hi31 Privacy Policy

hi31 is an online betting and casino platform accessible at https://hi31.io, providing sports betting, live casino games, slots, and fishing games to adult players throughout Bangladesh. The platform operates in English and processes all financial transactions in Bangladeshi Taka (BDT).

Privacy is a fundamental value at hi31. We recognise that the personal data you share with us — whether during registration, identity verification, or day-to-day platform use — is sensitive information that deserves rigorous protection. This Privacy Policy has been written to be clear, transparent, and accessible so that you understand precisely how your data is handled.

This Policy applies to all personal data collected through the hi31 website (https://hi31.io), any mobile-optimised interfaces, and all communications between you and the hi31 support team. It covers data collected from registered players, prospective registrants who visit the site, and individuals who contact us for support purposes.

This Privacy Policy should be read alongside the hi31 Terms & Conditions. Where there is any conflict between this Policy and the Terms & Conditions on a matter of data handling, this Privacy Policy shall prevail.

hi31 collects personal data from you in several ways: directly from you when you register or interact with the platform; automatically as you use the site; and from third-party verification and payment service providers. The categories of personal data we collect are described in detail below.

2.1 Registration Data

When you create a hi31 account, we collect the following information:

• Full legal name
• Date of birth (for age verification — players must be 21 or older)
• Residential address, including city and district (e.g., Dhaka, Chittagong, Sylhet, Khulna, Rajshahi)
• Email address
• Mobile phone number
• Preferred username and encrypted password
• Account currency preference (BDT)

2.2 Identity Verification (KYC) Data

To comply with anti-money laundering obligations and to verify that players meet the minimum age requirement of 21 years, hi31 may request the following documents:

• National Identity Card (NID) or valid passport — front and back copies
• Proof of residential address — utility bill or bank statement dated within the past 3 months
• Proof of payment method ownership — bKash account confirmation, bank statement, or card statement
• Selfie photograph held alongside government-issued identification

KYC documents are processed securely and retained only for the period required by applicable legal and regulatory obligations.

2.3 Financial Transaction Data

When you make deposits or withdrawals, hi31 collects transactional data including:

• Payment method type (e.g., bKash, Nagad, Rocket, Upay, Visa, Mastercard, bank transfer)
• Transaction amount in BDT
• Transaction timestamps and reference numbers
• Partial payment account identifiers (e.g., masked mobile wallet numbers)

hi31 does not store full card numbers, CVV codes, or full mobile banking PINs. Payment card data is handled exclusively by our PCI-compliant payment processing partners.

2.4 Gameplay and Betting Data

As you use the hi31 platform, we automatically record:

• Bets placed, game rounds participated in, and wagering history
• Win and loss records across sports betting, live casino, slots, and fishing game products
• Bonus and promotion usage history
• Session durations and login timestamps
• Responsible gaming settings you have applied to your account

2.5 Technical and Device Data

When you visit https://hi31.io, our servers automatically collect certain technical information:

• IP address and approximate geographic location (country/city level)
• Browser type and version
• Operating system and device type (desktop, mobile, tablet)
• Pages visited, time spent on each page, and navigation patterns
• Referring URL (the page that directed you to hi31)

2.6 Communications Data

If you contact the hi31 support team via email or live chat, we retain records of those communications, including your messages, the date and time of contact, and the resolution reached. This data is used to improve service quality and to maintain records in the event of disputes.

hi31 uses the personal data we collect for the following purposes:

hi31 does not use your personal data for automated decision-making that produces legal or similarly significant effects, except where required by fraud prevention or anti-money laundering systems. Where automated checks flag an account for review, a human member of the hi31 team will assess the situation before any significant action is taken.

hi31 processes your personal data under the following legal bases:

• Contractual Necessity: Processing required to fulfil the terms of the player agreement, including account creation, transaction processing, and service delivery.
• Legal Obligation: Processing required to comply with anti-money laundering obligations, age verification requirements, and other applicable legal duties.
• Legitimate Interests: Processing carried out to pursue hi31's legitimate business interests, including fraud prevention, platform security, service improvement, and responsible gaming monitoring, where these interests are not overridden by your fundamental rights and freedoms.
• Consent: Where you have given explicit consent to a specific form of data processing, such as receiving promotional communications or optional analytics. You may withdraw consent at any time by contacting [email protected].

