Smart Call Blocker — take back your phone.
Spam calls, robocalls, scammers, persistent telemarketers. Smart Call Blocker silences every one of them while making sure the calls that matter still get through. Built by Triple Minds with one rule: everything stays on your device. No analytics, no ads, no cloud — just intelligent call filtering you control.
🛡️ POWERFUL BLOCKING ENGINE
• Block by prefix (+91, 1800), suffix (0000), or contained digits
• Block exact numbers, country codes, area codes, toll-free, premium ranges
• Block private/withheld and empty caller IDs
• Block unknown numbers (allow only contacts) — strict safe mode
• Regex patterns for power users
• Schedule rules by time of day and day of week
⚡ SMART REPEATED-CALL DETECTION
A telemarketer calling three times in five minutes? Auto-blocked for 30 minutes. Every threshold is customisable.
✅ WHITELIST ALWAYS WINS
Add family, work, or doctors to the whitelist — their calls always come through, regardless of any rule you set.
⏱️ SAFE MODE TIMER
Expecting an important call from an unknown number? One tap allows every call for 15, 30 or 60 minutes, then snaps back to full protection automatically.
🔒 PRIVACY-FIRST BY DESIGN
• 100% offline — no servers, no internet needed to function
• Zero tracking, zero ads, zero third-party analytics SDKs
• Privacy Mode masks numbers in the blocked log
• App lock with biometrics or device PIN
• Full Privacy Policy & Fair Use Policy included in-app
📊 INSIGHTS DASHBOARD
• Today, week, month, and all-time blocked counts
• 30-day trend chart
• Top blocked rules, countries and numbers
📱 NATIVE ANDROID INTEGRATIONS
• Quick Settings tile to toggle protection from the notification shade
• Home-screen widget showing today's blocked count
• Material You dynamic colours (Android 12+)
• Light, dark and system themes
💾 BACKUP & RESTORE — SURVIVES UNINSTALL
Pick any folder (Documents, Google Drive, an SD card). Every change auto-saves to a single JSON file in that folder within a second. Reinstall the app, pick the same folder, and restore everything — rules, whitelist, blacklist, blocked-call history, and every setting.
🚨 EMERGENCY-SAFE
Emergency numbers (911, 112, 100, etc.) are always allowed, regardless of your rules. Smart Call Blocker cannot be used to block emergency services.
WHO IT'S FOR
• Anyone tired of robocalls and spam
• Privacy-conscious users who don't want their data on someone else's server
• Power users who want regex and time-based blocking
• Families who want a simple "only contacts" protection
PERMISSIONS WE ASK FOR
• Phone — required to be Android's default call screening app and receive call events
• Contacts — to recognise calls from people in your address book
• Receive Boot Completed — to re-arm temporary blocks after a restart
We do NOT request the call log permission. We do NOT collect, share, sell or transmit any data. Everything stays on your device.
