How ck4 App Privacy Policy works
The ck4 App collects only the necessary information for use, data is processed for security and technical support
In Dhaka, many people track transactions with bKash or Nagad; session data is only seen in the authorized service flow and does not spread outside
Name and Contact
Registration, login and support tickets require this information
These are used to verify your account and send messages
Device and browser information
Model, OS, and session time are recorded
This makes it easier to detect unusual logins
Payment reference
Reference numbers are kept for bKash, Nagad, and Rocket
These are used to reconcile transactions
How cookies and targeting work
Cookies remember language settings, session state, and preferences
Advertising partners receive limited identifiers; they tailor ads based on prior visits, device type, and location signals
- Session cookie: keeps you logged in
- Preference cookie: language and layout kept
- Analytics cookie: shows which pages are most viewed
What is shared with advertising partners
Only matching signals are shared, not personal messages
Email content, passwords, and account notes never go to ad networks; in ck4 Login and ck4 Register flows this separation is strictly enforced
