Introduction: 678d's Commitment to Privacy

When signing up on any online platform, a natural question comes to mind — "Where is my name, mobile number, and payment information going?" That question is entirely valid, and 678d Believes every user deserves a clear answer to this question.

In this Privacy Policy, 678d explains: what data is collected, why it is collected, how long it is retained, who it is shared with, and how you can stay in control of your own information. Everything is written in plain English — no complex legal jargon.

Creating an account with 678d means you agree to this policy. That said, we strongly encourage you to read it in full before agreeing — because an informed member is what makes 678d stronger.

Important: 678d never sells your data. Information is only shared with third parties for payment processing and legal compliance — never for advertising purposes.

1. What information is collected

Data Collection Details

678d only collects information that is genuinely necessary to provide its services. No unnecessary data is ever requested.

Information collected at registration

  • Full Name (as per National ID)
  • Mobile Number
  • Date of Birth (for age verification)
  • Email Address (optional, but recommended)
  • Password (stored in encrypted form — we never have access to your actual password)

Information Collected During KYC Verification

  • National ID card photo (front and back)
  • Selfie holding your ID document
  • Source of Income Information for Large Transactions

Automatically collected information

  • IP address & device information (phone model, operating system)
  • Browser type and version
  • When you visited 678d, for how long, and which pages you accessed
  • Cookie & Session Data (details below)

Payment Information

678d does not store your bKash or Nagad PIN or bank account number directly. Payments are processed securely through the payment gateway, and only the transaction reference number and amount are recorded.

Please Note: 678d will never ask for your password, OTP, or payment PIN over the phone or chat. If anyone requests this information, report it immediately — it may be a fraud attempt.

2. Why We Collect Your Data

678d collects each piece of information for a specific reason. Nothing is stored without a clear purpose.

For Service Delivery

Basic information is required to create an account, verify logins, process payments, and maintain your gaming history. Without it, 678d cannot provide you with its services.

To ensure security

IP addresses and device information are used to detect suspicious login attempts. This data also helps identify multiple account registrations from the same IP and flag unusual transactions.

To Meet Legal Obligations

Certain data must be retained to comply with international AML (Anti-Money Laundering) and KYC (Know Your Customer) regulations. This is not a choice on 678d's part — it is a legal requirement.

To Improve Your Experience

678d analyzes which games you play most and when you're most active to recommend relevant offers and games tailored to you. This analysis is carried out in a fully anonymized manner.

Contact Us

Your mobile number and email are used to send transaction confirmations, security alerts, and important updates. Marketing messages are only sent with your consent.

3. Who Your Data Is Shared With

678d does not sell your data or share it for advertising purposes. However, there are a limited number of situations where data may be shared:

Payment Partners

Minimal information is shared with bKash, Nagad, and other approved payment providers solely for transaction processing. This data is used exclusively for transaction verification.

Technology Service Providers

Trusted technology partners are involved in managing 678d's servers, cloud services, and cybersecurity. They are bound by strict confidentiality agreements with 678d and may not use your data for any other purpose.

Legal Authorities

If required by a court order or valid legal directive, 678d is obligated to provide relevant data to the appropriate authorities. Where possible, you will be notified in advance.

In the Event of a Company Restructure

In the event of a future merger or acquisition, user data may be transferred to the new entity. Prior notice will be given, and the incoming party will be required to uphold the same privacy policy.

Never: 678d never sells or rents your personal data to advertisers, data brokers, or other gaming companies.

4. How Long Data Is Retained

678d does not retain any data longer than necessary. Retention periods vary depending on the type of data.

  • Account Information: For as long as your account is active, and up to 5 years after closure (as required by law).
  • Transaction Records: Mandatory for 5 years under international AML regulations.
  • KYC Documents: Up to 5 years after account closure.
  • Login Logs & IP Records: 90 days.
  • Cookie Information: 30 days to 1 year, depending on the cookie type.
  • Customer Support Conversations: 2 years from the date of the last message.

Once the retention period expires, data is securely deleted or anonymized. If you submit a deletion request, you will be informed of the deletion process and any data that must be retained.

5. Security Measures

678d uses industry-leading technology to keep your data secure. The key security measures in place are outlined below:

  • 256-bit SSL/TLS Encryption: All data between your browser and 678d's servers is encrypted — the same standard used by banks.
  • Password Hashing: Your password is never stored directly — only a one-way hash is kept. This means even if someone gains access to the database, your actual password remains completely unknown to them.
  • Two-Factor Authentication (2FA): Optional but strongly recommended. When enabled, your account stays secure even if your password is compromised.
  • Firewall & DDoS Protection: Protection against unauthorised access and attacks at the server level.
  • Regular security audits: Third-party cybersecurity experts conduct regular audits of the 678d system.
  • Data Backup: Data is backed up in encrypted form across multiple secure locations.
Your Role: Even with the best technology in place, your own account security depends on you. Use a strong password, keep 2FA enabled, and never share your password or OTP with anyone.

6. Cookie Policy

Cookies are small data files stored in your browser. 678d uses cookies to keep your session active and to improve your overall experience.

Cookie Type

  • Essential Cookies: Essential for login sessions and security. Disabling these will prevent 678d from functioning properly.
  • Performance Cookies: Used to identify pages with errors or slow loading times.
  • Preference Cookies: Remembers your language preference and interface settings.
  • Analytics Cookies: Collects overall usage statistics (no personal data).

Cookie Controls

You can block or delete cookies at any time through your browser settings. Note that disabling essential cookies may affect certain features.

FAQs

Frequently Asked Questions About Your Account

There are a few reasons your 678d account may be locked or blocked. The most common is too many failed password attempts — as a security measure, the account is temporarily locked. In most cases, waiting 30 minutes will allow it to unlock automatically. Another reason could be an incomplete KYC verification — if identity documents haven't been submitted before a large withdrawal, the withdrawal will be blocked, though you should still be able to log in. A third possibility is that 678d's security team has detected suspicious activity and temporarily suspended the account. In any of these situations, contact 678d via live chat for a quick resolution — Bengali-language support is available 24 hours a day. Share your registered mobile number in the chat and the issue will be verified and resolved as quickly as possible. If self-exclusion is active, the account cannot be reopened until the period ends — this is for your own protection. In that case, please contact support.

Opening a new account at 678d is straightforward and takes just a few minutes. To register, you will need: your full name, an active mobile number (bKash or Nagad preferred), your date of birth, and a strong password. Providing an email address is optional but recommended, as important notices are sent there. Once you complete the form, an OTP will be sent to your mobile — verify it and your account is ready. You can start playing and making deposits right away. However, to make your first withdrawal, you must complete KYC verification, which requires a photo of both sides of your National ID card and a selfie holding the card. KYC approval typically takes between 30 minutes and 2 hours. Please note that each person may only hold one account — multiple accounts are strictly prohibited. To get started, click the "Registration" button at the top of the site.
