Call Sentinel

Stop Spam. Protect Your Privacy. Call Sentinel is a high-performance call screening utility designed to give you total control over your phone. Unlike other "spam blockers" that upload your contacts to a giant database, Call Sentinel processes every decision locally on your device. Your data never leaves your phone. Core Features: • Smart Filtering: Automatically rejects calls from numbers not in your contacts. • Wildcard Blocking: Block entire area codes or patterns (e.g., 1-800-*) with simple prefix matching. • Local Processing: No accounts, no cloud, no data harvesting. Your privacy is our priority. • Call History: View what number was blocked, with the ability to whitelist numbers instantly. Pro Features (One-Time Upgrade): • International Blocking: Reject all calls from outside your home country code with one toggle. • Prevent Voicemail: An experimental mechanism that answers and hangs up on rejected calls, preventing "ghost" voicemails from cluttering your inbox. Why Call Sentinel? In an age of constant robocalls and data leaks, Call Sentinel acts as a local firewall for your phone. By using the official Android Call Screening API, we provide a seamless experience that silences interruptions without ever seeing your private conversations. Important Note: Call Sentinel requires the "Call Screening" role to be enabled. This allows the app to see the incoming phone number and make an instant decision to allow or reject the call.
