About this page

This page gathers every public program listed under lycorp.co.jp and the companies LY Corporation owns: platform programs, self-hosted policies and security.txt contacts. Each program's own policy decides what is in scope and what it pays; check it before you test. Ownership comes from settled, public acquisitions, or from a program's own text naming LY Corporation.
