SmishAlert protects your iPhone from smishing: phishing attacks delivered by text message and iMessage. Enable Apple's built-in Message Filtering and let SmishAlert's on-device model, trained on thousands of known threats, catch suspicious messages before you tap a link. WHY SMISHING MATTERS Text-message phishing ("smishing") is one of the fastest-growing attack vectors. Unlike email, SMS and iMessage sit outside traditional corporate security tools. SmishAlert gives you a personal defense layer right on your iPhone. HOW IT WORKS 1. Enable SmishAlert as your Message Filter in iOS Settings 2. SmishAlert analyzes incoming messages on your device using our highly trained model 3. Suspicious messages are filtered into Spam, so you stay protected without reading every text 4. Report anything suspicious with one tap from the share sheet, a screenshot, or the in-message Report Junk button TWO PLANS: CHOOSE YOUR PRIVACY LEVEL Personal • On-device SMS and iMessage filtering • User-initiated reporting • Nothing leaves your device automatically Unknown Guard • Everything in Personal • Automatically screens messages from unknown senders • Link checks and verdicts for numbers not in your contacts • Privacy-first: no user identity attached on personal plans Without a subscription, message filtering is not active. You may submit one free report to try the reporting flow. Subscriptions auto-renew unless canceled at least 24 hours before the end of the current period. Your Apple ID is charged for renewal within 24 hours before the current period ends. You can manage or cancel anytime in your App Store account settings. PRIVACY BY DESIGN SmishAlert is built for people who want real protection without giving up their privacy. The Personal plan keeps all analysis on your iPhone. The Unknown Guard plan uses privacy-preserving techniques: messages are converted to coded fingerprints for correlation at the sender and content level only. Contacts are never included in unknown-sender screening. Learn more: https://www.smishalert.ai/trust SIGN IN Sign in with Apple, Google, or Microsoft to sync your account and alerts across devices.
