Calculator inputs stay in the page
The calculator does not submit your salary, hospital-cover choice or HELP setting to a tax server or AI service. TaxCalcTool does not use those values for advertising or analytics.
Use example values if you are demonstrating the tool on a shared screen. A screenshot or copied result can reveal the information you chose to enter.
Website delivery still involves connection data
Cloudflare hosts and delivers the site. Its network processes connection and request information, which can include your IP address and the page requested, to provide and protect that service. Cloudflare explains its handling of end-user information in its privacy policy.
Running the arithmetic locally does not mean that visiting a website creates no network traffic. The site’s pages and calculation assets still need to reach your browser.
When you contact us
Email sent to [email protected] is forwarded by Cloudflare to the project’s Gmail inbox. Replies from our contact address are sent through Brevo. Your email address and message can be used to investigate and reply to your request.
Use sample figures when reporting a calculation issue. Do not send tax file numbers, tax returns, passwords or bank details. Sending an email is optional and separate from using the calculator.
External links and future changes
Official-source links open websites with their own privacy practices. This release does not include advertising or analytics scripts.
This notice describes the current calculator. Any future feature that collects additional visitor information needs an updated explanation before it is introduced.
