The chat history that appears on LINE for Chrome is saved on our servers, while the smartphone version of LINE shows chat history that's saved on your device.
Because the chat history shown on your PC and smartphone is stored in different places, you may notice that:
• Even if you reinstall the LINE app and your chat history no longer appears on your smartphone, you can still check your chat history on LINE for Chrome for a certain period of time.
• Older chat history that's saved on your smartphone doesn't appear on LINE for Chrome.
• There are differences between the chat history on the smartphone version of LINE and LINE for Chrome.
Note: LINE for Chrome chat logs are deleted after the determined retention period has passed. (We do not disclose the retention period for security reasons.)
Let us know if we can make it better.
