If you send your typing patterns for passwords, couldn't they be decrypted by using the other collected typing data? Or do they mean you just enter the TypingDNA password into TypingDNA? I'd be more interested in a tool that prevents any typing data from ever leaving my computer (maybe by opening all web forms in a text editor).
