At 400gm, your personal information matters to us deeply. We are fully committed to protecting the privacy of users in Bangladesh.

Last Updated: January 2026
Why This Policy Applies
400gm is a trusted online gaming and betting platform in Bangladesh, fully committed to providing its users with the highest level of security and privacy. This privacy policy has been developed in accordance with applicable Bangladeshi law and international standards. It applies to anyone who visits our website or creates an account. We believe transparency is the foundation of trust, which is why every aspect of how we handle your data is clearly explained here. You retain full control over your personal information and may request corrections or deletion at any time.
This privacy policy is connected to our Terms and Conditions and Responsible Gaming policy. We commit that your information will never be sold or used without authorization. Should this policy be updated, a notice will be posted on the platform and the revision date will be updated accordingly.
Personal & Technical Data
When you register on the 400gm platform, we collect your name, email address, date of birth, and Bangladeshi mobile number. Identity verification may require your National ID or passport details, which are stored under strict security measures. Financial transaction information — such as bKash, Nagad, or other payment details — is collected to process transactions; however, full card or account numbers are never stored. Your gaming history, betting activity, and time spent on the platform are used to improve our services. Your device's IP address, browser type, and operating system are also collected automatically to ensure platform security.
Purpose & Scope of Data Use
The information we collect is primarily used to manage your account, deliver our services, and process transactions. We analyze your gaming activity to create a personalized experience that makes your time on the platform more enjoyable. Your data is also used to prevent fraud, comply with anti-money laundering regulations, and meet the requirements of Bangladeshi regulatory authorities. Where necessary, your information may be securely shared with our support team to improve customer service and resolve technical issues. With your consent, we may send you emails or SMS messages to keep you updated on our products and services.
We never sell your information to advertisers or third parties. Data may only be disclosed to Bangladeshi government authorities where legally required. You can opt out of our marketing communications at any time.
Cookie Use & Controls
400gm uses cookies to keep the website running smoothly. These are small text files stored in your browser. Essential cookies are required to maintain login sessions and ensure security — without them, the site cannot function properly. Analytical cookies help us understand how users interact with the platform, allowing us to improve the quality of our services. Preference cookies remember your language selection, theme, and other personal settings, so you don't have to reconfigure them every time you log in. You can manage or delete cookies at any time through your browser settings, though doing so may limit certain features.
How Your Data Is Protected
400gm uses industry-leading technology to keep your data secure. All communication between your browser and our servers is fully encrypted via SSL/TLS. Sensitive data stored in our databases is protected with AES-256 encryption, which is virtually impossible to break with current technology. Our servers are housed in secure data centers with physical and digital security maintained around the clock. Regular security audits and penetration testing allow us to identify and address potential vulnerabilities proactively.
Our platform supports Two-Factor Authentication (2FA), giving you an extra layer of security on your account. If unusual login attempts or suspicious activity are detected, we automatically secure your account and send you an alert. Our security team monitors the platform around the clock to ensure any threats are addressed promptly.
When and With Whom Information Is Shared
400gm never sells or transfers your personal information to third parties for commercial purposes. In certain limited circumstances, we may need to share specific data — always in the interest of protecting you. Only the information necessary to complete a transaction is shared with payment processors such as bKash, Nagad, or other approved payment gateways. We may be required to disclose information to government authorities to comply with Bangladeshi legal requirements or by court order. Relevant data may also be exchanged with regulatory bodies in connection with fraud investigations or anti-money laundering efforts. Our technology partners operate under strict confidentiality agreements and are prohibited from using your data for their own purposes.
Your Control Over Your Data
Every 400gm user has full rights over their personal data. You may request a complete copy of the information we hold about you at any time, and we are obligated to provide it within 30 business days. If any of your personal details are incorrect, you can request a correction and we will verify and update them promptly. Under certain circumstances, after closing your account, you may request deletion of your data — though some information may need to be retained for a specified period due to legal obligations. You can opt out of our marketing communications at any time and object to how your data is processed. To exercise any of these rights, please contact our support team.

How Long We Retain Your Data
We retain your personal information only for as long as it is necessary or legally required. For active accounts, your data is kept for the duration the account remains open. After an account is closed, financial transaction records may be retained for up to 5 years in accordance with Bangladeshi law. Identity verification documents must be retained for a specified period under Anti-Money Laundering (AML) regulations — this is a legal obligation. Once the applicable retention period expires, your data is permanently and securely deleted to prevent any future misuse. Data held for marketing purposes is deleted immediately upon withdrawal of your consent.

Strictly prohibited for users under 18
400gm is a platform strictly operated for individuals aged 18 and above. Protecting minors is one of our highest priorities and we make no compromises on this. A rigorous age verification process is applied at registration, and identity documents may be requested in any case of doubt. If it is found that a minor has opened an account, that account will be immediately closed and all associated data will be deleted. We urge parents to monitor their children's online activity and to contact us if they notice any concerns. Responsible gaming is a core part of our values.

400gm may periodically update this privacy policy to reflect business needs or changes in applicable law. We will notify you of any significant changes via email or an in-platform notification before they take effect. If you continue using the platform after an update, you will be considered to have accepted the revised policy. We recommend visiting this page regularly to stay informed.
