Privacy Policy
Last updated: 14 May 2026
1. Who we are
Amperage Pty Ltd operates amperage.app. We help Australian businesses estimate solar savings, analyse electricity bills, and compare system options. This policy explains what data we collect, why, and how we protect it under the Australian Privacy Act 1988 (Cth) and the Australian Privacy Principles (APPs).
2. What we collect
Account details: Name, email address, and company name provided at signup.
Electricity data: Bills you upload (PDF images), consumption CSVs, and project parameters you enter for solar modelling.
Solar Insight leads: Business type, state, postcode, electricity spend, and email address submitted through the free estimate flow.
Server logs: IP address, browser type, and timestamps — standard for any web application.
Payment data: Processed by Stripe. We do not store card numbers or bank details.
3. How we use it
- Run solar sizing, savings, and incentive calculations based on your inputs.
- Extract tariff data from uploaded bills using AI (see section 4).
- Send account emails: verification, password resets, and project notifications.
- Improve accuracy of estimates using aggregated, anonymised consumption patterns.
- Match businesses with solar installers when you opt in.
4. AI bill processing
When you upload an electricity bill, pages are sent as images to Anthropic's Claude API to extract tariff and consumption data. Anthropic does not use API inputs for model training. Bill images are not stored by Anthropic after processing.
We strip identifying information (business name, address, NMI, account numbers) from extracted data before using it to improve estimates for other users. Only consumption shape, tariff structure, and business type are retained.
