Your privacy matters to us. This policy explains exactly what personal data hay4d collects, why we collect it, how we use and protect it, and the rights you hold over your own information.
These six principles guide every decision we make about your personal data at hay4d.
All data transmitted between your device and hay4d servers is protected by 256-bit TLS encryption. Stored personal and financial data is encrypted at rest, accessible only to authorised personnel.
We collect only the data we genuinely need to operate hay4d services. We do not harvest excess information, and each data point is tied to a clear, documented purpose described in this policy.
hay4d does not sell, rent, or trade your personal information to third parties for their own marketing or commercial purposes — under any circumstances and for any price.
This policy is written in plain English so you always know exactly what data we hold, who can see it, and why. No buried clauses — what you read here is the complete picture.
You have the right to access, correct, export, or delete your personal data at any time. hay4d honours all data subject requests promptly — typically within 5 business days of verification.
Bank details for BCA, BRI, BNI, Mandiri, CIMB Niaga, BSI, and e-wallets OVO, DANA, GoPay, ShopeePay, and LinkAja are stored in tokenised form — raw account numbers are never exposed in our systems.
hay4d ("we", "us", "our", or the "Platform") is committed to protecting the privacy and personal data of every individual who accesses or uses our online gaming platform at https://hay4d.one. This Privacy Policy describes in full and transparent detail how we collect, use, store, share, and safeguard your personal information when you interact with any part of the hay4d platform — including our sports betting, live casino, slot games, togel (Indonesia's traditional numbers lottery), baccarat, and slot tournament offerings.
This Policy applies to all registered Members, prospective players who browse the platform without creating an account, and any individuals who contact our customer support team. By accessing hay4d, creating an account, making a deposit, or placing a bet, you acknowledge that you have read, understood, and consent to the data practices described herein.
This Privacy Policy should be read alongside our Terms & Conditions and our Responsible Gaming Policy, both of which are incorporated by reference. In the event of a conflict between this Policy and any other document, this Privacy Policy prevails with respect to personal data matters.
Language Note: This Privacy Policy is written in English, which is the official language of the hay4d platform. If you require clarification in Bahasa Indonesia, our 24/7 customer support team includes native Indonesian-speaking agents who can assist you.

hay4d collects personal data through the following primary channels:
We process your personal data only for the specific, documented purposes listed below. We do not use your data for any purpose beyond those described in this Policy without first obtaining your explicit consent or establishing a new lawful basis.
hay4d processes your personal data on one or more of the following legal bases, depending on the purpose and category of data involved:
hay4d does not sell, rent, or commercially transfer your personal data to third parties. We share your data only to the limited extent necessary for the delivery of our services, and only with trusted partners who are contractually bound to protect it. The categories of recipients are as follows:
hay4d may disclose your personal data to competent government bodies, law enforcement agencies, or financial intelligence units where required to do so by applicable law, valid court order, or regulatory directive. We will notify you of such a disclosure where we are legally permitted to do so.
In the event that hay4d undergoes a merger, acquisition, or sale of substantially all of its assets, your personal data may be transferred to the successor entity as part of that transaction. We will provide notice of any such transfer and the applicable privacy terms of the successor entity prior to your data being transferred.
No Third-Party Marketing: Under no circumstances does hay4d share your personal data with third-party advertisers, data brokers, or marketing agencies for their own commercial use. Your email address and phone number will never be sold or transferred for marketing purposes outside hay4d.
hay4d retains personal data only for as long as is necessary to fulfil the purpose for which it was collected, or as required by applicable law. The following retention schedules apply:
| Data Category | Retention Period |
|---|---|
| Account & Identity Data | For the duration of the active account, plus 5 years following account closure (to satisfy AML record-keeping obligations). |

Upon expiry of the applicable retention period, personal data is securely deleted or irreversibly anonymised. Anonymised data may be retained for statistical and analytical purposes without time limit, as it no longer constitutes personal data.
hay4d implements a comprehensive, layered security programme to protect your personal data against unauthorised access, disclosure, alteration, or destruction. Our key technical and organisational security measures include:
Your Responsibility: While hay4d protects data on our end, you play an important role too. Keep your account password strong and unique. Never share your login credentials with anyone.

hay4d is an adult gaming platform. Access to all hay4d services is strictly restricted to individuals who are 21 years of age or older. This age restriction is actively enforced through our account registration process and KYC verification programme.
hay4d does not knowingly collect, store, or process personal data belonging to individuals under the age of 21. If we become aware that a person under 21 has registered an account or submitted personal data to our platform, we will immediately and permanently close that account, delete all associated personal data, void any related transactions, and forfeiture any balances in accordance with our Terms & Conditions.
If you are a parent or guardian and have reason to believe that a minor in your care has registered on hay4d or submitted their personal data to us, please contact us immediately at support @hay4d.one. We will investigate and act on all such reports within 24 hours.
21+ Commitment: hay4d uses date-of-birth verification at registration and document-based age verification (KYC) before processing any withdrawal. Any account found to belong to a person under 21 will be closed without notice and reported to the relevant authorities where required by law.
