## What is KleanBox?

KleanBox keeps your SMS inbox clean by filtering out spam, promotions, and unwanted messages from unknown senders — all without ever leaving your device.

SMART CATEGORIZATION
Messages are automatically sorted into four clear categories:
• Spam — Fraudulent and junk messages
• Promotions — Marketing and advertising
• Transactions — Banking and payment notifications
• Personal — Everything else passes through

CUSTOM RULES
Create your own filtering rules using keywords or regex patterns. Match against sender numbers, message content, or both. Enable, disable, or fine-tune rules anytime.

SMART FILTERING
Community-maintained filter definitions classify messages automatically when your custom rules don't match. Smart Filtering learns from thousands of known spam patterns.

PRIVACY FIRST
All filtering happens entirely on your device. Your messages are never sent to any server. No data collection. No tracking. No compromises.

EASY SETUP
Get started in under a minute. KleanBox guides you step-by-step through enabling message filtering in iOS Settings — no technical knowledge required.

DESIGNED FOR YOU
Works seamlessly with the Messages app using Apple's official message filtering framework.

Download KleanBox and enjoy a cleaner, quieter inbox.
