The LINE Local Search score is based on multiple types of data collected from LINE's tens of millions of users, including search results clicked, search queries entered, URLs accessed, and users' current locations.
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.
