77dk Privacy Policy
This policy explains what personal data 77dk collects from players in Bangladesh, why we collect it, how we protect it, and what rights you have over your information.
Section 1
Introduction and Scope
77dk ("we", "us", "the Platform") is committed to protecting the privacy and personal data of every individual who registers an account, visits the 77dk website at https://77dk.app, or otherwise interacts with our services. This Privacy Policy ("Policy") explains in clear, plain English how we collect, store, use and share personal data in connection with the operation of our online casino and sports betting platform.
By registering an account on 77dk or using any service provided through the platform, you acknowledge that you have read and understood this Policy and consent to the processing of your personal data as described herein. If you do not consent, please do not register an account or use the platform.
Section 2
What Personal Data We Collect
77dk collects only the personal data that is necessary for the purposes set out in this Policy. The categories of data we collect are listed below.
Registration Data
Full name, date of birth, Bangladeshi mobile number, email address and preferred username collected when you create your 77dk account. This data is used to identify your account and verify your age eligibility (21+).
Identity Verification (KYC) Data
Copies of government-issued identity documents such as your National Identity Card (NID) or passport, submitted during the KYC verification process. This is required before your first withdrawal can be processed.
Financial & Transaction Data
Mobile banking account references (bKash, Nagad or Rocket), deposit amounts, withdrawal requests, bet history and account balance history. Payment credentials such as full bKash PINs are never stored by 77dk — only the account reference number used to route transactions.
Technical & Device Data
IP address, device type, browser type and version, operating system, screen resolution and session timestamps. This data is collected automatically when you visit 77dk and is used for fraud prevention, security monitoring and platform performance optimisation.
Support & Communications Data
Records of your email correspondence with the 77dk support team, including the content of messages sent to [email protected], timestamps and issue resolution notes. This data is retained to ensure continuity of support and to maintain a record of responsible gaming interventions where applicable.
Section 3
How We Use Your Personal Data
77dk processes personal data only for the specific, documented purposes set out below. We do not process personal data for any purpose that is incompatible with those listed.
Account Management
To create and maintain your player account, authenticate your identity at login, manage your account settings, and deliver the full range of 77dk casino and sports betting services to you throughout your session.
Payment Processing
To process deposits and withdrawals through bKash, Nagad and Rocket, verify payment source references for anti-fraud purposes, and maintain an accurate transaction ledger for your account history and any withdrawal audits.
Fraud Prevention & Security
To detect, investigate and prevent fraudulent activity, money laundering, identity theft, and breaches of our Terms & Conditions. Technical data including IP addresses and device fingerprints is analysed by our automated security systems in real time.
Platform Improvement
Aggregated and anonymised technical data is used to analyse platform performance, identify pages with high load times, improve the mobile browsing experience for players in Dhaka, Chittagong and across Bangladesh, and prioritise feature development.
Service Communications
To send you transactional communications that are essential to your use of the platform — including deposit confirmations, withdrawal status updates, KYC verification requests and responsible gaming notifications. Marketing communications are only sent where you have provided explicit consent and may be opted out of at any time by contacting support.
Section 4
Legal Basis for Processing
77dk processes your personal data on the following legal bases, depending on the specific purpose for which the data is used.
- Contractual necessity — processing your registration data, KYC data and transaction data is required to create and fulfil our contractual relationship with you as a registered player on the 77dk platform.
- Legitimate interests — fraud prevention, security monitoring and platform analytics are conducted on the basis of our legitimate interest in operating a safe, reliable and compliant gaming platform.
- Consent — marketing communications and optional data uses (such as personalised promotions) are processed only where you have given explicit, freely given, informed consent that can be withdrawn at any time.
- Legal obligation — retention of transaction records and KYC documentation may be required by applicable laws governing financial services and anti-money laundering. 77dk will comply with any lawful data request from a competent authority.
Section 5
Data Sharing and Third Parties
77dk does not sell, rent or trade your personal data to third parties for commercial purposes. We share personal data only in the limited circumstances described below.
- Payment processing partners — bKash, Nagad and Rocket receive the account reference numbers and transaction amounts strictly necessary to route deposits and withdrawals. These partners operate under their own privacy frameworks and are not authorised to use your data for any other purpose.
- Game content providers — Pragmatic Play, Evolution Gaming, Spribe, Ezugi, NetEnt and Microgaming receive anonymised session tokens and game round data to render games in your browser. No personally identifiable information is transmitted to game studios.
- KYC and identity verification services — where a third-party verification service is used to cross-check NID documents, only the minimum data required for the verification check is transmitted over an encrypted connection.
