I want everything Mother knows/finds out, to be stored locally (i.e. on my pc, not in the cloud), to be kept secure, private and I want to access it at any time from anywhere.... can Mother do that? I don't think so.

Still pretty good but as long as there isn't a privacy promise that would satisfy the basic security principles (Confidentiality, Integrity, Availability) I don't see it as a successful device.
