Defndr uses Core ML to analyze SMS patterns locally on your device. No messages are ever transmitted to external servers. The ML model runs entirely offline, ensuring complete privacy.
Filtered messages are automatically moved to your Junk folder. You can review them anytime and mark false positives. The system learns from your corrections to improve accuracy.
Defndr filters SMS and MMS messages. iMessage has built-in spam protection from Apple. This app focuses on traditional text message spam that bypasses iMessage.
