Overview
This policy explains how this website uses cookies, browser local storage, and similar technologies.
Last updated: 4 April 2026
Strictly Necessary Technologies
The site uses essential technologies required for core functionality and security. These do not require opt-in consent under UK PECR where strictly necessary.
Local Storage
This site uses browser local storage to remember calculator inputs and preferences (for example selected year, selected region, and entered values). This helps preserve your session preferences and reduce repeated entry.
We also store your theme preference (light or dark mode).
Local storage keys currently used:
howmuchtaxdoipay_form_v2— calculator field values and related optionshowmuchtaxdoipay_theme— display theme (light / dark)
Analytics / Marketing Cookies
This website uses Google Analytics (GA4) with measurement ID G-NCWTEPFGJZ to measure site usage and improve content and performance.
Google Analytics can use cookies and similar technologies to distinguish visits and collect interaction/traffic metrics (for example page views, referrer source, and device/browser metadata).
For more information on Google technologies and controls, see policies.google.com/technologies/partner-sites and the Google Analytics Opt-out Browser Add-on.
Third-Party Services
If you click outbound links (including affiliate links), third-party websites may set their own cookies or tracking technologies. Those technologies are controlled by the third party and subject to that party's own privacy/cookie policies.
How to Manage Cookies and Storage
You can remove cookies and local storage through your browser settings. Clearing site data for this domain will reset saved calculator preferences and inputs.

Legal Basis and PECR
Where applicable, use of strictly necessary technologies is based on legitimate interests and PECR exemptions for essential storage/access. Optional non-essential technologies (if introduced) will be based on consent.
Updates
We may update this policy as technologies or legal requirements change. The latest version is always available on this page.
