Account Information
Name, phone number, login information, and language preference are stored; without these, sign-in, security verification, and remembering settings are difficult.
If you want, you can correct incorrect profile information; this usually takes no more than 2 minutes.
Device and Session
Data on which phone, which browser, and which session is active is stored to help detect unauthorized access.
The same security rules apply to accounts linked from Rocket or Nagad.
Cookies and Local Storage
Cookies automatically keep your language, page preferences, and session, so you don't have to set them again.
On mobile this is quite handy, especially on Dhaka's busy networks; once logged in you can feel the speed.
