If You May Have Been Scammed, How to Save Your LINE Messages
First, the priority is to keep the harm from growing. This article covers only a general way to save and organize chats you took part in. It does not address whether something amounts to fraud or whether you might get a refund.
Not legal advice. This page is general information. Whether a court admits or relies on a chat is for the court; convokeep does not promise admission or any outcome. Ask a qualified lawyer about your case.
What should I do first?
Stop sending money or personal information, and do not delete chats or transfer records. Saving the chat history before you block the other person can spare you trouble later.
How do I save it?
Send the chat history as text and keep it as the original. For the steps, see How to send LINE chat history. Keep the other person's profile screen, any URLs they sent and your transfer statements separately too.
Is it okay to open URLs or attachments?
Do not open suspicious links; keep them as they are, as a screen capture or as text.
Where can I ask for help?
The police consultation line (#9110) and the Consumer Hotline (188) are commonly recommended. We could not open the official pages in this check, so confirm the latest numbers on the official sites.
What about the hash value?
It only shows the file has not changed since the export. It does not show what the other party deleted or who the person is. See What a hash value tells you.
Will I get my money back?
We cannot promise any result.
