• Automated collection: Technical and usage data collected automatically by our servers and analytics systems each time you access the platform, including via server logs, session tracking, and first-party cookies.
• Payment providers: Transaction confirmation data (reference numbers, amounts, timestamps) received from bKash, Nagad, Rocket, and Upay when you initiate a deposit or withdrawal.
• Game providers: Game session data (rounds played, results, stake amounts, RTP outcomes) received from Evolution Gaming, Ezugi, Pragmatic Play, NetEnt, Microgaming, Spribe, and other certified game supplier partners to enable bet settlement and dispute resolution.
• Fraud and compliance screening: In some cases, identity and age verification data may be cross-checked against third-party identity verification services for KYC compliance purposes.

4 Purposes of Processing

577b processes personal data for the following specific, documented purposes:

• Account creation and management: To register your 577b account, verify your identity, maintain your account profile, and enable access to platform services.
• Payment processing: To facilitate BDT deposits and withdrawals via your chosen mobile financial service (bKash, Nagad, Rocket, or Upay) and to maintain accurate financial records.
• Age and identity verification (KYC): To confirm that all players on the platform are aged 21 or above and that account details match the registered payment source, in accordance with responsible gaming obligations.
• Bet settlement and gaming: To record bets placed, settle outcomes, calculate winnings, apply bonus wagering requirements, and maintain a complete account transaction history.
• Fraud prevention and security: To detect, investigate, and prevent fraudulent activity, multi-accounting, chargebacks, money laundering, and other prohibited conduct as described in our Terms & Conditions.
• Customer support: To respond to your enquiries, resolve disputes, and provide technical assistance via live chat, email, and WhatsApp.
• Platform improvement: To analyse usage patterns, identify technical issues, and improve the performance, layout, and content of the 577b platform for the benefit of all players.

• Legal and regulatory compliance: To meet obligations under applicable financial, anti-money laundering, and data protection laws, and to respond to lawful requests from regulatory or law enforcement authorities.

5 Legal Basis for Processing

577b processes your personal data on one or more of the following legal bases, depending on the specific processing activity:

• Contractual necessity: Processing required to fulfil the contract between you and 577b — specifically, to operate your account, process transactions, and deliver the gaming and betting services you have requested.
• Legal obligation: Processing required to comply with applicable laws and regulations, including age verification, anti-money laundering (AML) procedures, and financial record-keeping requirements.
• Legitimate interests: Processing carried out in pursuit of the legitimate interests of 577b, including fraud prevention, platform security, abuse detection, and service improvement, provided such interests are not overridden by your fundamental rights and freedoms.
• Consent: Processing based on your freely given, specific, and informed consent — primarily in the context of marketing communications and optional analytics features. You may withdraw consent at any time without affecting the lawfulness of prior processing.

6 Cookies & Tracking

The 577b platform uses cookies and similar tracking technologies to deliver a functional, secure, and personalised experience. The following categories of cookies are in use:

• Strictly necessary cookies: Required for the platform to function correctly. These include session authentication tokens, security cookies, and load-balancing cookies. These cookies cannot be disabled without preventing core platform functionality.
• Performance cookies: Used to collect anonymised data about how players use the platform — including which pages are visited most frequently and where errors occur — enabling us to improve platform performance. No personally identifiable information is collected via these cookies.
• Functional cookies: Store your preferences such as language settings, preferred game lobby view, and account display options, so they are remembered across sessions.
• Analytics cookies: First-party analytics tools use cookies to measure session durations, click paths, and feature engagement. This data is used in aggregate form for product development decisions.

7 Third-Party Data Sharing

577b does not sell, rent, or trade your personal data. Data is shared with third parties only in the following limited and documented circumstances:

• Payment processors: bKash, Nagad, Rocket, and Upay receive the minimum data required to process your deposit or withdrawal transaction (account number, amount, reference). These providers operate under their own privacy policies and are independently regulated.
• Game providers: Evolution Gaming, Ezugi, Pragmatic Play, NetEnt, Microgaming, Spribe, and other certified game supplier partners receive a pseudonymous player identifier and stake/session data necessary to operate game software and settle outcomes. They do not receive your full identity or payment details.
• Identity verification services: Where KYC verification is required, identity data (name, date of birth, document number) may be shared with a certified third-party identity verification provider for the sole purpose of completing the verification check.
• Legal and regulatory authorities: 577b will disclose personal data to law enforcement, financial intelligence units, or regulatory bodies where required to do so by a lawful order, court direction, or applicable legal obligation. 577b will notify the affected player of any such disclosure where legally permitted to do so.
• Corporate transactions: In the event of a merger, acquisition, or sale of all or part of the 577b business, player data may be transferred to the acquiring entity, subject to equivalent privacy protections and advance notice to affected players.

