DATA HANDLING STANDARDS

How We Protect and Manage Your Information

We apply security measures at every layer of your account — from the moment you log in on your phone to the point your bKash or Nagad withdrawal is confirmed. Here is how we handle the four areas that matter most to your privacy.

Account Security

Your account is protected with OTP verification on login. Session tokens expire automatically after inactivity, so an unattended phone cannot stay logged in indefinitely.

Cookie and Device Data

We use session cookies to maintain your login state and remember your last-used payment method. You can clear these from your browser settings at any time without losing your account.

Data Retention

Active account data is kept while your account is open. After closure, we retain records only as long as required by applicable obligations, then delete or anonymise them.

Your Rights and Requests

You can request to view, correct, or query the deletion of your personal data by contacting support. We will confirm receipt and handle your request in line with applicable rules for your region.

Common Questions About Your Data

Real questions from people using 4666 — answered plainly so you know exactly where you stand.

We collect your name, mobile number, and the payment reference from your bKash, Nagad, or Rocket transaction. Device identifiers are also logged to secure your session.

Yes. Submit a deletion request through support. We will process it in line with applicable regional rules — some records may be retained for the period required by law before full deletion.

We keep records for the period required by applicable obligations after account closure. Once that period ends, data is deleted or anonymised. You can ask support for details specific to your region.

No. We store only the transaction reference number, not your wallet PIN or full credentials. Payment authentication happens directly through your wallet app, not through our platform.
