さくら連絡網 is an app designed for students and parents to receive school announcements through push notifications. With this app, users can ensure that important messages from the school are never missed. The concept of さくら連絡網 is to prevent any miscommunication in times of need.

For existing customers who have already registered their contact information, such as email or LINE, with さくら連絡網, they can simply input the invitation code issued from their personal page to start using the app. New customers, on the other hand, will need to follow the registration procedure provided by their respective schools.

Upon installation, the app requires users to input their authentication code, ID, and passcode, which can be found in the registration procedure document. Make sure to input the correct authentication code, ID, and passcode during the initial launch of the app.
