How device tracking works in the 3sbd App
What data is seen
Session ID, device model, and browser information make sign-in easier
How long data is kept
Records used for specific purposes are kept for up to 90 days, then routinely reviewed
Why it's needed
This data is needed to detect abnormal logins, keep page loads stable, and provide faster support
If you log in from Dhaka
Security checks may increase when you switch networks in Dhaka or nearby areas
3sbd Login is quick to open on the same device; 3sbd APK users also receive the same policy after setup
Why device ID and session data are needed
Sign-in authentication
If you sign in from the same phone repeatedly you don't have to provide all information again
This reduces unnecessary obstacles, and wrong logins are detected
Security Alerts
If a new browser or suspicious IP is detected, additional verification may be required
This reduces account risk, especially on shared phones
Performance measurement
How fast pages load and where they stop are checked to maintain speed
The 3sbd App can run smoothly on low networks

What to do if you have concerns about fingerprinting
Browser fingerprinting means combining your phone's technical markers to read language settings, screen size, and time zone
The 3sbd App is used only to prevent fraud, not to collect personal chats; if a suspicious combination is detected, sign-in may be slower even inside Dhaka
If someone signs in on multiple devices, the security level increases accordingly, and this check helps before moving to familiar local payment routes like Rocket
How to change settings to disable cookies
Necessary cookies
Login, language, or session cannot be kept without these
If these cookies are disabled, some screens won't load properly
Analytics cookies
Small statistics are collected to understand which sections are opened most
This data does not reveal personal identity
Preferred cookies
Your language, theme, and last visited page are remembered
So you don't have to set the same thing repeatedly
Cookies can be reduced from browser settings; on mobile this takes two steps, and most users finish within 1 minute
How third-party SDKs work
Sometimes external SDKs are needed for logging, security, or analytics; they only perform specific tasks and do not access the entire account
3sbd App selects tools that serve clear purposes; if an older version is used, update messages may appear, especially during times with 6.7M+ active users
These signals help quickly search within 419+ titles, with small checks run regularly to maintain 99.6% uptime

How long data is kept
Login, security and support data are not kept for the same period as needed; that is kept; the rest unnecessary parts are removed
Operational records are typically 90 days, and security logs are deleted after a specified review; since 2016 this routine is quite tidy
Users may also raise separate questions about old data; answers are provided in DM or by email in clear language
