White Fin โ Offline Phishing & Scam Checker ๐ฆ
Scams are everywhere โ fake bank texts, "your parcel is on hold", "you've won", "verify your account now". They're designed to make you panic and act before you think. White Fin gives you a calm second opinion, instantly, and completely offline.
โโโโโโโโโโโโโโโโโโ
WHAT IT DOES
Paste any suspicious message (SMS, email, WhatsApp, anything) โ or click a built-in demo โ and in one click you get:
โข A clear verdict: High risk / Suspicious / No clear signs
โข The red flags highlighted right inside your message
โข The scam type: fake bank, delivery, crypto, gift card, refund/callback, prize, government impersonation, account takeover, and more
โข "How this scam works" โ so you learn to spot the next one
โข Your safe next step
โโโโโโโโโโโโโโโโโโ
HOW IT WORKS
White Fin reads the text on your computer and checks it against built-in knowledge of the world's ~50 most-impersonated brands and dozens of scam patterns: look-alike links, pressure wording, requests for passwords/codes/card details, dangerous attachment names, and more. It never tells you a message is "safe" โ only flags danger or tells you to verify yourself. No AI in the cloud, no online guessing โ just fast, local checks.
โโโโโโโโโโโโโโโโโโ
WHY I BUILT IT
Scams hit the people we love most โ parents, grandparents, anyone in a rushed moment. Most "scam checkers" want your email, an account, or upload your private messages to a server. I wanted the opposite: a tool that helps you, teaches you, and respects your privacy completely.
โโโโโโโโโโโโโโโโโโ
PRIVACY โ THE CORE PROMISE
๐ 100% offline โ no internet connection is ever used
๐ No account, no cloud, no tracking
๐ Nothing is stored โ your messages never leave your computer
Don't take my word for it: disconnect your internet and it works exactly the same.
โโโโโโโโโโโโโโโโโโ
ABOUT THE NAME
A white shark's fin cutting the surface โ a quiet guardian watching the water, spotting danger before it reaches you.

NO DIGITAL SIGNATURE โ AND HOW TO VERIFY YOU CAN TRUST IT (BEING HONEST)
I'm a solo indie developer releasing this for free. Code-signing certificates cost a yearly fee I'm not paying yet โ so Windows may show an "unknown publisher" warning. That's exactly why I'm giving you a way to verify the file yourself:
This file's unique ID (SHA-256 hash):
184a6d78cc7cfaae3fc0b5b43115f15a346ac5e7960fd7a2d0dfbfc163041ed4
Go to virustotal.com, paste that hash (or upload the file), and check it yourself. You'll see about 1 out of 70 engines flag it โ that single hit is a false positive (a generic, automated guess from one small engine, common for unsigned apps). Every major engine โ Microsoft, BitDefender, Kaspersky, Avast, ESET, CrowdStrike โ reports it CLEAN, and the behavior report shows ZERO network activity. Transparency matters to me more than looking polished.
(Note: this hash matches this exact version of the file. If you downloaded it here, it's the right one.)

HOW TO USE
1. Download and double-click โ no installation
2. Paste a suspicious message, or click a demo
3. Press Check

HONEST LIMITS
โข Windows only (for now).
โข White Fin is an educational aid โ it can't catch every scam and is never a confirmation that a message is safe. When in doubt, always contact the company directly using details you find yourself.

โข "No clear signs" is NOT a confirmation that a message is safe or legitimate.
โข It does not open links, scan files, or protect your device โ it only reviews the text you paste.
โข Drag a file in โ White Fin checks its NAME for dangerous or disguised types (like invoice.pdf.exe, .scr, .js, .iso). It never opens the file or scans its contents โ it only inspects the name, fully offline.