All third-party data processors engaged by 577b are required to enter into a data processing agreement that imposes binding obligations regarding the confidentiality, security, and permitted use of the personal data they handle.

8 International Data Transfers

The 577b platform primarily serves players in Bangladesh, and personal data is ordinarily processed within infrastructure serving the South and Southeast Asian region. However, some of our third-party game provider and technology partners operate infrastructure in other jurisdictions.

Where personal data is transferred outside Bangladesh to a jurisdiction that may not offer an equivalent level of data protection, 577b takes the following protective measures:

• Data processing agreements incorporating standard contractual clauses that impose binding data protection obligations on the recipient.
• Technical safeguards including end-to-end encryption of data in transit and at rest.
• Minimum-data-transfer principles — only the specific data elements necessary for the defined processing purpose are transferred, with no bulk or speculative data exports.

9 Data Retention

577b retains personal data only for as long as is necessary to fulfil the purpose for which it was collected, or as required by applicable legal and regulatory obligations. The following indicative retention periods apply:

Upon expiry of the applicable retention period, personal data is securely deleted from active systems and purged from backups within the standard backup rotation cycle. Where data cannot be fully deleted due to technical constraints, it is anonymised so that it can no longer be linked to any identifiable individual.

10 Your Data Rights

As a player on the 577b platform, you hold the following rights with respect to your personal data. Requests to exercise any of these rights should be submitted to [email protected], clearly stating which right you wish to exercise and providing sufficient information to verify your identity.

11 Data Security

577b implements a layered security architecture to protect personal data against unauthorised access, disclosure, alteration, and destruction. Key security measures in place include:

• Transport encryption: All data transmitted between your browser or mobile device and 577b servers is encrypted using TLS 1.2 or higher. The platform enforces HTTPS on all endpoints.
• Data-at-rest encryption: Sensitive data fields stored in our databases — including identity document references and financial account details — are encrypted at the application layer in addition to database-level encryption.
• Access controls: Access to personal data is restricted to 577b staff members and authorised processors who require it to perform their specific job function. Role-based access controls and audit logging are enforced across all internal systems.
• Two-factor authentication: Internal systems containing personal data require two-factor authentication for all staff access. Players are encouraged to enable 2FA via OTP on their own accounts.
• Penetration testing and security audits: The 577b platform infrastructure undergoes regular security assessments to identify and remediate vulnerabilities before they can be exploited.
• Incident response: In the event of a data breach that creates a risk to player rights or freedoms, 577b will notify affected players without undue delay and will take immediate remediation action. A breach log is maintained for all security incidents regardless of severity.

While 577b takes all reasonable measures to protect your data, no internet-based platform can guarantee absolute security. You are responsible for keeping your own 577b Login credentials confidential and for using a secure, private device when accessing your account.

12 Children & Minors

The 577b platform is strictly restricted to individuals aged 21 years or older. 577b does not knowingly collect personal data from any person under the age of 21. The platform's registration process includes age declaration and identity verification steps specifically designed to prevent underage access.

If 577b becomes aware that personal data has been collected from an individual under the age of 21, the relevant account will be immediately suspended, the personal data deleted, and any real money balance returned to the verified payment source. If you believe a minor has accessed the 577b platform, please notify us immediately at [email protected] so that we can take prompt action.

13 Marketing Communications

577b may send promotional communications to registered players covering bonus offers, seasonal promotions (such as those tied to BPL, IPL, T20 World Cup, Eid, Pohela Boishakh, and Victory Day), new game launches, and platform updates. Marketing communications are sent only to players who have opted in to receive them at the time of registration or subsequently through their account settings.

You may opt out of marketing communications at any time by:

• Using the unsubscribe link included in every marketing email sent by 577b.
• Updating your communication preferences in the notifications section of your 577b account dashboard.
• Contacting 577b support directly at [email protected] with a clear opt-out request. Opt-out requests submitted by email are processed within 5 business days.

Opting out of marketing communications does not affect transactional communications — such as deposit confirmations, withdrawal notifications, account security alerts, and KYC verification requests — which are sent regardless of marketing preferences as they are necessary for the operation of your account.

14 Changes to This Policy

577b reserves the right to update this Privacy Policy at any time to reflect changes in our data practices, legal obligations, or platform functionality. Where changes are material — meaning they affect the categories of data collected, the purposes for which data is used, or the rights available to players — 577b will notify registered players via the email address on file no fewer than seven (7) days before the updated policy takes effect.

Minor updates such as typographical corrections, clarifications of existing practices, or contact information changes may be applied without prior notice. The effective date shown at the top of this page and in the footer will always reflect the most recent version. Your continued use of the 577b platform after the effective date of any updated policy constitutes your acknowledgement of the revised terms.

Previous versions of this Privacy Policy are archived and available upon request by contacting [email protected]. 577b will not make retroactive changes that reduce your data rights without explicit consent.
