ban21 Privacy Policy: ban21 App, data protection, cookies
This page explains ban21 privacy policy in a very simple way; the rules are updated as of November 2026, and you will see the same information when logging in from Dhaka.
How your account, ban21 Login, and ban21 Register information is kept is clearly stated here; using the ban21 App may cause some information to come automatically, but its purpose is always clear.
What information we collect
1: Basic account information
Name, phone number, and login information are required when registering ban21 to operate the account.
2: Device and app data
Device type, version, and language settings are included when opening the ban21 APK or ban21 App, making the app run quickly and stably.
3: Usage information
You viewed which page, how long you stayed, and which features you opened; these are in the system, making support and security easier.
4: Cookie-related information
Cookies store sessions and save preference settings; these are small files, but very useful.
5: Support messages data
What you write on the ban21 Help or Contact page may also be stored to help understand problems later.
How data protection works
1: Secure storage
Data can be viewed only by a limited number of people; many users in Dhaka are connected with bKash or Nagad, so data access controls should be separate.
2: Risk mitigation rules
The system monitors unusual logins, multiple devices, or suspicious sessions, which increases your account security.
3: App-based security
In the ban21 App, session timeout and identity verification work; the same security rules apply even when using Rocket.
Cookies and session settings
1: Session cookie
These keep you logged in so you don't have to type the password repeatedly, making usage easier.
2: Preference cookies
Remembers language, view, and a few settings; users using Nagad or bKash also receive the same benefits.
Your rights
1: Right to view data
You can learn what information is kept; if needed you can send a request via ban21 Contact.
2: Right to correct incorrect
If your name or contact information is incorrect you can request correction; this helps support to work faster.
3: Request data deletion
If information is no longer needed, you can request deletion; after verification according to the rules, steps are taken.
4: Cookie control
Cookies can be disabled from browser settings, but some features may not work properly.
Practical tips
1: Use a strong password
Use at least 8 characters for your password; it's best not to use the same password elsewhere.
2: Be careful on public devices
If you share a computer, sign out; logging in from a cafe in Dhaka or another city is even more important.
3: Use only official links
When opening ban21 Login or ban21 App, verify the correct address to reduce the risk of fake pages.
