ETA - Thanks, missed that page on the site.

I get that the intentions are good, but https would provide exactly the same trust guarantees, and ultimately it bothers me that they would try to mislead people into a false sense of security like this. If their application is encrypting data which is sent to their servers, then that means their severs have complete access to your data. (Whether they choose to make use of this power is up to them. They certainly have it, though.)
Encrypting the data prevents it from being leaked if their servers are hacked and their database stolen, which is good. But acting like they have no power to access your data is absurd.
Now that I think about it, I never did move my stuff from Dropbox to SpiderOak, did I... hmmm, maybe today.

If they really had no access, then their server cannot do any "analysis" beyond storing it, and the app could as well just store it locally, or with Amazon S3 or whatever storage system the website already uses.
Obviously not everything is encrypted, or otherwise they don't realize that there is no reason for them to provide a simple storage service, considering most websites already have some way to store data.
Or maybe they want to hold the data hostage.
