Creation Guidelines

  • The following changes have taken place starting with LINE 9.6.0:

    1. The menu buttons on Android have moved to the bottom of the screen.
    The menu buttons for creators' themes will also be moved to accommodate this change, but no new files are required from creators.

    2. The Friends tab has become the Home tab in select regions.
    In keeping with the Creation Guidelines for themes, please provide graphics for the new Home tab icon.
    To update themes already on sale, add the required images and resubmit your theme for review.

Unacceptable Themes

  • · Themes with poor visibility, such as icons that are visibly corrupted and difficult to see or that blend in with the background image.
  • · Themes that do not feature good overall design balance (E.g., no unifying theme among icons, icons featuring only text)
  • · Images that only contain text (no illustrations)
  • · Themes that are duplicates of themes that are already available or currently under review (including simple color-revisions of existing icons)
  • · Content that offends public order and morality, is suggestive of under-age drinking or smoking, contain sexual or violent imagery, or may fuel nationalism.

Other Notes

  • · Any paid themes should not be used for advertisement purposes. Theme graphics, titles, and text cannot act as advertisements (including announcing sales or release dates) or feature superfluous or unnecessary corporate logos.
  • · Requiring a user's personal information or ID in order to purchase a theme is strictly forbidden.
    Content that mentions any internet service, messenger app, or similar services, or consists of any characters related to such services may not be sold in the Creators Market.
  • · For more details, please see the theme review guidelines.
