I like your landing page, but the four topics you speak about have no visuals to provide context. The picture at the bottom looks just like Google drive. I think you should stop describing and showing what everyone else does, and focus on what you do. Just show what features you made to improve the experience and reduce the hassle.

The only thing your landing page would need to be to get sign ups is to state and show how your are different. I don't need to switch to your service to do the three things you have listed. I still think there is great room for improvement in online storage, and hope you can build something that comes closer to that.
