About this app
Leevalon-Are you dead-Demumu-check-in App
Leevalon-Are you dead-Demumu-check-in App is a simple app for people who live alone.
If you don’t check in for a long time, the app notifies someone you trust.
No cameras.
No tracking.
No constant monitoring.
Just a quiet way to let others know:
“I’m still here.”
Why this app exists
People joke online:
“Did you disappear?”
But for many people living alone, this question is real.
Leevalon-Are you dead-Demumu-check-in App was inspired by that reality — and by the idea that silence can sometimes mean risk.
This app doesn’t watch you. It just waits for you.
How it works
• Check in with one tap
• Set an inactivity time limit
• Add an emergency contact email
• If you don’t check in, they get notified
That’s it. No pressure. No daily nagging.
What makes it different
✔ Designed specifically for people living alone
✔ You control the rules, timing, and contacts
✔ No location tracking
✔ No health or medical claims
✔ Minimal data, privacy first
Leevalon-Are you dead-Demumu-check-in App is not a social app. It’s a safety net you hope you’ll never need.

Who it’s for
• People living alone

• Elderly users who prefer simple tools
• Anyone who wants peace of mind without surveillance
Simple, quiet, human
No feeds. No algorithms. No noise.
Just a small signal to the outside world —
in case one day, you stop answering.
