Effective date and brief policy

Effective date: July 2026. This ck66 App page states what data is kept for how long and where it is used

The policy is short, but clearly lists biometrics, device data, cookies, and account access separately, so reading from Dhaka isn't a problem

What kind of biometrics do we use

Many people want to know how fingerprint or face unlock works; in ck66 App these stay only inside the device, so they are not sent separately to the server

This runs on Android's built-in security layer, and you can disable it later from Settings

Fingerprint

When the fingerprint matches, quick access is granted; many Android users in Dhaka and Chittagong choose this option because it works in one step

  • Matched on the device
  • No separate cloud copy is kept

Data stays on the device

This part is the most important; the ck66 App biometric template is read, but it is restricted to local secure storage

That is, server upload is not required, so on slow networks your local login setup is not affected, even with a 3G connection

ck66 local device security
  • Data is verified on the device
  • Biometric data is not sent to the server
  • Settings stay intact even on poor networks

How cookies and sessions work

Cookies are just small text files in the ck66 App; these help maintain login sessions, language choice, and secure navigation

If any tracking data exists, it is also limited; users can clear the browser cache to start a fresh session

  • Language Preference
  • Last Login Time

How to disable biometric login

If you want, you can easily disable biometric login by opening the security section in Settings to see this option

If you ever change phones, you must re-authorize similarly to users of bKash or Nagad; the same flow exists for Rocket accounts, but biometrics are always optional

  1. Open Settings

    Go to the Security or Privacy menu, then find the biometric toggle

  2. Disable Permissions

    Turn off fingerprint or face unlock, then login with PIN

  3. Set up again on new device

    If you want on a new Android phone, you can enable it again; the task finishes in 2 minutes

User rights and legal basis

Bangladesh users have some basic rights; you can learn what data is stored, why it is stored, and when you can request deletion

This ck66 App policy works on these three bases: consent, legitimate access, and service security; if data correction is needed, write to support and they will guide you

  • Right to view your data
  • You can correct incorrect data
  • Requests to delete specific data can also be made
