Your messages never leave your iPhone. — ZERO-TRUST PRIVACY - 100% on-device processing - No cloud servers - Nothing to sign up for - Your data stays on your device FREE - On-device spam and scam detection - Custom keyword blocking - Protection against shortened and disguised phishing links - Automatic sorting into Transactions, Promotions and Junk - No ads, no data collection DEFNDR PRO - Advanced machine-learning detection for sophisticated scams - Adjustable sensitivity, from lenient to strict - Allow and block lists for senders you choose - Unlimited custom keywords - Detection for suspicious formatting, links and patterns - Custom theme studio with a gradient editor HOW IT WORKS Defndr plugs into iOS Message Filtering and runs silently in the background.
