Where ban21 App data goes
This page uses sign-in, session status, and device information in the ban21 App to provide secure access for your privacy and data protection.
In Dhaka, many people log in from mobile, and login history quickly matches on bKash, Nagad, and Rocket-based accounts.
Analytics service
It shows which page was opened, making load time and errors easier to capture.
Device information
Model, browser, and screen size are stored; this strengthens account security.
Session monitoring
Login status from one device to another is matched; suspicious access is detected quickly.
Error report
Crashes and slow pages are tracked; solving the issue takes 3 steps.
What information is tracked
Account-related logs
Login time, device IP, and password change history may be kept; unusual activity is detected.
If ban21 Login fails repeatedly, a temporary lock may occur for security.
User behavior
Which menus were opened, how long you stayed, and where you pressed are tracked; this helps improve the experience.
Personal notes are not read
- Page load speed is measured
- Failed sign-ins are tracked separately
- New device detected
- Personal notes are not read
IP masking rules
Partial masking
Some logs do not include the full IP; partial addresses are kept to maintain security, and analysis also continues.
This is especially useful in Bangladesh when a mobile network changes; the same user is identified even on different networks.
Location matching
From sessions originating in places like Dhaka, Chittagong, and Sylhet, different patterns are observed, reducing fraudulent access.
Using ban21 APK, this security works the same on Android as well.
Opt-out and control
Ways to disable tracking
Some analytics can be disabled from browser settings; clearing cookies also reduces monitoring of certain parts.
However security logs are not completely disabled; those are needed to protect the account.
Your preferences
Notifications, session, and device permissions can be managed separately; after registering with ban21, you can change these in profile settings.
The same security level remains when funding with Nagad or Rocket; transaction data is processed through different paths.
Retention time and deletion
Retention policy
Data is kept as long as necessary, then deleted or anonymized at a specified time.
Security logs are usually kept to understand the type of issue; different rules apply for financial information.
Record update
When account information changes, parts of old records may be retained; this makes fraud analysis easier.
To finish quickly on mobile, find the word ban21 Download on the official page and access from there.
Security checklist
Strong password
Use at least 8 characters, mixing numbers and symbols.
Same device
Keep login on your own phone; do not leave sessions open on unfamiliar phones.
Notifications on
Watch for new logins; suspicions detected within 1 minute.
Regular review
Settings check once a month; disable old permissions
