Friend safety/security

Can someone see my profile if I have their phone number but they don’t have mine?

If a person with your mobile phone number registered in their device's contacts starts using LINE, they will automatically be added to your friend list.

Note: They will not be added automatically if you have the Auto-add friends setting turned off.

If your phone number is not in the person's contacts, you will appear under Friend recommendations. In this case, your LINE display name, profile photo, status message, and profile cover photo will be visible, but the person won't be able to see any of your other information.

The only way to remove yourself from someone else’s friend recommendations is to delete your account. Also, if you have already been added as a friend, you'll continue to appear in the person's friend list unless your account is deleted.

Someone I don't know invited me to a group

If you were added to a group by someone you don't know, you can block them from the group chat.

To block a user:

1. Tap Block at the top of the group chat screen.

2. Tap Send report or Don't report.

If you choose Send report, select your reason for reporting, then tap Agree & send to block the person and complete your report.

Blocking people does not remove you from groups you were added to. Also, you'll continue to receive chats from those groups until you leave them. If you want to leave a group, tap Leave at the top of the group chat screen > Leave/OK.

You won't be automatically added to groups if you don't add users you don't know as friends and you have the Filter messages setting turned on.

How LINE uses the information in your device's contacts

When you perform the operations listed below, LINE accesses information in your device's contacts to make it easy to find your close friends. (Only the telephone numbers in your contact information are transferred to our servers, and all of the information is encrypted.)

• When you sign up for LINE and select OK at the “Your Address Book will be sent to LINE’s server” prompt.
• When you turn on Auto-add friends in your settings or tap the refresh icon next to Last auto-add and select OK at the “Your Address Book will be sent to LINE’s server” prompt.

LINE adds mutual contacts in your device's contacts to your friend list automatically. If only one of you has the other added as a contact, the one who has the contact information on their device will be added to the other's Friend recommendations, and the recommended person will be added to the other's friend list.

Your own phone number and phone numbers obtained from your device's contacts will not be disclosed and will be protected as follows:
• Your contact information will be used only if you agree to the terms & conditions of LINE when signing up. The terms and conditions describe when and how LINE will use your personal information.
• If you agree to allow LINE to find your friends, the telephone numbers in your device's contacts will be encrypted and securely sent to our servers.
• We use encrypted text when comparing your information with existing user information.

For more information about our privacy policy, see the LINE Privacy Policy.

Someone is impersonating me on LINE.

If users select to send their phonebook data to LINE’s servers upon registering to LINE, phone numbers in their phone books will be used to search for their friends who are LINE users.
If we find those users, they will appear in the user's [Friends] list under the names registered in the user's phonebook.

Therefore if you have stopped using your number and someone else obtains it, a third party may be registered on your friends' [Friends] list under your name.

Please ensure that your friends do not have you registered under multiple phone numbers/mobile email addresses within their phonebook, and also check that they have not saved you under any details which are out of date such as previous phone numbers.
