If only I know the other person's phone number, can the other person see my profile? toggle
If a person with your mobile phone number registered in their contacts starts LINE, they will automatically be added to your Friends list. If you do not wish to automatically add friends, please turn off Auto Add Friends.

If they haven’t got your number registered in their contacts, you will be shown under their Friends Recommendations, where your LINE Display Name, profile picture, and status message (What’s Up? messages) will be displayed. However, no other information will be shown to the other person.

If you want to be deleted from their Friend Recommendations list, you must delete your account.

Likewise, once your account has been added to their Friends list, you will remain there unless you delete your own account.

For information on deleting your account, please see here.

We hope this helps!

Why does LINE utilize the contact information on my smartphone? toggle
When users carry out the procedures listed below, LINE will access the information required in the users’ contacts list/address book to make it easy for users to find their close friends (Only the telephone numbers and mobile email addresses in your contact information will be transferred to our servers. All information will be encrypted.)

1. At the registration screen, when users select OK at the “Your Address Book will be sent to LINE’s server” dialogue.
2. When the Auto Add Friends function is switched ON in Settings or when users push the circular icon next to the Last Auto Add dialogue, and then select OK at the “Your Address Book will be sent to LINE’s server” dialogue.

LINE will add mutual contacts to your Friends list automatically. If only one of you has the other as a contact, the one who has the contact information will be added to the other's Friend Recommendations list, while the recommended person will be added to the other's Friends list.

Your own phone number, and other information obtained from your contacts list/address book (phone numbers and email addresses) will not be disclosed and will be protected as follows:

1. 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.
2. If you agree to allow LINE to find your friends, the telephone numbers and mobile email addresses in your contacts list/address book will be sent to our servers.
At this time, the required contact information will be encrypted and securely transferred to our server.
3. We use encrypted text when comparing your information with existing user information.

Someone is impersonating me on LINE. toggle
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.
