tk1921 Privacy Policy

1. Data We Collect

tk1921 collects personal data in several ways: directly from you during registration and ongoing platform use, automatically through your device and browser when you interact with the site, and occasionally from third-party verification partners during our Know Your Customer (KYC) process.

1.1 Registration and Account Data

When you create a tk1921 account, we collect the following information:

• Full legal name as it appears on your government-issued identity document.
• Date of birth, used to verify that you meet the 18+ age requirement.
• Residential address, including city (Dhaka, Chittagong, Sylhet, Khulna, Rajshahi, or elsewhere in Bangladesh) and postal code.
• Email address, used for account communications, security alerts, and promotional messages where you have opted in.
• Mobile phone number, used for two-factor authentication and support communications.
• Username and a securely hashed version of your password — tk1921 never stores passwords in plain text.

1.2 Identity Verification (KYC) Documents

To comply with anti-money-laundering obligations and to verify player age and identity, we may request:

• A copy of a government-issued photo ID (National Identity Card, passport, or driving licence).
• Proof of residential address (utility bill, bank statement, or official correspondence dated within three months).
• Proof of ownership of the payment method used (e.g., a screenshot confirming that the bKash, Nagad, Rocket, or Upay account is registered in your name).

KYC documents are processed securely and are retained only for as long as required by our data retention obligations. Copies are not shared with any party other than our authorised verification partners.

1.3 Financial Transaction Data

When you make a deposit or withdrawal, we record transaction details including the payment method used, the transaction amount in BDT (৳), the date and time of the transaction, and the transaction reference number provided by the payment provider. tk1921 does not store full card numbers or mobile banking PINs — payment credentials are handled directly by the relevant payment provider.

1.4 Gameplay and Behavioural Data

We collect data about how you interact with the tk1921 platform, including the games you play, wager amounts, session duration, betting history, bonus usage, and responsible gaming tool activity (such as deposit limit adjustments or self-exclusion requests). This data is used to personalise your experience, detect problematic gambling patterns, and maintain fair-play standards.

1.5 Technical and Device Data

When you access tk1921, our servers automatically collect certain technical data:

• IP address and approximate geographic location (country and city level).
• Browser type, version, and language settings.
• Device type (mobile, tablet, or desktop) and operating system.
• Pages visited, time spent on each page, and clickstream data.
• Referring website or search engine (if you arrived via a search result or external link).

This technical data is used for security monitoring, fraud detection, performance optimisation, and aggregate analytics. It is not linked to your personal identity unless a security investigation requires it.

2. How We Use Your Data

tk1921 processes your personal data only where we have a lawful basis to do so. The following table summarises the primary purposes for which we use your data and the legal basis for each:

tk1921 does not use automated decision-making or profiling in a way that produces legal or similarly significant effects on players without human review. Where automated systems flag an account for review (for example, due to suspected fraud or responsible gaming concerns), the matter is assessed by a member of the tk1921 team before any account action is taken.

3. Data Sharing & Disclosure

tk1921 does not sell, rent, or trade your personal data. We share your information only in the following limited and controlled circumstances:

3.1 Payment Service Providers

To process deposits and withdrawals, we share necessary transaction data with payment providers including bKash, Nagad, Rocket, Upay, and card-processing partners for Visa and Mastercard transactions. These providers receive only the data required to execute the specific transaction and are bound by their own privacy and security obligations.

3.2 Identity Verification Partners

Where we use a third-party KYC or age-verification service to assist with document checks, that provider receives the documents you submit for the sole purpose of verification. Verification partners are contractually prohibited from using your data for any other purpose.

3.3 Fraud Prevention and Security Services

We may share limited technical data (such as IP addresses and device fingerprints) with fraud-prevention services to protect the platform and all players from abusive or criminal activity. This sharing is carried out on the basis of legitimate interest and is strictly controlled.

3.4 Legal and Regulatory Requirements

tk1921 may disclose personal data where required to do so by law, court order, or lawful request from a competent authority. In such cases we will disclose only the minimum data necessary to satisfy the legal requirement and, where permitted by law, will notify the affected player.

3.5 Business Transfers

In the event that tk1921 undergoes a merger, acquisition, or sale of all or part of its business, player data may be transferred to the acquiring entity as part of that transaction. Affected players will be notified in advance and the acquiring entity will be required to honour the commitments set out in this Privacy Policy.

