LINE Marks LINE Privacy Day on Jan. 28 with Special Website Introducing the Features, Systems, and People Protecting User Privacy

2022.01.28 Corporate

TOKYO – January 28, 2022 – Coinciding with international Data Privacy Day*1 today, LINE Corporation ("LINE") has opened a special "LINE Privacy Day 2022" website to mark LINE Privacy Day and share the measures it is taking to protect user privacy.

*1 Data Privacy Day: An offshoot of Europe's Data Protection Day that originated in the U.S. and Canada in 2008. Focusing on respect for privacy and building trust toward data protection, it aims to generate awareness and dialogue on data confidentiality and protection.

The website provides information on the measures—features, systems, and people—that LINE has implemented for the LINE app and within the company to protect privacy and give users peace of mind.


1.      Features that protect
LINE has developed and implemented an end-to-end encryption technology called Letter Sealing to ensure that the content of chats and calls can only be seen by the people participating in them. Letter Sealing is currently applied to text messages and location pins*2 sent over the LINE app (limited to messages in chats with 50 or fewer participants) and one-on-one voice and video calls. *3


2.      Systems that protect
Since LINE provides a variety of services that handle users' personal data, it has implemented the Privacy Impact Assessment process for determining risks and impacts on privacy so that it can offer secure experiences to users.


3.      People that protect
To ensure that the handling of user information complies with laws and regulations and is sufficiently secure, LINE has established the Data Protection Officer (DPO) position for overseeing privacy impact assessments and also supervising the handling of user information for each service, independent from the planning and development teams.

*2 "Location pins" refers to the location information that LINE users can send to each other in chats.
*3 This encryption will only apply if all participants in a chat room have the Letter Sealing setting enabled. Letter Sealing is not supported for chats or groups of 51 people or more.

More in-depth information is available on the website.