Where hi31 relies on legitimate interests as the legal basis for processing, we conduct a balancing test to ensure that our interests do not disproportionately impact your privacy rights. You may request information about these balancing assessments by contacting [email protected].

hi31 does not sell, rent, or trade your personal data to any third party. We share personal data only in the following limited and controlled circumstances:

5.1 Payment Service Providers

To process deposits and withdrawals, hi31 shares relevant transactional and identity data with payment partners including bKash, Nagad, Rocket, Upay, Dutch-Bangla Bank, City Bank, BRAC Bank, and international card processors such as Visa and Mastercard. Data shared with payment providers is limited strictly to what is required to complete the transaction and comply with payment provider security requirements.

5.2 Identity Verification Partners

KYC verification is conducted with the assistance of certified identity verification service providers. Your NID, passport, and supporting documents may be shared with these providers solely for the purpose of confirming your identity and age. All KYC partners are contractually bound to maintain the confidentiality and security of your data.

5.3 Game Content Providers

hi31 sources games from third-party studios including Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Ezugi, and Spribe. Game providers may receive anonymised or pseudonymised session data for the purpose of game performance monitoring. These providers do not receive your name, contact details, or financial information.

5.4 Fraud Prevention and Security Services

To protect the integrity of the platform and safeguard all players, hi31 may share data with fraud detection services and cybersecurity partners. Data shared for fraud prevention is processed under strict confidentiality terms and is not retained by security partners beyond the period required to complete their assessment.

5.5 Legal and Regulatory Disclosure

hi31 may disclose personal data where required to do so by applicable law, court order, or at the request of a law enforcement authority or financial regulatory body. In such cases, hi31 will disclose only the minimum amount of data necessary to satisfy the legal requirement and will, where permitted by law, notify the affected player of the disclosure.

hi31 uses cookies and similar technologies on the platform. A cookie is a small text file placed on your device by a website server. Cookies allow hi31 to recognise your device, maintain your session, and understand how players interact with the platform.

6.1 Types of Cookies We Use

• Essential Cookies: Required for the platform to function correctly. These include session authentication cookies that keep you logged in as you navigate the site, security cookies that help prevent CSRF attacks, and load-balancing cookies. Essential cookies cannot be disabled without impairing platform functionality.
• Analytical Cookies: Used to understand how players navigate the hi31 platform, which pages are most visited, and where technical issues occur. Analytical data is aggregated and anonymised. hi31 uses this information solely to improve the platform experience.
• Preference Cookies: Store your platform preferences such as display settings, language preference (English), and responsible gaming reminder settings, so these do not need to be re-entered on each visit.

6.2 Managing Cookies

You can manage or delete cookies through your browser settings. Most modern browsers allow you to block or delete all cookies, or selectively manage them by site. Please note that disabling essential cookies will impair your ability to log in and use the hi31 platform. Disabling analytical or preference cookies will not prevent you from using core platform features.

Browser-specific cookie management instructions are available in the help documentation of your browser (Chrome, Firefox, Safari, Edge, Opera). hi31 does not control third-party cookies that may be set by game studio iframes embedded within the platform — please refer to the relevant studio's privacy policy for information on their cookie practices.

6.3 No Advertising Tracking

hi31 does not deploy advertising tracking pixels, retargeting scripts, social media tracking widgets, or third-party ad network cookies on the platform. Your browsing activity on hi31 is not used to serve you advertisements on other websites.

hi31 retains personal data for the period necessary to fulfil the purposes described in this Privacy Policy, subject to any longer retention periods required by applicable law. The following retention framework applies:

Following the expiry of the applicable retention period, hi31 will securely delete or anonymise your personal data. Anonymised data (from which you cannot be identified) may be retained indefinitely for statistical and analytical purposes.

hi31 implements a comprehensive set of technical and organisational security measures to protect your personal data against unauthorised access, accidental loss, destruction, or disclosure. Our security framework includes:

