When you open an account, place a bet, or make a payment on mambaji, certain information comes to us in the process. This page explains in plain language what that information is used for, how it is kept secure, and what rights you have over it.
All your data is protected with 256-bit SSL encryption — the same technology used by banks. Everything from your name to your payment details is fully secured.
Your mobile number, email, and personal information are never sold to advertisers or third parties. Not ever. That is mambaji's core promise.
Credit or debit card numbers, CVV codes, and expiry dates are never stored on mambaji's servers. All payment processing is handled through a certified gateway to which we have no direct access.
You can view, update, or delete your personal data at any time — just contact support and it will be handled within 24 hours.
If any unusual activity is detected on your account, the system automatically sends an alert. Suspicious logins or transactions are flagged instantly.
Once your account is closed and the required legal retention period has passed, your personal data is permanently deleted. We do not hold data indefinitely.
