The only data being used in this plugin is the amount of 'keyup' actions that have occured in order for the checking of content function to run, and the text the user types into the text field of the post creation section on Reddit, Tumblr, and Facebook so they can be passed into the toast notification. None of this data is actually stored anywhere nor is it being used for any other purpose. This plugin only has access to Reddit, Tumblr, and Facebook, it does not have any permission on any other sites, it only has access to what the plugin is intended for. That being those three sites.
