7 Data Sharing & Third Parties

tk3777 does not sell or rent your personal data to any third party. We may share limited personal data with the following categories of trusted service providers, strictly for the purposes described below:

• Payment Processors: bKash, Nagad, Rocket, Upay, Dutch-Bangla Bank, and card network processors receive only the minimum transaction data necessary to process deposits and withdrawals on your behalf;

• Game Providers: Game providers such as Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Ezugi, and Spribe may receive a pseudonymous player identifier to facilitate game session management. No directly identifiable personal data (such as your name or NID number) is shared with game providers;
• IT Infrastructure & Hosting Providers: Our platform infrastructure providers process data on our behalf under contractual data processing agreements that require them to maintain confidentiality and security standards equivalent to our own;
• Legal & Regulatory Authorities: We may disclose personal data to law enforcement, regulatory bodies, or courts when required to do so by applicable law, court order, or legal process.

All third-party service providers with whom tk3777 shares personal data are bound by contractual obligations to process that data only for the specified purpose and to maintain appropriate security standards.

8 International Data Transfers

The tk3777 Platform serves Bangladesh players, and our primary data processing infrastructure is located in data centres accessible from Bangladesh Standard Time (BST, UTC+6). In some instances, data may be processed by third-party service providers — such as game providers or cloud infrastructure partners — whose servers are located in other countries.

Where personal data is transferred outside Bangladesh, tk3777 ensures that appropriate safeguards are in place, including contractual data transfer agreements that impose data protection standards equivalent to those described in this Policy. We do not transfer personal data to jurisdictions that do not provide adequate protections for the rights described in this Policy.

Upon expiry of the applicable retention period, personal data is securely deleted or irreversibly anonymised in accordance with our data destruction procedures.
