Asymmetric encryption can't be reversed by the sender, assuming you use the recipients public key. When I was dealing with PCI and other frameworks, PGP encrypted data was given additional leeway for the sender in terms of how it could be stored or transmitted because in the context of the sender, the cipher text is gibberish.

I don't follow... since the use case here is personal storage, then the sender and the receiver are the same person
