What we collect

• Your email address, to sign you in.
• Home details you enter: street address, suburb, postcode, distributor, battery size and brand, install date. The address makes sure each home has one account holder. If someone tries to register an address that's already taken, we show them a partly hidden version of the account holder's email (for example m•••@g•••.com) so they know to ask that person; we never show the full email.
• The emails of household members (up to four), if the account holder adds them, and the account holder's confirmation that each is 18 or over. We email each a link to sign in, and they can see that home's information. The account holder or the member can end this at any time.
• Your declaration that you're 18 or over, with when you made it. We don't ask for your date of birth.
• If we refund a payment: the refund's amount, date and status, and the reason recorded for it. Card details stay with Stripe; we never see them.
• If you check an Amber bill: your Amber API token is used once, to download that bill's half-hours from Amber, and isn't stored. The Amber data, any meter file you add for the check, and the result aren't stored either.
• If you turn on phone notifications in the Android or iPhone app: the notification address Google or Apple gives the app for that phone, which kinds of notification you chose, and when we last sent each kind. We delete it when you turn notifications off, sign out on that phone, or remove the app.
• Figures from your electricity bills (dates, usage, costs, rates, retailer and plan name). We don't keep the bill file itself.
• Half-hourly meter data you upload, and daily battery totals from FoxESS or Sungrow if you connect them.
• An encrypted access key or token for your battery account, used only to read daily totals.
• Subscription status from our payment provider (Stripe), or from Apple or Google if you subscribe through the App Store or Google Play (through RevenueCat, which handles in-app subscriptions for us). We never see your card number.
• When you accept our terms of use: which version, when, and your browser type, as a record of the agreement.
• Battery alerts and monthly plan-check results we work out from the data above.
• If you ask for a quote through our battery calculator: your name, email, optional phone number, postcode and your calculator results. We only keep these if you tick the consent box.

How we use it

To estimate your battery savings, compare plans and VPP offers, check your battery for faults, email you alerts and a monthly plan check (you can turn these off in Settings), and run the service securely. We don't sell your data.

Installers

If you link your home to an installer, they see how many of their customers use Battery Coach and average savings. They also see how many of their customers have an open battery alert, but not which ones. They never see your bills, meter data or address.

Quote requests

If you ask for a quote through the battery calculator and agree to share your details, we pass your name, contact details, postcode and results to the installer named on the page (or one local installer we choose) so they can contact you. They may use them only to respond to your request. Email hello@solarbatterycoach.com.au to have your request deleted.

Where it's stored

Our database and app run in Sydney, Australia (Supabase and Vercel). When you upload a bill, it's sent to our AI provider (Anthropic, United States) to read the figures, and isn't kept by us afterwards. Payments are processed by Stripe, or by Apple or Google for subscriptions bought in their stores; RevenueCat (United States) keeps the record of those store subscriptions against your account ID, not your name or email. Emails are sent through our email provider ([Resend], United States). Phone notifications go through Google's Firebase Cloud Messaging (Android) and Apple's Push Notification service (iPhone), which may handle them outside Australia, including in the United States. So that they see as little as possible, a notification only says what kind of alert it is (for example “Severe weather forecast near you”): never amounts, plans, your address or battery figures, which you see in the app.

Automated decision-making

We use computer programs to produce savings estimates and plan comparisons for you. These are information only; they don't decide anything about your rights or access to services.

Your choices

You can turn phone notifications on or off, and choose which kinds, in Settings → Phone notifications, or in your phone's settings. You can disconnect your battery, delete meter data or delete a home at any time in Settings. To delete your account, use Settings → Delete my account. To ask about your data, email hello@solarbatterycoach.com.au. You can also contact the OAIC at oaic.gov.au.