- Competent authorities — 77dk will disclose personal data to law enforcement agencies, regulatory bodies or courts when required to do so by a lawful order, court order or applicable legal obligation. We will inform you of any such disclosure where we are legally permitted to do so.
Section 6
Cookies and Tracking Technologies
77dk uses cookies and similar local storage technologies to maintain your session, remember your preferences and support security functions. No third-party advertising cookies are placed on the 77dk platform. The categories of cookies we use are described below.
Essential Cookies
Required for the platform to function. These include your authentication token (keeping you logged in during a session), CSRF protection tokens, and language preference storage. These cannot be disabled without breaking core platform functionality.
Analytics Cookies
Used to collect anonymised data about how players navigate the 77dk platform — such as which pages are visited most frequently and where users encounter errors. This data is aggregated and cannot be used to identify you personally. Analytics help us improve the platform experience for players across Bangladesh.
Security Cookies
Short-lived tokens used to detect and block suspicious activity patterns, such as repeated failed login attempts or unusual transaction velocity. These are an integral part of our fraud prevention infrastructure and are renewed on each authenticated session.
You may manage cookie preferences through your mobile browser's built-in settings. Please note that disabling essential cookies will prevent you from logging in to your 77dk account. 77dk does not use any cross-site tracking, social media pixels, or third-party retargeting scripts.
Section 7
Data Security Measures
77dk implements layered technical and organisational security measures to protect your personal data against unauthorised access, loss, destruction or alteration. The key measures in place are described below.
SSL/TLS Encryption
All data transmitted between your device and the 77dk platform is encrypted using TLS 1.2 or higher. This ensures that login credentials, payment references and personal data cannot be intercepted in transit by third parties.
Password Hashing
Account passwords are never stored in readable form. 77dk uses industry-standard cryptographic hashing algorithms with per-account salting, meaning that even in the hypothetical event of a data breach, raw passwords would not be exposed.
Breach Response
In the event of a personal data breach that poses a risk to affected players, 77dk will take immediate steps to contain the breach, assess its scope, and notify affected account holders as soon as practicably possible. Breach records are maintained internally in accordance with our incident response procedures.
Section 8
Data Retention
77dk retains personal data only for as long as is necessary for the purpose for which it was collected, or as required by applicable legal obligations. Account data (registration details, KYC documents and transaction history) is retained for a minimum of five years from the date of account closure to satisfy anti-money laundering record-keeping requirements. After this retention period, data is securely deleted or irreversibly anonymised.
Support communications are retained for two years from the date of the last interaction. Analytics data in aggregated, anonymised form has no fixed retention period as it cannot be linked to any individual. Marketing consent records are retained for the duration of your account and for three years after account closure, to demonstrate compliance.
Section 9
Your Data Rights
As a player on the 77dk platform, you have the following rights in relation to your personal data. To exercise any of these rights, please contact us at [email protected]. We will respond to all verifiable requests within a reasonable timeframe.
- Right of access — you may request a copy of all personal data that 77dk holds about you, along with information about how it is being used and with whom it has been shared.
- Right to rectification — if any personal data held about you is inaccurate or incomplete, you may request that it be corrected or updated.
- Right to erasure — you may request deletion of your personal data where it is no longer necessary for the purposes for which it was collected, subject to any overriding legal retention obligations.
- Right to restriction — you may request that 77dk restrict processing of your personal data in certain circumstances, for example while a rectification request is being assessed.
- Right to data portability — where processing is based on your consent or on a contract, you may request that your personal data be provided to you in a structured, commonly used, machine-readable format.
- Right to withdraw consent — where processing is based on consent, you may withdraw that consent at any time. Withdrawal does not affect the lawfulness of processing carried out before withdrawal.
77dk will not charge a fee for responding to data rights requests unless a request is manifestly unfounded or excessive. In such cases, we may charge a reasonable administrative fee or decline to act on the request, with written reasons provided.
Section 10
Children and Minors
The 77dk platform is strictly intended for individuals who are 21 years of age or older. 77dk does not knowingly collect personal data from any person under the age of 21. If we become aware that personal data has been collected from an individual who is under 21, we will take immediate steps to delete that data and close the associated account.
Section 11
Changes to This Privacy Policy
77dk reserves the right to update or revise this Privacy Policy at any time to reflect changes in our data processing practices, applicable law, or platform functionality. When material changes are made, the revised Policy will be published on this page with an updated "Last updated" date. Where practicable, registered players will be notified by the contact details associated with their account.
Your continued use of the 77dk platform after any revision to this Policy is published constitutes your acceptance of the updated terms. We encourage you to review this page periodically to stay informed of how 77dk protects your personal data.
Section 12
