Parent poster seems to be talking about this, which is a standard feature of any ToS that allows services to operate at all. I think this para clearly tells the user that he or she retains the rights to content, and it goes on to say that Grammarly only needs these rights to provide the service and improve the algorithms. I don't think it says that Grammarly get to keep the content and do what they like with it. > You retain all right, title, and interest in and to your User Content.
