kajian4d Platform Privacy Notice

This page describes what we collect when you use kajian4d and how we keep that data protected. We at kajian4d collect personal information—your name, email, identity documents, payment methods, and betting history—only as necessary to operate our platform, comply with anti-money-laundering regulations, and serve your account. We encrypt all data in transit and at rest, never sell your information to third parties, and apply strict retention policies so your data is deleted when no longer needed.

Our kajian4d privacy practices follow international data-protection standards adapted for Indonesian regulations and regional payment processors. When you register, deposit funds via DANA, e-wallet, mobile banking, or bank transfer through local payment and online payment, or claim a weekly cashback promotion, we collect and store the minimum information required. We use third-party payment processors and verification services—all of whom sign strict data-handling agreements with kajian4d—but retain full responsibility for your data security.

Read this notice carefully to understand your rights. If you have questions about how we handle your data, contact our kajian4d support team or submit a data-subject request using the contact details at the end of this page.

What Data We Collect at kajian4d

Account information. When you open a kajian4d account, we collect your full legal name, date of birth, email address, phone number, and residential address. We require this information to verify your identity and comply with know-your-customer (KYC) regulations. You provide this data voluntarily; however, without it, we cannot process your account opening or approve deposits.

Identity and address verification documents. kajian4d requires you to upload a government-issued ID (such as a national ID card or passport) and proof of address (such as a recent utility bill or bank statement). We store scanned copies of these documents for anti-money-laundering compliance and fraud prevention. Our verification team reviews documents once and stores them securely; they are not used for any other purpose.

Game and betting history. We record every wager you place on kajian4d—which game, stake amount, outcome, settlement time, and net result. This data helps us calculate your weekly cashback, track your tier progression, and detect fraudulent or manipulative betting patterns. Your betting history is retained as long as your kajian4d account exists, then deleted according to our retention schedule.

Technical and usage data. Our kajian4d servers automatically collect your IP address, device type, browser version, pages visited, and session duration. We use this data to troubleshoot technical issues, prevent fraud and account takeovers, and improve platform performance. This technical data is retained for up to 12 months.

How We Use Your Data

We at kajian4d use your personal data for the following purposes:

• Account administration: To create and manage your kajian4d account, verify your identity, and process deposits and withdrawals.
• Regulatory compliance: To comply with anti-money-laundering (AML) laws, sanctions screening, and gaming regulations in your jurisdiction.
• Fraud prevention: To detect suspicious activity, prevent account takeover, and protect you and kajian4d from financial crime.
• Promotional eligibility: To verify that you qualify for welcome offers, weekly cashback, tier progression, and other kajian4d promotions, and to calculate your rewards accurately.
• Customer support: To assist you when you contact kajian4d support, investigate disputes, and resolve account or settlement issues.
• Platform improvement: To analyse usage patterns, identify technical issues, and improve kajian4d features and user experience.
• Legal obligations: To comply with court orders, government requests, or other legal requirements in your jurisdiction or ours.

We do not use your data for marketing or selling to third parties. kajian4d may send you account-related emails (welcome message, tier upgrades, cashback credits, withdrawal confirmations), but you are not enrolled in marketing communications by default. If you wish to opt out of account notifications, contact our support team.

Data Security, Retention & Your Rights

How we protect your data. We at kajian4d encrypt all personal data in transit using TLS (Transport Layer Security) encryption and at rest using AES-256 encryption. Our servers are hosted in secure data centres with 24/7 physical and digital monitoring. Access to your data is restricted to authorised kajian4d staff and is logged for audit purposes. We conduct regular security reviews and penetration testing to identify and address vulnerabilities before they can be exploited.

Third-party processors and data location. kajian4d partners with payment processors, identity verification services, and cloud hosting providers to operate our platform. These third parties process your data only on our behalf and under strict confidentiality agreements. Our servers may be located outside your jurisdiction—we use data centres in multiple regions to ensure platform availability. By using kajian4d, you consent to your data being processed and stored in these locations, subject to the same encryption and security standards we apply locally.

Data retention. We retain your kajian4d account data (name, email, address, identity documents, betting history) while your account is active and for up to 7 years after account closure to comply with financial recordkeeping laws. Technical logs (IP addresses, session data) are deleted after 12 months. Payment transaction records are retained for 5 years for tax and AML compliance. If you request account deletion, we anonymise your data but retain core records needed for legal, tax, and fraud prevention purposes.

Your trust is fundamental to kajian4d. We treat your personal data with the same care we apply to our own, using best-practice encryption, minimal collection, and strict access controls.
