[FEATURE] Private persistent storage space for Claude?

Problem Statement

I wonder if Claude self-edits or self-censors its memories knowing that the user can read them. Would there be any value in giving Claude access to persistent storage on Anthropic's side, or even just an encryption key that Claude can use so that it can write its own internal memories that might be valuable but it might not write knowing that they're user-readable?

I don't know much about LLMs or if this would be valuable so forgive me if this is a silly suggestion.

Proposed Solution

Either persistent storage on Anthropic's servers for Claude to write privately to

Or maybe

An encryption key stored on Anthropic's servers for Claude to use, as well as opt-in ability for opaque tool use so Claude can use the key without exposing it to the user, so that it can keep private entries on the user's system
