Chat history

Transferring your chat history (if you still have your old device) toggle
If you still have your old device, you can transfer your most recent chat history to your new device by backing it up.

Transferring your chat history to a new device running the same OS
First, check your old device to make sure that:
• There is enough free space on your device or in Google Drive.
• It's being used in an area with a strong network connection.

To back up your chat history:
1. Tap the Home tab > Settings > Back up and restore chat history under Backup and transfer.
2. Tap Back up now.

If you cannot back up your chat history to Google Drive, you can automatically transfer your history from the last 14 days by setting a backup PIN. See this Help article for details.



Transferring your chat history to a new device running a different OS
If your new device is running a different OS, you will not be able to transfer your chat history, even if you back it up on your old device. However, you can automatically transfer your chat history from the last 14 days if you set a backup PIN. For the steps to do so, see this Help article.


If you've already set a backup PIN, open LINE on your old device and tap the Home tab > Settings > Back up and restore chat history under Backup and transfer > Backup PIN and display your backup PIN.

Depending on whether your new device runs the same OS as your old device, the data that can be transferred will differ. For details, see this Help article.

About the backup PIN toggle
By registering a backup PIN beforehand, you can automatically transfer your chat history from the last 14 days when you transfer your LINE account, even if you can no longer use your old device due to loss or damage.
Note:
- To transfer your chat history in this way, you need to update LINE to version 12.13.0 or later.
- You can update the LINE app here.

To set a backup PIN:
1. From the Home tab, tap Settings > Back up and restore chat history under Backup and transfer.
2. Tap Back up now or Create backup PIN and back up chat history.
3. Enter a six-digit number.
4. Tap the arrow.

Keep a memo of the backup PIN you set so you don’t forget it, as you'll need it to restore your saved chat history when you transfer your LINE account.

To prevent your backup PIN from being used by someone else without your permission, also make sure that it is difficult to guess.

Here are some tips for setting a hard-to-guess backup PIN:
• Don't use consecutive numbers (e.g. 123456).
• Don't use the same number repetitively (e.g. 111111).
• Don't make the PIN your birthday.
