Fewer unwanted connections. More control over your browsing. Stay Secure & Ad Block is a DNS filtering and privacy utility that helps reduce unwanted connections while you browse and use supported apps. It blocks DNS requests to known advertising, tracking, phishing, scam, and malicious domains included in your active protection lists and rules. DNS PROTECTION Filter requests to listed domains at the DNS level, before a connection is established through that lookup. AD BLOCKING Reduce connections to known advertising domains across supported apps and websites. TRACKER BLOCKING Help limit connections to known tracking and analytics domains. PHISHING & SCAM DOMAIN BLOCKING Block requests to domains identified in the active lists as phishing or scam sites. MALICIOUS DOMAIN BLOCKING Block requests to domains associated with known malicious activity when they match the filtering rules. YOUR RULES, YOUR CONTROL With Premium, add domains to a custom blocklist and allow trusted domains with an allowlist. Kids Mode restricts access to allowlisted domains and their subdomains. Set up your trusted sites before enabling it. SEE YOUR PROTECTION AT WORK Check protection status, blocking statistics, and recent blocked domains in one place. Enable protection, approve the configuration requested by iOS, and confirm that protection is active. Keep protection-list updates enabled to receive available rule updates. FREE & PREMIUM Start with an essential ad and tracker protection list, statistics, and limited recent activity. Premium adds expanded lists, custom rules, an allowlist, Kids Mode, and access to the retained activity history. DNS filtering works with supported network traffic. It cannot block every ad or harmful connection, including content served from the same domains as content you want to view. Coverage depends on the active lists, apps, and network settings. The app filters domains; it does not scan files or remove malware. Premium is an auto-renewing subscription. Review the price and billing period before purchasing. Manage or cancel your subscription in your App Store account settings.

SpamRadar blocks spam texts and phishing attacks before they reach you — all on your device, in private. Most spam filters send your messages to a cloud server to analyze them. SpamRadar never does. Every message is classified locally using an on-device AI model. No message content ever leaves your phone. HOW IT WORKS When an unknown sender texts you, iOS routes the message to SpamRadar's filter. It scores the message in milliseconds using machine learning, link analysis, and sender reputation — then routes it to your inbox, promotions, or junk. Your messages stay on your device the entire time. WHAT IT CATCHES • Phishing links (fake bank, IRS, USPS, delivery scams) • Prize and lottery texts • Urgent account suspension threats • Suspicious international senders • URL shorteners hiding malicious destinations • Government impersonation texts WHAT YOU SEE The dashboard tracks every threat caught. See how many messages were blocked, flagged as promotions, or passed through. No message content is ever stored — only counts and categories. PRIVACY BY DESIGN Apple's message filter sandbox physically prevents network access during filtering. SpamRadar is built entirely within that sandbox. There is no server, no account, and no way for message content to leave your device. SETUP TAKES 30 SECONDS 1. Open Settings → Apps → Messages 2. Toggle on Screen Unknown Senders 3. Tap Text Message Filter → select SpamRadar SpamRadar is free. No subscription, no paywall.
