Types of Data Collected
When you register and use services on the 399bit platform, we collect various types of information needed to provide you with a safe and personalized experience. Each piece of data is collected for a specific purpose, and we avoid collecting anything unnecessary. The main categories of information we collect are outlined in detail below.
Account Information
Your name, mobile number, email address, and date of birth are collected at registration. This information is essential for verifying your identity and managing your account.
Device & Browser Information
Your device type, operating system, browser version, and IP address are collected automatically. This information helps us maintain platform security and detect fraudulent activity.
Payment & BDT Information
Payment information required for BDT transactions is collected. bKash, Nagad, and other mobile banking details are not stored directly — only transaction records are kept.
Usage Data
We collect behavioral data including the pages you visit, the games or events you participate in, and how long you are active on the platform. This information is used to improve our services and deliver a more personalized experience.
We never collect a full copy of your national ID or your bank account PIN. Only the minimum information required for identity verification is stored. Your data is always kept encrypted and protected against unauthorized access.
How We Use Your Data
399bit uses your data only for lawful and clearly defined purposes. We believe transparency is the foundation of trust, so we have set out each purpose openly below. Your data is never sold to third parties or misused for advertising.
Account Management
Your data is used to create, verify, and secure your account. Login, password reset, and two-factor authentication all rely on this information. It is also used to detect unauthorized access.
Financial Transaction Processing
Payment information is required for deposits, withdrawals, and bonus distributions. Records of BDT transactions support financial security and dispute resolution. Every transaction is processed through a secure gateway.
Service Improvement
By analyzing how you use the platform, we work to make it more intuitive and engaging. Understanding which sections users spend the most time on helps us improve content and features accordingly.
Communication & Notifications
Your contact details are used to send important account notifications, security alerts, and promotional offers. You can opt out of promotional messages at any time.
We also monitor your usage data to promote responsible gaming. If any user's behavior shows signs of risk, we may take supportive action. Data may also be used to meet legal obligations and prevent fraud.
Cookies & Tracking Technologies
Cookies and similar tracking technologies are used to keep the 399bit website and app running properly. Cookies are small text files stored in your browser that help recognize you on return visits. We use three types of cookies.
Essential Cookies
These cookies are essential for maintaining your login session, storing security tokens, and remembering your language preference. The platform cannot function properly without them, and they cannot be disabled.
Analytics Cookies
These cookies are used to understand visit counts, popular pages, and user navigation paths. All data collected is completely anonymized and is not used to identify individuals.
Preference Cookies
These cookies remember your theme preferences, notification settings, and language selection. You can clear them at any time from your browser settings.
You can manage cookies at any time through your browser settings. Keep in mind that disabling essential cookies may affect the functionality of certain features. We do not use any third-party advertising trackers, and your browsing activity is never followed across other sites.
Data Retention & Security Measures
399bit follows industry-standard technologies and practices to protect your data. All data stored on our servers is secured with AES-256 encryption. Every data transmission is handled via SSL/TLS protocols, keeping your information safe from third-party interception.
Secure Servers
All data is stored in a controlled environment with unauthorized access fully restricted.
Access Control
Only authorized personnel can access specific data, and all activity is logged.
Regular Backups
Automated backups are performed to prevent data loss, and a recovery plan is always in place.
Security Audits
System security is maintained through regular vulnerability assessments and audits, with prompt action taken against emerging threats.
Your data is not retained beyond what is necessary. After an account is closed, information is securely deleted within a defined period in accordance with legal obligations. Financial transaction records may be retained for the period required under applicable Bangladesh law. In the event of a security breach, we will promptly notify affected users and take the necessary protective measures.
Sharing Data with Third Parties
399bit never sells your personal data or shares it with third parties for advertising purposes. However, in certain situations, limited information may be shared with trusted partners — these are clearly outlined below. In every case, only the minimum data necessary for service operations is shared.

Necessary information is shared with authorized payment gateways and mobile banking providers to process financial transactions. These partners are contractually bound to comply with their own privacy policies and security standards.

All our third-party partners are committed to upholding international data protection standards, and we have written agreements in place with each of them. Should any partner fail to meet these standards, we reserve the right to terminate the relationship.
