Privacy Policy

Overview

BillDecoder.au is an independent Australian electricity bill analysis tool. We are committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights.

The short version: your electricity bill is never stored. We collect the minimum data needed to provide the service and nothing more.

Bill analysis

When you upload an electricity bill for analysis:

• Your bill is sent to our AI analysis service (Claude by Anthropic) for processing.
• The bill is processed in memory only and is never saved to any server, database, or file system.
• Once the analysis is complete, the bill data is discarded. We cannot retrieve it.
• The analysis results are displayed in your browser and are not stored on our servers.

Bill data sharing (opt-in)

After receiving your analysis, you may choose to share your bill data with the BillDecoder Index. This is entirely optional.

If you opt in, we store only:

• State (e.g. NSW, VIC)
• Retailer name
• Tariff type, usage rates, daily supply charge
• Total bill amount and estimated annual cost
• Verdict (overcharged, fair, or competitive)
• Usage label (e.g. Evening Peaker)
• Solar feed-in rate (if applicable)

We never store your name, address, postcode, account number, or any text that could identify you personally. Your name, address and account details are stripped out — only pricing data is kept. This data cannot be linked back to you.

This data is used to generate aggregate insights on the BillDecoder Index.

Email notifications (opt-in)

You may choose to provide your email address to receive a one-time notification when better electricity deals are available in your state.

If you opt in, we store:

• Your email address
• Your state
• Your estimated annual cost and tariff type at the time of signup

We will send you at most one email. Every email includes an unsubscribe link. Your email is stored separately from bill pricing data and cannot be cross-linked.

We use Resend to deliver emails.

Data storage and security

All stored data (de-identified bill contributions and email subscriptions) is held in Vercel KV, a managed Redis database hosted by Vercel. Data is encrypted in transit and at rest.

We do not sell, share, or provide your data to any third party, except:

• Anthropic — your bill is sent to Claude AI for analysis (processed in memory, not stored by Anthropic for training).
• Resend — your email address is provided to send the notification email, if you opted in.
• Vercel — hosts the application and database infrastructure.

Cookies and tracking

BillDecoder.au does not use cookies, tracking pixels, analytics services, or advertising. We do not track your browsing behaviour.

Your rights

You have the right to:

• Not participate — bill analysis works without contributing data or providing your email.
• Unsubscribe — every notification email includes a one-click unsubscribe link.
• Request deletion — contact us to have any stored data associated with your email removed.

Under the Australian Privacy Act 1988, you have additional rights regarding the handling of your personal information.

Independence

BillDecoder.au is independent. We do not receive commissions, payments, or incentives from any energy retailer. Retailer recommendations are based solely on AI analysis of your bill.

We may update this privacy policy from time to time. The date at the top of this page indicates when it was last revised.
