This application allows you to pre-register one or multiple location areas.
While the app is running, it periodically retrieves the device's location using GPS,
determining whether the device is inside or outside the registered location area.
If the device moves outside or inside the registered location area, its location is notified via email.

Examples of Use:

・You can use this app on your child's smartphone to send message notifications to the parent's smartphone,
assisting in monitoring the child's safety.
・You can use this app on an elderly person's smartphone to send message notifications to a caregiver's smartphone,
assisting in monitoring the elderly person.

Various other uses are also possible.

This is NOT a Monitoring App
The user of the device can always choose to start or stop the monitoring (GPS information retrieval) at any time.
The app operates based on mutual trust between the user and the guardian or caregiver.

Please note that GPS accuracy is not consistent and cannot be guaranteed,
as it depends on the circumstances during use.
Please use the app with this understanding.

Function Overview:

・Location area information is defined by a combination of latitude (X), longitude (Y), and diameter (R),
representing a circular area with the center at latitude X, longitude Y, and a diameter R (in meters).

・When GPS information is retrieved, the app detects whether the acquired coordinates (latitude a, longitude b)
are inside or outside the circular location area.

Two Detection Modes:

・Outside Area Detection Mode:
When GPS coordinates are determined to be outside all registered location areas, an "outside area detection" is triggered.
Notifications are sent every 15 minutes, up to 16 times.
If, during this state, the coordinates are detected inside a registered area,
an "inside area return" notification is sent once, and the "outside area" state is cleared.

・Inside Area Detection Mode:
When GPS coordinates are detected inside a registered location area, an "inside area detection" is triggered.
Notifications are sent every 15 minutes, up to 16 times.
If, during this state, the coordinates are detected outside all registered areas,
an "outside area return" notification is sent once, and the "inside area" state is cleared.

Free Version Restrictions:

・Notifications will not be sent every 15 minutes.
Both "outside area" and "inside area" detections will trigger only a single notification per occurrence.
・The number of notifications is limited to a maximum of 30 per month.
Once 30 notifications are reached, no further notifications will be sent until the next month,
when the count is reset to allow up to 30 notifications again.
・Banner ads will be displayed.

These are the only restrictions for free users.
There are no other limitations.
