01 What Information We Collect

399dt collects certain personal information to keep the platform running smoothly and to provide you with the best possible service. We only collect what is genuinely needed — nothing more.

Payment information Mobile Banking/Nagad/Rocket number Deposit & Withdrawal Processing

The above information is collected directly from you during registration and automatically during your use of the platform. No data is collected without your knowledge.

Please note: 399dt never collects or stores your password, full payment PIN, or any other sensitive security credentials.

02 How We Use Your Information

399dt uses collected data only for specific purposes. We never sell your information for commercial gain or transfer it to third parties — unless required by law.

  • Account Management: To ensure secure registration, login, and account protection.
  • Transaction Processing: To process deposits, withdrawals, and bonus settlements.
  • Customer Support: To resolve your questions and complaints quickly.
  • Security verification: To prevent fraud, money laundering, and account hacking.
  • Responsible Gaming: To monitor your gaming habits and identify potential issues early.
  • Legal Compliance: To comply with applicable laws and regulatory requirements.
  • Service Improvement: Analytics data is used to improve the platform experience.
399dt's Commitment: Your data will never be sold to advertising companies or data brokers.

03 Who your data is shared with

399dt respects your privacy. That said, there are certain situations where sharing your information becomes necessary. Below is a clear breakdown of when and with whom your data may be shared:

  • Payment providers: Mobile banking providers such as Mobile Banking, Nagad, and Rocket receive only the minimum data required to verify transactions.
  • Game Software Providers: For Live Casino or slots games, technical data (session ID) may be shared — no personal information is involved.
  • Legal Authorities: 399dt is legally required to provide information in response to valid court orders or requests from regulatory authorities.
  • Fraud Prevention: Limited data may be shared with third parties for anti-fraud and KYC verification purposes.
All third parties with whom data is shared are contractually bound to uphold 399dt's privacy standards.

04 Cookie Policy

The 399dt website and app use cookies to improve your experience. Cookies are small text files stored in your browser. 399dt uses the following types of cookies:

  • Essential cookies: For maintaining login sessions and core platform functionality. These cannot be disabled.
  • Functional Cookies: To remember your preferred language and settings.
  • Analytics cookies: To understand which parts of the platform are used most — fully anonymized data only.
  • Security cookies: To prevent CSRF attacks and session hijacking.

You can clear cookies or stop accepting new ones at any time through your browser settings. However, disabling essential cookies may cause certain 399dt features to stop working properly.

05 How long your data is retained

399dt does not retain your data longer than necessary. All information is kept while your account remains active. Once your account is closed or deleted, how long data is retained depends on applicable legal obligations.

  • Transaction Records: Retained for up to 5 years in accordance with financial regulations.
  • Gaming Logs: Retained for 3 years for dispute resolution.
  • KYC Documents: 5 years in secure storage after verification is complete.
  • Support Chat Logs: 2 years for improving customer service quality.
  • Marketing preferences: Until you withdraw your consent.
Once the retention period expires, data is securely deleted or fully anonymized.

06 Your Rights

399dt believes you should have full control over your own data. That's why we provide you with the following rights:

  • Access Rights: You may request a copy of the personal information we hold about you.
  • Right to Rectification: You can request corrections to any inaccurate or outdated information.
  • Right to erasure: You may request permanent deletion of your data, provided there are no legal obligations requiring its retention.

  • Right to portability: You may request a copy of your data in a machine-readable format.
  • Right to Object: You can opt out of marketing communications or profiling at any time.

07 Security measures

399dt protects your data using industry-leading security measures. Our security infrastructure operates across multiple layers, so that even if one layer is compromised, your information remains protected.

  • TLS 1.3 / SSL 256-Bit Encryption: All communications are encrypted.
  • Two-factor authentication (2FA): OTP verification at login.
  • Firewall & DDoS protection: Protecting servers from external attacks.
  • Regular security audits: Periodic penetration testing conducted by third parties.
  • Data Backup: Encrypted backups stored on geographically separate servers.
  • Access Control: 399dt staff can only access information required for their specific role.

Keep in mind, however, that no method of transmission over the internet is 100% secure. Always use a strong password and never share it with anyone.

08 Minor Protection

399dt strictly prohibits anyone under 18 from using the platform. Age is verified during registration, and additional documentation may be requested in cases of suspicion.

If we become aware that a minor has created an account, that account will be closed immediately and all associated data will be deleted.

If you know of a minor using 399dt, please contact our support team immediately.

09 Third-party links & services

The 399dt platform may integrate third-party game software or technology services. These services have their own privacy policies and operate outside of 399dt's control.

We vet all third-party partners and establish data protection agreements with them. Even so, 399dt is not responsible for the privacy practices of third parties. We recommend reviewing their own policies before using any external service.

  • Game providers only receive session-related technical data.
  • Payment gateways only receive the minimum information necessary to confirm a transaction.
  • Analytics tools use fully anonymized data.
