This page explains, in plain English, what information is collected when you use BB4, how it is used, where it is stored, and how it is kept secure.
Key Information: By using BB4 (bb4.im), you agree to this Privacy Policy. If the policy is updated, the revision date will be noted on this page.
The Core Pillars of BB4's Data Protection
All data transmitted across BB4's site and app is encrypted with 256-bit SSL — the same level of protection used by banking websites.
BB4 never sells your personal information to third parties. Your data is kept securely on BB4's own servers.
Only authorised BB4 staff can access data, strictly on a need-to-know basis. Every access is recorded in the system logs.
User data is stored in encrypted databases. Passwords are never kept in plain text.
BB4 only collects the information genuinely needed to provide its services — nothing more.
BB4's security measures are reviewed and updated on a regular basis to ensure protection against emerging threats.
This privacy policy applies to the website, mobile app, and all related services operated by BB4 (bb4.im). By using BB4's services, you automatically agree to this policy.
BB4 takes your privacy seriously. We want you to know exactly how your information is being used — there's nothing hidden here. This page is written in plain English so that any user can understand it.
BB4 complies with international data protection standards. User information is managed in accordance with the guidelines of our licensing authority. This policy may be updated at any time — any changes will be reflected by an updated date on this page.
BB4 collects two types of information — what you provide directly, and what is generated automatically when you use our services.
| Data Type | What's Included | Why We Collect It |
|---|---|---|
| Identity Information | Full name, date of birth, national ID number | Account Verification (KYC) |
| Contact Information | Mobile number, email address | Notifications & Support |
| Financial Information | BKash/Nagad/Rocket number, transaction history | Payment Processing |
| Usage Data | IP address, device information, login timestamps | Security Monitoring |
| Gaming Information | Betting history, game sessions, win/loss records | Account Management |
| Cookie Information | Browser session, preference settings | Site Functionality |
BB4 never collects unnecessary information. For example, BB4 will never ask for your social media passwords, bank card PIN, or any similarly sensitive data. If anyone claiming to be BB4 asks for such information, it is not BB4 — contact support immediately.
BB4 uses the information it collects solely for specific, defined purposes. The key purposes are outlined below.
BB4 never sells your information to advertisers or uses it for third-party marketing. If you'd prefer not to receive promotional emails or notifications from BB4, you can turn them off in your account settings.
How long BB4 retains your data depends on the type of information. All data is kept for as long as your account remains active. Even after account closure, certain data may be retained for a set period to meet legal obligations.
Financial transaction records are typically retained for 5 to 7 years, in line with international anti-money laundering regulations. Login logs and security records are generally kept for 1 to 2 years. Gaming history is retained for the duration of your account — and deleted after a minimum period following account closure.
BB4's servers are protected with firewalls, encryption, and regular backups. In the event of a security breach, BB4 will notify affected users as quickly as possible.
BB4's site and app use cookies — small text files stored in your browser that help BB4 remember your preferences.
You can disable cookies through your browser settings, though some site functionality may not work properly as a result. BB4 does not use any external advertising cookies.
As a BB4 user, you have several rights regarding your own information. To exercise any of these rights, please get in touch with BB4 Support.
You may request a summary of the information BB4 holds about you. Contact Support with your request and BB4 will send you a summary.
You can request corrections to any inaccurate or outdated information — including your name, contact number, or any other details on your account.
You may request account closure and deletion of your data. However, certain information may need to be retained for a specified period due to legal obligations.
If you'd prefer not to receive promotional messages or emails from BB4, you can opt out through your account settings or by contacting support.
To exercise any of these rights, reach BB4 via live chat or support@bb4.im. We typically respond within 3 business days.
BB4 employs multiple layers of technical and organizational measures to protect your information. These work together to safeguard your data against potential threats.
BB4's servers and network are protected by firewalls. All web traffic runs over HTTPS, meaning every exchange between your browser and BB4's servers is encrypted. Passwords are never stored in plain text — they are converted through a one-way hashing process so that no one can read them.
BB4's data centers are also physically secured — server rooms are accessible only to authorized personnel. Regular backups are taken to prevent data loss in the event of any technical issue.
Security works both ways — while BB4 has all the necessary safeguards in place, there are steps you can take as a user too. Use a strong password and never share it with anyone. BB4 will never ask for your password via email or chat — if someone does, it's a scam. Enabling Two-Factor Authentication adds a significant extra layer of protection to your account.
Always log out of your session after using BB4 on an unfamiliar device or public Wi-Fi. You can review your login history in your account settings — if you notice anything unusual, change your password immediately and contact Support.
Important: Fraudulent messages or calls impersonating BB4 may occur. BB4 will never ask for your password or OTP over the phone. If you receive anything suspicious, report it directly to support@bb4.im.
BB4's services are intended for users aged 18 and above. BB4 does not knowingly collect information from minors.
Date of birth is verified at registration. If a minor creates an account using false information and BB4 becomes aware of it, that account and all associated data will be deleted. If a parent or guardian suspects their child is using BB4, please contact support@bb4.im.
BB4 may update this Privacy Policy as needed. Any changes will be indicated by a revised date at the top of this page. For significant changes, registered users will be notified by email or push notification.
Continued use of BB4 after any changes takes effect will be considered acceptance of the updated policy. If you do not agree to the new policy, you may request that your account be closed.
For any questions or complaints about this privacy policy, contact BB4 via live chat or support@bb4.im. BB4 treats all privacy-related complaints with the utmost seriousness.
