This plugin relies on the transmission of data to a third party service (Refinitiv), including post content stored in WordPress as well as the API token you’ve generated as part of the service registration. Specifically, this data is transmitted when a WordPress user with appropriate capabilities (default manage_categories) clicks on the “Suggested tags from Open Calais™” link in the post tags meta box. The post content that is sent is determined by the state of the post content on last post update.
