We respect your privacy above all else, and your sent/received messages and other information are treated with the highest level of security. LINE has established strict internal rules to ensure that your messages are protected.
Nothing you send or receive can be viewed by LINE or any third parties not participating in a chat.
With LINE, chat rooms are automatically created for recently added friends. "Start chatting with your new friend now!" is always the first message in these chats.
Also, if you or your friend turn the "Allow others to add me" setting ON, your chat room may be recreated and appear at the top of your chat list.
If a chat with a friend you haven't messaged recently appears at the top of your chats, it may be because that friend turned their "Allow others to add me" setting ON.
Rest assured that this message does not mean an account is being impersonated or has been stolen.
The GIF feature lets you use your own photos to create simple animations, which can then be sent in chats.
To make a GIF and send it in a chat:
1. Tap the photo icon next to the text box, then tap the photo list icon at the bottom right of the screen.
2. Select the photos you want to use and tap the GIF icon.

If you want to restore your chat history after changing devices, you need to back it up in advance.
To automatically back up your chats to Google Drive, follow the steps below.
Note: For information on manually backing up your chats, see this Help article.
1. From the Home/Friends or More tab, tap Settings > Chats.
2. Tap Back up and restore chat history.
3. Turn Enable auto-backup ON.
4. Select how often you want to back up your chats.
Your chats will be backed up automatically when you stop using your device and its screen has turned off.
Note:
- Your device needs to be connected to the internet and plugged into an outlet when the auto-backup refresh starts.
- If you can't use a Wi-Fi connection, you can still back up your chats with Use mobile data selected.
If an auto-backup fails, you'll receive a chat notification from the LINE official account. For more information about this notification, see this Help article.
If you want to restore your chat history after changing devices, you need to back it up in advance.
Before backing up your chats, be sure to:
• Turn Google Drive ON.
• Update LINE to the latest version.
Note: Photos and stickers sent in chats cannot be backed up or restored. If there are photos you'd like to save, consider saving them to Albums or Keep.
There are two methods available for backing up your chats to Google Drive.
Manually back up chats to Google Drive
Use this option to manually back up your chat history whenever you need to. For more information, see this Help article.
Automatically back up chats to Google Drive
Choose how often you want your chats to be automatically backed up. For more information, see this Help article.
You won't be able to back up your chats if you don't have enough free space on your device or Google drive. Be sure to regularly check how much free space you have and whether your chats were successfully backed up or not. For information about clearing space on Google Drive, see this Google Drive Help page.
If an auto-backup fails because you don't have enough free space on Google Drive or your device, one of the following error messages will appear in a notification from the app or on the settings screen.
Note: You will not receive a notification if an auto-backup fails for another reason.
• "Backup failed at XXXX on XXXX. Not enough free space on Google Drive."
• "Backup failed at XXXX on XXXX. Not enough free space on your device."
If you receive a notification like the ones above, or if you find that you cannot do a periodic backup in the LINE app, make sure that you have enough free space on Google Drive and your device, then try again.
If you're having issues restoring your chat history, it may be due to one of the following reasons.
• The Import chat history option does not appear
From LINE version 9.1.0, there is no longer a feature to back up and import your chat history from inside a chat. If Import chat history does not appear, you won't be able to import chat history saved on an SD card or LINE Keep.
• You didn't download the backup file from Keep
If you saved the backup file to Keep on LINE, you'll need to download it from Keep and save it to your new device after transferring your account.
• The backup file wasn't saved in the right location
Files created by selecting Back up all data are saved on either an SD card or your device.
If you're unable to import (restore) your chats, you'll need to manually move the relevant file to the folder titled "LINE_backup" on the device you want to restore your chat history on.
Please use a file managing app or connect your device directly to your PC to access the backup files and move them.
Note:
- If this folder doesn't exist, please create one.
- You will not be able to restore your chats if you did not select Back up all data from the Back up chat history option.
If you're not sure how to create folders or move files, please contact your device manufacturer.
• Your device doesn't have sufficient memory or your system specs are too low
The app may freeze or crash if your device doesn't have enough memory or the specs are too low. Please delete any unnecessary data and restart your device before trying again.
You can back up and restore your chat history with Google Drive by following the steps below.

