They are probably either lying or incompetent.

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.

No, there's no reason to go looking for conspiracies. Nor do I think their intent was malicious. I think they genuinely believed that this was beneficial. We should support them if they change their presentation from "we can't access your data" to "we're not evil, so if you trust that, then use us." We should let their actions speak for themselves.

See "Graph Analysis" section on the linked page, they make it pretty clear that there is info that is sent unencrypted but those parts aren't useful for reverse engineering. The data and source code itself sounds like it is encrypted though.
