Last Updated: January 2026
Introduction
477b ("477b", "We", "Us", "Our") operates the online casino and sports betting platform accessible at 477b.bio. We are committed to handling your personal data responsibly, transparently, and in accordance with applicable data protection principles. This Privacy Policy applies to all users of the 477b platform, including visitors who browse without registering and registered players who deposit, wager, and withdraw funds.
By registering an account on 477b or continuing to use the platform after this Privacy Policy has been published or updated, you acknowledge that you have read and understood this policy. If you do not agree with any aspect of this Privacy Policy, you should stop using the 477b platform and, if you have a registered account, close it by contacting our support team.
Privacy at a Glance
477b collects personal data from you in several ways: directly when you provide it (such as during registration or KYC), automatically as you use the platform, and in some cases from third-party payment processors. The categories of data we collect include:
- Identity and contact information: full name, date of birth, Bangladesh mobile number, and email address provided at registration.
- KYC verification documents: government-issued photo identification (such as a National ID card or passport) and proof of address or payment method ownership, collected when identity verification is required.
- Financial transaction data: deposit amounts, withdrawal requests, payment method identifiers (such as bKash or Nagad wallet numbers), and transaction timestamps. Full payment credentials are not stored by 477b — these are handled directly by the payment processor.
- Gaming and betting activity: bet history, game sessions played, wager amounts, wins and losses, bonus usage, and responsible gaming tool settings (such as deposit limits or self-exclusion status).
- Technical and device data: IP address, device type and operating system, browser type and version, screen resolution, and platform session logs. This data is collected automatically via server logs and cookies.
477b uses the personal data we collect for the following purposes:
- Account management: to create, maintain, and administer your 477b player account, including processing deposits and withdrawals, applying bonuses, and enabling responsible gaming tools.
- Identity verification and fraud prevention: to verify your identity in compliance with KYC obligations, detect suspicious account activity, prevent fraud, and protect against money laundering.
- Customer support: to respond to your queries, complaints, and requests submitted to the 477b support team, and to maintain a record of communications for quality assurance.
- Responsible gaming: to monitor your gambling activity for signs of problem gambling, apply self-imposed limits you have set, and contact you if we identify behaviour that may indicate gambling-related harm.
- Platform improvement and analytics: to analyse how players use the 477b platform, identify technical issues, improve game selection and user experience, and develop new features relevant to Bangladesh players.
- Marketing communications: to send you promotional offers, bonus notifications, and seasonal promotions (such as Eid or Pohela Boishakh offers) where you have not opted out of receiving such communications. You may opt out at any time by contacting 477b support.
477b processes your personal data on the following legal grounds:
- Contractual necessity: processing your identity data, financial transaction data, and account activity data is necessary for 477b to perform its contractual obligations to you as a registered player, including providing access to games and processing payments.
- Legal obligation: processing data for KYC verification, anti-money-laundering checks, responsible gaming compliance, and fraud detection is required to comply with applicable legal and regulatory obligations.
- Legitimate interests: processing technical and device data, platform analytics, and usage data is in 477b's legitimate interests to operate and improve a secure, reliable platform for Bangladesh players.
- Consent: where 477b sends you marketing communications, this is based on your consent (or your failure to opt out where a lawful opt-out mechanism has been provided). You may withdraw consent at any time.
477b does not sell your personal data to any third party. We may share your data with the following categories of recipients strictly as necessary for the purposes described in this policy:
- Payment processors: bKash, Nagad, Rocket, Upay, and our banking partners receive the transaction data necessary to process your deposits and withdrawals. These partners are bound by their own privacy obligations and do not receive data beyond what is needed for payment processing.
- Game providers: game software providers such as Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, and Spribe receive session and bet data in order to operate their games on the 477b platform. This data is governed by those providers' own data agreements with 477b.
- Identity verification and fraud prevention services: third-party KYC and anti-fraud service providers may receive identity documents and related data solely for the purpose of conducting verification checks required by 477b.
- Law enforcement and regulatory authorities: 477b may disclose personal data to law enforcement agencies or regulatory authorities where required to do so by law, court order, or where 477b reasonably believes that disclosure is necessary to prevent or report a crime or comply with a legal obligation.
477b takes the security of your personal data seriously. We implement a range of technical and organisational measures to protect your data against unauthorised access, loss, disclosure, or destruction. These include SSL encryption for all data in transit between your device and our servers, secure server infrastructure with access controls, regular security assessments, and staff training on data protection practices.
While 477b takes all reasonable steps to protect your personal data, no online platform can guarantee absolute security. You are also responsible for protecting your own account by using a strong, unique password and not sharing your login credentials with anyone. If you suspect your account has been compromised, please contact 477b support immediately.
As a user of the 477b platform, you have the following rights in relation to your personal data:
- Right of access: you may request a copy of the personal data that 477b holds about you. We will provide this within a reasonable timeframe following identity verification.
- Right of rectification: if any personal data we hold about you is inaccurate or incomplete, you have the right to request that we correct or update it. You may also update certain information directly within your account settings.
- Right of erasure: in certain circumstances, you may request that we delete your personal data. This right is subject to any overriding legal obligations that require 477b to retain your data (such as financial record-keeping requirements).
- Right to object to marketing: you may opt out of receiving marketing communications from 477b at any time by contacting our support team. Opting out of marketing does not affect service communications related to your account.
- Right to data portability: where technically feasible and where processing is based on your consent or a contract, you may request that your personal data be provided to you in a structured, commonly used, machine-readable format.
To exercise any of these rights, please contact 477b customer support at [email protected]. We will respond to all data rights requests within a reasonable timeframe and will ask you to verify your identity before processing your request.
477b uses cookies and similar tracking technologies on the platform. Cookies are small text files stored on your device that help the platform function correctly and allow us to understand how users interact with our service. The types of cookies we use include:
- Essential cookies: required for the platform to function. These include session authentication cookies that keep you logged in, security cookies that protect against cross-site request forgery, and cookies that remember your language and display preferences. These cannot be disabled without breaking core platform functionality.
- Analytical cookies: used to collect aggregated, anonymised data about how players use the platform, which pages are visited most frequently, and where errors occur. This data helps 477b improve platform performance and the player experience.
- Functional cookies: used to remember preferences you have set, such as responsible gaming limit reminders or notification preferences, so you do not need to re-enter these settings on each visit.
You can manage or disable non-essential cookies through your browser settings. Please note that disabling certain cookies may affect the functionality of some parts of the 477b platform. Your browser's help documentation will explain how to manage cookie settings for your specific browser.
