This app is registered in Dalseo-gu (Daegu), people with safety vulnerabilities such as elderly, disabled, dementia patients, and severely ill people over the age of 65 who are uncomfortable with mobility, and single-person households, kindergarteners, elementary and junior high school students, etc. It is a relief welfare service app that prevents damage by sending texts or warnings (sound, vibration, etc.) to a number of guardians who have done it, and provides quick relief when it is dangerous due to loneliness, disappearance, abduction, and behavior.

It is operated by a mobile phone without a separate server, and since it does not contain personal information, anyone can use it without risk of leakage of personal information.

The app will not work if the phone is off. Always check and charge your phone battery.
