형사사법포털 is a service that allows users to access criminal justice-related information without having to visit a law enforcement agency. With this app, users can conveniently retrieve information about ongoing cases from the police, prosecution, detention center, and court. The app also provides a feature to register and track cases of interest.

In addition to case information, 형사사법포털 offers a fine payment inquiry service, allowing users to check unpaid fines and payment history. Users can also access notifications from the prosecution office and learn about the support system for crime victims, including information about supporting organizations.

The app further enables users to submit complaints to the prosecution office and provides a "My Page" section where users can check the results of their complaint submissions and view their registered cases.

To ensure secure access, 형사사법포털 offers multiple login methods, including simplified authentication login after real-name verification and login using a public authentication certificate. However, certain services, such as case reservation and viewing electronic simplified orders, are only available on the PC platform.

Please note that using rooted smartphones or connecting USB devices to smartphones may restrict access to the service to protect personal information and prevent security incidents.
