At 527sf, we are straightforward about what data we collect from your account, how we use it, and the choices you have. This policy covers every interaction you have with us — from creating your account to making a deposit via Nagad or Bank Transfer — and applies to all eligible regions where access to 527sf is permitted under local law.
We collect information you provide directly — such as the name, email address and mobile number you enter when opening your 527sf account — as well as transactional context generated when you use payment routes like Nagad, Upay or Bank Transfer. We also collect technical data your device sends automatically: browser type, IP address, session duration and pages visited. This data helps us keep your account secure, process your transactions accurately and resolve support requests without asking you to repeat yourself. We do not sell your personal data to third parties. We share it only where necessary to process a payment, verify your account identity, or comply with a lawful request. Any data shared with a payment processor — for example, the reference generated during a Nagad transfer — is governed by that processor's own terms, which sit outside our direct control. Access to 527sf and the rights available to you under this policy depend on your local law and eligible region. We aim to keep this policy current; when we make a meaningful change, we will update the version date at the bottom of this page. Continuing to use your account after a posted change means you have read and understood the updated terms.
Not every data interaction you have while using 527sf falls under this single policy. Understanding the boundaries helps you know who to contact when something needs attention. The four areas below define what this policy governs and what sits outside it, so you can direct any question to the right place without confusion.
This policy fully covers data collected when you register, log in, update your profile or contact our support team. Every record tied to your 527sf account identity — email, mobile number, session history — falls within our direct data responsibility.
Deposit and withdrawal records generated through Nagad, Upay or Bank Transfer are covered here to the extent we hold them. The data handled directly by those payment processors is governed by their own privacy terms, not ours, and we do not control it.
Cookies and similar tracking tools that operate on 527sf pages are covered by this policy. We use them to remember your login state and to understand how you navigate the site. You can manage cookie preferences through your browser settings at any time.
Links or integrations that take you away from 527sf — such as an external payment gateway page or a third-party identity check — fall outside this policy. We are not responsible for the data practices of those external services once you leave our domain.
Your account gives you several concrete options for managing your own information. These are not abstract promises — each one has a specific path inside your 527sf account or through our support channel. To review what data we hold, log in and open the account settings page. Your registered name, email, mobile number and linked payment references are visible there. If any detail is incorrect — for example, a mobile number associated with your Nagad wallet — you can submit a correction request directly from that page or through our support route. If you want to understand why a specific piece of data was collected or how long we keep it, raise a question via the support channel listed in the contact section below. We will respond with the specific retention reason and period for the data type you ask about. Eligibility for certain rights may vary depending on your local law and the region from which you access 527sf.
Log in to your account and open the settings page to see your registered contact details, linked payment references and recent session history stored against your profile.
If your name, email or mobile number is wrong — including the number tied to a Nagad or Upay wallet — use the edit fields in account settings or contact support to submit a verified correction.
Send a question through our support channel naming the specific data type you want explained. We will tell you the purpose, the legal basis where applicable and how long that data is kept under our standard retention schedule.
If you believe data is being held incorrectly or you want to understand deletion options available in your eligible region, contact support with your account reference. We will confirm what steps are open to you under current policy.
If a section of this policy raises a question you cannot answer by reading it, or if you need to take action on your data, use one of the routes below. We publish only the channels that are active and monitored — we do not list a route that is not operational.
Open the chat widget on any 527sf page while logged in. State your account email and the specific privacy question or data request. The agent can raise a formal record on your behalf.
Send your query to the support email address shown in the Contact section of your account dashboard. Include your registered mobile number and a clear description of the data request you are making.
The Help Centre accessible from your signed-in account menu contains a dedicated privacy and data section. You can submit a formal data question there and track its status from the same panel.
We apply consistent data handling across every account interaction — from the moment you enter your email at login through every Nagad deposit reference we process. This section explains the four key areas of how we manage data in practice, so you know what to expect rather than having to guess.
We keep your account data for as long as your account remains active and for a further period required to resolve any outstanding transaction queries. When a retention period ends, data is deleted or anonymised according to our internal schedule. You can ask us for the specific period that applies to your account type.
We use session cookies to keep you logged in and analytical cookies to understand page navigation patterns. No cookie on 527sf is used to build an advertising profile sold to a third party. You can clear or block cookies through your browser settings; doing so may affect login persistence on mobile.
Access to your stored account data is restricted to authenticated staff with a documented reason to view it. Your account password is stored in a hashed form — we cannot read it in plain text. If you suspect unauthorised access, change your password immediately and contact support with your account reference.
When this policy changes in a way that affects your rights or our data practices, we update the version date visible at the bottom of this page. For significant changes we will also notify you via the contact method registered to your account. Availability of certain rights depends on your local law and eligible region.
These are the questions we hear most often about how 527sf handles data. Each answer is specific to this policy — not a generic response about the platform as a whole.
We collect the name, email address and mobile number you enter at registration. If you make a deposit via Nagad or Bank Transfer, we also store the transaction reference generated by that payment. Technical data such as your IP address and browser type is logged automatically during each session.
We pass only the minimum data needed to process your specific transaction — typically your account reference and the requested amount. Nagad and Upay then handle that data under their own privacy terms. We do not share your full account profile with any payment processor beyond what the transaction requires.
We retain account data for a period after your last activity to cover any outstanding transaction queries or legal obligations that apply in your eligible region. The exact period depends on the data type. Contact support with your account reference and we will confirm the retention period that applies to you.
Yes. Log in and use the account settings page to correct contact details like your registered mobile number. For a removal or deletion request, send a message through the support channel with your account email and a description of the data you want addressed. Availability depends on your local law and eligible region.
Your account settings page shows your registered profile details and linked payment references. For a fuller picture — including session logs or support correspondence — raise a data access request via live chat or the email route listed in your account dashboard. We will confirm what records we hold within a reasonable time.
We use session cookies to maintain your login state and analytical cookies to understand how the site is navigated. You can block or clear cookies through your browser settings at any time. Note that blocking session cookies will affect how login works on mobile and may require you to sign in again each visit.
