“[Instagram] shares a staggering 79% of your data with other companies,” explains pCloud, referring to Instagram checking 11 of the 14 labels. “Including everything from purchasing information, personal data, and browsing history. No wonder there’s so much promoted content on your feed. With over 1 billion monthly active users it’s worrying that Instagram is a hub for sharing such a high amount of its unknowing users’ data.”
