About this app

Nomorobo’s award-winning technology is now built for text messages and helps filter spam and scam SMS and MMS from unknown senders, so you spend less time dealing with junk and risky links. Stay focused on real conversations while suspected spam gets filtered out before it distracts you. KEY FEATURES • Filter spam and scam texts from unknown senders • Reduce distractions from promotional and fraudulent messages • Simple setup in a few steps • Built with Nomorobo’s 10+ years experience fighting unwanted communications HOW IT WORKS Spam Text Blocker runs as an iOS Message Filter. • The initial filtering happens on your device. • For some messages, iOS sends a non-identifying request through Apple’s message filtering services to help determine whether a message looks like spam. • We never receive info that directly identifies you (like your phone number, Apple ID, or contacts). • The result is used only to classify messages as junk or allowed. PRIVACY We’re built for spam protection, not data collection. Spam Text Blocker filters on-device and may use Apple’s message filtering services to send a non-identifying request to Nomorobo’s servers for classification. We do not receive your phone number, contacts, or any other information that directly identifies you. Data is used only to provide and improve spam filtering.
