sistem4dPrivacy Policy
This page describes what we collect when you use sistem4d and how we keep that data protected. When you open an account, log in from your mobile device, or withdraw funds via DANA or your bank account, we record information necessary to verify your identity, process your transactions, and comply with applicable law. We do not sell your personal data to third parties; we use it only to operate our platform, process payments, and protect against fraud.
We at sistem4d understand that your privacy matters. Our policy explains the types of data we collect (email, national ID, payment details), how we store them (encrypted, on secure servers), who may access them (our staff, payment processors, legal authorities if required), and what rights you have to view, update, or delete your information. We do not track you across other websites; our data collection is limited to your account activity on sistem4d.
By using our platform, you agree to this privacy policy. If you do not agree with any part of it, do not create an account or use sistem4d.
What Data We Collect on Our Platform
Our Data Collection During Account Opening
When you register on sistem4d, we collect your email address, password, phone number, national ID number, and proof of address. Your email and phone are used to verify your account and send you notifications about deposits, withdrawals, and account changes. Your national ID and address proof are part of our KYC (Know Your Customer) process, which is mandatory for account security and legal compliance. We do not collect your national ID photograph unless you request account recovery or our risk team requests additional verification.
We store this information encrypted on our servers. We do not share your national ID with third parties except when required by law or to our payment processors for fraud prevention. Your password is hashed using industry-standard encryption; we never store it in plain text. If you forget your password, we email you a reset link; you create a new password only after confirming your identity via a code sent to your registered email.
Transaction Data We Record on sistema4d
We record every deposit and withdrawal you make on sistem4d, including the payment method (DANA, e-wallet, mobile banking, local payment, online payment, e-wallet, or bank virtual account), the amount, timestamp, and status (pending, confirmed, failed). We store the last four digits of your payment card or bank account number, but we do not store full card details or banking passwords. All transaction data is encrypted and logged for your account history, fraud prevention, and compliance with financial regulations.
We record your game activity—which sports markets you wagered on (Liga 1, Piala AFF, Champions League, Premier League, MotoGP, badminton), which live-dealer tables you joined (blackjack, roulette, baccarat, Dragon Tiger), which slots you played (Aviator, Sweet Bonanza, Gates of Olympus, Fortune Tiger, Mahjong Ways), and which esports events you followed (Mobile Legends, Free Fire, PUBG Mobile). This data helps us understand which products are popular, detect fraud, and provide you with personalized notifications about upcoming games.
Device and Usage Information
When you use sistem4d on Android or iOS, we log your device type, operating system version, app version, and your IP address. This helps us diagnose technical issues, prevent unauthorized access, and understand which devices our users prefer. We use this information only for platform maintenance and security; we do not share it with advertisers or marketers. If you access sistem4d from multiple cities—Jakarta, Surabaya, Bandung, or Medan—we detect this for security verification; if your location changes drastically between sessions, we may request additional identity confirmation.
- KYC (Know Your Customer)
- Mandatory identity verification we perform when you open your account, using your national ID and proof of address.
- Encryption
- We protect your data by encoding it so only authorized servers can read it; this prevents unauthorized access even if our servers are compromised.
- Hash
- A one-way encryption method for passwords; we cannot reverse it to see your password, only verify that a password you enter matches the stored hash.
How We Use Your Data and Your Privacy Rights
Our Use of Your Information
We use your email and phone to verify your account, send you login confirmations, notify you of deposits and withdrawals, and alert you to suspicious account activity. We use your payment information to process your transactions via DANA, e-wallet, mobile banking, local payment, online payment, or your bank (e-wallet, mobile banking, local payment, online payment). Our payment processors receive your payment details to facilitate transfers; they are contractually bound to protect your data and use it only for processing transactions.
We analyze your game activity (in aggregate, not individually) to understand which sports, live-dealer games, or slots are popular, to detect fraud, and to improve our platform. We do not use your data to profile you or make automated decisions about your eligibility to play. We do not sell your email or contact information to third parties. We do not use your data for marketing purposes unless you opt in (and you may opt out anytime from Settings).
Your Rights Regarding Your Data on sistema4d
You have the right to view all personal data we hold about you by requesting it through our support team. We provide a copy of your account information, transaction history, and game records within a reasonable timeframe. You have the right to correct inaccurate information—if your email or phone number changes, update it in your Settings immediately. You have the right to delete your account and request that we erase your data, though we may retain transaction records for legal compliance and fraud prevention for a limited period after account closure.
Third-Party Access and Legal Compliance
Our payment processors (e-wallet, mobile banking, local payment, bank processors) receive your payment information to process deposits and withdrawals. They operate under their own privacy policies and are not controlled by sistem4d. We do not share your account data with advertisers, data brokers, or marketing firms. If we receive a legal request from law enforcement or a court, we comply with the request only if it is lawful and specifically targets your account. We do not volunteer information about our users to authorities; we respond only to valid legal demands with proper judicial oversight.
Our servers may sit outside your jurisdiction; your data may be processed in countries with different privacy laws. By using sistem4d, you consent to this international data transfer. We undertake to apply the same encryption and security standards regardless of server location.
Data Retention and Account Closure
We retain your account data as long as your account is active. If you close your account, we retain transaction records, KYC documents, and game history for a period required by law (typically several years for anti-money-laundering compliance). We erase personal data (email, phone, address) after your account closure period expires, though we may retain anonymized statistical data. If you request data deletion before the legal retention period ends, we will anonymize your data (remove your name and identity) but may retain transaction records for compliance.
