Callro: Spam Call Blocker

Block spam calls and robocalls before your phone rings — without giving up 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 real time. The blocking decision happens entirely on your phone. Contacts, call logs, and audio never leave the device.

━━━ WHAT MAKES CALLRO DIFFERENT ━━━
- Zero contacts access — we never read your address book
- The blocking decision is made entirely on-device — no network round-trip before a call is allowed or rejected
- 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 real time
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. Contacts, call logs, and audio never leave your device. We use government-sourced spam databases from the FTC, FCC, and NANPA to keep the Gauntlet Engine current — no contact harvesting, no data selling.
