At mt661, your personal data is handled with the same discretion we bring to every part of the platform. This policy explains exactly what we collect, why we collect it, and how it is protected.
These cards summarise mt661's core data-handling commitments. They complement — but do not replace — the full policy clauses set out below.
All personal data transmitted between your device and the mt661 platform is protected by industry-standard TLS/SSL encryption. Stored data is held on secure servers with access restricted to authorised personnel only, operating under strict confidentiality obligations.
mt661 collects only the personal data necessary to deliver the services you request — account management, payment processing, identity verification, and customer support. We do not collect data for its own sake or store information beyond the period required for its stated purpose.
mt661 does not sell, rent, or trade your personal data to third parties for their own marketing or commercial purposes. Data shared with service providers — such as payment processors and KYC verification partners — is limited to what those providers strictly require and is governed by data-processing agreements.
You have the right to access the personal data mt661 holds about you, request corrections, ask for data deletion (subject to legal retention obligations), and object to certain processing activities. All such requests are handled by our support team within the timeframes set out in Clause 10.
mt661 uses cookies and similar technologies exclusively to keep you logged in, remember your preferences, and gather anonymised analytics that help us improve the platform. We do not use third-party advertising cookies or tracking pixels that follow you across other websites.
Whenever this Privacy Policy is materially updated, mt661 will notify you by email to your registered address at least 7 days before the changes take effect. The current version and effective date are always displayed at the top of this page. Continued use of the platform constitutes acceptance.
Notice: This Privacy Policy applies to all personal data processed by mt661 in connection with the mt661.app platform, including the sportsbook, casino, slots, virtual sports, and crash game products, as well as all associated customer support and payment services. Please read it carefully alongside the mt661 Terms & Conditions.
For the purposes of this Privacy Policy, the following terms carry the meanings set out below:
This Privacy Policy applies to all Personal Data collected and processed by mt661 in connection with the operation of the mt661.app platform and any associated services, including customer support communications delivered via live chat, email, and WhatsApp.
The mt661 platform is designed primarily for players located in Indonesia. By registering an account or using any mt661 service, you confirm that you are at least 21 years of age and consent to the processing of your Personal Data in the manner described in this Policy.
This Policy does not apply to third-party websites that may be accessible via links placed on the mt661 platform in contexts such as game-studio promotions. mt661 is not responsible for the privacy practices of any third-party site, and you should review those sites' own privacy policies before providing any personal information to them.
mt661 collects the following categories of Personal Data that you provide at the time of account registration, during KYC verification, or in the course of using our services:
| Category | Examples | When Collected |
|---|---|---|
| Identity Data | Full name, date of birth, nationality, national ID number (KTP), passport number | Registration & KYC |
| Contact Data | Email address, WhatsApp / phone number, city of residence (e.g., Jakarta, Surabaya, Bandung) | Registration |
| Financial Data | Bank account number (BCA, BRI, BNI, Mandiri), e-wallet ID (OVO, DANA, GoPay, ShopeePay), transaction history, deposit and withdrawal amounts in IDR | Deposit / Withdrawal |
| Verification Documents | Scanned or photographed copies of government-issued ID, selfie with ID, proof of address | KYC verification |
| Support Communications | Live chat transcripts, email correspondence, WhatsApp message content | Customer support interactions |
When you access the mt661 platform, we automatically collect certain technical data, including:
In certain circumstances, mt661 may receive Personal Data about you from third-party sources, including:
Data received from third-party sources is used only for the specific purpose for which it was obtained and is subject to the same security standards applied to data you provide directly.
mt661 uses the Personal Data described in Clause 3 for the following purposes:
mt661 processes your Personal Data on the following legal bases:
mt661 shares Personal Data with carefully selected third-party service providers who process data on our behalf and under our instructions. These include:
All Data Processors engaged by mt661 are required to: (a) process Personal Data only on mt661's documented instructions; (b) implement appropriate technical and organisational security measures; and (c) not engage sub-processors without mt661's prior written consent.
mt661 may disclose Personal Data to law enforcement agencies, regulatory bodies, or courts where required to do so by law, court order, or valid regulatory demand. mt661 will notify affected Players of such disclosures where legally permitted to do so.
In the event that mt661's business or assets are acquired, merged with, or transferred to another entity, Personal Data held by mt661 may form part of the transferred assets. Affected Players will be notified in advance of any such transfer, and the acquiring entity will be required to honour the commitments set out in this Privacy Policy.
mt661 does not sell, rent, lease, or otherwise commercially exploit your Personal Data to any third party for their own independent purposes. This commitment applies regardless of the commercial value of the data involved.
Some of mt661's third-party service providers — including game studio technology partners and cloud infrastructure providers — operate servers located outside Indonesia. Where Personal Data is transferred to jurisdictions that may not provide a level of data protection equivalent to Indonesian standards, mt661 implements appropriate safeguards including contractual data-transfer clauses that oblige the receiving party to maintain protections equivalent to those described in this Policy.
By using the mt661 platform, you acknowledge and consent to the transfer of your Personal Data to the jurisdictions in which our service providers operate, subject to the safeguards described above.
The mt661 platform uses the following categories of cookies:
| Cookie Type | Purpose | Duration |
|---|---|---|
| Strictly Necessary | Session management, login state, CSRF protection, load balancing | Session / 24 hours |
| Functional | Remembering language preferences, odds format (decimal/fraction), last-visited sport category | 30 days |
| Analytics | Anonymised page-view counts, session duration, navigation flow — used to improve platform usability | 12 months |
mt661 does not use: third-party advertising cookies; social media tracking pixels; cross-site behavioural tracking technologies; or any cookie that tracks your activity outside the mt661.app domain.
