Tired of spam texts? TextShield quietly sorts them out — the decision is made on your device, and your messages never leave your phone. HOW IT WORKS Texts from unknown senders pass through three checkpoints: 1. Your allow list (always wins, important texts are never lost) 2. Your block list (keywords, regex, sender prefixes) 3. Built-in rule packs for Chinese (170 rules) and Japanese (101 rules) spam patterns (loan scams, fake invoices, gambling, delivery & bank phishing) Anything unmatched is delivered normally — when in doubt, let it through. EVERYTHING IS FREE Unlimited rules, regex and sender-prefix rules, both built-in rule packs and the filter test bench are open to everyone. No paywall, no subscription. ABOUT THE ADS A single banner sits at the bottom of the home screen, served by Google AdMob. Fetching it is the app's only network activity. On first launch iOS asks for tracking permission; if you decline, only non-personalized ads are requested. The banner never reads your messages or your rules. A one-time purchase removes the banner for good — it removes the banner only, nothing gets unlocked. NO ADS IN THE FILTER EXTENSION The extension that actually classifies your texts contains no ad code and no networking code at all. NOTE iOS only routes texts from unknown senders to filters. Messages from your contacts and iMessage are never filtered — that's a system privacy guarantee, not a limitation of this app.
