ChangeBro

Privacy Policy

Last updated: August 1, 2026

Scope

This policy explains how information is handled when you use the ChangeBro app for iPhone (including its Home Screen widget) and our website. In data-protection terms, the developer of ChangeBro is the controller of the information described here. Contact details are in the final section.

Information stored on your device

What you create

Your home name, chores (names, icons, notes, schedules, and reminder settings), supplies (names, notes, stock levels, and purchase links), your completion and restock history with timestamps, and your display name, avatar emoji, and avatar color.

App preferences

Settings such as language, appearance, and setup state, stored in the app's own preferences on the device.

Widget data

A small snapshot of upcoming chores is written to a shared app-group container on the device so the Home Screen widget can display it without launching the app. This snapshot never leaves the device.

All of the above stays on your iPhone (and in your own iPhone backups, if you use them) unless you turn on household sharing.

The anonymous account and optional household sharing

The anonymous account (created only for household sharing)

ChangeBro uses Supabase as its sync provider. When you start creating, previewing, or joining a shared home, the app signs in anonymously and stores the resulting session in the iOS Keychain. No email address, phone number, or password is involved: the account is a random identifier, created without any information about you. Local-only use does not contact Supabase or create an account. Supabase records the account row and the technical details any web request carries — IP address, time, and app version. Your chores, supplies, notes, and history are not uploaded until you create or join a shared home.

Optional household sharing

When you create or join a shared home, the anonymous account becomes the owner or member of the home, and household content starts being synchronized. What is sent to the server:

  • The home's name and its private invitation code (a random 256-bit token).
  • Your membership record: display name, avatar emoji, avatar color, role (owner or member), join date, and your anonymous account identifier.
  • A snapshot of the shared home's content: chores with their names, notes, schedules, and reminder settings; supplies with their names, notes, stock levels, and purchase links; and completion history, including timestamps and which member performed each action.

The snapshot is synchronized when you bring the app to the foreground, shortly after you make a change, and when another member's change arrives. A realtime channel is used only to signal that a new version of the snapshot is available. You can leave a shared home at any time, and the app then offers to keep a private local copy or clear it from the device.

Household visibility: everyone in a shared home can see that home's chores, supplies, notes, history, member profiles, and who completed each action. The invitation code is a secret — treat it like a password. An owner can create a new code (which immediately invalidates the old one) and remove members.

Sending an invitation: the app shares or copies the invitation as text containing the code. If you pass it on with the iOS share sheet, it travels through whichever app you choose — Messages, Mail, or a third-party messenger — and that transmission is governed by that app's own privacy policy, not ours.

What ChangeBro does not collect

  • No real name, email address, phone number, or password.
  • No contacts, calendars, photo library, health data, or location data.
  • No advertising identifier, and no ad networks of any kind.
  • No third-party analytics, attribution, or crash-reporting SDKs.
  • No payment or purchase information.

We do not sell or share personal information for advertising, and we do not use your content to train machine-learning models.

Camera and QR codes

The camera is used for one purpose: scanning a household invitation QR code. Scanning is performed live on your device, and no photo or video is recorded, stored, or transmitted. You can decline or revoke camera access in iOS Settings — the invitation code can always be typed or pasted instead.

Notifications

Chore reminders are local iOS notifications scheduled on your device. ChangeBro does not operate a push-notification server and does not collect device push tokens; reminder text is generated on the device. A reminder shows the chore's name, so it can appear on your Lock Screen — iOS Settings let you hide notification previews if you would rather it did not. You can change notification permission in iOS Settings and adjust reminder timing per chore in the app.

How information is used, and the legal bases

  • To provide the app's core features — schedules, reminders, history, and supply tracking (performance of our agreement with you).
  • To create and maintain the anonymous account when you use household sharing (performance of our agreement with you).
  • To synchronize a shared home between members and show who completed each action (performance of our agreement with you).
  • To protect invitation codes and control access to shared homes (our legitimate interest in preventing abuse).
  • To maintain reliability, diagnose faults, and keep the service secure (our legitimate interest in a functioning service).
  • Camera access and notifications operate on your consent, which you can withdraw at any time in iOS Settings.

Who can access information

Members of a shared home, as described above. Beyond them, information is processed by our service providers on our instructions: Supabase, which hosts the database, anonymous authentication, and realtime service for household sharing, and our website hosting provider. We may disclose information if we are legally required to do so, and would limit any such disclosure to what is required.

International transfers

Servers used for household sharing and for our website may be located outside your country, including in the United States. Where required by law, such transfers rely on appropriate safeguards, such as the European Commission's standard contractual clauses.

Retention and deletion

Data on your device is kept until you delete it. You can delete individual chores, supplies, or history entries; use "Erase all data" under Settings > About to wipe the app's content and scheduled reminders; or delete the app.

"Erase all data" is a device reset. If you are in a shared home, this device first leaves or detaches from the household, then erases its local copy; the other members keep the server copy. This action does not delete your anonymous account.

Content in a shared home remains on the server for as long as the home exists, so that other members keep working access. Leaving a household deletes your membership record and ends your access. Using "Delete account" under Settings > About permanently deletes the anonymous account. If you own a household with other members, you must choose one of them as the new owner; if you are its only member, the server household is deleted. Otherwise your profile and account identifier are removed from the household snapshot, and past actions remain only as unattributed history.

Deleting the app removes everything stored on the device. It does not delete a shared home or your anonymous account from the server. Use the in-app "Delete account" option before uninstalling, or contact us using the address below; we will act within 30 days. Residual copies may persist in encrypted backups for a short period before being overwritten.

Your rights

Depending on where you live, you may have the right to access, correct, delete, export, or restrict the processing of your personal information, and to object to processing based on legitimate interests. Because household accounts are anonymous, we may need details such as your home's invitation code or identifier in order to locate the right data — without them we may be unable to identify you, and will say so rather than act on the wrong data.

If you are in the EEA or the UK, you also have the right to lodge a complaint with your local data protection authority.

Security

Data in transit is protected with TLS. On the server, PostgreSQL row-level security restricts each home's rows to the members of that home. Your anonymous session token is stored in the iOS Keychain, and invitation codes use 256-bit random tokens that an owner can rotate at any time. No system can be guaranteed perfectly secure, and we do not claim otherwise.

Children

ChangeBro is a general household utility and is not directed to children under 13 (or under 16 where local law sets that age). We do not knowingly collect personal information from them. A parent or guardian who believes a child has provided information through household sharing can contact us to have it removed.

Our website

Our website has no advertising, no tracking cookies, no accounts, and no marketing forms. Our hosting provider processes standard request information — such as IP address, browser type, and request time — to deliver and secure the site.

Changes to this policy

We may update this policy as the app develops. The date at the top of the page changes when we do, and material changes will be highlighted in the app or on our website.
