The company behind Line, Japan's most popular messaging app, says Chinese engineers can no longer access the data of users in Japan.
It emerged last week that engineers at a Chinese firm that worked on Line's system could access users' personal information.
Line CEO Idezawa Takeshi apologized at the first meeting of a committee set up by new parent company Z Holdings to investigate the issue. He said Line no longer outsources any work to the Chinese firm.
He also said data of Japanese users stored in a center in South Korea will be moved to Japan.
Line has about 86 million users in Japan.
