At 4 bit, every piece of your personal information is handled with the utmost care. On this page, we're being fully transparent — what data we collect, why we collect it, and how it stays secure. No hidden agenda.
Your privacy is ensured through a combination of technology and policy
Every transaction and piece of data on 4 bit is encrypted using 256-bit SSL/TLS protocols. No hacker or third party can access your information.
4 bit collects only the information strictly necessary to provide our services. Collecting excessive or unnecessary data goes against our core principles.
Your name, mobile number, transaction history — 4 bit sells none of it. No data is passed to advertisers or data brokers.
4 bit's systems are independently audited by a third party every three months. Any vulnerabilities identified are addressed promptly.
4 bit complies with European GDPR standards — meaning we obtain your consent and you can request deletion of your data at any time.
Enable two-factor authentication when logging in to 4 bit. Even if your password is compromised, your account stays protected.
By using any 4 bit service, you are deemed to have accepted this Privacy Policy. Users under the age of 18 are not permitted to use our services.
The first question many people ask about 4 bit is — "Is my data safe?" It's a smart question. Online data security is a genuinely important concern.
4 bit takes this matter very seriously. We believe that when you trust us enough to create an account, protecting your data is our ethical responsibility — not merely a legal obligation.
We've written this policy in plain, straightforward English — not dense legal language — so you can clearly understand exactly what happens with your data.
Only the information that's necessary — nothing more
4 bit collects three types of information — what you provide directly, what is collected automatically from your device, and what is required at the time of a transaction.
| Data Type | When it's collected | Why It's Needed |
|---|---|---|
| Mobile number | At registration | Account verification & payments |
| Name & date of birth | During KYC verification | To verify your age and identity |
| Email address | Upon optional registration | To send important notifications |
| National ID card | For high-value withdrawals | For identity verification & AML compliance |
| BKash/Nagad number | During payment setup | During deposit and withdrawal processing |
Please note: 4 bit never stores your password in plain text. All passwords are encrypted using bcrypt hashing.
For service delivery & improvement only
4 bit uses your data for one primary purpose — to provide you with a better experience. It is never used for anything beyond that.
You can opt out of promotional communications at any time. Contact Support or opt out directly from your account settings.
4 bit never shares your information with marketing companies, advertisers, or data brokers. This policy will not change under any circumstances.
In a limited and controlled scope
Access to your data at 4 bit is strictly limited. Your information is shared only in the following circumstances:
Selected third parties for payment processing (bKash, Nagad), technology services, and security verification — all held to the same privacy standards as 4 bit.
Data may be disclosed in response to a valid court order or regulatory authority request. In such cases, 4 bit will endeavour to notify you in advance, unless prohibited by law from doing so.
What cookies are and how they're used
Cookies are small text files stored in your browser. 4 bit uses cookies to enhance your experience.
You can disable cookies through your browser settings, though doing so may cause some features to not work properly.
No more than necessary, no less than the law requires
4 bit retains your data only for as long as necessary. Data is held while your account remains active. Following account closure, transaction records are generally kept for up to 5 years in accordance with legal obligations.
After the retention period, data is securely deleted or anonymised.

You may request to see what information 4 bit holds about you. It will be provided within 30 days.

After closing your account, you may request deletion of your data — within the bounds of legal requirements.
You may request that your data not be used for a specific purpose.
You may request a copy of your data in a standard format (CSV/JSON).
You may object to marketing communications or automated decision-making.
