Depends on your jurisdiction. In Germany, for example, a court has recognized that Facebook enters in a contractual relationship with you when you register on the platform. As such, Facebook agrees to store and let you access your information on the platform in exchange for the permission to use that data for its own purposes. The highest court in Germany (BGH) confirmed this in a court case that Facebook lost where parents were denied full access to the Facebook account of their deceased daughter (they were only allowed to view the memorialized profile but not log in and read the chat messages, for example). The court found that the parents rightfully inherited the contractual relationship with Facebook in its entirety and as such had to be given access to the data that Facebook agreed to store and make accessible to its user.
