Your privacy is important to us. This Privacy Policy explains what personal data big321 collects when you use our platform, how we use and protect that data, who we may share it with, and what rights you have over your own information. We are committed to handling your data with transparency, care, and in full compliance with our obligations under applicable data protection frameworks.
These cards summarise the key principles of our privacy practices. The full legal text follows immediately below.
We collect personal data you provide during registration and verification — including your name, date of birth, email address, Malaysian mobile number, and payment details — as well as technical usage data generated automatically when you access the Platform.
Your data is used strictly for account management, identity and age verification (KYC), payment processing, fraud prevention, responsible gambling compliance, and improving your experience on big321. We do not sell your personal data to third parties.
We share data only with carefully selected service providers — payment processors, identity verification services, and licensed gaming software providers — who are contractually bound to handle your data securely and only for the specified purpose.
big321 uses 256-bit SSL encryption, secure server architecture, two-factor authentication, and strict internal access controls. We conduct regular security reviews and require all data processors to adhere to equivalent security standards.
You have the right to access, correct, or request erasure of the personal data we hold about you, subject to our regulatory retention obligations. You may also object to certain forms of processing or request a portable copy of your data.
We use cookies and similar technologies to maintain your session, remember preferences, and analyse Platform performance. You can manage cookie preferences through your browser settings, though some features may be affected if cookies are disabled.
This Privacy Policy (hereinafter "Policy") is published by big321 (hereinafter "big321", "the Company", "we", "us", or "our"), the operator of the online gaming and sports betting platform accessible at https://big321.cam and any associated subdomains or mobile applications (collectively, the "Platform").
big321 serves players across Malaysia, including major urban centres such as Kuala Lumpur, Penang, Johor Bahru, Petaling Jaya, and Shah Alam. This Policy applies to all personal data processed in connection with your access to and use of the Platform, including data collected through our website, mobile applications, live chat system, email correspondence, and any other interaction you have with big321.
This Policy should be read alongside our Terms & Conditions and our Responsible Gambling policy, both of which form part of the overall agreement governing your relationship with big321. By registering an Account, depositing funds, or otherwise using the Platform, you acknowledge that you have read and understood this Policy.
If you have questions about this Policy or wish to exercise any of your data rights, please contact our Privacy team at the details set out in Section 17 of this document.
For the purposes of this Privacy Policy, the following terms carry the meanings set out below:
big321 acts as the Data Controller in respect of all Personal Data collected and Processed through the Platform. As Data Controller, big321 is responsible for determining the purposes for which your Personal Data is Processed and for ensuring that such Processing is carried out lawfully, fairly, and transparently.
big321 operates under an international gaming licence (Curaçao jurisdiction) and is subject to the data handling obligations associated with that regulatory framework. The Company additionally applies privacy principles consistent with internationally recognised standards, including the principles of purpose limitation, data minimisation, storage limitation, and data security.
Where big321 engages third-party Data Processors — including payment gateway providers handling MYR transactions via DuitNow, FPX, Maybank, CIMB, Touch 'n Go eWallet, Boost, GrabPay, Public Bank, and Hong Leong; identity verification service providers; and licensed game content suppliers — big321 enters into formal data processing agreements to ensure that your Personal Data receives equivalent protection in the hands of those processors.
big321 collects the following categories of Personal Data, as detailed in the table below:
| Category | Examples | When Collected |
|---|---|---|
| Identity Data | Full legal name, date of birth, NRIC/MyKad number, passport number, photograph | Registration; KYC verification |
| Contact Data | Email address, Malaysian mobile number, residential address | Registration; profile updates |
| Financial Data | Bank account name / last four digits (Maybank, CIMB, Public Bank, Hong Leong); e-wallet identifiers (Touch 'n Go, Boost, GrabPay); cryptocurrency wallet addresses | Deposit / withdrawal processing; KYC |
| Transaction Data | Deposit amounts, withdrawal requests, game wagers, win/loss records, bonus uptake history | During Platform use |
| Technical Data | IP address, device type, browser type and version, operating system, session timestamps, cookie identifiers | Automatically on Platform access |
| Usage Data | Pages visited, games played, sports markets viewed, search queries, click-through patterns | Automatically during session |
| Communications Data | Live chat transcripts, email correspondence, support tickets | When you contact big321 |
| Responsible Gambling Data | Self-exclusion records, deposit limit settings, cooling-off period data | When tools are activated |
big321 does not intentionally collect Special Category Data. In the event that you voluntarily disclose health-related information (for example, when seeking support through our responsible gambling programme), such data will be handled with the highest level of care and processed solely for the purpose for which it was provided.
big321 collects Personal Data through the following means:
big321 Processes your Personal Data on one or more of the following legal bases:
big321 uses the Personal Data it collects for the following purposes:
big321 does not sell, rent, or trade your Personal Data to any third party for their own independent marketing purposes. Data shared with third parties is limited strictly to what is necessary for the delivery of the relevant service.
big321 may share your Personal Data with the following categories of recipients, solely for the purposes described in this Policy:
big321 will never share your Personal Data with any third party for that party's own marketing purposes. If you receive unsolicited communications purporting to be from big321 or a partner, please report it to our support team immediately.
