The measures 399bey takes to keep your data secure — even across millions of daily transactions.
All communication from your mobile device to 399bey's servers is encrypted with 256-bit SSL. Nobody in between can read your data — that is a fundamental security commitment.
Many digital platforms sell user data to advertisers. 399bey has never done this and never will. Your data is yours — we only use it to provide our services.
Even 399bey's own staff cannot access all of your information. Employees in each department can only view the data relevant to their specific role — this is a core principle of our security framework.
399bey's servers and network are monitored around the clock. Any unusual activity — such as simultaneous login attempts from multiple locations — is detected automatically.
Independent security experts regularly audit 399bey's systems. Any vulnerabilities found are resolved quickly — before players are ever affected.
Data is automatically deleted once the retention period expires — no manual intervention required. This ensures that unnecessary data is never held longer than it should be.
Digital security awareness is growing in Bangladesh — and that's a very positive development. Here's a closer look at how 399bey keeps your data protected.
When depositing via bKash or Nagad, 399bey never sees your mobile banking PIN. Only the transaction confirmation message is received — no PIN or password. This is handled entirely by the mobile banking provider's own security system.
The national ID image you provide for KYC is used solely for age and identity verification, and only for a limited period. Your ID details are never used for advertising or marketing purposes.
Your mobile number is used solely for 399bey's own notifications and security purposes. It is never shared with any third party — so unexpected marketing calls are simply not something you need to worry about.
399bey does a lot to keep you safe, but security is a shared responsibility. A few simple habits on your end can make your account significantly more secure.
Alongside this Privacy Policy, 399bey's Terms & Conditions and Responsible Gaming Policy— also worth reading. Together, all three documents give you a complete picture of your relationship with 399bey. This platform is not available to anyone under 18 years of age.
