ck66 App Privacy Policy
This page clearly explains device IDs, security, and data protection for Dhaka users, so they know in advance what is included and what is not
Effective Date and Short Name
Effective date: August 2026, we open the app, login and security verification, limited device information is viewed
This keeps the account secure, and wrong logins are caught easily; not too much information is collected, because that is good practice
Which device IDs are collected
Only three types of IDs are seen; these are used for security and session matching
- Device model and Operating system
- App version and language setting
- Login time and IP pattern
Many Bangladeshi users change devices, so this information helps match old and new devices
How fingerprinting works
Here, browser fingerprinting is used very limitedly; the purpose is only to help detect suspicious access
We look at five signals such as screen size, language, and app behavior; by themselves these do not identify anyone
What opt-out controls exist
Most tracking can be reduced in two steps; changing settings requires no separate form
- Turn off diagnostics in app settings
- Clear cache after logout
This reduces session history, but security checks are not fully disabled; that balance is necessary
Third-party SDKs and security
Only four main SDKs are used; each SDK has been verified beforehand
Local payments such as bKash, Nagad, and Rocket provide Dhaka users quick verification; here sensitive information only travels encrypted
Data retention duration
General logs stay up to 30 days; suspicious security events may be retained for a few more days
After that, data is scrubbed and anonymized; keeping unnecessary history is bad practice, so it is avoided
Data protection, security, and GDPR
Data protection in the ck66 App is arranged in three levels: transmission, storage, and access, each with separate rules
GDPR means not just a word; how the user can view, edit, or delete their own data is also clearly stated
Once ck66 Register Registration speeds up security checks later ck66 Download More ck66 App The same rules apply to usage
Important information for Bangladeshi users
Many Dhaka and Chittagong users top up quickly with bKash, so only essential information is kept in payment history
If session verification with Nagad and Rocket is fast, account issues decrease; even on slow networks, APK installation and login are easier for many