You may control cookie settings through your browser preferences. Disabling strictly necessary cookies will prevent you from logging into your mt661 account. Disabling functional or analytics cookies will not affect your ability to use core platform features but may result in a less personalised experience.
Clearing all cookies from your browser will log you out of your mt661 session. If you are in the middle of a live betting session, please confirm all open bets are settled before clearing browser data.
mt661 retains Personal Data for as long as necessary to fulfil the purposes for which it was collected, subject to the following minimum retention periods:
Upon expiry of the applicable retention period, Personal Data is securely deleted or anonymised. Players may request early erasure of certain data categories in accordance with the rights described in Clause 10, subject to our legal retention obligations.
As a player on the mt661 platform, you hold the following rights in respect of your Personal Data. To exercise any of these rights, contact the mt661 support team via live chat or at [email protected]. mt661 will acknowledge all data rights requests within 48 hours and provide a substantive response within 30 days.
You have the right to request a copy of the Personal Data mt661 holds about you, along with information about how that data is processed, the categories held, the purposes of processing, and the recipients to whom data has been disclosed.
If any Personal Data mt661 holds about you is inaccurate or incomplete, you have the right to request that it be corrected. Corrections to identity-critical data (name, date of birth) will require re-verification of supporting documents.
You may request deletion of your Personal Data where: (a) it is no longer necessary for the purposes for which it was collected; (b) you withdraw consent and no other legal basis applies; or (c) the data has been unlawfully processed. This right is subject to mt661's legal obligations to retain certain data categories, as described in Clause 9.
You may request that mt661 restrict the processing of your Personal Data in circumstances where: the accuracy of the data is contested; the processing is unlawful but you prefer restriction over deletion; or you have objected to processing pending verification of mt661's legitimate grounds.
Where processing is based on consent or contractual necessity and is carried out by automated means, you have the right to receive your Personal Data in a structured, machine-readable format, and to request that it be transferred directly to another controller where technically feasible.
You have the right to object to processing based on mt661's legitimate interests, including profiling for fraud prevention purposes. mt661 will cease such processing unless we can demonstrate compelling legitimate grounds that override your rights, or the processing is necessary for the establishment, exercise, or defence of legal claims.
Where processing is based on your consent — including consent to receive marketing communications — you may withdraw that consent at any time. Withdrawal does not affect the lawfulness of processing carried out before withdrawal. To unsubscribe from marketing communications, use the unsubscribe link in any mt661 marketing email or contact the support team directly.
How to submit a data request: Contact mt661 customer support via 24/7 live chat or email us at [email protected]. For identity verification purposes, data rights requests must include confirmation of the registered email address and may require submission of a supporting identity document before processing.
mt661 implements a multi-layered technical and organisational security programme designed to protect your Personal Data against unauthorised access, accidental loss, destruction, or disclosure. Key measures include:
In the event of a data security incident that is likely to result in a risk to your rights and interests, mt661 will notify affected Players without undue delay and will take immediate remediation steps.
The mt661 platform is strictly for individuals aged 21 and over. mt661 does not knowingly collect or process Personal Data from individuals under 21 years of age. Age verification is performed as part of the account registration and KYC process.
If mt661 becomes aware that Personal Data has been collected from an individual under 21 years of age, that data will be deleted immediately and the associated account will be closed. If you believe that a minor has registered an account on the mt661 platform, please contact us immediately at [email protected].
The mt661 platform may display links to third-party content in specific contexts — for example, links to sports data providers or game-studio promotional content. These links are provided for informational purposes only. mt661 has no control over the content, privacy practices, or data-handling procedures of any third-party website, and this Privacy Policy does not apply to any site outside the mt661.app domain.
mt661 recommends that you review the privacy policy of any third-party site before providing that site with any personal information. The presence of a link to a third-party site on the mt661 platform does not constitute an endorsement of that site's privacy practices.
mt661 reserves the right to update or amend this Privacy Policy at any time. Material changes — defined as changes that affect the categories of data collected, the purposes for which data is used, the third parties with whom data is shared, or your rights as a data subject — will be communicated to you via email to your registered address at least 7 days before the amended Policy takes effect.
Minor or technical amendments (such as corrections to typographical errors or clarifications that do not change the substance of the Policy) may be made without individual notification, and the updated Policy will be published on this page with a revised effective date.
The version of this Privacy Policy published on this page with the date shown at the top is the currently operative version. Continued use of the mt661 platform following the effective date of any amendment constitutes your acceptance of the revised Policy.
For any questions, concerns, or formal requests relating to this Privacy Policy or mt661's data-processing practices, please contact us through the following channels:
mt661 acknowledges all Privacy Policy queries within 48 hours and aims to provide a full response within 30 days. Where a request is particularly complex or where you have submitted multiple requests, the response period may be extended by a further 30 days; you will be notified of any such extension within the initial 30-day window.
If you are dissatisfied with mt661's response to a data rights request or with our data-handling practices more broadly, you have the right to lodge a complaint with the relevant data protection authority in your jurisdiction.
Reminder: This Privacy Policy was last updated on 1 January 2026. Continued use of the mt661 platform after this date confirms your acceptance. For the most current version, always refer to this page at mt661.app/privacy-policy.
