AI-powered Caller ID and Spam Call Blocker. Identify unknown numbers, block scam, fraud, robocalls and telemarketers. Find out who is calling you with smart caller name lookup — even when the number isn't in your contacts.

🛡️ TOP FEATURES

• Caller ID — see the name and risk score of any incoming call, even from unknown numbers. CallGuard AI matches numbers against your contacts and a community-built spam reputation database in real time.

• Spam call blocker — automatically block known scam, robocall, telemarketing and fraud numbers. Decide whether they ring, go silent, or are sent straight to voicemail.

• Scam call protection — instant warnings for high-risk numbers, with a one-tap Hang Up button on the in-call overlay so you can end suspicious calls in a single tap.

• Smart dialer & call log — a clean dialpad and call history built right in. Tap any call to see the caller's risk score, return the call, or block the number.

• Reverse phone lookup — find out who called you. See caller name, location and risk reports from the global community.

• Live call transcription — turn on transcription during a call and see your conversation written on screen. Useful in noisy environments, language barriers, or when you need a record.

• Block rules — auto-block international calls, calls from unknown numbers, or callers matching your custom rules during quiet hours.

• Spam community shield — opt in to share anonymized spam reports so the community catches new scam numbers faster.

📩 MESSAGE GUARD (Optional)

• Spot scam links in your SMS without granting SMS permission. Message Guard scans incoming SMS notifications via Android's Notification Access — only from system SMS apps, never from WhatsApp, Telegram, or other messengers — and warns you when a message contains a phishing link.

• You enable Message Guard explicitly from Settings → Message Guard, and you can disable it any time. The full SMS body never leaves your device — only URLs found in suspicious messages are checked against a safe-browsing database via our secure cloud function.

🔒 PRIVACY-FIRST

• Your call data stays on your device unless you turn on optional cloud backup.
• We never sell your personal data or share it with advertisers.
• We do not request any SMS permissions in this version. If you choose to enable Message Guard, the app will ask for Notification Access so it can scan SMS notifications for scam links — this is optional and can be revoked any time from Android Settings.
