Last updated: January 2026. This Privacy Policy explains how mahjong333 collects, uses, stores, and protects your personal data in accordance with international best practices. By registering or using our platform, you agree to the terms set out here. Please review this page periodically as we may update it to reflect changes in our practices or legal requirements.
Commitment Privacy We
Mahjong333 takes the protection of your personal data seriously. Below are the six core principles that shape our approach to user privacy.
Bank-Level Encryption
All data transmitted between your device and Mahjong333 servers is protected with 256-bit SSL encryption — the same technology used by leading financial institutions worldwide.
No Data Sale
We never sell, rent, or exchange your personal data to third parties for marketing purposes. Your data remains entirely yours.
Minimum Data Collection
We only collect data that is strictly necessary to provide our services. No excessive information is gathered — data minimisation is a core principle of our operations.
Full User Control
You have the right to access, correct, or request deletion of your personal data at any time. We provide a simple and transparent process for you to manage your own information.
Secure Data Storage
Your data is stored on secure servers with strict access controls. Only authorised personnel may access user data, and every access is logged and audited.
International Standards Compliance
Our privacy policy is designed in line with international data protection standards, ensuring that your personal information is managed to the highest expectations of security and transparency.
01 Information We Collect
Mahjong333 collects the personal information necessary to manage your account, process transactions, and maintain platform security. The types of information we collect include:
- Registration Information: Full name, email address, phone number, date of birth, and the username you choose during account registration.
- Identity Verification Documents (KYC): Copies of your identity card, passport, or other verification documents required to meet compliance requirements and process withdrawals.
- Financial Information: Payment method details, deposit and withdrawal history, and transaction records. We do not store full credit or debit card numbers — this is handled by certified payment providers.
- Usage Data: Game activity, betting records, game preferences, and platform usage patterns.
- Technical Data: IP address, browser type, device type, operating system, and log data collected automatically when you use the platform.
- Communications: Records of conversations with our customer support team, including live chat history and email correspondence.
All of this information is collected either directly from you during registration or your interactions with the platform, or automatically through standard tracking technologies such as cookies and log files.
02 How We Use Your Data
Your personal data is used for legitimate and transparent purposes. We do not use your data for any purpose not stated in this policy. Specifically, your data is used to:
- Manage and maintain your account on the Mahjong333 platform.

- Carry out identity verification (KYC) processes required for security and compliance.
- Provide responsive and effective customer support.
- Send important notifications related to your account, transactions, and security updates.
- Reach you with promotional offers and bonuses — only if you have given consent to receive marketing communications.
- Detect and prevent fraud, money laundering, and other suspicious activities.
- Improve the platform, user interface, and service quality based on aggregated usage data.
- Comply with applicable legal and regulatory obligations.
03 Data Sharing with Third Parties
Mahjong333 does not sell or share your personal data for commercial purposes. However, in the course of operating the platform, we may share necessary information with the following parties:
- Payment Providers: Information required to process your financial transactions is shared with registered and certified payment service providers.
- Game Providers: Minimum technical data required to deliver a smooth gaming experience through third-party provider platforms.

All third parties working with us are required to comply with strict data protection standards and are prohibited from using your data for any purpose other than what has been contractually agreed.

04 Data Security
Mahjong333 continuously invests in security infrastructure to ensure your personal data is protected at all times. Our security measures include end-to-end encryption for all transmitted data, database encryption for stored data, multi-factor access controls for internal systems, and regular security audits by independent experts.
While we take all reasonable steps to protect your data, no system can guarantee absolute security. You also play an important role — use a strong password, do not share your login credentials, and always log out after each session, especially on shared devices.
In the event of any security incident affecting your personal data, we are committed to notifying you within a reasonable timeframe and taking immediate action to address the situation.
05 Data Retention Period
We retain your personal data for as long as necessary to fulfil the purposes stated in this policy or to comply with applicable legal requirements. Generally:
- Active account data is retained for as long as your account remains active on the mahjong333 platform.
- After account closure, data is retained for the minimum period required by law for audit and compliance purposes.
- Financial transaction records are retained in accordance with applicable financial compliance requirements.
- Technical log data is typically retained for a shorter period and is subsequently deleted or anonymised on a regular basis.
Once the retention period has elapsed, your data will be securely deleted or anonymised so that it can no longer be linked back to your identity.
