KleanBox: Spam SMS Blocker

KleanBox keeps your SMS inbox clean by sorting spam, promotions and other unwanted messages from unknown senders into their own folders. Filtering runs on your iPhone, and nothing leaves it unless you choose to share. SMART CATEGORIES Messages from unknown senders are sorted automatically: • Spam — betting, fake prizes, phishing and other junk • Promotions — marketing and campaign messages • Transactions — banking, delivery and account notifications • Personal — everything else reaches your inbox untouched Drag categories to decide which one wins when a message matches more than one. RULE PACKS Install curated rule collections with one tap: betting and gambling, loan offers, investment scams, fake prizes, institution phishing, delivery scams and retail campaigns. GUIDED RULE BUILDER Describe a rule in plain language — "starts with", "contains a link", "sender is a short code" — and KleanBox writes the pattern for you. Prefer full control? Keyword and regex rules are still there. MESSAGE TESTER Paste any message to see which folder it would land in and which rule or keyword decided that, before a real one arrives. SAFE SENDERS Keep your bank, your doctor or anyone you trust out of every filter, whatever the rules say. REPORT TO RULE Report a filtered message as junk right inside Messages. KleanBox picks it up and offers to turn it into a rule that catches the next one, whoever sends it. RULE HEALTH KleanBox flags rules that would filter ordinary messages, never run, or duplicate another rule. ALWAYS UP TO DATE Smart Filtering patterns refresh quietly in the background, so new spam wording is covered without waiting for an app update. Definitions cover English, Turkish, German and Spanish spam. ICLOUD SYNC Optionally keep your rules and safe senders the same on every device signed in to your iCloud account. Message content is never synced. PRIVACY FIRST Filtering happens on your device. KleanBox does not collect or store your messages. Two optional settings send data to help block campaigns for everyone, and both stay off until you turn them on — with no name, account or device identifier attached. EASY SETUP KleanBox guides you step by step through enabling message filtering in iOS Settings. No technical knowledge required. Built on Apple's official message filtering framework, with an interface in English and Turkish. Download KleanBox and enjoy a quieter inbox.
