4.2 Average rating, 46,687 Reviews, 175,460 Active users and 99.5% uptime These numbers show how regularly the platform is used since 2019; logs, cookies and session data are used only to run the service
Many sites hide this information; here it is explained in plain language so you can understand what data is kept and for how long
When logging in, the system typically stores the IP address, device type, browser and timestamp to detect unusual access, especially when the same account attempts to sign in from Dhaka and another city simultaneously
Cookies and session tokens may also be stored; these keep the app open, prevent asking for the password repeatedly, and simplify two-step authentication
Device model, operating system and app version are recorded; this helps troubleshoot issues. On Android 8+ devices, installing the APK may require permission, and that is also part of security measures
Support team uses the same data to detect crashes, slow loads and invalid sessions; submitting a report leads to a faster response
Cookies remember language, login status and some preferred settings, so next time you don't have to set them again
You can disable cookies from browser settings, but some parts may slow down; the same applies to the 39BD app downloaded
General operational logs are normally kept for a limited time; if there are no issues, older records are reduced to avoid unnecessary data buildup
Logs related to security incidents may be kept longer because further investigation, comparison and verification are needed
Data no longer needed is reviewed separately to reduce storage and keep account data more organized
If you want to close your account, some records may remain for legal reasons; this is kept only for security and compliance
Not all staff see all records; access is limited by role, and sensitive parts are opened under separate rules
This reduces internal risk and makes tracking easier; who viewed what data and when can be determined
Access logs, device verification and secure session use can detect unauthorized access; when you return to the 39BD Login page, you will see these security steps more clearly
The most important part is that the system can flag when an unknown device logs in
If logs exist, the error time, device and app version are matched to determine whether the issue is network, device, or app configuration
Reports from Dhaka, Chattogram or Sylhet can reveal patterns; this comparison helps support reach the right place quickly
If someone detects suspicious activity, the incident is assembled by reviewing the relevant records; this helps protect the account, terminate the session and reduce risk
This work is also legally required, so privacy and security should be considered together as a good practice
If you want to know, correct, or restrict your data, you can contact support 39BD Contact Page Sending requests is easy, and Help SectionFAQ
