As messages sent in chats are covered by the law governing privacy of communications, no LINE employee or third party, besides the chat participants themselves, will be able to view them. LINE treats the chat history and other information of its users as important personal information, and handles them with the maximum level of security possible.
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 iPad or PC after turning on Letter Sealing, you'll be required to verify your identity the first time you send a message by entering a 6-digit verification code on the smartphone version of LINE.
As voice and video calls are made over an internet connection, you may not be able to hear the other party, or they may sound broken up in the following cases. Please ensure that you have a stable internet connection.
The following are the main causes for such issues.
- You are connected to a Wi-Fi network accessible by the general public (we recommend using a 3G or 4G network).
- You are updating apps, or uploading or downloading files.
- The signal is weak.
- Some router settings are affecting your connection.
Both parties should try the following.
1. Update the app to the latest version from the URL below.
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.
When using external devices via Bluetooth, the performance of the external device is dependent on the main device. We cannot guarantee that they will function properly.
It may sometimes take a while for the actual message to be received (displayed) after the notification is received. If you are still having problems, please try the following steps.
1. Go back to the list of chats, then open the chat you are having problems with again.
2. Restart your device.
3. Update your LINE app from the URL below. http://line.me/update
Depending on your Wi-Fi connection the badge may not appear or may appear delayed.
