Privacy Policy

This Privacy Policy describes how line4d ("we", "us", "our", or "the Company") collects, processes, stores, and protects the personal data of individuals ("you", "Player", "User") who access or use the line4d platform located at https://line4d.cam, including all associated services, features, and content.

This policy applies to all registered players and visitors to the Platform, regardless of the device or method of access. It covers personal data collected through the website itself, our live chat support system, email correspondence with our support team, and any other direct communication channel you use to interact with line4d.

By registering an account or using the Platform, you acknowledge that you have read and understood this Privacy Policy and consent to the processing of your personal data as described herein. If you do not agree with any aspect of this policy, you should not use the Platform.

We collect personal data through the following channels: account registration, identity verification (KYC), deposit and withdrawal transactions, gameplay activity, customer support interactions, and technical data generated automatically when you access the Platform. The categories of personal data we collect are as follows:

2.1 Identity and Contact Data

• Full legal name (as it appears on your government-issued ID);
• Date of birth (for age verification — you must be 21 or older);
• Registered email address;
• Mobile phone number (if provided for two-factor authentication);
• Residential address (city and province level — required for KYC and fraud prevention).

2.2 Identity Verification (KYC) Documents

• Indonesian National Identity Card (KTP) or passport;
• Driver's license (as a secondary document, where requested);
• Selfie photograph taken alongside the KTP/passport (liveness check).

2.3 Financial Data

• Indonesian bank account details (account number and bank name — e.g., BCA, BRI, BNI, Mandiri, CIMB Niaga, OCBC NISP) registered in your name for withdrawal processing;
• E-wallet identifiers for OVO, DANA, GoPay, ShopeePay, or LinkAja accounts registered in your name;
• Transaction history (deposit amounts, withdrawal amounts, timestamps, and reference numbers);
• We do not store full card numbers or bank account passwords — payment processing is handled through secure, tokenized channels.

2.4 Usage and Gameplay Data

• Betting history across all product categories (sports, live casino, togel, slots, crash games);
• Session duration, login timestamps, and gameplay frequency;
• Bonus activation and wagering activity;
• Self-imposed limit settings and responsible gaming tool usage.

2.5 Technical and Device Data

• Device type, operating system, and browser version;
• Session cookies and unique device identifiers;
• Platform interaction logs for security and fraud monitoring purposes.

line4d processes personal data only for specified, explicit, and legitimate purposes. We do not use your data in any manner inconsistent with the purposes listed at the time of collection. The primary uses of your personal data are as follows:

• Account creation and management: Setting up your player account, maintaining your profile, and authenticating your identity at login;
• Age and identity verification (KYC): Confirming that you meet the minimum age requirement of 21 years and that your identity details are accurate and verifiable;
• Transaction processing: Facilitating deposits via BCA, BRI, BNI, Mandiri, and supported e-wallets, and processing withdrawal requests to your registered payment method;
• Fraud prevention and AML compliance: Monitoring account activity for indicators of money laundering, account takeover, bonus abuse, or other prohibited conduct as defined in our Terms & Conditions;
• Responsible gaming monitoring: Tracking gameplay patterns to identify signs of problem gambling and applying limits or restrictions where requested by the player or required by our responsible gaming obligations;
• Customer support: Responding to your inquiries, resolving disputes, and managing complaint escalations;
• Platform security: Detecting and preventing unauthorized access, protecting against DDoS attacks, and maintaining the integrity of the Platform's technical infrastructure;
• Legal and regulatory compliance: Retaining records as required by applicable anti-money laundering regulations and responding to lawful requests from competent authorities;
• Service improvement: Analyzing aggregated, anonymized usage data to improve Platform performance, user experience, and game content offerings — this analysis does not involve individual-level profiling for marketing purposes.

All personal data processing carried out by line4d rests on one or more of the following recognized legal bases:

• Contractual necessity: Processing required to perform the contract between you and line4d — including account registration, transaction processing, and customer support — is carried out on the basis of contractual necessity;
• Legal obligation: Certain processing activities — particularly identity verification, transaction record-keeping, and AML reporting — are required by applicable law and are carried out on that basis;
• Legitimate interests: We process technical and security data on the basis of our legitimate interest in operating a safe, fraud-resistant platform. These interests are balanced against your privacy rights and do not override them;
• Consent: Where processing is not otherwise justified by the above bases — for example, sending promotional communications — we will seek your explicit consent. You may withdraw consent at any time by contacting our support team.

We may share your personal data with the following categories of recipients, strictly limited to what is necessary for the stated purpose:

• Payment processors and banking partners: Indonesian banks (BCA, BRI, BNI, Mandiri, CIMB Niaga, OCBC NISP) and e-wallet providers (OVO, DANA, GoPay, ShopeePay, LinkAja) receive only the transaction data required to process your deposits and withdrawals. These partners are bound by their own regulatory obligations and applicable data protection standards;
• Identity verification providers: Our KYC verification process may involve a vetted third-party identity verification service that processes your KTP or passport image and liveness check data solely for verification purposes. No KYC data is retained by the verification provider beyond the period required for the check;
• IT infrastructure and hosting providers: Our Platform is hosted on secure, enterprise-grade cloud infrastructure. Hosting providers access only the technical data necessary to operate and maintain servers and have no access to your personal account data beyond their operational role;
• Customer support platform providers: Our live chat and ticketing system is operated through a trusted support platform. Support agents access your account data only to the extent necessary to resolve your inquiry;
• Competent authorities and regulators: We will disclose personal data to law enforcement, financial intelligence units, or other government authorities where required to do so by a valid legal obligation, court order, or lawful regulatory request. We will notify you of such disclosure where permitted to do so by law;
• Corporate restructuring: In the event of a merger, acquisition, or sale of substantially all assets of line4d, your personal data may be transferred to the successor entity, subject to the same privacy protections set out in this policy.

