Information used by LINE
We'll keep doing everything we can to provide the most convenient and secure experience possible with LINE, and will continue making improvements based on user feedback.
We appreciate your understanding and cooperation.
URL access information is collected only from users who have agreed to provide LINE chat usage data.
When collecting URL access information, we take the following measures to protect users' privacy:
• Only the domain name and the hashed variable part of the URL (path and parameters) is collected.
• Collected data is not linked to a user identifier.
It is very difficult to obtain an original URL from its hash, so we calculate our access ranking by hashing the URLs of widely used public sites and comparing the resulting hashes with the URL hashes we collected. We then calculate the number of site visits only for the sites with matching hashes.
We do not try to convert hashed URLs to the original URLs in any way.
When your friends on LINE use external apps (e.g. apps offered by companies other than LINE), those apps ask LINE whether it can access your profile information. The External app access setting lets you allow or deny such access.
Note: Your profile information includes your LINE display name, profile photo, status message, and uniquely assigned internal identifier (a unique number that LINE gives each user).
If you enable this setting, external apps will be able to access your LINE profile information, which is used in the friend requests and display of names in rankings for those apps.
For your reference, LINE Games and other LINE services can access your profile information regardless of your External app access setting.
The following information will be acquired.
Information about chats between friends
This includes which friends were in the chat room, the date and time of sent/received messages, "Read" marks, data formats used, and information on the use of features (such as the use of the "unsend" feature and accessed URLs).
Please be assured that the content of your chat messages (including images and videos) and calls will NOT be used.
Chats with official accounts
This means communication in chat rooms, including chat content (text messages, images, and videos). However, the content of chats with accounts used for industries which are deemed by LINE as having a high possibility of containing sensitive information (personal information or other information of a private nature) will be exempt. This includes industries such as financial and political institutions, state institutions, and hospitals.
This includes the content, date, and time of posts, data formats used, stickers posted in comments, time viewed, and number of times viewed. However, LINE VOOM posts set to “Only me” will be excluded.
Use of the app, including LINE's in-app browser, save feature, and sharing
If the features for saving and sharing data are used, information including the data formats and when the data was viewed will be acquired.
Website browsing information
This includes information pertaining to URLs you have viewed and the source information of the URLs accessed via the LINE app.
We aim to use the above mentioned information to bring all of our users an even better experience when using LINE’s services. For more information, see here.
