bigtka Privacy Policy

This Privacy Policy ("Policy") describes how bigtka ("the Company", "we", "us", "our"), operating the online casino and sports betting platform at bigtka.net, collects, uses, stores, discloses, and protects the personal information of individuals who register for, access, or use the bigtka Platform ("you", "the Player", "the User").

bigtka is committed to handling your personal data responsibly, transparently, and in accordance with applicable data protection principles. We collect only the information we genuinely need to operate the Platform, verify your identity, process your transactions, and comply with our legal obligations. We do not engage in unnecessary data collection, and we do not monetise your personal information by selling it to advertisers or data brokers.

This Policy should be read alongside our Terms & Conditions and our Responsible Gaming policy. Together, these documents form the complete framework governing your relationship with the bigtka Platform.

When you create a bigtka account, we collect the information you provide during the registration process. This typically includes your full name, date of birth, email address, mobile phone number, and your chosen username. This data is essential for creating and maintaining your account, verifying that you meet the 18+ age requirement, and communicating with you about your account.

To comply with our anti-money laundering and responsible gaming obligations, bigtka may request that you complete a Know Your Customer (KYC) verification process. This may require you to submit copies of government-issued identity documents such as your National ID card or passport, proof of residential address, and proof of ownership of any payment method you use. KYC documents are processed securely and retained only for as long as required by our legal obligations.

When you make a deposit or withdrawal on the bigtka Platform, we collect information related to that transaction. This includes the payment method used (such as bKash, Nagad, Rocket, or Upay), the transaction amount in Bangladeshi Taka (৳), the date and time of the transaction, and a tokenised reference to your payment account. bigtka does not store full mobile banking account numbers or PIN codes on its own servers.

We maintain records of your gameplay and betting activity on the Platform, including the games you play, bet amounts, wager history, game outcomes, bonus usage, and session durations. This data is used for account management, dispute resolution, responsible gaming monitoring, and fraud detection.

When you access the bigtka Platform, we automatically collect certain technical information, including your IP address, browser type and version, operating system, device type, screen resolution, referring URL, and the pages or features you interact with during your session. This information is collected via server logs and analytics tools and is used to maintain the security, stability, and performance of the Platform.

If you contact our support team via live chat, email, or WhatsApp, we retain records of those communications, including the content of your messages and any attachments you share. These records are kept to ensure quality of service, resolve disputes, and maintain an audit trail for compliance purposes.

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

• Account management: Creating, maintaining, and securing your bigtka account, and verifying your identity and age eligibility (18+).
• Transaction processing: Facilitating deposits and withdrawals via supported payment methods including bKash, Nagad, Rocket, and Upay, and maintaining accurate financial records.
• Legal compliance: Fulfilling our obligations under anti-money laundering regulations, responsible gaming requirements, and other applicable laws.
• Fraud prevention and security: Detecting, investigating, and preventing fraudulent activity, unauthorised account access, and abuse of the Platform.
• Responsible gaming: Monitoring gameplay patterns to identify potential problem gambling behaviours and intervening appropriately where necessary.
• Customer support: Responding to your enquiries, resolving disputes, and providing technical assistance.
• Platform improvement: Analysing aggregated usage data to improve the performance, reliability, and user experience of the bigtka Platform.
• Marketing communications: Sending promotional offers, bonus notifications, and news about new games or features — but only where you have opted in to receive such communications.

bigtka processes your personal data on the following legal bases:

• Contractual necessity: Processing your registration data, KYC documents, and transaction data is necessary to perform the contract between you and bigtka and to provide you with access to the Platform.
• Legal obligation: Processing your identity verification and financial transaction data is necessary to comply with applicable anti-money laundering, fraud prevention, and regulatory requirements.
• Legitimate interests: Collecting technical and gameplay data serves bigtka's legitimate interests in maintaining the security, integrity, and performance of the Platform, and in preventing fraud and abuse.
• Consent: Sending marketing communications and setting non-essential cookies requires your prior consent. You may withdraw your consent at any time without affecting the lawfulness of processing carried out before withdrawal.

bigtka may share your personal data with carefully selected third-party service providers who assist us in operating the Platform. These include payment processors (such as bKash, Nagad, Rocket, and Upay), identity verification providers, fraud detection services, cloud hosting providers, and analytics partners. All such providers are bound by contractual obligations to process your data only as instructed by bigtka and to maintain appropriate security standards.

Games on the bigtka Platform are supplied by third-party studios including Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, and Ezugi. These studios may receive certain technical data (such as a session token) necessary to load and run their games within the bigtka Platform. They do not receive your name, contact details, or payment information.

bigtka may disclose your personal data to law enforcement agencies, regulatory bodies, or other competent authorities where required to do so by applicable law, court order, or legal process. In such cases, bigtka will disclose only the minimum data necessary to satisfy the legal requirement.

In the event of a merger, acquisition, restructuring, or sale of all or part of bigtka's business, your personal data may be transferred to the acquiring entity as part of that transaction. bigtka will notify affected users of any such transfer and of any material changes to the way their data is processed.

bigtka does not sell, rent, or trade your personal information to any third party for their own marketing or commercial purposes. This commitment is absolute and applies to all categories of personal data we collect.

Cookies are small text files stored on your device when you visit a website. bigtka uses cookies and similar tracking technologies (such as local storage and session tokens) to maintain your session state, remember your preferences, and gather anonymised usage statistics.

