What Demumu is
Demumu is a personal safety app for people who live alone. The mechanism is deliberately simple: you enter emergency contacts once, then open the app each day and tap a single button to confirm you are fine. If you miss consecutive check-ins, the app sends an email to those contacts so somebody notices that something is wrong. The site says it does not track your location, uses end to end encryption, keeps data on your device rather than a server, and needs no account at all. There are no ads and no data selling. It is a one time $0.99 purchase that includes future updates.
What you can do with it
- Check in with one tap each day
- Set emergency contacts who get an email if you go quiet
- Keep everything on device with no location tracking
- Use it without creating an account
Who it is for
- People living alone who want a quiet safety net
- Families worried about an elderly relative living alone
- Privacy focused users who do not want a tracking app
What to watch out for
It is iOS only, so there is no Android version, and you should confirm your device is supported before you rely on it. The alert path depends on your contacts actually reading an email, so choose people who will notice and respond, and tell them in advance what the message means. This is a safety net, not an emergency service: in a crisis you still need to call local emergency numbers, and a missed check-in is a prompt for someone to check on you, not a dispatch. Finally, the app is a one time purchase today, but pricing and features can change.
