• Mobile phone number used during account registration
• Email address for correspondence and notifications

• Pages visited, session duration, clicks, and navigation patterns within zk77.vin
• Geolocation data (country or city level) to ensure platform accessibility and compliance

How We Use Your Information

zk77 uses the personal data we collect solely for purposes that are directly connected to delivering and improving our platform services. We do not use your data for purposes beyond those described below without your explicit consent:

• Account creation, authentication, and identity verification (KYC compliance)
• Processing deposits and withdrawals via bKash, Nagad, Rocket, Upay, and other supported payment methods

Payment Data and Financial Information

All financial transactions on zk77 are processed by certified payment service providers. When you make a deposit or request a withdrawal, your payment information — including your bKash account number, Nagad wallet details, Rocket mobile banking number, or card information — is handled directly by those payment processors in accordance with their own security and privacy frameworks. zk77 does not store full card numbers or mobile banking PINs on our servers.

We retain records of transaction amounts, timestamps, and payment method types (e.g., bKash, Nagad) solely to support dispute resolution, fraud prevention, and regulatory reporting obligations. This financial transaction history is stored securely and accessed only by authorised zk77 personnel.

Cookies and Tracking Technologies

zk77 uses cookies and similar tracking technologies to improve your browsing experience, maintain your login session, and understand how visitors interact with our platform. Cookies are small text files stored on your device. They do not contain executable code and cannot access other files on your device.

Types of Cookies We Use

• Essential cookies — required for core platform functionality such as user authentication and session management. These cannot be disabled.
• Analytics cookies — help us understand visitor behaviour, page performance, and usage patterns so we can improve the platform for Bangladeshi players.
• Preference cookies — remember your in-platform settings such as language selection and display preferences to personalise your experience.

You can manage or disable non-essential cookies through your browser settings at any time. Please note that disabling certain cookies may affect some features of the zk77 platform.

Data Sharing and Disclosure

zk77 does not sell, trade, or rent your personal data to any third parties for marketing purposes. We may share certain information only under the following strictly limited circumstances:

• Payment service providers (bKash, Nagad, Rocket, Upay, Visa, Mastercard, Dutch-Bangla Bank, BRAC Bank) — solely to process transactions you initiate
• Identity verification and KYC service partners — to fulfil age verification and anti-money-laundering obligations
• Legal authorities and law enforcement agencies — when required by applicable law, court order, or government regulation
• Technical service providers (e.g., hosting, cybersecurity, analytics) — under strict data processing agreements that prohibit them from using your data for their own purposes

All third parties who receive data from zk77 are contractually bound to handle that data securely and only for the purpose for which it was shared. We do not permit them to use your data for independent profiling, advertising, or resale.

Data Retention

zk77 retains your personal data only for as long as it is necessary to fulfil the purposes outlined in this Privacy Policy, or as required by applicable legal and regulatory obligations. The retention periods we apply are as follows:

Active account data is retained for the lifetime of your account plus a minimum of five years to meet anti-money-laundering and financial record-keeping requirements. If you request account closure, we will begin the deletion process for data no longer required by law within 30 days of your verified request. Data retained for legal compliance purposes will be securely deleted once the statutory retention period expires.

Security of Your Data

Protecting the personal data you share with zk77 is a technical and organisational priority. We implement multiple layers of security controls including 256-bit SSL/TLS encryption for all data in transit, firewalled and access-controlled server environments, regular security audits and vulnerability assessments, and strict role-based access controls that limit employee access to only the data required to perform their job functions.

While we take every reasonable step to protect your data, no online platform can guarantee absolute security against all possible cyber threats. We encourage you to use a strong, unique password for your zk77 account, enable two-factor authentication where available, and never share your login credentials with anyone. If you suspect unauthorised access to your account, please contact our support team immediately.

• Right to Rectification — request correction of inaccurate or incomplete personal data
• Right to Erasure — request deletion of your personal data where it is no longer necessary for the purposes for which it was collected (subject to legal retention obligations)
• Right to Restriction — request that we limit how we process your data while a correction or objection request is being resolved
• Right to Object — object to the processing of your data for direct marketing or profiling purposes

We aim to respond to all verified privacy rights requests within 30 days. In some cases involving complex or high-volume requests, this period may be extended by up to an additional 60 days, in which case we will notify you of the extension and the reason.

zk77 integrates games and services from reputable third-party providers including Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, and Ezugi. These providers may collect limited technical data (such as game session identifiers) necessary to deliver their services.

We encourage you to review the privacy policies of major game providers if you have specificconcerns about their data practices.
