What Data Do We Collect?
Account & Identity Information
When you register with 57 bd, we collect your name, email address, mobile number, date of birth, and your current address within Bangladesh. This information is essential for creating your account and verifying your identity. Your National ID (NID) or passport details may also be required during the account verification process. This sensitive information is used solely for validation and security purposes and is stored with strict encryption. Your identity information is never sold to third parties.
Device & Browser Information
When you use the 57 bd platform, your device type, operating system, browser name and version, screen resolution, and IP address are collected automatically. This information is used primarily to ensure platform compatibility and resolve technical issues. For mobile app users, device ID and push notification tokens may also be collected. Your geographic location is verified only to confirm that the service is being accessed from Bangladesh — we do not perform precise GPS tracking. Device information also helps with security analysis and improving the overall user experience.
Payment & BDT Transaction Data
When you make a deposit or withdrawal on 57 bd, we record your payment method (bKash, Nagad, Rocket, bank transfer, etc.), the transaction amount (Bangladesh Taka / BDT), and the date and time of the transaction. Full payment card numbers and mobile banking PINs are never stored on 57 bd's servers. Transaction history is used solely for account verification, dispute resolution, and anti-money laundering purposes. Certain financial records are required to be retained for a specified period in accordance with applicable Bangladesh Bank regulatory guidelines.
Platform Usage Data
Which games or sports events you participate in on 57 bd, how long your sessions last, which pages you visit most, and which bonus offers you use — all of this behavioral data is logged automatically. We use it to improve our service quality, deliver personalized offers, and identify suspicious activity. By analyzing your sports preferences, we can highlight relevant events and promotions for you. This data is always analyzed separately from your personal identity and is used solely for platform improvement.
What Is Your Data Used For?
Service Operations & Improvement
The primary use of your collected data is to keep all 57 bd services running smoothly. Account login, deposit processing, betting history storage, and bonus application each require specific information to function. We regularly analyze user feedback and platform usage patterns to improve our services. Existing user behavior data is reviewed before rolling out new features. Your information is never used for any personal gain and is always directed toward giving you the best possible experience.
Communications & Notifications
57 bd may use your email or mobile number to send important account notifications, transaction confirmations, security alerts, and relevant promotional offers. Your consent will be obtained before sending promotional messages, and you can unsubscribe at any time. Transaction and security notifications are essential and will always be sent — these cannot be opted out of. We never send spam or irrelevant third-party messages. All contact information is handled with strict confidentiality.
Fraud Prevention & Legal Compliance
Your data is used to detect and prevent fraudulent activity, combat money laundering, and ensure responsible gaming. Retention of certain data is mandatory to comply with applicable laws and regulatory requirements in Bangladesh. Suspicious transactions are automatically flagged and reviewed by our security team. No data is disclosed to government agencies without a valid court order or lawful request from law enforcement. Data that is no longer needed following security analysis is deleted within defined timeframes.
Cookies & Tracking Technologies
What Are Cookies and Why Do We Use Them?
Cookies are small text files stored in your browser or on your device that help improve your experience. 57 bd uses three types of cookies: essential cookies (for login sessions and security), functional cookies (to remember your preferences), and analytical cookies (to measure platform performance). All cookies except essential ones can be controlled or disabled through your browser settings. Disabling cookies may limit certain features, but core services will remain accessible. We do not use tracking pixels or fingerprinting technologies for third-party advertising purposes.
Manage Cookies
You can clear cookies or stop accepting them at any time through your browser settings. Most modern browsers offer cookie management options under Tools > Settings > Privacy or a similar section. On mobile apps, data collection can also be limited through the privacy settings. Session cookies are automatically deleted when you close your browser, while persistent cookies have a set expiry date. Your privacy preferences matter to us, and we always respect your control.
How Long Is Data Retained and How Is It Protected?
Retention Period
Data for active accounts is retained for as long as the account remains open. After closure, financial transaction records may be kept for up to five years to meet legal obligations. Analytical and behavioral data is generally deleted automatically after 12 months. No data is retained beyond what is necessary, and once the defined retention period ends, data is securely destroyed.
Encryption & Security
All your data is transmitted via SSL/TLS encryption and stored on our servers using AES-256 encryption. Our server infrastructure undergoes regular security audits. Firewalls, intrusion detection systems, and two-factor authentication are in place to prevent unauthorized access. In the event of a data breach, affected users will be notified within 72 hours.
Internal Access Controls
Only authorized 57 bd staff can access your data, and only when required for their specific role. Every access is logged and regularly reviewed. Staff receive ongoing data privacy training and operate under strict confidentiality agreements. A least-privilege policy is enforced to prevent unnecessary internal access.
Backup & Recovery
Your data is stored in regularly encrypted backups to enable fast service recovery in the event of a technical failure. Backup servers are held to the same high security standards as our primary servers. Restoring data from backups requires a strict authorization process, and every recovery operation is fully documented.
Data Sharing with Third Parties
When and With Whom Is Your Data Shared?
57 bd never sells your personal information or shares it with any advertising agency. However, limited data sharing with specific service partners is necessary — for example, payment processors such as bKash, Nagad, Rocket, and banking partners. These partners receive only the information required to perform their specific function. All third-party partners are bound by data protection agreements consistent with our privacy policy. Where legally required, data may be disclosed in compliance with valid court orders or regulatory directives, and we will notify you in advance wherever possible.
International Data Transfers
57 bd's primary server infrastructure is located in the Asia-Pacific region, and data belonging to users in Bangladesh is processed locally wherever possible. If data must be transferred to servers in another country, equivalent data protection standards are ensured in that jurisdiction. Encrypted connections are always used for international transfers. Data is not shared broadly with any country without the user's explicit consent. We respect data sovereignty and comply with Bangladesh's data protection guidelines.
