As part of our ongoing commitment to enhancing privacy and security for our users, we are pleased to announce that from July, LINE is introducing “Letter Sealing (End-to-end Encryption)” as a default feature.

Since Letter Sealing encryption is available for all LINE users, those who have been using Hidden Chat can now enjoy the same peace of mind and sense of security from LINE’s main 1:1 chats without having to create separate Hidden Chat rooms. As such, from tomorrow, we will no longer support the Hidden Chat feature. 

Please make sure that you update to the latest iOS and Android version for the newest and best functionalities from

LINE will continue to take every measure possible to protect your privacy and strengthen the security of its app to ensure you have the best experience possible.

In case you have any questions or require technical assistance, please contact LINE Customer Support at