Given the international nature of big321's operations and the cross-border nature of online gaming services, your Personal Data may be transferred to and Processed in countries outside of Malaysia. This may include the Curaçao jurisdiction (where our gaming licence is held), as well as other jurisdictions where our technology and service providers operate.
Where such transfers occur, big321 takes appropriate safeguards to ensure that your Personal Data continues to receive protection consistent with this Policy. These safeguards include contractual clauses with Data Processors that impose equivalent data protection standards, and where available, reliance on adequacy mechanisms recognised under applicable law.
By using the Platform, you acknowledge and agree to such international transfers as necessary for the provision of the Services described in this Policy.
big321 retains your Personal Data only for as long as is necessary to fulfil the purposes for which it was collected, unless a longer retention period is required by law or our licensing authority. The following retention guidelines apply:
Following expiry of the applicable retention period, Personal Data is securely deleted or anonymised in a manner that prevents reconstruction. Requests for early erasure are considered under the provisions of Section 12 (Your Rights) below, subject to overriding legal retention obligations.
big321 uses cookies and similar tracking technologies (including local storage and session tokens) to operate and improve the Platform. Cookies are small text files stored on your device by your browser. They do not contain executable code and cannot access other data stored on your device.
big321 uses the following categories of cookies:
You may manage or disable non-essential cookies through your browser settings at any time. Please note that disabling functional or analytics cookies may affect the availability of certain Platform features. Specific cookie management instructions vary by browser; consult your browser's help documentation for guidance.
Subject to applicable law and regulatory requirements, you have the following rights with respect to the Personal Data that big321 holds about you. You may exercise any of these rights by contacting our Privacy team as described in Section 17.

Object to Processing based on legitimate interests or for direct marketing purposes. Marketing objections will be actioned immediately.
big321 will respond to all verified rights requests within thirty (30) calendar days of receipt. Where a request is complex or involves a large volume of data, we may extend this period by a further two months, in which case we will notify you of the extension and the reason for it. We may request proof of identity before actioning a request to prevent unauthorised data disclosure.
Certain rights may be limited or restricted where compliance would conflict with big321's legal obligations — particularly with respect to AML record-keeping, KYC retention, and our gaming regulatory requirements. Where a request cannot be fulfilled in full, we will explain the specific reason.
The big321 Platform is strictly intended for individuals aged 21 years and older. big321 does not knowingly collect or Process Personal Data from any person under the age of 21. Age verification is a mandatory component of our registration and KYC process, and access to real-money gaming features is not granted until age has been confirmed.
If big321 becomes aware that it has inadvertently collected Personal Data from a person under 21 years of age, it will take immediate steps to delete that data and close the associated Account. If you believe that a minor has registered on the Platform, please contact us immediately using the details in Section 17.
It is the responsibility of parents and guardians to prevent minors from accessing online gambling platforms. big321 provides parental control guidance on our Responsible Gambling page.
The Platform may, from time to time, contain links or references to third-party websites, services, or content — for example, game provider pages or payment processor interfaces. This Privacy Policy applies solely to data Processed by big321 and does not extend to any third-party platform or service.
big321 does not control the privacy practices of third-party websites and accepts no responsibility for the content or privacy policies of those sites. We encourage you to review the privacy policy of any third-party service before submitting personal information to it.
big321 implements a comprehensive set of technical and organisational security measures to protect your Personal Data against unauthorised access, accidental loss, destruction, or disclosure. These measures include:
While big321 takes all reasonable steps to protect your data, no internet-based system can guarantee complete security. You are responsible for maintaining the security of your own Account credentials and for notifying big321 immediately of any suspected unauthorised access.
big321 reserves the right to update or amend this Privacy Policy at any time to reflect changes in our data Processing practices, applicable law, or our regulatory environment. The date of the most recent revision is displayed at the top of this page.
Where changes are material — for example, where we intend to use your data for a new purpose or share it with a new category of recipient — we will provide advance notice via email to your registered address and/or a prominent notification on the Platform prior to the change taking effect.
Your continued use of the Platform following publication of any revised Privacy Policy constitutes your acceptance of the updated terms. If you do not agree to a material change, you may close your Account by contacting our support team before the change takes effect.
This Privacy Policy was last reviewed and updated on 1 January 2026. We recommend reviewing this Policy periodically to stay informed of how big321 handles your data.

For formal data subject access requests, we may require proof of identity to prevent unauthorised disclosure. Please be prepared to provide a copy of your NRIC/MyKad or other acceptable identity document when submitting a formal rights request.
