Swadhin Bangla AI Security
AI-Powered Threat Detection & Prevention for Android
AI-powered antivirus and anti-malware for Bangladesh: real-time detection and prevention of malware, phishing, smishing, ransomware and fake apps — with safety alerts for bKash, Nagad, Rocket, Upay, online banking, merchant and mobile-operator (telco) app users. It also blocks trackers and harmful websites, saving your mobile data, and shows you how much Taka that is worth.
Why Swadhin Bangla
Built for Bangladeshi users and the threats they actually face — mobile-financial-service scams, smishing links and fake apps from outside Google Play.
- Saves mobile data — and shows the Taka. See how many MB the app has saved you and what that is worth on mobile data.
- Works everywhere you go. Protects you on Wi-Fi and mobile data, even on slow 2G/3G connections outside the cities.
- Built for the apps that hold your money. Scam reminders and fake-app warnings for bKash, Nagad, Rocket, Upay, online banking, merchant and telco apps.
- Made in Bangladesh. By a Bangladeshi cybersecurity company, in Bangla and English.
For Android phones and tablets (Android 7.0 and later). Also written as Shadhin Bangla, Sadhin Bangla, Swadin Bangla — by Fred Intelligence Limited.
AI-powered detection & prevention
Swadhin Bangla does not wait for an attack to happen. It detects threats early and stops them before they reach you.
Detection
- Analyses apps, files, links, SMS and websites against continuously updated threat intelligence
- Smart matching spots fake look-alike apps and phishing pages that imitate bKash, Nagad, banks, merchants, mobile operators and other trusted brands
- Deeper scan for apps installed from outside Google Play
- Ransomware early-warning from decoy files
Prevention
- Blocks phishing, malware and tracking domains before they load — in every app
- Warns you before you tap a dangerous SMS link or open a phishing site in Chrome
- Reminds you never to share your PIN or OTP when a payment app opens right after a call
- Locks private apps and keeps private files in an encrypted vault
Saves your mobile data & money
Every tracker and harmful website the app blocks is data your phone never has to download.
Money Saved on Mobile Data
The Protection Summary turns the mobile data you saved into an estimated Taka amount, based on typical Bangladeshi data-pack prices. Only data saved on mobile data is counted in Taka.
Data Saved (MB)
See how many megabytes were saved because trackers, harmful websites and other unwanted content were stopped before they loaded.
Works on Slow Networks
Protection keeps working on mobile data, including slow 2G/3G connections in villages and small towns, and stays on when you switch between Wi-Fi and mobile data.
Taka and MB figures are estimates. Actual savings depend on the websites you visit and your data pack.
Scan & real-time protection
Finds threats on your phone and stops new ones as they arrive.
Antivirus & Anti-Malware Scan
Checks every installed app for malware, fake apps and suspicious behaviour. Apps from outside Google Play get a deeper scan on our security service.
Real-Time Protection
Newly installed apps are checked automatically, so a dangerous app is flagged as soon as it arrives.
File Scanner
Checks files, photos, videos and downloaded APKs using a secure digital fingerprint — your photos, videos and documents never leave your phone.
Ransomware Early Warning
Watches decoy files and alerts you if they are suddenly changed, renamed or deleted — an early sign of ransomware.
Fake App Detection
Spots apps that pretend to be bKash, Nagad, banks, merchant apps, mobile operators or other trusted brands by checking each app's package name and signing certificate against a registry of official apps.
Automatic Threat Updates
New, digitally signed threat data arrives automatically throughout the day — your protection stays current without waiting for an app update.
Web & scam protection
Stops phishing and scam links before you open them.
Web Protection
Blocks phishing and malware websites in every app, on Wi-Fi and mobile data. It runs as a filter on your own phone: there is no remote VPN server, your IP address does not change, and HTTPS is never decrypted.
Tracker & Privacy Protection
An optional filter that blocks known tracking and harmful domains in real time. Only domain names are checked — never full web addresses or page content.
Smishing (SMS Link) Warning
Detects dangerous links in SMS notifications and warns you before you tap them.
Browser Protection
Checks the website address in Chrome's address bar against our threat-intelligence feed and warns you about phishing sites.
Custom Block / Allow List
Block any website you choose, or always allow a site you trust.
Number Check
Paste a suspicious phone number to check it against our security service before you call back.
MFS, banking, merchant & telco app safety
Protection for the apps that hold your money.
Payment Protection
Warnings against fake apps, phishing pages and phone scams for users of bKash, Nagad, Rocket, Upay and online banking apps.
Payment Safety Alert
If a payment or banking app is opened right after a phone call, the app reminds you: never share your PIN or OTP. It never reads your transaction details.
Merchant & Telco Apps
Fake-app and phishing protection also covers merchant / shopping apps and mobile-operator (telco) apps. Choose which payment, banking and merchant apps to protect — they keep working normally while you are protected.
Privacy tools
Keep your private apps, files and accounts safe.
App Lock
Lock chosen apps behind a PIN or fingerprint.
Private Vault
Keep private photos, videos and files in an encrypted vault that stays only on your device.
Privacy Protection
See which apps on your phone can access sensitive permissions, and review them in one place.
Password Leak Check
Check whether a password has appeared in known data breaches.
Wi-Fi Security Scan
Warns you about insecure or spoofed Wi-Fi networks. Android asks for location permission only so the app can read Wi-Fi details — your location is never tracked.
Security Advice
Checks your phone's security settings and tells you what to fix, in plain language.
