Description

SmartFind is a find-my-phone app triggered by SMS from designated contacts.

When a trusted contact sends an SMS containing your chosen keyword, SmartFind sounds a loud alarm — even if your phone is on silent or Do Not Disturb mode.

Features:
• Designated contacts — only people you trust can trigger the alarm
• Custom trigger keyword — choose your own secret word (default: FIND)
• Bypasses silent mode and Do Not Disturb — the alarm always sounds
• Biometric authentication — all settings changes require fingerprint or PIN
• Encrypted storage — contacts and settings secured with Android Keystore
• Cooldown protection — prevents alarm spam with configurable cooldown
• SMS spoof detection — validates SMS origin to prevent abuse
• Audit log — full history of alarm triggers and events
• Device admin — optional uninstall protection
• Battery-aware — adapts behavior based on power save mode

Privacy:
• Zero internet connections — operates entirely offline
• No analytics, no tracking, no cloud services
• All data stored locally on your device
• Phone numbers redacted in audit logs
