死了么-还活着么？

• One-click check-in, done in seconds
Open the app and click the middle button to complete your daily check-in. No complicated operations, no need to remember passwords or fill in a lot of information.

• Automatic email reminders for consecutive days without check-in
Pre-set a trusted person (family member, partner, friend, etc.) as an emergency contact.

If you miss several days, the system will send a reminder email to the recipient the day after the set number of days has passed, asking them to check on your status.

• No account registration required, use directly
On your first use, simply fill in your name and contact email address, and select "Remind me after several days of consecutive missed check-ins."

Afterwards, simply open the app once a day to minimize disruption to your normal life.

• Respect for privacy, collecting only minimal information
Does not collect real-time location data, does not read your contacts, and does not access call and SMS records.

Only saves: anonymous device identifier, your set contact email address and threshold number of days, check-in time, and other necessary data for the reminder function.

• Encrypted Information Storage: Local configurations and check-in records are stored using system security mechanisms; server-side data is protected and access controlled according to its purpose to minimize the risk of data leakage.

• Applicable to Various Life Scenarios:

For renters working alone in a different city;
For young people studying or graduating and living alone in another city;
For middle-aged and elderly users choosing to live alone;
For anyone who needs someone to "occasionally check if they're okay."
No matter where you are, just remember to tap once a day to leave a "I'm okay" record for those who care about you.

【Usage Tips】

This application is only intended as a daily safety aid and cannot replace official emergency services such as calling the police or seeking first aid.

In case of emergency or health problems, please contact local emergency numbers or professional organizations first.

It is recommended to communicate with your emergency contact in advance: how you would like them to contact you or come to your home to check on you when they receive the email.
