Alive: Silent Safety Check-in Tool for People Living Alone

Summary

Alive is a minimalist safety tool for solo dwellers that uses silent daily check-ins. Users set a timer and tap once per day; if they miss check-ins, the system automatically sends tiered email alerts to emergency contacts. The service requires no sign-up, collects no location data, uses minimal permissions, and encrypts all contact information and logs. It's designed to be invisible during normal use but activates alerts when needed.
