Your privacy matters, and the short version is simple: this calculator does its work in your own browser and does not collect the income figures you type. This page explains that in full.
The information you enter
Any income, deduction or age details you enter into the calculator are processed entirely on your device. These figures are not transmitted to us, not stored on any server, and not shared with anyone. Close or refresh the page and they're gone.
Analytics and cookies
We may use privacy-respecting analytics to understand which pages are useful — for example, how many people visited a guide. Where analytics or advertising cookies are used, they collect aggregate, non-identifying information such as page views and general location. You can control or block cookies through your browser settings at any time.
Advertising
This site may display ads from third-party networks to keep the tool free. These networks may use cookies to show relevant ads. We don't share your calculator inputs with them — those never leave your browser in the first place.
Third-party links
Our pages sometimes link to official or reference sites. Once you follow such a link, their privacy practices apply, not ours. We'd encourage you to read the privacy policy of any site you visit.
Children's privacy
This site is intended for adult taxpayers and is not directed at children under 13. We do not knowingly collect information from children.
Changes to this policy
If our practices change, we'll update this page and the date below. Continued use of the site means you accept the current version.
