Policy start and how to read
This privacy policy takes effect July 2026; on the 4777b App biometric login, cookies and user rights are all in one place.
In Bangladesh, running the app on Android phones, people often want answers, so language is kept simple for Dhaka, bKash, Nagad and Rocket users.
Local use
Opening an account with bKash or Nagad, privacy rules stay the same; only device and permission settings may differ.
Quick check
No data is blocked; what stays on device and what goes to server matters.
4777b App biometric data required
Sometimes fingerprint, sometimes phone face unlock are used; these are only to log in quickly on your device.
If you want to open on a Dhaka bus, biometric login works; with permission on 4777b Login screen, authentication stays on the phone.
What signal is shown
The app generally does not read facial data or raw fingerprint data; only reads authentication outcomes and permission status.
This follows the same Android security flow, so sign-in is smoother in the 4777b App.
Data stays on the phone
Biometric templates stay in your device's secure storage; full biometric data is not sent to the server.
Thus, even with 99.4% uptime, privacy does not drop; after downloading 4777b using bKash, local storage remains the primary trust level.
Why it's good
Even if you lose the phone, biometric unlock cannot be copied to another device; same limit applies for Nagad or Rocket-linked accounts.
Without your permission, the previous biometric profile cannot be moved.
Why not upload to server?
To protect privacy, the 4777b App does not upload raw biometric data; only authentication results and small security logs may be kept.
This keeps login fast on Dhaka's busy networks with 374K+ users, while personal identity remains separate.
How to disable biometric login
If you want, you can turn off fingerprint or face unlock in settings; password and 4777b Login remain available.
On the same phone, another family member using the app stops biometric access by removing app permission in Android settings.
Three small steps
১. Open app settings
২. Find security or privacy section
৩. Turn off biometric toggle
