About SmartFind

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
