Suspicious calls are easier to handle when you're not handling them alone.
Phone scams are becoming sophisticated and conversational. FamilyShield provides calm context and family connection so no one has to navigate unusual calls in the dark.
Caller ID Impersonation
Scammers frequently spoof phone numbers to appear as trusted institutions, government agencies, or even local area codes.
High-Pressure Urgency
Unsolicited calls often rely on manufactured emergencies, demanding immediate action before you have time to double-check.
Family Isolation
When an unexpected call comes in, targets are forced to make rapid decisions in isolation without their family’s counsel.
Difficulty Verifying Trust
It is increasingly hard to tell whether an unfamiliar caller is genuine, leading to hesitation or inadvertent risk.
How FamilyShield Protects Every Call
Designed for intuitive protection without complex steps or technical setup.
A Call Comes In
FamilyShield monitors incoming phone calls using platform-native screening services (CallScreeningService on Android, CallDirectory on iOS).
Risk Context Evaluated
The number is checked against local address books, cached community blocklists, and risk indicators for robocalls or impersonation.
Actionable Context Shown
The user receives a clear visual indicator (Safe, Warning, or High Risk) with recommended options to reject, screen, or proceed with confidence.
Family Stays Informed
If an unknown or high-risk call is answered, an instant alert is sent to linked family guardians alongside quick access to trusted contacts.
Know when a call deserves a second look.
FamilyShield evaluates incoming calls against known scam patterns, community reports, and caller behavior metrics to provide instant context before you answer.
Platform-Native Integration
Uses Android CallScreeningService for real-time interception and iOS CallDirectory for directory blocking.
Possible Risk Indicators
Flags potential impersonation, high-frequency robocalls, and spoofing indicators without making exaggerated claims.
Stay informed when a loved one answers an unknown call.
FamilyShield links family devices securely. When a protected member answers an unknown or high-risk number, linked guardians receive a calm notification with basic context.

Keep the people you trust one tap away.
When an unexpected call creates doubt or urgency, hesitation can be dangerous. FamilyShield lets you configure up to two trusted contacts for immediate speed dialing.
Your safety should not come at the cost of your privacy.
We believe family protection requires total transparency. Here is exactly how FamilyShield processes your data.
No Call Audio Uploads
FamilyShield does NOT record, eavesdrop on, or upload audio from your phone calls. Call evaluation relies strictly on caller number metadata and risk indicators.
Encrypted Safe-Words
Emergency safe-words are stored strictly on-device in hardware-backed encrypted storage (Keychain/KeyStore). Safe-words are NEVER sent to cloud databases.
Hashed Contact Tokens
Address book matching uses SHA-256 hashed tokens (phone_hash). Raw contacts are never uploaded or harvested.
Local Processing vs Cloud Synchronization
We clearly distinguish what stays private on your phone versus what is processed in the cloud to keep family members connected.
Processed On-Device
Never leaves your hardware
- Emergency Safe-Word: Encrypted on disk using KeyStore/Keychain SQLCipher.
- Address Book Matching: Contact lookup is evaluated locally against your contacts.
- Cached Blocklist: Blocked numbers cached locally for offline call screening.
- Trusted Speed Dialing: Trusted contacts dialable even without cellular data.
Cloud Backend (Supabase)
Secured with Row Level Security (RLS)
- Family Links: Pairing graph between Protected Persons and Guardians.
- Push Tokens (FCM): Device tokens to route real-time family push notifications.
- Community Blocklist: Anonymized threat aggregation to protect all users.

Essential Call Safety Principles for Every Family
Technology is one part of family protection. Building calm habits is equally important.
Never Share Passwords or Credentials
Legitimate banks and government agencies will never ask for your account passwords, PINs, or one-time verification codes over the phone.
Verify Identity Independently
If a caller claims to represent an organization, hang up and call back using the official phone number listed on your monthly statement or official website.
Resist Manufactured Urgency
Scammers rely on creating panic or claiming immediate legal action. Take a deep breath and pause before taking any financial action.
Contact a Trusted Person
Use FamilyShield’s 1-tap trusted contacts to dial a family member whenever an unusual call leaves you feeling uncertain.
