Privacy

  • Only storage + scripting + host_permissions — nothing more
  • Storage: saves colors, font size, blacklist locally
  • scripting: only injects the generated CSS into the current tab (isolated world); it does not read page content or run remote code
  • host_permissions: only for CSS injection. Does not read DOM text, images, form data or cookies
  • No browsing history, no tracking — external connections limited to optional license validation, optional Cloud Sync (Premium, via your browser account) and Google Fonts when a custom font is selected
