Privacy policy
Draft for review. This policy is not yet in force.
Last updated 23 October 2026
Bagatelle Home is run by Bagatelle Energy Pty Ltd (ABN 17 697 322 848). In this policy, "we" and "us" mean Bagatelle Home.
Bagatelle Home helps you understand solar, batteries and your home's energy, and build an Energy Blueprint you can take to retailers. This policy explains what information we hold about you, why, where it is kept, who can see it, and the choices you have.
What we collect
- Your account: your email address and password. Your password is handled by our sign-in service; we never see it.
- Your details, if you give them: your name, surname, phone number and address. All are optional.
- Your home and your goals: your answers about your home, how you use energy, your appliances and what you want your system to do. These build your Energy Blueprint.
- Your documents and photos: electricity bills, photos of your site and switchboard, quotes and responses from retailers that you upload.
- Your conversations with Sunny, and a record of what you have learned, so Sunny can build on it.
- Your choices: your privacy choices and the exact wording you saw when you made them, and your answers when you close your account.
- Technical records: the services that run Bagatelle Home keep their own records, which can include your email address and the internet address you connected from.
We collect this from you, when you use Bagatelle Home. We do not buy information about you.
Why we use it
- To run your account and show you your own information.
- To build and keep your Energy Blueprint.
- To answer your questions and read the documents and photos you ask us to read.
- To improve Bagatelle Home, using only information that does not identify you (see "What we keep").
- To share your Blueprint with the Energy Partners you choose (see "Retailers and Energy Partners").
We do not sell your information, and we do not use it for advertising.
Where it is kept and who can see it
Your information and the files you upload are stored in Australia, in Sydney, and encrypted when stored. Each record is locked to your account, so other people using Bagatelle Home cannot see it. Bagatelle Energy administration staff can see records when needed to run and fix the service.
When AI is used
We use AI only where it is needed, and we send it as little as we can.
- Works without AI: your forms and measurements, your Blueprint, and reading your electricity bills.
- Uses AI, only when you ask: answering your questions to Sunny, and reading a photo or document. We ask you before sending any photo or document, every time.
- Each question to Sunny sends your question, a little of your recent chat and your Blueprint answers. In your privacy settings you choose what else goes: nothing that identifies you, your area but not you, or everything including your name and address.
- What you type goes as you typed it. If you write your address, it goes.
- Before a quote or a retailer's response is read, we remove your name, contact details and street address wherever they appear as you gave them to us. We keep your postcode. Anything written differently, or a page sent as a picture, may still show your details.
Labels in the app show whether each part uses AI: "No AI", "AI, asks first", or "AI".
Information sent outside Australia
The AI services Bagatelle Home uses are run by companies outside Australia, so anything sent to them is processed overseas. These companies are based in the United States.
The services that run Bagatelle Home, including hosting and the AI service, keep their own records for a time under their own rules.
Retailers and Energy Partners
Nothing goes to a retailer or Energy Partner until you confirm your Blueprint, and you choose which Energy Partners receive it. They see your Blueprint, its photos and your address, so they can lay out panels on your roof and quote. Your name, phone number and email address are not shared until you sign an agreement with one of them. If you sign with one Energy Partner, the others can no longer see your information.
You can also download your Blueprint and give it to any retailer yourself. What that retailer does with it is up to them.
What we keep
- General questions, such as "what does a hybrid inverter do?", are kept with Sunny's answer, without anything that identifies you, so we can review and improve answers for everyone. They can't be traced back to you, so they stay if you close your account. Answers about you or your home are not kept. You can opt out in your privacy settings.
- Bill lines: if we cannot read some figures on your bill, we keep only the lines that hold them, with long numbers hidden and your name, address, phone and email removed, so we can improve how bills are read. Only the Bagatelle Home team sees them, and they are deleted if you close your account.
Cookies and your browser
We use a cookie to keep you signed in. Your browser also keeps a few display preferences, such as how much detail you like in lessons. We do not use analytics, advertising or tracking cookies.
Seeing, changing and deleting your information
- You can see and change your details, answers and documents in Bagatelle Home at any time.
- You can change your privacy choices at any time in your privacy settings.
- You can close your account and come back to it later, or have your data deleted now. If you close it, we keep your Energy Blueprint for 12 months, and signing in opens it again as you left it. If you delete, your data is deleted straight away, and this cannot be undone.
- We ask whether we may keep an anonymised copy to improve Bagatelle Home. If you say no, all of your data is deleted.
To ask for a copy of your information, or for help with any of this, contact us.
