Privacy Policy
AusTax Tools is committed to your privacy. All tax calculations run entirely in your browser – the numbers you enter never leave your device.
Data we collect
This is a static website. All calculations run entirely in your browser using JavaScript. We do not have a backend server, database, or any way to receive, store, or process the data you enter into our calculators.
If you use Save this estimate on a calculator, or a planner that remembers your answers, those inputs are kept in your browser's local storage on your device only. They are never sent to us. You can view and delete saved estimates on My saved estimates, or remove everything by clearing this site's data in your browser.
Analytics
We use Google Analytics 4 to understand how visitors use our website. This helps us improve our calculators and content. Google Analytics collects:
- Pages you visit and time spent on each page
- Your approximate location (country/city level)
- Device type, browser, and operating system
- How you found our website (search engine, direct link, etc.)
Google Analytics does not collect the numbers you enter into our calculators – those never leave your browser.
Google Analytics uses cookies to distinguish unique visitors. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.
For more information, see Google's Privacy Policy.
Advertising
This site is funded by advertising. We work with Mediavine, an advertising partner that serves and measures the ads on our pages. Mediavine and its advertising partners may use cookies, device identifiers and similar technologies to deliver ads, limit how often you see the same ad, and measure whether an ad was seen.
Those partners may process your IP address, browser and device type, approximate location and your interactions with ads, each under its own privacy policy. Mediavine's policy is at mediavine.com/privacy-policy, and the current list of partners is available from its consent banner where that banner is shown.
Where Mediavine shows its consent banner — in regions covered by the GDPR, UK GDPR, or similar consent laws — it asks you to accept or reject personalised advertising before an advertising cookie is set, and you can change that choice at any time from the privacy link in the banner. You can also opt out of third-party vendor cookies more broadly at youradchoices.com.
Mediavine Programmatic Advertising (Ver 1.1)
The Website works with Mediavine to manage third-party interest-based advertising appearing on the Website. Mediavine serves content and advertisements when you visit the Website, which may use first and third-party cookies. A cookie is a small text file which is sent to your computer or mobile device (referred to in this policy as a “device”) by the web server so that a website can remember some information about your browsing activity on the Website.
First party cookies are created by the website that you are visiting. A third-party cookie is frequently used in behavioral advertising and analytics and is created by a domain other than the website you are visiting. Third-party cookies, tags, pixels, beacons and other similar technologies (collectively, “Tags”) may be placed on the Website to monitor interaction with advertising content and to target and optimize advertising. Each internet browser has functionality so that you can block both first and third-party cookies and clear your browser’s cache. The "help" feature of the menu bar on most browsers will tell you how to stop accepting new cookies, how to receive notification of new cookies, how to disable existing cookies and how to clear your browser’s cache. For more information about cookies and how to disable them, you can consult the information at All About Cookies.
Without cookies you may not be able to take full advantage of the Website content and features. Please note that rejecting cookies does not mean that you will no longer see ads when you visit our Site. In the event you opt-out, you will still see non-personalized advertisements on the Website.
The Website collects the following data using a cookie when serving personalized ads:
- IP Address
- Operating System type
- Operating System version
- Device Type
- Language of the website
- Web browser type
- Email (in hashed form)
Mediavine Partners (companies listed below with whom Mediavine shares data) may also use this data to link to other end user information the partner has independently collected to deliver targeted advertisements. Mediavine Partners may also separately collect data about end users from other sources, such as advertising IDs or pixels, and link that data to data collected from Mediavine publishers in order to provide interest-based advertising across your online experience, including devices, browsers and apps. This data includes usage data, cookie information, device information, information about interactions between users and advertisements and websites, geolocation data, traffic data, and information about a visitor’s referral source to a particular website. Mediavine Partners may also create unique IDs to create audience segments, which are used to provide targeted advertising.
If you would like more information about this practice and to know your choices to opt-in or opt-out of this data collection, please visit National Advertising Initiative opt out page. You may also visit Digital Advertising Alliance website and Network Advertising Initiative website to learn more information about interest-based advertising. You may download the AppChoices app at Digital Advertising Alliance’s AppChoices app to opt out in connection with mobile apps, or use the platform controls on your mobile device to opt out.

Cookies
We use cookies for Google Analytics and for Mediavine advertising. Analytics cookies help us understand website traffic and usage patterns. Advertising cookies are used by Mediavine and its partners to serve ads and measure their effectiveness. You can manage your cookie preferences through your browser settings.
Hosting
This website is hosted on Cloudflare Pages. Cloudflare may collect standard server logs (IP addresses, request times) as part of their infrastructure. We do not have access to this data. See Cloudflare's Privacy Policy for details.
Error diagnostics
If a page's JavaScript fails, a technical error report (the error message, the page URL, browser and OS version) is sent to Sentry so we can fix it. It carries no calculator inputs, sets no cookies, and we do not ask Sentry to store your IP address. See Sentry's Privacy Policy for details.
Changes to this policy
If we ever change our practices, we will update this page.
