Device ID and CK66 login information

Device Identifier

CK66 App checks phone model, OS version and app ID to keep login stable, and helps detect suspicious sessions

Sign-in Security

During CK66 login, location, session time and browser token are checked; many Dhaka users sign in again in 2 minutes

Fingerprint Signals

Signals such as screen size, language and time zone help detect system risk; this is a real part of data protection

How cookies and analytics work

Cookies come in three types: Session, Preferences, and Performance; these help CK66 App remember your language, theme and preferences

Analytics show which screens are opened most, so navigation and loading are more streamlined, especially on slow networks

Small conveniences for local users

Preferences remembered before logging into bKash, Nagad and Rocket
Night load and day load are measured separately
Three main cookies are enough to open mobile pages

Opt-out and control

If you disable analytics cookies, CK66 App will still run, but some personal settings may not be remembered

Browser settings, app permissions and device cleanup work together so data protection remains in your hands

Third-party SDK and data protection

SDK Limits

Some SDKs work only for performance and crash reporting; only necessary technical signals are sent without personal data

Performance Report

Analytics reports contain aggregate data on which city is loading more, so the team tunes accordingly

SDK limits during CK66 Register or CK66 Download prevent new user data from being unnecessarily spread

Data Retention Period

Session data generally lasts up to 30 days; security-related logs may be kept longer if risk analysis is needed

Old cookies and temporary files are refreshed within 90 days; this keeps the account light and the CK66 App fast