• SSL/TLS Encryption: All data transmitted between your device and the hi31 platform is encrypted using industry-standard TLS 1.2 or higher. The padlock icon in your browser address bar confirms your connection is secure.
• Encrypted Data Storage: Personal and financial data stored on hi31 servers is encrypted at rest. Database access is restricted to authorised system personnel only.
• Access Controls: hi31 applies a strict need-to-know access control policy. Employees can only access player data that is directly relevant to their role. All internal data access is logged and audited.
• Two-Factor Authentication: hi31 supports two-factor authentication (2FA) for player accounts, providing an additional layer of security beyond username and password.
• Penetration Testing: hi31 conducts periodic security assessments and penetration tests on its platform infrastructure to identify and remediate vulnerabilities.
• Incident Response: hi31 maintains a data breach response procedure. In the event of a breach that is likely to affect player rights and freedoms, hi31 will notify affected players and relevant authorities in accordance with applicable requirements.

Despite these measures, no system is entirely immune from security threats. You are responsible for maintaining the security of your own account credentials. hi31 strongly recommends using a unique, strong password for your account and enabling two-factor authentication where available.

As a data subject, you have the following rights with respect to the personal data hi31 holds about you:

• Right of Access: You may request a copy of all personal data hi31 holds about you. We will provide this information within a reasonable timeframe upon verification of your identity.
• Right to Rectification: If any personal data hi31 holds about you is inaccurate or incomplete, you have the right to request that it be corrected. You can update many details (such as your contact number or address) directly through your account settings.
• Right to Erasure: You may request that hi31 delete your personal data where it is no longer necessary for the purposes for which it was collected, or where you withdraw consent and there is no other legal basis for processing. Note that certain data must be retained for legal and regulatory compliance purposes and cannot be deleted on request.
• Right to Restriction: You may request that hi31 restrict the processing of your personal data in certain circumstances — for example, while a dispute about data accuracy is being resolved.
• Right to Data Portability: Where processing is based on your consent or on a contract, and is carried out by automated means, you may request that hi31 provide your personal data in a structured, commonly used, machine-readable format.
• Right to Object: You have the right to object to processing based on hi31's legitimate interests. If you object, hi31 will cease processing unless it can demonstrate compelling legitimate grounds that override your interests, rights, and freedoms.
• Right to Withdraw Consent: Where processing is based on your consent, you have the right to withdraw that consent at any time without affecting the lawfulness of processing carried out prior to withdrawal.

To exercise any of the above rights, please submit a written request to [email protected] with your full name, registered email address, and a clear description of your request. hi31 will respond within a reasonable timeframe and may request proof of identity before processing your request.

hi31 is strictly an adult platform. Players must be 21 years of age or older to register and use any service on hi31. We do not knowingly collect personal data from individuals under the age of 21.

hi31 implements age verification procedures at the point of registration and during the KYC process to confirm that all players meet the minimum age requirement. If hi31 discovers or is notified that personal data belonging to a person under the age of 21 has been collected, that data will be deleted promptly and the associated account will be permanently closed.

Parents and guardians who believe that a minor may have registered on hi31 are encouraged to contact the support team immediately at [email protected]. hi31 cooperates fully with parent and guardian concerns regarding underage access. We also recommend that parents use reputable parental control software to restrict access to online gambling platforms at the device or network level.

The hi31 platform may contain links to third-party websites or services — for example, links to payment partner support pages or game provider information pages. This Privacy Policy applies exclusively to personal data collected and processed by hi31. hi31 has no control over and accepts no responsibility for the privacy practices of third-party websites.

Before submitting personal data to any third-party website, we encourage you to review that website's own privacy policy. hi31 is not responsible for the content, security, or privacy practices of any third-party site accessed through links on the hi31 platform.

hi31 reserves the right to update or revise this Privacy Policy at any time to reflect changes in our data processing practices, applicable law, or platform features. Where a change is material — meaning it affects how we use your personal data in a significant way — hi31 will notify registered players via their registered email address and/or through an on-platform notification prior to the change taking effect.

The effective date at the top of this document will be updated each time the Privacy Policy is revised. We encourage you to review this page periodically so that you remain informed about how hi31 protects your data. Continued use of the hi31 platform after the effective date of any revision constitutes your acceptance of the updated Privacy Policy.

Previous versions of the Privacy Policy are archived and can be made available upon request by contacting [email protected].
