About LINE VOOM privacy settings toggle
With LINE VOOM (formerly Timeline), you select the people you want to follow from your LINE friend list. (You are asked to do this initially from the From friends to followers pop-up.) After you select who to follow, your LINE VOOM Following list and LINE friend list are managed separately.

The posts that you see on LINE VOOM are from the people you're following on LINE VOOM, not the users in your LINE friend list. In the same way, your posts will be visible to people who have followed you (your Followers).

After you initially set up your Following list, a list called "LINE friends" is created automatically under Privacy settings > Custom lists, but this list is managed separately from your actual LINE friend list. See this Help article for details.

For more information about how to configure LINE VOOM privacy settings and their specifications, see this Help article.

"This message can't be decrypted" appears and I can't see sent/received chat messages toggle
If you see any of the following messages after transferring your account on a smartphone, you may not be able to view past chat messages.

- "This message can't be decrypted"
- "This message wasn't backed up and restored from your previous device. Unfortunately, there's no way to read it on your current device."
- "Unable to display message as it couldn't be decrypted."

If any of these messages appear and you cannot view your past chat messages, there is unfortunately no way to re-display them. In this case, please ask the other person in the chat to send you any old messages that you need.

The messages above appear when:
• You transfer your account to a device with the same OS (e.g. iOS to iOS) without backing up and restoring your chat messages.
Note: To view old chat messages on a new device, you need to back them up in advance and restore them.
⋅You transfer your account to a device with a different OS (e.g. iOS to Android).
Note: If you transfer your account to a device with a different OS, you cannot transfer your past chat messages.
⋅You receive chat messages while transferring your account.
Note: Any chat messages you receive while transferring your account cannot be transferred to your new device.

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 > Chat history backup under Backup and transfer.
2. Tap Back up now or Create backup PIN and back up chat history.
3. Enter your backup PIN.
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.

Sharing posts to your friends on LINE toggle
With LINE Timeline (the service we offered before LINE VOOM), there was a Friends privacy setting that let you share posts to only your friends on LINE. However, this privacy setting can no longer be used after you select the friends you want to follow on LINE VOOM from the From friends to followers pop-up that initially appears.

Instead, you can share posts to just your friends on LINE by using the LINE friends custom list that is automatically created after you initially set up your Following list.

To share posts to your friends on LINE: 
1. Tap Voom > "+" at the bottom right of the screen > Write.
2. Tap Public, the custom list name, or Only me at the top of the post editing screen.
Note: The privacy setting you choose will remain the next time you make a post.
3. Select Custom lists > LINE friends.
4. Tap "X" at the top of the screen.

Keep in mind that the LINE friends custom list will not automatically update after it has been created. If you don't want to share a post with everyone in the LINE friends custom list, you can delete users from it by tapping "-" > Remove.

If you have a new LINE friend you want to share your posts with, follow them and add them directly to the LINE friends custom list. See this Help article for details.

Important: If you block a friend on LINE after initially choosing who to follow, the LINE friends custom list will not automatically update. To prevent your posts from being seen by user you blocked on LINE, you will need to also block them on LINE VOOM.
