Privacy policy
Effective date: 4 November 2026
This policy explains what information QuickMaths (quickmaths.com.au) collects, how it's used, and the choices you have. We follow the Australian Privacy Principles in the Privacy Act 1988 (Cth).
What you type into the calculators
Every calculation runs locally in your browser. The salaries, prices, dates and other numbers you enter are not sent to us, not stored on any server, and not shared with anyone. Close the tab and they're gone. The only thing we save on your device is your light or dark mode choice, kept in your browser's local storage.
Advertising
We may show ads from Google AdSense to keep the site free. In that case:
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the internet.
- You can opt out of personalised advertising by visiting Google's Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalised advertising at www.aboutads.info.
- If you opt out, you'll still see ads, but they won't be based on your browsing.
Learn more about how Google uses information from sites that use its services.
Analytics
We may use analytics tools, such as Google Analytics or Google Search Console, to understand how many people visit and which pages are useful. These tools may set cookies and collect things like your browser type, device, approximate location (city or region), the pages you view and how you arrived. This data is aggregated, and we don't use it to identify you.
Cookies and your choices
You can block or delete cookies in your browser settings. The calculators will still work without them.
If you email us, we'll use your address and message only to reply. We don't add you to a mailing list or share your email.
Children
This site is meant for a general audience, and we don't knowingly collect personal information from children.
Links to other sites
Some pages link to the ATO and other sites. Their privacy practices are their own.
Changes
If this policy changes, we'll update this page and its effective date.

For privacy questions, to ask what we hold about you, or to make a complaint, email ather.ghazi@gmail.com. If you're not happy with our response, you can contact the Office of the Australian Information Commissioner.
