SmartFind — Open Source Password Manager App

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
