678d believes your personal data belongs entirely to you. This page clearly explains — in Bengali — what information we hold, why we hold it, and how we keep it secure.
By using 678d's services, you agree to this Privacy Policy. If any significant changes are made, you will be notified in advance. For any questions, feel free to reach out to our Bengali support team.
From the moment you create an account on 678d to your everyday use, certain information is collected. Without this data, we simply cannot provide our services properly — so we're being upfront about exactly what is stored.
The information you provide when opening an account forms the basis of your identity on 678d. This includes:
Identity verification is required to process withdrawals. For this purpose, 678d collects a copy of your National ID (NID) or other valid identity document. These documents are used solely for KYC verification and are stored securely.
While you use 678d, certain information is collected automatically — this is necessary to keep the platform secure and running smoothly:
When you contact 678d via live chat or email support, those conversations are recorded. This helps us improve service quality over time and prevents the same issues from recurring.
Any information collected by 678d is used strictly for its intended purpose. No data is processed unnecessarily.
Your data is used to create and manage accounts, process payments, and determine betting and game outcomes — core functions that 678d cannot deliver without it.
Age verification is mandatory for every user under international gaming regulations. No one under 18 can open an account or place bets on 678d. Date of birth and identity documents are used to confirm this.
Detecting multiple accounts, preventing bonus abuse, and monitoring suspicious transactions — collected data plays a key role in all of these. It is done to protect honest players.
Data helps 678d understand which features get the most use, where issues arise, and which payment methods are most popular — enabling continuous improvement of the platform.
Certain data must be retained to meet the requirements of licensing authorities and legal bodies. 678d does not use any information beyond what is required by law for any other purpose.
| Data Type | Purpose of Use | Legal Basis |
|---|---|---|
| Full name and date of birth. | Identity & Age Verification | Legal Obligations |
| Mobile Number | OTP, Support | Contractual Necessity |
| Payment Information | Transaction Processing | Contractual Necessity |
| IP & Device Information | Security | Legitimate Interest |
| Gaming History | Account Management | Contractual Necessity |
678d uses multiple layers of security to keep your data safe. These aren't just policies on paper — they're actively working every day.
All communication between you and the 678d website and app is encrypted using TLS 1.3 — the most current and secure encryption standard available. No one can intercept or read your data in transit.
678d offers the option to enable two-factor authentication. When active, a password alone is not enough to log in — an OTP sent to your mobile is also required. Enabling this feature significantly strengthens your account security.
All data stored on 678d's servers is encrypted. Passwords are never stored in plain text — only in hashed form. This means even 678d's own staff cannot view your password.
Third-party cybersecurity experts regularly audit 678d's systems. Any vulnerabilities found are addressed immediately.
If unusual activity is detected on your account, 678d automatically issues a security alert and, if necessary, temporarily locks the account and notifies you. This is entirely for your protection.
678d's website and app use cookies. Cookies are small files stored in your browser that help improve your experience on the site.
These cookies are essential for the site to function properly. They are required to maintain login sessions, perform security checks, and keep core features running. These cookies cannot be disabled.
Performance cookies collect data on page load speeds and errors. No personal information is involved — only technical statistics.
Functionality cookies remember your preferences — such as language settings and interface choices. Disabling them means you will need to reconfigure your settings each time you log in.
You can manage cookies directly from your browser settings. All non-essential cookies can be disabled. Keep in mind that turning off certain cookies may limit some features.
678d does not retain data beyond what is necessary. Every category of information has a defined retention period.
While your account is active, your registration details, transaction history, and gaming activity are stored. This is necessary for account management and service delivery.
Even after account closure, certain data must be retained for a defined period due to legal obligations. Under international gaming licence conditions, transaction and KYC records are typically required to be kept for up to 5 years.
Once the defined retention period expires, data is securely deleted or fully anonymised. This process is automated and runs on a regular schedule.
As a 678d user, you have important rights over your personal data. To exercise any of these rights, contact the 678d support team in Bangla.
You have the right to know what information 678d holds about you. Submit a request to Support and you will receive a full data summary within 30 days.
If any information in your account is incorrect, you can request a correction. Errors in your name or address can be updated by submitting the relevant KYC documents.
After closing your account, you may request deletion of data that is not subject to legal retention requirements. Any data that must be retained by law cannot be deleted, but you will be clearly informed of this.
In certain cases, you can request to limit how your data is being used — for example, opting out of marketing communications.
For any questions, complaints, or requests regarding this Privacy Policy, contact the 678d support team directly. Ask in Bangla — and you'll get a response in Bangla.
Any updates to 678d's Privacy Policy will be reflected on this page, and registered users will be notified via mobile notification.
For any significant changes to the Privacy Policy, 678d will send a notification at least 14 days in advance. Minor editorial changes will be indicated by updating the revision date.
The six pillars that uphold 678d's data protection framework
TLS 1.3 encryption ensures your data cannot be read by anyone during transfer. 678d follows the same security standard used in the banking industry.
678d never sells your personal data to advertisers or third parties. This is not just a statement — it is contractually prohibited.
This Privacy Policy is written in Bengali so every user can clearly understand what is happening — no fine print traps, no complex legal jargon.
External experts regularly audit 678d's systems. Any vulnerabilities discovered are acted on immediately — before you even need to be informed.
You can request to view, correct, or delete your data at any time. 678d will process such requests within 30 days.
Ask any data protection question in Bangla — the 678d support team is ready to provide a detailed response.

No — you must be at least 18 years old to open an account or participate in any betting activity on 678d. This is not just an internal policy; it is a requirement under our international gaming licence and is strictly enforced at all times.
Your date of birth is collected at registration and subsequently confirmed through your National ID during KYC verification. If the details do not match, the account will be terminated and any existing balance may not be refunded.
678d is committed to responsible gaming — and protecting minors is a core part of that. If you suspect an underage person is using an account, contact support and 678d will take immediate action.
678d supports Bangladesh's three leading mobile banking services — bKash, Nagad, and Rocket. All three can be used for both deposits and withdrawals.
BKash is the most widely used method — around 58% of all 678d transactions go through bKash. Nagad ranks second, followed by Rocket. All three support a minimum deposit of ৳200, with withdrawals starting from ৳500.
Deposits typically arrive in your 678d wallet within seconds. Withdrawals are processed within 30 minutes to a maximum of 4 hours — provided KYC has already been completed. One important thing to note: withdrawals will only be sent to the same mobile number used for the deposit.
