People in Bangladesh are becoming increasingly aware of what happens to their data online. "Where does my information go?" is a completely valid question, and 644bd believes every member has every right to ask it. That's why 644bd has always been committed to explaining data collection and usage clearly and transparently — in plain Bengali.
Every piece of information requested during registration on 644bd has a specific purpose. Your mobile number is required to send transaction confirmations and to support account recovery. Your date of birth is used to verify that you meet the 18+ age requirement. Your National ID is requested during KYC because confirming identity before processing payments is a mandatory condition of our international gaming license. No information is collected without a clear reason.
644bd secures your data using the same technology trusted by banks. With 256-bit SSL encryption, any information travelling between your browser and our servers is completely unreadable to third parties. Data stored on our servers is also encrypted — meaning even if someone gained direct database access, they could not read your password or payment details.
644bd enforces a strict access policy for its staff. A customer service representative can only view the information necessary to resolve a specific issue. Any access outside of authorized scope is logged and reviewed in regular audits. 644bd maintains a zero-tolerance policy against misuse of data.
Many members wonder about data sharing with payment gateways. When you deposit to 644bd via bKash, 644bd only informs bKash that a specific amount is being transferred from a given number to 644bd's wallet. Your gaming history, betting records, and national ID details are never shared with bKash. Only the minimum information required to process the payment is shared.
A question we hear often is: "Is my data used to show me ads?" The answer is no. 644bd does not sell your browsing data or gaming preferences to advertisers. Even showing you relevant offers on 644bd's own platform requires your consent. If you turn off marketing notifications in your account settings, 644bd will stop sending promotional messages entirely — only essential transactional notifications will still reach you.
There is a practical limitation regarding the right to deletion. Under 644bd's license conditions and Bangladesh's financial regulations, transaction records must be retained for 7 years. These specific records cannot be deleted upon account closure. However, personal contact details, marketing preferences, and device information are automatically deleted once their retention period expires.
644bd believes data privacy is not just a legal requirement — it is an ethical responsibility. Over 1.4 million members in Bangladesh have entrusted 644bd with their personal information, and protecting that trust matters more to us than any business outcome. For questions about this Privacy Policy or any data-related concerns, please reach out to privacy@644bd.best.