The line4d Platform uses cookies — small text files stored in your browser — for the limited purposes of maintaining your session, securing your account, and measuring platform performance. We do not deploy advertising cookies, behavioral tracking cookies, or cross-site tracking technologies.

The specific cookie types used on the Platform are:

• Strictly necessary cookies: These are essential for the Platform to function. They maintain your login session, preserve your bet slip contents, and enforce security tokens. These cookies cannot be disabled without breaking core Platform functionality;
• Performance and analytics cookies: These cookies collect anonymized, aggregated data about how players navigate the Platform — which pages are visited most frequently, average session duration, and where errors occur. This data is used exclusively for internal platform improvement and is not linked to your individual identity;
• Security cookies: These cookies help us detect and prevent fraud, bot activity, and account takeover attempts. They record signals such as login frequency, navigation speed, and device fingerprint characteristics for anomaly detection.

line4d implements a comprehensive set of technical and organizational security measures to protect your personal data against unauthorized access, loss, destruction, alteration, or disclosure. Our security framework includes:

• Transport Layer Security (TLS 1.3): All data in transit between your device and our servers is encrypted using industry-standard TLS 1.3 with 256-bit keys;
• AES-256 encryption at rest: Sensitive personal data stored in our databases — including KYC documents and financial identifiers — is encrypted at rest using AES-256 symmetric encryption;
• Access controls: Access to personal data is restricted to authorized line4d personnel on a strict need-to-know basis. All internal access is logged and audited regularly;
• Two-factor authentication (2FA): Players are encouraged to enable 2FA on their accounts. All internal administrative access to production systems requires multi-factor authentication;
• Regular penetration testing: Our Platform undergoes periodic independent security assessments, including penetration testing and vulnerability scanning, conducted by qualified third-party security firms;
• Incident response plan: In the event of a data security incident that poses a risk to your rights and freedoms, we will notify affected players without undue delay and take immediate remediation steps.

We retain personal data only for as long as is necessary to fulfill the purpose for which it was collected, or as required by applicable law. The following retention schedule applies:

Once the applicable retention period expires, personal data is securely deleted or irreversibly anonymized in accordance with our internal data disposal procedures.

As a player on the line4d Platform, you hold the following rights with respect to your personal data. To exercise any of these rights, contact our support team via live chat or at the plain-text email address provided in Section 14.

We will respond to all valid data rights requests within 30 calendar days of receipt. In complex cases, this period may be extended by a further 30 days, and we will notify you of the extension and the reason for it. There is no charge for exercising your rights, provided requests are not manifestly unfounded or excessive.

If you are a parent or guardian and believe that a minor in your care has created an account on the line4d Platform, please contact our support team immediately using the contact information in Section 14. We will investigate and take appropriate action without delay.

line4d operates on international cloud infrastructure, which means that your personal data may be stored on or processed by servers located outside of Indonesia. Where such transfers occur, we ensure that appropriate safeguards are in place to protect your data to a standard equivalent to that described in this Privacy Policy.

Safeguards we apply to international data transfers include:

• Transferring data only to jurisdictions that maintain adequate data protection standards as recognized by internationally accepted frameworks;
• Entering into data processing agreements with all sub-processors that impose obligations equivalent to those in this Privacy Policy;
• Applying end-to-end encryption to data in transit across all international network pathways.

The line4d Platform does not contain links to third-party websites in its navigational structure. However, certain game content provided by licensed studio partners (such as Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, or Pocket Games Soft) may be delivered via embedded iframes or API integrations from those studios' servers.

While line4d carefully vets all game studio partners, we are not responsible for the privacy practices of those studios' own data collection activities within their game environments. We recommend reviewing the privacy policies of individual game providers if you have specific concerns about data collected within a particular game title.

line4d reserves the right to update or revise this Privacy Policy at any time to reflect changes in our data processing practices, applicable legal requirements, or platform features. When material changes are made, we will:

• Update the "Last updated" date at the top of this page;
• Send a notification email to all registered players at their registered email address, summarizing the key changes;
• Display a prominent notice on the Platform for a minimum of 14 days prior to the revised policy taking effect.

Your continued use of the Platform after the effective date of any revised Privacy Policy constitutes your acceptance of the updated terms. If you do not agree with the revised policy, you may request account closure and withdrawal of your remaining balance in accordance with the procedures set out in our Terms & Conditions.

If you have any questions, concerns, or requests relating to this Privacy Policy or the way line4d handles your personal data, our Data Support team is available 24 hours a day, 7 days a week via the live chat function on the Platform.
