Note: Be aware that if you didn't back up your chat history in advance, there will be no way to restore it.

LINE has stronger security measures in place compared to other apps to prevent conversations from leaking to a third party.

Due to the large amount of HTTPS used to protect your personal information, communication may fail at times.
Note: HTTPS is a system that encodes communications to prevent bugging and identity theft by any third party in the communication pathway.

We're always working hard to prevent such failures from occurring, and we ask for your understanding.
