How We Protect Your Data and Account Rights

Your account data is handled under a clear retention and access framework. We collect only what is necessary to operate your account — identity verification details, transaction records tied to bKash, Nagad or Rocket activity, and device access logs. You can request a summary of what we hold at any time by contacting support in writing. Account security is maintained through OTP verification at login and on sensitive account changes, so unauthorised access attempts are flagged before they affect your wallet.

Data Retention

We retain account and transaction data for the period required by applicable policy. After account closure, data is held only as long as legally necessary before deletion.

Cookie Use

Cookies on tk4 support session continuity across mobile and desktop. They do not store payment credentials. You can manage cookie preferences through your browser settings.

Access Requests

You have the right to request access to the personal data we hold on your account. Submit a written request through live chat or email and we will respond within a reasonable timeframe.

OTP Security

Login and account changes on tk4 require OTP confirmation to your registered mobile number. This protects your wallet balance and linked payment methods including Nagad and bKash.
