ef666 takes a straightforward position on privacy — we collect only what we need to run your account, process your Nagad or Upay transactions and keep your session secure. What we hold, why we hold it and how you can act on it is set out clearly below. Access to this platform depends on your local law and eligible regions.
This notice describes how we collect, store and use personal information when you create an account, log in, or carry out a transaction through ef666. The information we collect falls into three broad categories: account identity details you submit when registering, transaction records generated when you use Nagad, Upay or another configured payment route, and technical session data such as device type, browser version and pages visited. We do not sell your personal information to third parties. We share data only where required to process a payment through a configured local route, to comply with a lawful request, or to protect the integrity of the platform. Your payment channel details — for example, the Nagad mobile number or Upay wallet reference you register — are stored in encrypted form and never exposed to other account holders. Retention periods vary by category: active account data is held while your account remains open, transaction logs are kept in line with applicable record-keeping requirements, and session logs are cleared on a rolling schedule. For accounts in Bangladesh, eligibility and data-handling obligations depend on the applicable local law and the eligible regions in which this platform operates. If you have a question about any specific category of data we hold, the contact route in the Support section below is the right place to start.
Not every interaction with ef666 falls under identical data rules. Understanding exactly which parts of your journey this policy governs — and where third-party terms take over — helps you make informed choices about how you share information. This section draws a clear line between what we own and control and what sits with an external provider.
Any action taken while you are logged into your ef666 account — reviewing your wallet balance, changing your contact number, or checking your transaction history — falls fully within this policy. We hold that data and you can request to review or correct it.
Deposits and withdrawals processed through Nagad or Upay generate records on both our system and the payment provider's system. This policy covers our copy of those records. The payment provider's own privacy terms govern what they retain on their side.
Pages you browse before logging in, game categories you view and content you read are captured as session data covered by this policy. We use this to understand how the site performs, not to build a profile tied to your personal identity before account creation.
Links to external payment portals, game studio environments or any off-platform resource operate under those services' own privacy terms. Once you leave ef666's domain, this policy no longer applies. Check the relevant third-party notice before submitting information on their pages.
Holding data is a responsibility we take seriously, and we want you to know exactly what you can do with the information we keep. You have a clear path to review your account records — log in and head to the account settings area, where your registered details, linked payment references and recent activity are visible. If something is wrong — a mistyped phone number, an outdated email address, an incorrect Nagad reference — you can update most fields directly in the account panel. For records you cannot change yourself, such as closed transaction logs or historical session data, you can raise a correction or deletion request through our support route. We aim to respond to every data request, and we will tell you if a specific record cannot be changed due to legal retention requirements. If you believe your data has been handled incorrectly, raise it with us directly before escalating to any external body. Availability of these rights depends on your local law and the eligible regions in which this platform operates.
Log in to your account and open the account settings page. Your registered identity details, linked payment references such as your Nagad number, and transaction history are displayed there for you to check at any time.
Most contact and payment details can be updated directly in account settings. If a field is locked — for example after a verification step — contact our support team with the corrected information and your account reference.
If you want to know specifically what we hold about you, or whether a particular record has been shared, send your question through the published support route. We will identify the relevant data category and respond clearly.
For deletion or restriction requests on data we are not legally required to retain, contact our team and quote your account number. We will confirm the scope of what can be actioned under applicable local law.
If something in this policy needs clarification or you need to act on a data request, use one of the routes below. We only list channels that are actually monitored — do not use social media or third-party forums for account data questions, as those are not secure routes for personal information.
The live chat widget is available on the ef666 website. Use it to raise a privacy question, flag an incorrect account detail or ask which records we hold for your account. Quote your registered account number when you connect.
Send your data request or privacy question to our published support email address. Include your account reference and a clear description of the record or issue. Email is the right route for formal data-correction or deletion requests.
The help section inside your logged-in account area covers common privacy and data questions with step-by-step explanations. Check there first — many record reviews and contact-detail updates can be completed without waiting for a support reply.
The way we store and protect your information reflects the nature of the data itself. Payment references linked to Nagad or Upay are encrypted at rest and in transit. Account passwords are hashed, not stored in readable form. We use session cookies to keep you logged in securely and to recognise your device between visits — you can manage cookie preferences through your browser settings, though disabling certain cookies may affect how account pages load.
Your Nagad mobile number or Upay wallet reference is stored in encrypted form. It is never displayed in full to other account holders or support staff, and it is transmitted only through secured payment routes during deposit and withdrawal processing.
We use functional cookies to maintain your login session and preference cookies to remember your account settings across visits. Tracking cookies from third-party analytics tools are limited to aggregate site-performance data only. Adjust preferences in your browser at any time.
Active account data is kept while your account is open. Transaction logs are retained in line with applicable record-keeping requirements. Session and browsing data is cleared on a rolling schedule. After account closure, residual data is held only as long as legally required.
To request a change to retained data or to ask about a specific record, contact our team through the published support route and quote your account number. We will confirm what can be actioned under your local law and the eligible regions this platform serves.
The questions below cover what we get asked most about data, account records, payment references and how to act on your rights. If your question is not here, use the support contact route listed above.
We collect the identity and contact details you provide during registration, your linked payment references such as a Nagad mobile number or Upay wallet ID, and technical session data like your device type and browser. We collect only what is needed to run your account and process transactions.
Yes. Your Nagad or Upay reference is stored encrypted and is never visible to other account holders. It is used only to route your deposit or withdrawal through the configured payment channel. Support staff access it only in masked form when handling a verified account query.
Log in and open the account settings area — your registered contact details, linked payment references and transaction history are displayed there. For records that are not shown in the account panel, contact our support team through live chat or email and quote your account number.
You can request deletion of data we are not legally required to retain. Contact our support team with your account number and a clear deletion request. We will confirm which records can be removed under applicable local law and the eligible regions this platform operates in. Some transaction logs must be kept for legal record-keeping purposes.
We share data only where necessary: with Nagad, Upay or other configured payment providers to process your transaction, or in response to a lawful request. We do not sell your personal information. Third-party payment providers operate under their own privacy terms for the data they hold.
Functional cookies keep your login session active and save your account preferences. Analytics cookies collect aggregate browsing data to help us improve the site. You can disable cookies in your browser settings at any time. Turning off functional cookies may affect how account pages load or keep you logged in.
