Demumu - Are You Dead? 死了么

Simple safety app for solo living with daily check ins and automatic alerts

demumu - Are You Dead? 死了么 sileme is a lightweight personal safety app designed especially for people who live alone. It provides invisible yet reliable protection through a simple daily check-in system and automatic emergency notifications, helping you stay connected to those who care about you without disrupting your routine.

How it works

Set up one trusted emergency contact - such as a family member or close friend-by entering their name and email. No account registration or login is required. Once set up, you simply tap the app to check in each day. The app quietly monitors your activity in the background. If you fail to check in for consecutive days, demumu automatically sends an email alert to your emergency contact the following day, signaling a potential safety concern and allowing them to take timely action.

Effortless and stress-free

demumu is built to be simple and unobtrusive. There are no complicated settings, no constant notifications, and no interruptions to your daily life. A single tap per day is all it takes to confirm you’re safe, making it easy to maintain even with a busy schedule.

Strong privacy protection

Your privacy comes first. demumu uses encryption to protect emergency contact details and check-in records. It does not request unnecessary permissions such as location access, and it does not collect irrelevant personal data. The app is designed to minimize data exposure while still delivering reliable safety support.

Designed for solo dwellers

Whether you are a professional living alone, a student away from home, or someone who simply prefers an independent lifestyle, demumu acts as a quiet safety net. Regular check-ins reassure your loved ones, while missed check-ins trigger early warnings that can make a real difference in emergencies.

Alone but not lonely-demumu stands by your side with simple, thoughtful protection. Make solo living safer with a tool that cares about your security, respects your privacy, and brings peace of mind to both you and the people who matter most.
