The short version: We built BillCheck to compare electricity plans from your actual bill without taking retailer commissions. We don't sell your data, our calculators never run advertising trackers, and we never store your name, address, or account number. This page explains exactly what happens to your information.
BillCheck ("we", "us") is a tool that compares South East Queensland electricity plans against your own bill. BillCheck is part of Exactify (exactify.com.au), operated by Mango Private Wealth Pty Ltd (ABN 22 160 640 684). If you have any privacy question or request, contact us through our contact form.
When you upload a photo or PDF of your electricity bill, it is sent securely to our bill-reading service (powered by Anthropic's API) to extract the numbers we need to compare plans — your usage in kWh, the rates and charges, the tariff type, the billing period, and the total.
To make the tool as accurate as possible — especially during beta, while we're learning what real bills look like — we keep a de-identified copy of the detail on each bill that's checked. During beta we deliberately keep the full picture: every charge, credit, discount, concession, rebate, fee, rate, usage figure, tariff and the billing period. Before anything is stored, we remove the details that could identify you:
We use this only to test and improve the accuracy of our extraction and pricing. We do not use it to contact you, and we do not sell or share it. We recommend a solicitor review this policy before the tool leaves beta and starts taking payments.
If you choose to enter your email to be notified about the full/live version, we store that email address for that single purpose — to let you know when it's ready. You can ask us to remove it at any time by emailing us. We won't add you to marketing lists or pass your address to anyone else.
If you leave feedback (a thumbs rating and an optional comment), we store your comment and the headline result you saw so we can improve the tool. Please don't include personal details in the comment box.
You can optionally ask BillCheck to send you a notification when your retailer changes its prices, or a reminder to re-check your bill. This is anonymous and tied to your device only — there's no account and we don't ask for your email. If you turn it on, we store a random identifier for your device, the notification "subscription" your browser provides, and the same de-identified figures from your comparison (your retailer, plan type, postcode and annual cost — never your name, address or account number) so we know which alerts are relevant to you. We use these only to send the alerts you asked for. You can turn alerts off at any time in your browser's site settings, which stops them immediately; the stored subscription becomes inactive and is removed.
On the Rent Assistance calculator page you can ask us to email you when the Rent Assistance rates change. The rates change in March and September, so that is at most twice a year. If you sign up, we store your email address, the topic you chose and the time you said yes (you do that by ticking a box, which is never ticked for you). We store nothing else about you from that form. We use the address only to send you those emails, we don't add you to any other list, and we don't pass it to anyone. Every email has an unsubscribe link, and using it removes your address and the record of your consent. You can also ask us to remove you through our contact form.
On the Family Tax Benefit calculator page you can ask us to email you when the Family Tax Benefit rates change. The rates change on 1 July, and the Rent Assistance rates paid with Family Tax Benefit change in March and September, so that is at most three times a year. If you sign up, we store your email address, the topic you chose and the time you said yes (you do that by ticking a box, which is never ticked for you). We store nothing else about you from that form. We use the address only to send you those emails, we don't add you to any other list, and we don't pass it to anyone. Every email has an unsubscribe link, and using it removes your address and the record of your consent. You can also ask us to remove you through our contact form.
On the Parenting Payment calculator page you can ask us to email you when the Parenting Payment rates change. The rates change in March and September, so that is at most twice a year. If you sign up, we store your email address, the topic you chose and the time you said yes (you do that by ticking a box, which is never ticked for you). We store nothing else about you from that form. We use the address only to send you those emails, we don't add you to any other list, and we don't pass it to anyone. Every email has an unsubscribe link, and using it removes your address and the record of your consent. You can also ask us to remove you through our contact form.
On the paid parental leave calculator page you can ask us to email you when the paid parental leave rate changes. The rate and the income limits change on 1 July, so that is at most once a year. If you sign up, we store your email address, the topic you chose and the time you said yes (you do that by ticking a box, which is never ticked for you). We store nothing else about you from that form. We use the address only to send you those emails, we don't add you to any other list, and we don't pass it to anyone. Every email has an unsubscribe link, and using it removes your address and the record of your consent. You can also ask us to remove you through our contact form.
Our home page and our guide articles use Meta (Facebook) and Google advertising tags to measure our ads, but the calculators never do, here or on anyone else's website. BillCheck does not use advertising cookies or third-party tracking or analytics services. We don't build a profile of you across the web. If you turn on rate alerts, we store a random device identifier on your device (in local storage) purely to link your alerts to this device — it is not used to track you elsewhere.
We also count visits ourselves, without cookies, on every page of this site: which page was opened, where the visit came from (for example Google or Facebook), phone or computer, how long the page was on screen, which links were followed, and whether a calculator or sign-up form was used. We never record what you type, pick or upload, and nothing links one visit to another or to you. These are totals we use to see which pages help people.
These providers may process data on servers outside Australia. We only share what is described on this page, and only for the purposes described.
You can ask us what we hold about you, ask us to correct it, or ask us to delete it — including removing your email from the waitlist. Get in touch through our contact form and we'll action it. We handle personal information in line with the Australian Privacy Principles.
BillCheck is currently in beta and the figures are indicative. Always verify with the retailer before switching. Comparisons are calculated from the data on your bill and publicly filed plan data; we're not paid by any retailer.
If we change how we handle your information, we'll update this page and change the "last updated" date above.
