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.

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.
