Privacy policy

Last updated 26 September 2026.

The short version

Everything you type into our calculators stays in your browser. The numbers you enter are never sent to our servers, stored, or shared — close the tab and they’re gone.

What we collect

We don’t offer accounts and we don’t ask for your name or email. Our hosting provider (Vercel) keeps standard server logs (IP address, browser type, pages requested) for security and performance; these are retained briefly and not used to identify you.

Analytics

We use Vercel Web Analytics to understand which calculators people find useful. It records aggregate page views, referrers, country and device type. It sets no cookies, does not track you across other sites, and does not build profiles of individual visitors; the identifier it uses to count visits is a temporary hash that is discarded within 24 hours.

Advertising and affiliate links

We don’t currently show ads. If we add advertising in future we’ll update this policy first. Some links on this site are affiliate links, which means we may earn a commission if you sign up to a product through them — at no extra cost to you. Affiliate relationships never change the numbers our calculators produce.

Your rights

We handle personal information in line with the Australian Privacy Principles under the Privacy Act 1988 (Cth). Since we don’t store personal data there is usually nothing to access or correct, but if you have any privacy question or concern, contact us at the email below and we’ll respond promptly.
