Your privacy matters at 399det. This Privacy Policy explains precisely what personal data we collect from players in Bangladesh, why we collect it, how we use and store it, and what rights you have over your own information.
These principles shape every data decision we make. They summarise — but do not replace — the full Privacy Policy text below.
399det will never sell, rent, or trade your personal data to third parties for their own marketing or commercial purposes. Your information is used solely to operate and improve your experience on the 399det platform.
Every connection between your device and the 399det platform is protected by industry-standard 256-bit SSL encryption — the same standard used by major Bangladeshi banks. Your credentials and payment data travel encrypted at all times.
We collect only the data that is genuinely necessary to provide the 399det service, verify your identity, process your transactions in BDT, and comply with applicable legal obligations. We do not collect data speculatively.
Personal data is not held indefinitely. 399det applies defined retention periods to each category of data. When data is no longer required for the purpose for which it was collected, it is securely deleted or anonymised.
You have the right to access, correct, and in certain circumstances request deletion of your personal data. Requests can be submitted at any time via the support team at [email protected] and will be processed promptly.
Promotional communications from 399det are entirely opt-in. If you no longer wish to receive marketing emails or messages, you may opt out at any time via your account settings or by contacting the support team directly.

All transactions on the 399det platform are conducted in Bangladeshi Taka (৳) via locally familiar payment methods including bKash, Nagad, Rocket, and Upay.
For all data-related enquiries, you may contact the 399det data team at [email protected]. We are committed to handling your personal data with transparency, care, and respect.
When you register a Player Account on 399det, make a deposit or withdrawal, contact the support team, or participate in a promotion, you provide us with personal data. This includes your full legal name, date of birth, email address, mobile number, residential address (including city and division within Bangladesh), national identity card (NID) number or passport number, and payment account details such as your registered bKash or Nagad mobile number.
When you access the 399det platform, certain technical data is collected automatically by our systems. This includes your IP address, device type, operating system, browser type and version, the pages you visit, the games you play, wager amounts, session start and end times, and clickstream data reflecting how you navigate the platform. This data is collected primarily for security monitoring, fraud detection, and platform performance optimisation.
In some circumstances, 399det may receive personal data about you from third parties. This includes identity verification data returned by KYC service providers, fraud risk scores from payment processing partners, and technical data from analytics providers. We only receive third-party data where it is necessary for the operation of the platform and where the third party is contractually bound to share data lawfully.
399det collects personal data through the following channels:
399det processes your personal data for the following purposes:
399det shares personal data with carefully selected third-party service providers who assist in operating the platform. These include KYC and identity verification providers, payment processing partners (including operators of bKash, Nagad, and card networks), game software providers such as Pragmatic Play, Evolution Gaming, and Spribe, cloud hosting and infrastructure providers, and customer support tooling providers. All service providers are bound by contractual data processing agreements that restrict their use of your data to the specific service they provide.
399det may disclose personal data to law enforcement agencies, regulatory bodies, or other competent authorities where required by applicable law or where we have a good-faith belief that disclosure is necessary to prevent fraud, protect the safety of players, or respond to a lawful legal process. We will notify you of such disclosure where we are legally permitted to do so.
399det does not sell, rent, exchange, or otherwise transfer your personal data to any third party for that party's own marketing, advertising, or commercial use. This prohibition applies unconditionally and is not subject to any exception.
The 399det platform uses cookies and similar tracking technologies to enhance platform functionality, maintain your session, remember your preferences, and collect anonymous usage analytics. The categories of cookies used are as follows:
You may manage your cookie preferences through your browser settings at any time. Disabling certain cookies may affect the functionality of the 399det platform.
399det retains personal data only for as long as necessary to fulfil the purpose for which it was collected, or as required by applicable legal or regulatory obligations. The following indicative retention periods apply:
When the applicable retention period expires, personal data is securely deleted from 399det systems or irreversibly anonymised so that it can no longer be associated with any individual.
399det implements a comprehensive set 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 encryption for all data transmitted between your device and our servers; strict role-based access controls limiting internal staff access to personal data on a need-to-know basis; regular security audits and penetration testing of the platform infrastructure; secure, encrypted storage of all KYC documents; and automated fraud detection systems that monitor for suspicious account activity in real time.
While 399det takes every reasonable precaution to safeguard your data, no system connected to the internet can be guaranteed to be entirely immune to security incidents. In the event of a data breach that poses a significant risk to your rights or interests, 399det will notify affected players promptly and take all reasonable steps to contain and remediate the incident.
As a player on the 399det platform, you have the following rights with respect to your personal data:
To exercise any of these rights, please contact the 399det support team at [email protected]. We will respond to all rights requests within thirty (30) calendar days. In complex cases, this period may be extended by a further thirty (30) days, in which case we will notify you of the extension and the reason for it.
The 399det platform is strictly restricted to individuals aged 18 years or older. We do not knowingly collect personal data from anyone under the age of 18. If we become aware that a Player Account has been registered by or on behalf of a minor, that account will be closed immediately, all bets will be voided, and any deposited funds will be returned to the payment method from which they originated. If you believe that a minor has accessed the 399det platform, please contact us immediately at [email protected].
The 399det platform does not contain links to third-party websites for commercial or affiliate purposes. Where third-party game software (from providers such as Pragmatic Play, Evolution Gaming, or Microgaming) is embedded within the platform, those providers operate under their own privacy policies in respect of any data they independently collect via their software interfaces. 399det is not responsible for the data practices of third-party game providers and encourages players to review those providers' own privacy documentation where relevant.
399det reserves the right to update or amend this Privacy Policy at any time. Where a material change is made to the way in which we collect or use your personal data, you will be notified via your registered email address or via an in-platform notification at least seven (7) calendar days before the change takes effect. The "Effective" date at the top of this document will be updated to reflect the date of the most recent revision. Continued use of the 399det platform after the effective date of any amendment constitutes your acceptance of the updated Privacy Policy.
If you have any questions, concerns, or requests relating to this Privacy Policy or to the way 399det handles your personal data, please contact us through any of the following channels:
We are committed to resolving any privacy-related concern promptly and transparently. If you remain dissatisfied after contacting us, you may have the right to lodge a complaint with the relevant data protection authority in your jurisdiction.
