Review Guidelines

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.
