Frequently Asked Questions

Frequently asked questions about our Privacy Policy

The short answer is yes — the protection is real, not just a claim.

Your personal information is protected on two levels. First, data transmitted from your device to 399btd's servers is secured with 256-bit SSL encryption via TLS 1.3 – the same standard used by banks. Second, all data stored on our servers remains protected with AES-256 encryption.

Regarding financial information – your bKash or Nagad number is stored for payment processing purposes but is never held in plain text. No card numbers or PINs related to payment gateways are stored on 399btd's servers. An AI monitoring system runs around the clock to automatically detect suspicious logins and unusual transactions.

The most reliable place to find 399btd promotions is directly on the 399btd rewards and offers page. The latest deals are also displayed in the banner section of the homepage after you log in.

Here's the general update schedule: the daily cashback offer resets at midnight every day. The weekly reload bonus refreshes every Monday. Seasonal or special tournament offers (such as IPL, World Cup, and Eid) are announced separately.

Enable push notifications or email alerts in your account settings to stay up to date on all the latest offers. Promotional notifications fall fully under our personal data policy – no spam is ever sent without your consent.
