There should be a name for this sort of software design. It's not just encrypted/privacy-oriented or whatever. It's a software design with a clear contract on who owns the data: the user.
E.g. Google Drive, which claims to take privacy seriously and also encrypts your data. But the data is not encrypted with a secret unknown to the server. How should my family members differentiate between the encryption Google claims it has and client-side encryption? For them it's all the same.
Maybe we need some commonly understandable name that a regular user can look at and know that this software is data-agnostic.
