Before you click.
Before you pay.
Know what you're dealing with.
SecWarn helps you spot suspicious messages, links, UPI IDs and scam patterns on Android before they catch you off guard.
"Urgent: Electricity bill ₹4,890 unpaid. Power will be cut at 9:30 PM. Click link to verify: bit.ly/discom-pay"
Suspicious Payment Link Detected
This message creates fake urgency using a shortened link and an unverified personal phone number. Electricity providers never use personal links.
Real-time defense telemetry
Our local heuristics run continuously on Android without offloading your private communications to cloud servers.
On-device heuristics evaluate threats before you can tap.
100% on-device execution with zero server processing delay.
Chats, SMS text, and passwords never leave your device.
Known malicious domains, UPI schemes, and APK hashes.
Scams don't always look like scams
Fraudsters don't try to break your phone's code. They construct convincing, high-pressure situations designed to catch you off guard during everyday tasks.
Fake Courier update
Arrives when you're genuinely expecting an online package. The link tries to download a rogue courier .apk that intercepts bank OTPs.
Fake Overdue Electricity Bill
Creates manufactured panic during evening hours. Victims are coerced into calling a fraudster's personal WhatsApp number and making urgent payments.
Urgency / Bank KYC Alert
Mimics official bank security notices. Directs you to a cloned net-banking portal where your account passwords and UPI credentials are harvested.
See SecWarn in action
Switch between common deceptive scenarios to see how SecWarn’s on-device heuristics detect threats, inspect flags, and explain risks in under 15ms.
Rogue APK Installer Detected
Unverified shortened domain + false parcel return urgency. The link attempts an unauthorized direct Android APK installation mimicking national postal logistics.
Engineered for everyday peace of mind
Four specialized protection layers designed to run unobtrusively on Android — giving you speed, accuracy, and absolute privacy.
On-Device Screen & Message Shield
Analyzes visible text in supported browsers and messaging apps to spot deceptive links and scam patterns before you tap. Hardcoded Android accessibility restrictions guarantee that password inputs, PIN fields, and financial apps are never read.
UPI & Payment Verification
Spots manipulated UPI collect requests, unverified VPA handles, and inverted transaction traps where fraudsters try to convince you to enter your UPI PIN to "receive" funds.
Reminds you instantly: Your UPI PIN is strictly for debiting your account, never for receiving money.
QR Code Stream Scanner
Real-time camera frame threat check inspects embedded links, UPI mandates, and rogue APK payloads in physical merchant flyers, courier stickers, and parking meters before opening them.
Privacy-First Architecture
100% local heuristic engine runs directly on your Android phone. Banking, payment, healthcare, and password manager apps are permanently excluded from inspection by strict system policy. Personal inbox contents never leave your device.
A Second Opinion Before You Act
SecWarn works quietly in the background on your Android phone, stepping forward only in the exact moment a high-risk trap appears.
Threat Arrives
A deceptive SMS notification, shortened link, urgent WhatsApp text, or unexpected UPI collect request pops up while you're busy multitasking.
"Electricity power disconnected tonight at 9:30 PM. Pay via link..."
Heuristic Analysis
SecWarn's local engine inspects URL patterns, sender legitimacy, UPI directions, and psychological pressure tactics in under 15ms completely on-device.
Calm Warning
A clean advisory sheet explains the specific risk before you click, install an unknown APK, or enter a payment PIN. You make the final decision with clarity.
"Avoid Link: State electricity providers never use shortened personal links."
