639 Privacy Policy — Our Commitment to Protecting Your Information

1. Introduction

Welcome to 639.vin. Our Privacy Policy ("Policy") explains our practices regarding your personal information — what we collect, why we collect it, and how it is used. By using any 639 service, you agree to this Privacy Policy.

We believe every user owns their own data. At 639, privacy is not just a legal obligation — it is a fundamental user right. Our entire data management process is built on transparency and accountability.

2. What Information We Collect

639 collects two types of information — what you provide directly and what is gathered automatically as you use the platform.

A. Information You Provide

• At registration: full name, date of birth, email address, and mobile number.
• Identity Verification (KYC): a copy of your national ID, passport, or driving license.
• Payment details: Mobile Banking/Nagad/Rocket number or bank account information.
• Information provided when contacting us: support tickets, chat messages, or emails.
• Additional information provided when participating in surveys or promotions.

B. Automatically Collected Information

• Device information: IP address, browser type, operating system, device ID.
• Usage information: page visits, game sessions, click patterns, and session duration.
• Transaction history: logs of deposits, withdrawals, and betting activity.
• Session data collected through cookies and tracking technologies.
• Location data (only with your permission).

3. How Your Information Is Used

639 uses collected data solely for specified purposes. We never use your information unnecessarily or without authorization.

4. Data Sharing Policy

639 never sells your personal information. However, your data may be shared in the following limited circumstances:

• Service Provider Partners: Payment gateways, game providers, and technology companies that help deliver services on behalf of 639. All partners are bound by strict confidentiality agreements.
• Law Enforcement: Data may be disclosed to authorities where required by court order or legal obligation.
• Anti-Money Laundering (AML): There is a legal obligation to report suspicious financial activity to the relevant regulatory authorities.
• Business Restructuring: In the event of a merger or acquisition, your data may be transferred to the new entity — with the same privacy protections remaining in place.

5. Cookies & Tracking Technologies

639 uses cookies to enhance your browsing experience. Cookies are small text files stored on your device.

• Essential Cookies: Required for login sessions and security. These cannot be disabled.

6. Data Retention Period

How long we retain your data depends on the type of information and applicable legal requirements. General guidelines are provided below:

• Account Information: For the duration of the account and 5 years after closure.
• Financial Transaction Records: Minimum 7 years as required by law.
• KYC Documents: 5 years after account closure.
• Customer Support Contact: 3 years after resolution.

Once the required retention period expires, your data is securely deleted or anonymized.

9. Information of Minors

639 does not knowingly collect data from anyone under the age of 18. If we become aware that a minor has created an account, that account will be closed immediately and all associated data will be deleted.

10. International Data Transfers

639's servers may be located in various countries. If your data is transferred outside your home country, we ensure that the destination country has adequate data protection measures in place. For international data transfers, we use EU Standard Contractual Clauses or equivalent safeguards.
