Privacy policy

Last updated 16 October 2026.

This policy explains what information OzCalcs ("we") collects when you use ozcalcs.com, and how it's used.

Calculator inputs

Our calculators run entirely in your web browser. The numbers you enter are not sent to us or stored on our servers. If you copy a link to a result, the values appear in that link so it can reopen the same calculation.

Information collected automatically

Like most websites, our hosting provider (Cloudflare) processes basic technical information such as your IP address, browser type and the pages you visit, to deliver the site securely and to produce anonymous visitor statistics. We don't use this information to identify you.

Cookies and local storage

We store your light or dark theme choice in your browser's local storage. We don't set other cookies ourselves.

Advertising

We use Google AdSense to show ads, which keeps the site free. Third-party vendors, including Google, use cookies to serve ads based on your previous visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to our site and other sites on the internet.

You can opt out of personalised advertising by visiting Google Ads Settings, or opt out of some third-party vendors' cookies at aboutads.info. You can learn more about how Google uses information from sites that use its services.

Links to other websites

We link to government and other external sites. We're not responsible for their content or privacy practices.

Your rights

We handle personal information in line with the Australian Privacy Principles. If you email us, we use your email address only to reply. To ask about or correct information we hold, email hello@ozcalcs.com.
