CartMama stores your business data — products, sales, purchases, customers, suppliers, and ledgers — entirely on your phone's local storage. We never see, receive, or have access to this data.
The only information that may leave your device is described below:
| Data | When it's used | Where it's stored |
|---|---|---|
| Phone number | Only when you choose to unlock Pro features | Our activation server |
| Device identifier | Only when you choose to unlock Pro features | Our activation server |
| Business data (sales, stock, customers, ledgers, etc.) | Never transmitted | Stays on your device only |
If you choose to upgrade to CartMama Pro, you send a payment via bKash or Nagad and enter your phone number in the app. We use your phone number and a unique device identifier solely to:
If you never tap "Upgrade to Pro," none of this is collected — CartMama works fully offline and no data ever leaves your phone.
CartMama's backup feature saves a copy of your local database directly to your phone's storage (Downloads folder). This backup file never passes through our servers — it stays on your device, and sharing it (for example, via WhatsApp to yourself) is entirely your choice and under your control.
| Permission | Why |
|---|---|
| Camera | To scan product barcodes and QR codes (Pro feature) |
| Storage | To save backup files and generated invoice images on your device |
| Notifications | To alert you about low stock or overdue customer payments |
| Internet | Used only during Pro activation; the app otherwise works fully offline |
Since your business data lives only on your device, deleting the app removes it completely — we don't retain a copy. If you'd like your phone number removed from our activation records, contact us using the details below and we'll delete it.
CartMama is a business tool intended for shop owners and is not directed at children. We do not knowingly collect information from anyone under 13.
If this policy changes, we'll update the date at the top of this page. Continued use of CartMama after a change means you accept the updated policy.
