostHog's privacy policy.

To opt out of PostHog tracking, you can enable your browser's "Do Not Track" setting or use a content blocker. PostHog respects the Do Not Track header.

Third-party links

This site may contain links to external websites, including links to GOV.UK and HMRC guidance pages. We are not responsible for the privacy practices or content of those sites. We encourage you to read the privacy policies of any external sites you visit.

Changes to this policy

We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated date at the top. Continued use of the site after any changes constitutes acceptance of the updated policy.