4. Cookies & Tracking

tk1921 uses cookies and similar tracking technologies to operate the platform, maintain your login session, remember your preferences, and collect aggregate analytics data. The following categories of cookies are used:

• Strictly Necessary Cookies: These cookies are essential for the platform to function. They maintain your login session, protect against cross-site request forgery, and ensure that the cashier operates securely. These cookies cannot be disabled without breaking core platform functionality.
• Functional Cookies: These cookies remember your language preferences, display settings, and responsible gaming choices so that you do not have to reconfigure them on every visit.
• Analytics Cookies: We use anonymised analytics tools to understand how players navigate the tk1921 platform — which pages are most visited, where users encounter difficulties, and how session flows can be improved. Analytics data is aggregated and does not identify individual players.
• Security Cookies: Short-lived cookies used to detect and prevent fraudulent login attempts, bot activity, and account takeover attempts.

Most browsers allow you to control cookie behaviour through their settings. You may block or delete cookies at any time; however, disabling strictly necessary cookies will prevent you from logging in and using core platform features. tk1921 does not use third-party advertising or retargeting cookies.

5. Data Retention

tk1921 retains personal data only for as long as is necessary to fulfil the purposes for which it was collected, or as required by applicable legal, regulatory, or contractual obligations. Our standard retention periods are as follows:

• Active account data: Retained for the full duration of the account being open and active.
• KYC and identity documents: Retained for a minimum of five years from the date of account closure, in line with anti-money-laundering record-keeping requirements.
• Financial transaction records: Retained for a minimum of five years from the date of each transaction.
• Gameplay and betting history: Retained for five years from the date of each session or wager.
• Support communications: Retained for three years from the date of the last communication in a given support thread.
• Technical and device logs: Retained for 12 months, after which they are deleted or permanently anonymised.
• Marketing preferences and opt-in records: Retained for the duration of your consent, or until you withdraw consent, whichever is earlier.

When a retention period expires, personal data is securely deleted or irreversibly anonymised. Anonymised, aggregated data may be retained indefinitely for statistical and business intelligence purposes, as it can no longer be linked back to any individual.

6. Data Security

tk1921 implements a layered approach to data security, combining technical, organisational, and procedural controls to protect your personal information against unauthorised access, loss, alteration, or disclosure.

Technical safeguards in place include:

• TLS encryption for all data in transit between your browser or app and our servers.
• Encryption at rest for sensitive data fields including identity documents and payment method references.
• Password storage using strong one-way hashing algorithms — plain-text passwords are never stored.
• Firewall and intrusion detection systems monitoring network traffic around the clock.
• Rate limiting and brute-force protection on all login and authentication endpoints.
• Regular security audits and vulnerability assessments conducted by qualified security professionals.

Organisational safeguards include access controls that ensure only authorised tk1921 personnel can access personal data, and only to the extent required by their specific role. All staff with access to personal data receive training on data protection responsibilities.

7. Your Rights

As a player whose personal data is processed by tk1921, you hold the following rights in relation to your information. To exercise any of these rights, contact our support team using the plain-text email address provided in the footer of this page.

• Right of Access: You may request a copy of the personal data that tk1921 holds about you. We will respond within five business days of receiving a verified request.
• Right to Rectification: If any personal data we hold about you is inaccurate or incomplete, you have the right to request that we correct or complete it without undue delay.
• Right to Erasure: You may request that we delete your personal data where it is no longer necessary for the purpose for which it was collected, where you withdraw consent (and no other legal basis applies), or where the data has been processed unlawfully. Please note that certain data must be retained to meet our legal obligations (e.g., KYC records and transaction data) and cannot be erased on request.
• Right to Restrict Processing: In certain circumstances — for example, where you contest the accuracy of the data or object to our processing — you may request that we restrict how we use your data while a dispute is resolved.
• Right to Data Portability: Where we process your data on the basis of consent or contractual necessity, you may request a copy of that data in a structured, machine-readable format.
• Right to Withdraw Consent: Where we process your data on the basis of your consent (for example, for marketing communications), you may withdraw that consent at any time by updating your account preferences or contacting our support team. Withdrawal of consent does not affect the lawfulness of processing carried out before the withdrawal.
• Right to Object: You may object to our processing of your personal data where that processing is based on legitimate interest. We will assess your objection and cease processing unless we can demonstrate compelling legitimate grounds that override your interests.

tk1921 will not charge a fee for responding to data rights requests made in good faith. We may ask you to verify your identity before processing a request to ensure that data is not disclosed to an unauthorised party.

8. Policy Updates & Contact

tk1921 reviews this Privacy Policy periodically and may update it to reflect changes in our data practices, the services we offer, or applicable legal requirements. The effective date at the top of this page and in the hero section above will be updated whenever a revision is published.

Where a change to this policy is material — meaning it could significantly affect your rights or how we use your data — we will notify registered players by email before the change takes effect. For minor clarifications or formatting updates, the revised policy will be published on this page without individual notification.

We encourage you to review this Privacy Policy periodically to stay informed about how tk1921 protects your data. Continued use of the platform after a policy update takes effect constitutes your acknowledgment of the revised policy.
