Possibility of messages being viewed by third parties toggle
As messages sent in chats are covered by the law governing privacy of communications, no LINE employee or third party, besides the chat participants themselves, will be able to view them. LINE treats the chat history and other information of its users as important personal information, and handles them with the maximum level of security possible.
