3999bd Privacy Policy — How We Handle Your Information

3999bd takes the privacy of its members in Bangladesh very seriously. We understand that sharing personal information with any platform is an act of trust — and honoring that trust is our responsibility.

This Privacy Policy explains:

• What types of data 3999bd collects and when.
• How your collected data is used.
• How your data is protected and how long it is retained.
• Your rights as a member.
• Where to reach us if you have an issue.

3999bd's Privacy Policy was last reviewed in January 2026. Members will be notified in advance of any future changes.

3999bd collects information in three main ways — directly from what you provide, automatically through your use of the platform, and from third-party verification agencies.

3999bd never collects your bank card number or full financial credentials. Your mobile banking PIN or OTP will never be requested — any such request is a fraudulent attempt using 3999bd's name.

3999bd uses the information it collects solely for lawful and specific purposes. No data is ever used beyond what it was originally collected for.

• For account creation, verification, and security.
• To process deposits, withdrawals, and transactions.
• For customer support and issue resolution.
• To prevent fraud, money laundering, and unauthorized access.
• To notify members of relevant offers and bonuses (only with your consent).
• For anonymous analytics to improve the platform.
• To meet legal and regulatory obligations.

3999bd only sends promotional messages to members who have explicitly given their consent. You can turn off marketing communications at any time from your settings.

3999bd does not sell your data to third parties. However, limited data sharing may occur in certain circumstances:

• Payment providers: Only the necessary information is shared with bKash, Nagad, and Rocket to process your transactions.
• Identity Verifiers: Only the minimum required information is provided to approved verification bodies for the KYC process.
• Law Enforcement: Information may be disclosed in response to a lawful order from a court or authorized government authority.
• Technology partners: Server hosting and security service providers operate under strict confidentiality agreements.

In each of the above cases, only the minimum necessary data is shared, and all relevant parties are contractually bound to uphold privacy standards equivalent to those of 3999bd.

3999bd ensures data protection at both the technical and administrative levels. Our security measures follow the highest industry standards.

• TLS 1.3 encryption is applied to all data transmissions.
• Passwords are never collected in plain text — only hashed versions are stored.
• Server access is governed by strict role-based access controls.
• Regular security audits and penetration testing are carried out.
• Automated 24/7 monitoring runs continuously to detect suspicious activity.
• Data backups are stored on secure, geographically separate servers.

Keep in mind — no one can guarantee 100% security on the internet. 3999bd takes every precaution possible, but on your end, using a strong password and enabling two-factor authentication is equally important.

3999bd uses cookies on its website and app. Cookies are small text files stored on your device that help improve your browsing experience. We use three types of cookies:

• Essential Cookies: To maintain login sessions and ensure security. These cannot be disabled.
• Functional Cookies: Used to remember your preferences (such as language settings). Disabling these may cause certain features to stop working.
• Analytics Cookies: Anonymous data is collected to understand which parts of the platform are used most. This can be disabled through your browser settings.

3999bd does not use any third-party advertising tracking cookies. Your browsing data is never shared with ad networks.

As a member of 3999bd, you have several important rights over your personal data. To exercise any of these rights, please get in touch with our support team.

3999bd does not retain data longer than necessary. Different types of data have their own defined retention periods.

• Account Information: For as long as your account remains active, and up to 5 years after closure as required by law.
• Transaction Records: Financial regulations require a minimum retention period of 7 years.
• Customer Support Communications: 2 years after issue resolution.
• Activity Logs & Session Data: 1 year for security analysis purposes.
• Marketing communications consent: Until you opt out.

Once the retention period expires, data is securely deleted or anonymized so that individuals can no longer be identified.

If you have any questions, concerns, or requests regarding this Privacy Policy or your personal data, please contact 3999bd directly.

• Email: support@3999bd.world
• Live Chat: 24/7 Bangla support is available.
• Response time: Privacy-related requests are typically responded to within 72 hours.

Once a complaint is raised, 3999bd takes it seriously and works to investigate and resolve it promptly. Our goal is to earn your trust — not avoid accountability.
