TOKYO -- Technicians at a Chinese company affiliated with the Japanese provider of the Line chat app had access to personal information of users in Japan.

Line Corp. made inadequate disclosures on foreign access to data in its privacy policy. The company has reported the incident to the Personal Information Protection Commission here and said it had already moved to end the Chinese affiliate's access. A third-party committee will soon be set up to investigate, according to a news release by Line on Wednesday.