• Essential cookies: Required for the Platform to function correctly. These include session authentication cookies that keep you logged in and cookies that maintain your language and display preferences. These cannot be disabled without affecting Platform functionality.
• Analytics cookies: Used to collect anonymised data about how players interact with the Platform — such as which pages are most visited, how long sessions last, and where users encounter errors. This data is aggregated and does not identify individual players.
• Security cookies: Help detect and prevent fraudulent activity, bot traffic, and unauthorised access attempts.
• Preference cookies: Store your chosen settings (such as notification preferences) so that they persist across sessions.

You can manage or disable non-essential cookies through your browser settings. Please note that disabling certain cookies may affect the functionality of the bigtka Platform. Instructions for managing cookies can be found in your browser's help documentation. Your cookie preferences can also be updated from within your bigtka account settings at any time.

bigtka retains your personal data for as long as is necessary to fulfil the purposes for which it was collected, or as required by applicable legal and regulatory obligations. The following general retention periods apply:

• Account and registration data: Retained for the duration of your account and for a period of five (5) years following account closure, to comply with anti-money laundering record-keeping requirements.
• KYC and identity verification documents: Retained for a minimum of five (5) years following the completion of the verification process, as required by financial crime prevention regulations.
• Transaction records: Retained for a minimum of five (5) years following each transaction, as required by applicable financial record-keeping obligations.
• Gameplay and betting history: Retained for a period of two (2) years following the relevant activity, for dispute resolution and responsible gaming monitoring purposes.
• Support communication records: Retained for two (2) years following the closure of the relevant support case.
• Technical and device data (server logs): Retained for up to ninety (90) days, after which they are automatically deleted or anonymised.

At the end of each applicable retention period, your data is securely deleted or anonymised so that it can no longer be associated with you as an individual.

bigtka implements a comprehensive range of technical and organisational security measures to protect your personal data against unauthorised access, accidental loss, alteration, or disclosure. These measures include:

• 256-bit SSL/TLS encryption for all data transmitted between your device and bigtka servers.
• Encrypted storage of sensitive data at rest, including KYC documents and financial records.
• Access controls restricting access to personal data to authorised personnel only, on a need-to-know basis.
• Regular security audits and penetration testing of Platform infrastructure.
• Fraud detection systems that monitor for unusual account activity and flag potential security threats in real time.
• Tokenisation of payment account references so that full payment credentials are never stored on bigtka servers.

While bigtka takes every reasonable precaution to protect your data, no online system can guarantee absolute security. You play an important role in keeping your account secure by using a strong, unique password, not sharing your login credentials, and logging out of your account when using shared devices. If you suspect unauthorised access to your bigtka account, please contact our support team immediately via live chat.

As a bigtka player, you have the following rights with respect to your personal data. To exercise any of these rights, please contact our support team via the channels listed in Section 13.

• Right of access: You may request a copy of the personal data bigtka holds about you, along with information about how it is being used.
• Right to rectification: You may request that inaccurate or incomplete personal data be corrected or updated. You can update most account details directly from within your account dashboard.
• Right to erasure: You may request that bigtka delete your personal data where it is no longer necessary for the purposes for which it was collected, subject to our legal retention obligations.
• Right to restrict processing: You may request that bigtka limit the processing of your personal data in certain circumstances — for example, while a data accuracy dispute is being resolved.
• Right to data portability: You may request that bigtka provide your personal data in a structured, machine-readable format so that it can be transferred to another service provider.
• Right to withdraw consent: Where processing is based on your consent (such as marketing communications or non-essential cookies), you may withdraw that consent at any time without affecting the lawfulness of prior processing.
• Right to object: You may object to the processing of your data where bigtka relies on legitimate interests as the legal basis, subject to bigtka's overriding legitimate grounds.

bigtka will respond to all data rights requests within a reasonable timeframe and in accordance with applicable data protection law. In some cases, bigtka may need to verify your identity before processing a request, to ensure that data is not disclosed to or deleted at the request of an unauthorised party.

The bigtka Platform is strictly intended for adults aged 18 years and above. bigtka does not knowingly collect personal data from individuals under the age of 18. If you are a parent or guardian and believe that a minor has registered for a bigtka account or provided personal information to bigtka, please contact our support team immediately. Upon verification, bigtka will promptly close the account and delete all associated personal data.

bigtka takes its 18+ age restriction extremely seriously and employs age verification procedures during the registration process and as part of ongoing KYC compliance to prevent underage access to the Platform.

The bigtka Platform may contain references to third-party payment providers (such as bKash and Nagad) and game studio partners. Where you interact with these third parties' own platforms or services, their respective privacy policies will apply. bigtka is not responsible for the data practices of third-party platforms and encourages you to review their privacy policies before providing personal information to them. bigtka does not include external third-party links on its website other than those necessary to facilitate payments and game delivery.

bigtka reserves the right to update or amend this Privacy Policy at any time to reflect changes in our data practices, legal obligations, or Platform features. When we make material changes, we will notify registered players via email or through an in-Platform notification, and we will update the "Last Updated" date at the top of this page.

Your continued use of the bigtka Platform following the effective date of any updated Privacy Policy constitutes your acknowledgement of the changes. If you do not agree with the updated Policy, you should cease using the Platform and may request account closure in accordance with our Terms & Conditions.
