What are the duties
Where data goes, who sees it, and how long it stays are set by policy
Clear Policy Start
This page explains the 520bd App privacy policy and how data is stored on the platform that has been operating since 2015
The information you provide during login, registration, and support conversations is used under the same rules for users in Dhaka, Chattogram, and other parts of the country.
Data Protection Officer's Duties
What it protects
Account information, device data, and transaction logs are protected at separate levels
What it monitors
Unusual logins, suspicious access, and verification steps are monitored
The information submitted during 520bd Login or 520bd Register is also limited; no extra data is collected unless necessary
This is the core of the 520bd App privacy framework; see the next section for when to contact the DPO
When to contact the DPO
If you see suspicious messages while logging in at night, report to the DPO; similarly, contact if you have questions about installing the 520bd APK
If after paying with bKash, Nagad, or Rocket the information does not match, report promptly; the security team will review it the same day
Suspicious Notification
If you see an unfamiliar alert, stop and send to the DPO
Device Issues
If the app behavior changes, it's good to report; it also applies to old phones
Account Match
If you notice a difference between payment history and profile, report immediately
What to Include in the
Your username, the issue, and when it happened; three items; screenshots are even better
Which part of the 520bd App has a problem; also write it, such as login, registration, data verification, or encryption-related notices
Profile Information
Provide the account name and registered number; do not write the full number
Screenshot
Send the visible part of the problem; this makes verification faster
Time Note
When it happened, that's most useful; notes within 10 minutes are enough
How quickly you'll receive
The first answer to common questions usually comes within 24 hours; urgent security issues are handled first
The 520bd App data protection team works quickly on small cases; many users in Dhaka get replies before noon
Support Queue
In the message queue, work proceeds by a fixed number
Security Case
If a security risk exists, it is resolved first
Follow-up
If needed, more information may be requested
Appeal and Next Steps
If you're not satisfied with the answer, you can request a second review of the DPO case
If needed, use the 520bd Register page or 520bd Help to create a new ticket; it will be linked to the existing case
Reevaluation
Old decisions can be revisited; in most cases, gaps are found
Record Protection
Your request history is kept in a separate file
Know Your Rights
You have the right to know what is stored
Encryption and Security
Data in the 520bd APK travels via encrypted paths, so no one can read it in transit
Risks are reduced on public Wi-Fi, but many in Dhaka use mobile data, which is even better
Secure Session
Login session uses separate token; unfamiliar device is detected quickly
Data lock
Profile data stays separate; personal data does not mix easily
Warning signs
If any anomaly is detected, the system marks it; review starts
