Service in the country, compatible with different device environments
Effective date and device tracking
Effective: November 2026, this page explains what device-based information is stored, why it is stored, and how to control it
In the BD330 App, device signals are given more priority than name, phone number or transaction-type information, making sign-in, session duration and security checks faster
Many Dhaka users want to open the app with low data, so data collection is limited and unnecessary tracking is disabled
Which device IDs are stored in the BD330 App
Here four types of device signals are used; these are required for account security and login verification
Device ID
Helps identify repeated logins from the same phone
App Session Token
If a session is interrupted, it resumes quickly
Browser fingerprint
Used to detect abnormal behavior in the web version
Network signals
Alerts when the same device logs in from a different network
This data is not used for advertising; only BD330 login verification, preventing unauthorized access, and maintaining a secure session are needed
Fingerprinting and data protection
Fingerprinting relies only on basic signals such as small screen size, OS version, and app version
BD330 APK runs on Android 8+ devices, this verification is smoother; on older phones it is used only for compatibility, not to create a personal profile
Which data is separated
- Device models are kept separate
- Language and time zone are read temporarily
- Only country-level signals are shown for location
- Personal messages are not read
Thus data protection stays strong, and the system does not retain extra data unnecessarily; signing in with Rocket, bKash or Nagad does not create additional data layers
Opt-out controls and login security
There are 3 controls to reduce tracking
Sign out
If you change device, delete the previous session
Disable biometrics
On supported phones, fingerprinting can be disabled
Notification limit
Keep only security alerts and reduce the rest
Password Update
Changing it once every 30 days reduces risk
After BD330 registration, the first task should be to view security settings; this helps detect login anomalies quickly
Third-party SDKs and vendors
Only 3 types of SDKs are kept; each serves a different purpose
Analytics
To understand crashes and load times
Security Layer
To identify bots and suspicious requests
Session support
Maintains continuity on re-login
No SDKs sell your personal content; logging in from Dhaka or Chattogram still adheres to the same minimum standards

How long your BD330 App data will stay may vary by usage, but unnecessary data is not kept; that's the main point
