DATA HANDLING PRACTICES

How We Protect and Manage Your Information

We apply standard security measures to your account data and payment records. Here is how the key areas work in practice — from how your bKash or Nagad details are stored to how long we keep your session history.

Payment Data Security

Your bKash, Nagad and Rocket transaction references are stored in encrypted form. We never hold your full mobile wallet PIN or password — those stay with the wallet provider.

Cookie and Session Data

Session cookies keep you logged in across your mobile browser and desktop without re-entering credentials each time. You control cookie acceptance through your browser settings.

Account Access Logs

Every login to your tk4 account is timestamped and tied to a device fingerprint. If we detect a login from an unfamiliar device, your account may be flagged for verification.

Data Retention and Deletion

We keep your account data for as long as your account is active and as required by applicable regulations. Submit a deletion request and we will confirm what can be removed and when.
