mahjong77Privacy Policy

This page describes what we collect when you use mahjong77 and how we keep that data protected. We operate a gaming platform available where local law permits, and we take data security as seriously as we take payment settlement. Your information—whether it's your email, payment details, or identity documents—lives in encrypted systems with limited access. We don't sell your data to third parties, and we don't use it for marketing without your consent. This policy applies to all users accessing mahjong77 via Android app, iOS browser, or desktop, regardless of whether you're in Jakarta, Surabaya, Bandung, Medan, Semarang, or Yogyakarta.

Our data collection practices centre on what's necessary to operate the platform and comply with financial regulations. We collect your email during account creation, your identity documents during KYC verification, and your payment method information when you deposit or withdraw. We also track your gameplay activity—which games you play, when you play them, and your session history—so we can troubleshoot issues and detect fraud. None of this data leaves mahjong77's servers without your explicit instruction, such as when you request a withdrawal to your DANA, e-wallet, mobile banking, or other linked account.

We maintain separate encryption layers for different data types. Your account credentials (email and password) sit in one secured environment. Your identity documents (KTP, address proof, selfie) sit in another. Your payment routing information (bank account or e-wallet details) sits in a third. This compartmentalisation means a breach in one system does not expose all your information. We review our security posture quarterly and maintain audit logs for all data access.

What we collect on mahjong77 and why

We collect your email address when you create an account. We use this to verify your identity, send password-reset links, and notify you of account activity (such as withdrawals or failed deposits). We do not use your email to add you to marketing lists unless you opt in through your account settings. We collect your phone number optionally—if you provide it, we use it only for two-factor authentication or urgent account recovery, never for marketing calls or SMS promotions.

We collect your full name, date of birth, and government ID details (KTP number or passport number) only during KYC verification before your first withdrawal. We store these documents encrypted and retain them for the duration of your account plus seven years for regulatory compliance. We never share this information with payment processors or third-party marketers. Our compliance team accesses these documents only when verifying your identity or investigating a dispute.

We collect payment information—your DANA, e-wallet, mobile banking, local payment, online payment, e-wallet, mobile banking, local payment, online payment, or e-wallet account details—only when you initiate a deposit or withdrawal. We tokenise this information so we never store your raw bank account number or e-wallet credentials. When you request a withdrawal, we route funds directly to the payment method you originally used; we don't retain payment details between transactions unless you explicitly save a payment method for future use.

How we use your data

We use your email, account name, and gameplay history to operate mahjong77—to manage your account balance, settle your bets, process your deposits and withdrawals, and provide customer support. We analyse your gameplay patterns only to detect suspicious activity (such as rapid account creation and deletion, or deposits followed immediately by large payouts). We do not sell this data to advertisers or data brokers. We do not profile you for behavioural targeting. We do not share your data with third-party analytics firms without your consent.

Third-party processors and international transfers

Our servers may sit outside your jurisdiction—we operate infrastructure across multiple regions for redundancy and speed. This means your data may be processed in countries with different privacy laws than Indonesia. However, we maintain the same encryption and access controls regardless of server location. We use third-party payment processors (such as Verifone, Midtrans, or similar payment-gateway providers) to route your mobile banking, local payment, and bank-transfer deposits. These processors handle your transaction data according to their own privacy policies, but we contractually require them to protect your information to at least our standards.

We do not share your identity documents with payment processors. We do not share your full transaction history with marketing firms. The only third parties who access your data are: payment networks (to route your money), our compliance vendor (to verify your identity), and our customer-support team (to help resolve your issues). Each of these relationships is governed by a data-protection contract.

We keep your data compartmentalised by access level—support staff see your account history but not your KYC documents; compliance staff see your identity but not your payment credentials; no one person sees everything.

Cookies and tracking

We use essential cookies to keep you logged into mahjong77—these are session cookies that expire when you close your browser. We use analytics cookies (such as Google Analytics or similar) to understand how users navigate our platform, so we can improve performance and fix bugs. You can disable non-essential cookies through your browser settings without losing core functionality. We do not place tracking pixels on third-party sites, and we do not use cookies to build a cross-site profile of your browsing behaviour.

Policy updates and effective date

We may update this privacy policy as our platform evolves or regulations change. We will notify you of material changes by email or through an in-app notice before the change takes effect.
