## Description

Stop spam before it reaches you. Defndr blocks scam and phishing texts and sorts the rest into folders — all on-device. No cloud, no tracking, no ads.

Defndr is an SMS firewall that stops spam before it reaches you.

On-device machine learning checks every message from unknown senders, blocks phishing and scams, and quietly sorts the rest into the right folder — without sending anything anywhere. Your messages never leave your iPhone.
