Whether a site complies depends on how it is built, so no plugin makes a site compliant on its own. Essential Grid runs on your site: no tracking, no analytics, no calls to ThemePunch from your visitors’ browsers.
A grid can load content from other services: videos from YouTube or Vimeo, images from feeds such as Instagram or Flickr, and Google fonts. Name the ones you use in your privacy policy. On the new front end of 4.0, a video loads nothing from its host until the visitor plays it, and YouTube videos can use YouTube’s privacy-enhanced mode.
