These legal terms define how mahyong138 operates your account, handles your data, and sets the boundaries of service access — all subject to local law and eligible regions in Indonesia. Read this page before you open an account so you understand what applies to you from day one.
Our legal framework governs the relationship between you and mahyong138 from the moment you create an account. Access to the platform — including live casino tables, slot rooms, and sportsbook markets — is available only where local law permits. We do not extend service to regions where access is restricted or prohibited under applicable regulation. When you submit account details, initiate a Bank Transfer, or complete a QRIS payment, those actions are governed by the terms set out here and by the conditions shown at the point of each transaction. We do not override the instructions displayed in your account wallet with any verbal or informal arrangement. Data you provide during account registration — name, contact details, wallet identifiers — is held in accordance with this policy and used only for account operation, transaction processing, and support. We do not sell or share your personal data with third parties for marketing purposes outside the scope of this policy. If any part of this policy conflicts with a local legal requirement in your region, the local requirement takes precedence to the extent of that conflict. We update these terms when the service or regulatory context changes; the current version is always the one shown on this page.
Transactions via Bank Transfer fall within the scope of this policy. Limits and verification steps are shown in your account at the time of each transaction.
QRIS payments are processed under the conditions displayed during checkout. This policy covers how transaction records are retained and how disputes are routed.
DANA deposit and withdrawal records are held as part of your account history. You can review these records in your account dashboard after login.
OVO-linked transactions are subject to the same data retention and dispute terms as other supported payment methods outlined in this policy.
Not every part of your experience on mahyong138 falls under the same policy rules. Account access, payment transactions, site content, and third-party services each sit in a different position under this framework. Understanding that boundary helps you know where to direct a question or dispute.
Login credentials, account creation, and session activity fall fully within this policy. Rules covering account suspension, reactivation, and data correction are described here and enforced by our support team.
Bank Transfer, QRIS, DANA, and OVO transactions are covered for data retention and dispute routing. Processing times and fee structures are shown at the point of each transaction in your wallet, not governed by this document alone.
Game titles from JDB, Joker, Microgaming, and PlayStar are displayed in the lobby as available content. Game rules, RTP disclosures, and feature mechanics are governed by each studio's own terms, not by this policy.
External payment processors, e-wallet providers, and studio platforms operate under their own terms. Where a third-party service intersects with your account, we note the handoff point — but we cannot extend this policy's coverage beyond our platform boundary.
This policy gives you concrete, actionable rights over your account and data — not just reading material. You can review the transaction records tied to your account at any time by navigating to the history section in your account dashboard after login. If a detail in your account profile is incorrect — name spelling, contact address, or wallet identifier — you can submit a correction request through the support channel, and our team will process it against the verification documents you provide. If you believe a transaction has been recorded incorrectly, or that your account data has been handled outside the terms described here, you have the right to raise a formal question. We handle those requests through the contact paths listed in the support section below. Where local law grants additional data rights in your region, those rights apply on top of what is described here — they are not replaced by this policy.
Your transaction history — Bank Transfer entries, QRIS payments, DANA deposits — is visible in your account dashboard. No request is needed to access your own history; login and navigate to the history tab.
Submit a correction request via our support channel with the updated detail and the relevant verification document. Our team will confirm the change or explain what additional step is needed.
If something in this policy is unclear or you believe a term has been applied incorrectly to your account, open a query through live chat or email. We respond to policy questions with a written reply, not only a scripted answer.
You can ask how a specific piece of your data is used and retained. We will confirm the use case in writing, referencing the relevant section of this policy, within the response window shown on the support page.
Policy questions and account disputes are handled through dedicated contact routes. Use the channel that matches the urgency and nature of your query — live chat for account-access issues that need a same-session response, email for written policy clarifications, and the in-account help form for transaction-specific disputes tied to Bank Transfer or QRIS records.
Open the chat widget from any page on mahyong138. State your account username and the policy section your question relates to. Our team can access your account record during the session to address the issue directly.
Send your policy query or data correction request to our support email address, shown on the contact page after login. Include your registered account name and a description of the specific policy point or transaction in question.
For transaction disputes — DANA, OVO, Bank Transfer, or QRIS entries — use the help form inside your account dashboard. This routes your query directly to the team that holds access to payment logs and account history.
Account security and data handling are operational commitments, not policy decoration. We store account credentials and transaction records in a protected environment; access is limited to the teams that require it to operate your account or respond to a verified support request. Cookies used on this site serve session continuity and account state — they are not used to build advertising profiles shared externally.
Account data and transaction records are retained for the period required by applicable regulations in supported regions. After that period, data is deleted or anonymised. The retention period for your account is shown in the policy detail section above.
Session cookies keep your account active while you browse the lobby and switch between slots, live tables, and the sportsbook. Persistent cookies are used only for preferences you set in your account. No advertising or cross-site tracking cookies are placed without your acknowledgement.
We require identity verification at account creation and at certain transaction thresholds. The specific steps — document type, verification field, confirmation method — are shown in your account at the point they are triggered, not pre-set universally.
If you want to update how your data is used, request a record deletion, or ask about the basis for a specific data-handling decision, contact us via the email path listed in the support section. We confirm receipt and provide a written response.
These are the questions we hear most often about how this policy works in practice — covering your data, account rights, contact options, and how jurisdiction affects what applies to you.
Access and policy coverage depend on local law and whether your region is eligible. Where access is permitted under local law in Indonesia, this policy governs your account. If your region restricts platform access, this policy does not extend service eligibility — it only governs accounts that are lawfully open.
Your full transaction history — including DANA deposits, QRIS payments, and Bank Transfer entries — is shown in the history tab of your account dashboard. No separate request is needed. Log in and navigate to the transaction history section to view, filter, and review each entry.
Yes. Submit a correction request through live chat or email support, including the detail you want changed and a supporting verification document. Our team will confirm the correction or let you know if an additional step is required before the change can be applied to your account.
We collect the details you enter during registration — name, contact address, and wallet identifier — along with transaction data generated by your activity. This data is used for account operation, payment processing, and responding to support requests. It is not shared with third parties for external marketing.
Use the in-account help form in your dashboard. Select the transaction in question from your history and submit a dispute description. This routes directly to the team with access to payment logs. For complex cases, follow up via email so there is a written record of the full exchange.
You can submit a deletion request via the email contact path shown on the support page after login. We will confirm receipt and advise on the applicable retention period before deletion. Some records may be retained for the period required by regulation even after a deletion request is processed.
