I stopped using Dropbox years ago after they had the gall to delete some of my files and email a warning that pirated files weren't permitted. Except that they weren't pirated files - they were MP3s ripped from my own CDs for my own personal use. That's when I realized that they actually scan your files and there was no privacy, completely unacceptable. For some years I've used Sync.com, which is vastly better, but sadly their software and systems are completely broken once you get beyond a certain total size of file data (probably around 1TB, but they're happy to take your money for much more space, which can't be used because of their system bugs.)
