Which device IDs are collected
Access
Android data
The app runs properly on Android 8+ phones, and on older devices basic tracking also works; many users keep low data mode at night
Login
View by session
If you log in repeatedly on the same phone, the app can recognize the previous session; this makes it easy to separate suspicious activity when multiple logins come from Dhaka or Chittagong at the same time
When you first login to 520bd, this information is auto-read; you can later review cookies and permissions settings if you wish
How fingerprinting works
1. Device fingerprint match
Browser version, screen size and language settings are checked together; this helps reduce fake logins on the same account
2. Cookies and local storage
Cookies remember where you were on the site, so you don't have to enter the password repeatedly, and the session returns quickly
3. Behavior-based signals
Not major transactions, only navigation patterns and click speed are observed; this helps keep the 520bd App secure, especially on weak networks
If logging in from Dhaka office network or home Wi-Fi, this signal helps reduce unnecessary blocks, and when suspicious, only verification is required
