mahjong33 Platform Privacy Notice
We at mahjong33 encrypt all account data using 256-bit SSL and store payment information in separate secure vaults isolated from our gaming servers. This privacy notice describes what data we collect when you register, deposit, withdraw, and play on mahjong33, how we use it, and what rights you have over your information.
Our commitment is to process only the data needed for account verification, payment settlement, Game Rules compliance, and fraud prevention. We do not sell your data to marketing agencies or use it for purposes unrelated to mahjong33 operations. Third-party processors—payment gateways, KYC providers, and data centres—handle subsets of your data under strict confidentiality agreements.
If you have questions about how we handle your information, our contact details appear at the end of this notice. We respond to data-access and deletion requests within 30 days where local law permits.
Data We Collect on mahjong33
We collect the following categories of data when you use mahjong33:

- Verification data: Government ID number, full name, address, date of issue of ID documents, proof-of-address document (utility bill or bank statement)

How We Use Your Data on mahjong33
We use the data above for these purposes:
- Account verification and identity checks: We verify your government ID against public databases and confirm your address using document comparison. This step prevents fraud, money laundering, and underage account creation.
- Payment processing: Our payment partner, which operates payment gateways in Jakarta, Surabaya, Bandung, Medan, and Semarang, uses your bank details or e-wallet account number to process deposits and withdrawals. We do not store full bank account numbers after the initial transaction.
- Compliance and regulatory reporting: If regulators in supported jurisdictions request account data, we share it to comply with legal obligations. We also use betting history to detect patterns of problem gambling.
- Fraud prevention: We monitor for suspicious login patterns, duplicate accounts, and payment mismatches using automated systems. If we detect anomalies, we may block your account temporarily and request additional verification.
- Game and odds administration: We store your betting and gaming history to settle bets correctly, calculate your account balance, and audit game outcomes for fairness.
- Customer support: When you contact our support team via email or in-app chat, we log your message and use it to respond to your inquiry.
Third-Party Processors and Data Sharing
We rely on third-party services to deliver mahjong33. These processors access subsets of your data:
- Payment gateways: e-wallet, mobile banking, local payment, online payment, e-wallet, and your bank (mobile banking, local payment, online payment, e-wallet) receive your account number, deposit amount, and timestamp when you fund your account.
- KYC and ID verification provider: A licensed third-party identity verification firm receives your government ID and address proof to confirm your identity. We delete their copy after verification is complete; we retain only the confirmation result.
- Data centre operator: Our servers may be located outside Indonesia. The data centre operator has access to encrypted account data, betting records, and payment transaction logs but cannot decrypt them without our encryption keys.
- Analytics and monitoring: We use automated systems to analyse betting patterns, game fairness, and platform performance. These systems process your game outcome data but do not share it externally.
- Customer support platform: Our support ticketing system stores email and in-app messages. Support staff access these tickets to respond to your inquiries.
We do not share your data with marketing agencies, affiliate networks, or social media platforms. We do not sell your email address or betting history.
