HOW WE HANDLE THIS

Our Approach to Data, Security and Account Integrity

These four areas cover the practical side of how we manage your account data, your wallet details, and your right to request changes — all within the scope of our legal obligations and your eligibility status.

Data Handling and Retention

We retain your account data only as long as your account is active or as required by our operational obligations. You can request a data summary through email support at any time.

Cookie and Session Policy

Our site uses session cookies to keep your account login secure and to remember your payment method preferences. No third-party advertising cookies are placed without disclosure.

Account Security Practices

Every login is verified via OTP sent to your registered mobile number. We do not store bKash, Nagad or Rocket PINs — your wallet PIN stays between you and your wallet provider.

Requesting Changes to Your Record

To update your registered mobile number or linked wallet, contact support via email with your account ID and a recent transaction reference for identity verification.

Common Legal Questions from Our Account Holders

These are the questions we get most often about how our legal terms apply, what your rights are, and what to do if something with your account or payment identity needs sorting.

Access depends on your local law and the eligible regions we support. It is your responsibility to confirm that using the platform is permitted where you are located before opening an account.

Wallet identity must match your account name. If there is a mismatch, your withdrawal will be held until verification is complete. Contact support with your account ID to resolve it.

Yes. Send a written request to our support email from your registered address. We process account closures and data removal within our standard operational timeline after identity is confirmed.

The version published on this page at the time you take any account action — deposit, withdrawal, or registration — is the version that applies. We notify you of material changes before they take effect.

No. Accounts are strictly single-user. Deposits via bKash, Nagad, or Rocket must come from a wallet registered in your own name. Shared or third-party account use may result in a suspension.

Raise it through the live chat or email support with your account reference. Our team reviews the specific clause and your account history before responding with a clear outcome.
