Description
Block spam calls and robocalls before your phone rings — with zero cloud uploads and zero access to your contacts. Built specifically to protect seniors and families from phone scams.
Callro uses the Gauntlet Engine, a 26-layer on-device screening pipeline that analyzes every incoming call in under 40 milliseconds. All processing happens on your phone. No data ever leaves your device. Ever.
━━━ WHAT MAKES CALLRO DIFFERENT ━━━ - Zero contacts access — we never read your address book - Zero cloud uploads — your call data stays on your phone, always - No audio recording — we use call metadata only - No ads — ever. We charge $9.99/month so your data stays yours - One permission only: Android Call Screening
━━━ HOW IT WORKS ━━━ 1. A spam call or robocall arrives 2. Callro intercepts it before your phone rings 3. The Gauntlet Engine runs 26 screening checks in under 40ms 4. Spam is silenced or blocked. Legitimate calls ring through.
━━━ WHO IT'S BUILT FOR ━━━ - Seniors tired of Medicare scam calls, IRS scam calls, and Social Security threats - Adult children protecting elderly parents from phone scammers - Anyone receiving robocalls, warranty scam calls, or neighbor-spoofed numbers - Privacy-conscious users who refuse to hand their contacts to an app
━━━ UNLIKE TRUECALLER, HIYA, AND ROBOKILLER ━━━ Most call blockers upload your contacts to their servers to identify callers. Truecaller requires your address book. Hiya stores call data in the cloud. Robokiller routes your calls through external servers.
Callro does none of this. We use only government-sourced spam databases from the FTC, FCC, and NANPA — no contact harvesting, no cloud processing, no data selling.
━━━ KEY FEATURES ━━━ - 26-layer Gauntlet Engine call screening - SIT Tone Defense — plays disconnect tone to automated robocallers - Neighbor Spoof Detection — catches calls faking your area code - FTC, FCC, NANPA government database integration - Shield Log — local call history, never uploaded to servers - Fortress Mode — temporarily let all calls ring through - One-tap whitelist for numbers you always want to receive - Works automatically — no settings, no maintenance
━━━ PRICING ━━━ $9.99/month. 7-day free trial. No credit card required. Cancel anytime via Google Play. No hidden fees.
━━━ PRIVACY ━━━ Callro is built on a privacy-first architecture. We are the only Android call blocker that requires zero contacts permission and zero cloud processing. View our full privacy policy at getcallro.com/privacy-policy
