Assuming this tool was intended for those who want to share photos on social media, Facebook and Instagram already strip metadata out from the photos you share otherwise anybody could scrape the photo and get metadata. I'm not sure for Twitter tho but I think it is the same.

Twitter also strips exif data from displayed images. That said, I would assume that all social media platforms permanently store that data (even though it's not in the displayed image), and would be forced to give it up under subpoena.

"all social media platforms permanently store that data" exactly but storing metadata has 2 purposes; one for security reasons and second for analyzing the data and creating advertising solutions based on that data.
