Privacy Policy Kuwin55

1Scope of this policy

This privacy policy applies to all personal data that kuwin55 collects and processes when you use the platform at kuwin55.vu — including the website, mobile application, and any other services provided by kuwin55.

This document is written in Vietnamese and is intended exclusively for users accessing the platform through the Vietnamese interface. By creating an account, logging in, or continuing to use any service on kuwin55, you confirm that you have read and agree to the contents described in this privacy policy.

2Data We Collect

Kuwin55 only collects data necessary to operate its services, ensure account security, and comply with operational requirements. The table below describes the main data categories:

Kuwin55 does not actively collect sensitive data such as health information, religion, or political views. If you voluntarily share such information during a support interaction, we use it solely to address your specific request.

3Purpose of data use

Data you provide or that the system automatically collects is used for the following specific purposes:

• Account operations: Create and manage accounts, verify identity, handle logins, and maintain active sessions.
• Transaction processing: Recording, verifying, and completing deposit, withdrawal, and wagering transactions on the platform.
• Customer support: Responding to requests, resolving disputes, and providing technical support via live chat or email.
• Security and fraud prevention: Detecting unusual activity, preventing fake account creation, bonus fraud, and other forms of abuse.
• Service improvement: Analyzing usage behavior to optimize the interface, improve performance, and develop new features suited to Vietnamese users.
• Communication and notifications: Sending transaction notifications, policy updates, promotional information (if you have opted in), and important security alerts.
• Compliance with operational requirements: Record retention for internal requirements and to respond to requests from competent authorities when required by law.

4Legal Basis for Data Processing

Kuwin55 processes your personal data on the basis of one or more of the following:

• Performance of contract: Data processing necessary to deliver the services you have registered for and use on kuwin55.
• Consent: For activities such as sending marketing emails, kuwin55 only does so with your explicit consent. You may withdraw your consent at any time.
• Legitimate interest: Fraud prevention, protecting platform integrity, and improving services — all carried out with respect for your privacy.
• Legal obligation: In cases where it is necessary to comply with requests from competent authorities under applicable law.

5Data Sharing with Third Parties

Kuwin55 does not sell your personal data. In certain cases necessary for service operation, data may be shared with the following parties:

• Payment service providers: Payment processors handling deposits and withdrawals receive the information needed to complete transactions — they are bound by strict confidentiality agreements.
• Game software providers: Game developers on the platform receive session data necessary to operate the game — this does not include personally identifiable information.
• Technical support service providers: Partners providing infrastructure, hosting, and security services — they are granted access only to the minimum data necessary.
• Legal authorities: When a legitimate request is received from a competent authority, kuwin55 may provide information as required by law — this is done only when there is a clear legal basis.

6Cookies and Tracking Technologies

Kuwin55 uses cookies and similar tracking technologies to improve user experience and operate the platform more effectively. There are three main types of cookies in use:

• Essential cookies: Required for the platform to function — maintaining login sessions, remembering bet slips, and ensuring transaction security. You cannot disable this type of cookie without affecting core functionality.
• Analytics cookies: Collecting anonymous data about how you use the platform — which pages you visit most, which features you use most — so kuwin55 can improve its interface and user experience.
• Customization cookies: Remembering your settings and preferences such as language, interface, and notification settings so you do not need to reconfigure them each time you log in.

You can manage your cookie preferences through your browser settings. However, disabling cookies may affect certain features of the kuwin55 platform.

7Data Security Measures

Kuwin55 applies multiple layers of technical and organizational measures to protect your personal data from unauthorized access, loss, or unauthorized disclosure:

• 256-bit SSL/TLS connection encryption for all data transmitted between your device and our servers.
• Passwords are encrypted using a one-way hashing algorithm — even kuwin55 staff cannot view your original password.
• Internal access control follows the principle of least privilege — staff may only access the data necessary for their role.
• Intrusion detection and anomaly monitoring systems operate continuously 24/7.
• Regular data backups and a disaster recovery plan to ensure service continuity.
• Periodic security reviews and system updates in response to emerging threats.

8Data retention period

Kuwin55 retains your personal data for as long as necessary to fulfill the purposes stated in this policy, or as required by applicable law:

• Active account: Data is stored for the duration the account remains active, plus any additional period required thereafter.
• After account closure: Transaction data and activity logs are retained for a minimum of 5 years after account closure in accordance with internal fraud prevention requirements.
• Identity verification data: KYC profiles and verification documents are retained for an extended period in accordance with internal compliance requirements.
• Cookies and session data: Deleted according to the expiration settings of each cookie type, ranging from when the browser is closed to a maximum of 2 years.

After the retention period expires, data will be securely deleted or anonymized.
