4 How We Collect Your Data
dk77 collects personal data through the following channels and methods:
4.1 Directly From You
The majority of personal data we hold is provided directly by you during the registration process, KYC verification, payment transactions, customer support interactions, or when you update your account profile settings.
4.2 Automatically Through Platform Use
When you access dk77, our servers automatically collect technical and device data including your IP address, browser type, device identifiers, and session activity data. This collection occurs through server logs, session cookies, and analytics technologies embedded in the Platform.
4.3 From Payment Service Providers
When you make a deposit or request a withdrawal, our integrated payment service providers — including bKash, Nagad, Rocket, Upay, and partner Bangladeshi banks — transmit transaction confirmation data to dk77, including your registered mobile number or bank account reference, the transaction amount, and the transaction reference number. dk77 does not store full payment credentials; only the reference data necessary to reconcile your account balance is retained.

Game studios whose products are accessible via dk77 — including Evolution Gaming, Pragmatic Play, Microgaming, NetEnt, Ezugi, and Spribe — may transmit game session identifiers and round results data to dk77 for the purposes of account settlement, dispute resolution, and responsible gaming monitoring. No additional personal data beyond what is already held by dk77 is shared by these providers.

Where automated KYC verification tools are used, an authorised third-party identity verification provider may process the identity documents you submit in order to confirm their authenticity.

7.3 Game Technology Providers
Game studios (such as Evolution Gaming, Pragmatic Play, Microgaming, NetEnt, Ezugi, and Spribe) receive session and game-round identifiers necessary to deliver and settle game outcomes.

7.4 Legal and Regulatory Disclosure
dk77 may disclose personal data to competent authorities, courts, or regulators where required to do so by applicable law, court order, or lawful regulatory demand.

In the event of a merger, acquisition, or sale of substantially all of dk77's assets, personal data held by dk77 may be transferred to the acquiring entity as part of the transaction. In such circumstances, the acquiring entity will be required to honour the privacy commitments set out in this Policy, and Players will be notified of any material change in data controller identity.

10 Data Security
dk77 implements a comprehensive set of technical and organisational security measures designed to protect your personal data against unauthorised access, accidental loss, destruction, alteration, or disclosure. These measures include:
- 256-Bit SSL/TLS Encryption: All data transmitted between your device and dk77's servers is encrypted in transit using TLS 1.2 or higher, preventing interception of your account credentials, payment details, and personal information.
- Encrypted Data Storage: Sensitive personal data fields — including identity document references, payment method identifiers, and KYC records — are encrypted at rest in dk77's database infrastructure.
- Password Hashing: Account passwords are never stored in plain text. dk77 uses a one-way cryptographic hashing algorithm with salting to store password credentials, meaning that even dk77's internal team cannot retrieve your password.
- Access Controls: Access to personal data within dk77's internal systems is restricted on a strict need-to-know basis. All staff with data access are subject to confidentiality obligations and regular security training.
- Fraud Detection Systems: Automated systems monitor all Platform activity for signs of unauthorised access, credential stuffing attacks, multi-accounting, and payment fraud in real time.
- Regular Security Audits: dk77 conducts periodic internal security reviews and works with external security specialists to identify and remediate vulnerabilities in its Platform infrastructure.

12 Third-Party Links
The dk77 Platform may, from time to time, contain references to or integrations with third-party game providers and payment processors. These third-party services have their own independent privacy policies, and dk77 does not accept any responsibility or liability for the privacy practices of those third parties. We recommend that you review the privacy policy of any third-party service you interact with through or alongside the dk77 Platform.
dk77 does not embed third-party advertising networks, social media tracking pixels, or external analytics platforms that would share your personal data with unrelated third parties without your knowledge.
13 Children's Privacy and the 21+ Requirement
The dk77 Platform is strictly for adults aged 21 years and above. dk77 does not knowingly collect, store, or process personal data belonging to individuals under the age of 21. If we become aware that a person under 21 has registered an account or submitted personal data through the Platform, we will immediately suspend the account, delete all associated personal data, and — where a deposit has been made — return the funds to the original payment method.
If you believe that a person under the age of 21 has accessed or registered on dk77, please notify us immediately at [email protected] so that we may take prompt action. dk77 cooperates fully with parental control software providers and supports the use of filtering tools by parents and guardians concerned about underage access to online gambling platforms.
14 Updates to This Privacy Policy
dk77 reserves the right to amend or update this Privacy Policy at any time to reflect changes in our data processing practices, applicable legal requirements, or the features and services available on the Platform.
