AU Home Loan Calculator is built by Windy Road Technology (windyroad.com.au). The short version: we don't store what you enter.

What happens to the numbers you share

When you use the calculator in ChatGPT, the financial details you provide — income, debts, expenses — are sent to our server, used to work out your estimate, and returned. They are processed in memory and never written to a database. We keep no accounts, no profiles, and no history of your figures.

Your ChatGPT conversation

Your conversation lives with OpenAI under OpenAI's privacy policy. We can't see your chat history — our server only receives the inputs ChatGPT sends for each calculation and, when feedback is recorded, the anonymous categories described below.

What we do count

We keep simple usage counts — landing page views, clicks that open ChatGPT, calculator cards shown, and estimates run — to understand whether the calculator is useful. If you clearly tell ChatGPT that the calculator was helpful or had a problem, it may also record an anonymous feedback category: positive or negative, the reason, and whether it concerned an initial estimate, refinement, or scenario. No comment text, identity, conversation identifier, or financial details are recorded. We don't try to link a website visit, calculation, or feedback event to a particular person or ChatGPT conversation. Raw anonymous usage and feedback events are retained in Google Cloud Logging for 30 days.

Server logs

Our hosting provider (Google Cloud Run) keeps standard infrastructure logs — timestamps, IP addresses, and request status — for a short period, for security and reliability. We don't log the contents of your requests.

This website

This page and the rest of homeloancalc.au set no cookies and run no third-party trackers. The home page sends the two anonymous usage counts described above to our own calculator service.

Where our data comes from

The calculator fetches public interest-rate and inflation figures from official sources. Nothing about you is ever sent to them.
