<h4>RationalWP Plugin Directory</h4>
This plugin fetches a list of available RationalWP plugins from <a href="https://rationalwp.com/" rel="nofollow ugc">rationalwp.com</a> to display in the WordPress admin menu. Only the menu file version number is sent as a cache-busting query parameter. No user data is transmitted. The response is cached locally for 24 hours.

Data is only sent when a user explicitly clicks an AI suggestion button. The data sent includes the post title and up to 2000 characters of post content (stripped of HTML), along with the user’s own API key for authentication. No data is sent automatically or in the background.