With multi-person chats, you can start chatting with multiple friends right after being invited.
Compared to groups, the features you can use are limited, but multi-person chats offer the advantage of letting you easily create chats with multiple friends.
To start a multi-person chat:
1. On the Chats tab, tap the speech bubble icon at the top right of the screen.
2. Tap Chat.
3. Choose the friends you want to chat with, then tap Create.
Multi-person chats are group-like chat rooms created by inviting friends to a 1-on-1 chat.
With normal groups, a user that was invited cannot participate in the group unless they select Join. However, with multi-person chat rooms, you can immediately start chatting with friends who were invited.
Multi-person chats easily allow you to communicate with a number of friends; however, features found in 1-on-1 and group chats (such as Notes and Albums) cannot be used.
If you'd like to share things like information and photos with friends in a multi-person chat room, we suggest making a group out of that multi-person chat.
1. Tap the menu icon at the top of the chat screen > Other settings.
2. Tap Create group.
3. Select the friends you want to add and tap Next.
4. Enter a name, set a profile photo, and then tap Create.

You can unsend a message within 24 hours of sending it. This removes the message so that it can no longer be seen by anyone in the chat where it was sent, even after it has been read. To unsend a message, just tap and hold it, then select Unsend.
Important:
- Even if you unsend a message, everyone in the chat will still be able to see a notification saying that you unsent it.
- Anything (e.g. text messages, photos) deleted in a chat room cannot be unsent.
- We will not be able to recover or unsend anything deleted from a chat room.
You can unsend text messages, stickers, photos, videos, voice messages, songs shared from LINE MUSIC, URLs, contact information, location information, and files.

Letter Sealing is a feature that provides end-to-end encryption (E2EE) for chat messages. E2EE is a communication system designed so that messages saved on our servers are encrypted and cannot be read by anyone except the sender and receiver of the message.
Once the sender and receiver have both turned on Letter Sealing, they will be able to start sending messages with added security.
The following information will be encrypted:
• Text messages (not including messages sent through other services like YouTube)
• Location information
• 1-on-1 voice/video calls
Note: We plan to expand Letter Sealing’s functionality in the future.
If you use LINE for PC after turning on Letter Sealing, you'll be required to verify your identity the first time you send a message.
For information about verifying your identity to use Letter Sealing on LINE for PC, see this Help article.
Letter Sealing will be turned ON for the initial setup.
If you are using the iOS version of LINE and Letter Sealing is turned ON, you will not be able to preview messages.
We recommend keeping Letter Sealing turned ON at all times in order to protect your messages. If however, you would like to change the settings, please refer to the following steps.
Please be sure to follow the steps on the smartphone version of LINE. If you are accessing this Help article from your smartphone, tap here to move to the settings screen.

You may get notification messages from the official accounts of companies. These are messages for telling you things like package delivery dates and when monthly bills are due.
The name of an official company account has a gray, blue, or green icon next to it. To make sure that a notification message is from an official account, check to make sure it has an icon with one of these colors.
Notification messages let you receive helpful information without having to add the official accounts of individual companies.
Note: This feature is turned on when you tap Agree on the "Regarding Usage of Your Information" screen. You can turn it off separately in your settings.
Only notification messages that we have determined to be valid and appropriate are sent out to users, and messages will not be sent for the purpose of advertising.
How notification messages work
First, a company sends a message transmission request to LINE's servers based on a customer's phone number. A notification message is then sent to the account of the LINE user with that phone number registered.
The phone number sent from the company is hashed, and the information that LINE Corporation receives is only used for the purpose of verifying the message recipient, after which it is promptly deleted.
There may be times when we need to verify your identity via text message before we can send a notification or in order to confirm notification content which includes your personal information.
Requirements for sending notification messages
Notification messages are sent when they meet the three requirements below:
• The phone number sent from the company matches one registered to an existing LINE account.
• The LINE account has the Receive notification messages setting turned ON.
• The LINE account has not blocked the official account of the company sending the notification message.

Calling or chatting with users on different mobile service carriers is also free. LINE will not charge you, even if you are calling a friend in a different country or using the service while you are traveling.
However, like all other apps, you will be charged by your mobile service carrier for the data that you use. Depending on your price plan, you may be charged each time you connect to LINE, so we recommend using a flat-rate data plan.
Note: With a flat-rate data plan, you will generally not be charged additional data fees when using a 3G, LTE, or Wi-Fi connection. For more details, check with your mobile service provider.
Bluetooth devices can be used with LINE. Please understand, however, that we cannot guarantee such devices will work properly, as they rely on the performance of your smartphone.
