Privacy Policy
Last updated 18 October 2026
Cozii helps households and roommates organise groceries, spending, schedules, tasks and household staff. This policy explains what we collect, why, who can see it and the choices you have.
What we collect
- Account details: your name, email address and a securely hashed password (we never store or see your actual password).
- Household content you or your household add: inventory items, prices, receipts and photos, expenses and budgets, shopping requests, tasks and photo proof of work, notes, handbook and rules, documents and links, schedules and reminders, messages and voice notes.
- Information about other people that a household adds, for example family members (which can include children), their birthdays, school, allergies or medical notes, and household staff, including phone numbers, ID numbers, salary, attendance and payroll. Only add this if you have the right to share it, and tell the people involved.
- Device information: a push-notification token so we can send the notifications you turn on.
- Technical logs: basic server logs (such as time, request and error details) kept briefly to keep Cozii secure and working.
We do not use advertising, sell your data, or track you across other companies' apps or websites.
How we use it
- To provide Cozii's features to you and the members of your household.
- To send emails you ask for, such as sign-up confirmation and password reset codes.
- To send the notifications you choose (you can switch each type on or off in the app).
- To keep the service secure, fix problems and answer support requests.
AI receipt reading
If you choose to scan a receipt, the photo is sent to OpenAI to read the items and prices. Cozii asks for your permission the first time. Photos are used only to read that receipt and are not used to train OpenAI's models. You can always add items by hand instead.
Who can see your data
Content in a household space is visible to its members according to the permissions the owner sets (for example, which staff can see which items, or who is a house manager). Messages between staff and the household are visible to that staff member, the owner and house managers. Cozii personnel can access data only when needed to operate, secure or support the service, and never see your password.
Service providers
We use trusted providers to run Cozii: cloud hosting (Render), database hosting (MongoDB Atlas), email delivery (Resend), push notifications (Expo and Apple), and AI receipt reading (OpenAI, only when you scan). They process data on our behalf and only to provide their service. Data may be stored or processed outside your country, including in the United States, and is transmitted over encrypted (HTTPS) connections.
How long we keep it
We keep your data while your account or household is active. When you delete your account it is permanently removed, and spaces that only you belong to are deleted with all of their data. Backups are overwritten within about 30 days.
Your choices and rights
- Access and correct: you can view and edit your information in the app.
- Delete: Profile → Delete account (staff: at the bottom of the home screen) removes your account.
- Other requests: to get a copy of your data, or for any privacy question, email coziisandbox@gmail.com. We reply within 30 days.
Depending on where you live (for example Indonesia's Personal Data Protection Law, Canada's PIPEDA, or the EU/UK GDPR), you may have further rights, such as objecting to processing or complaining to a data protection authority.
Children
Cozii accounts are for people aged 13 and over. Parents or guardians may add information about their children (such as schedules or allergies) to help run the household; that information is controlled by the household and can be edited or deleted at any time.
Changes
If we make important changes we will update this page and the date above, and tell you in the app when appropriate.
