CallShield – Spam Call Blocker Live

CallShield — Block unwanted calls everywhere Tired of spam, scams, telemarketers and harassers? CallShield is a privacy-first call blocker for Android that filters unwanted calls before they ever disturb you — not only on your phone line, but also inside your messaging apps. Where ordinary call blockers stop at the SIM, CallShield goes further: it also blocks unwanted calls from WhatsApp, Telegram, Signal, Viber, Messenger and Instagram. Each app can be turned on or off independently. EVERYTHING STAYS ON YOUR DEVICE CallShield runs entirely offline. It has no internet access, creates no account, and never sends your data to any server. No cloud, no ads, no trackers, no data selling. Your contacts, call history and lists stay on your phone — always. KEY FEATURES • Native call screening — intercepts incoming calls via Android's CallScreeningService and silently blocks unwanted numbers before they even ring. • Whitelist & blacklist — allow only trusted numbers, or block specific nuisances. It's your choice. • Block unknown numbers — automatically silence callers who aren't in your contacts. • Multi-app blocking — extend protection to WhatsApp, Telegram, Signal, Viber, Messenger and Instagram. • Quiet hours — filter only during a chosen time range, such as at night. • Emergency mode — let everything through in one tap when you're expecting an important call. • Logs & dashboard — a clear history of blocked and allowed calls, with useful statistics. • Import / export — add numbers from your contacts, and back up or restore your lists. TWO SIMPLE MODES • Whitelist mode: only your contacts and trusted numbers can reach you; everything else is silently blocked. Perfect for total peace of mind, or for a child or an elderly relative. • Blacklist mode: all calls come through normally, except the numbers you've blocked. Perfect for silencing specific nuisances without missing anything else. PRIVACY & PERMISSIONS CallShield asks only for what it needs to filter your calls, and every permission is optional: • Phone state — to identify the incoming call for screening. • Contacts — to recognise trusted callers and add numbers to your lists. • Notification access — to detect incoming calls from the messaging apps you enable. • Accessibility service — used only to detect the call screen of messaging apps and automatically hang up an unwanted call. It does not read any other content, never records your screen, and transmits nothing. This feature is optional; phone-call blocking works without it. Take back control of who can reach you.
