             | data un-practically-retrievable.
             | 
             | (And a third party because, similar to the browser+CA

             | guarantees of good behavior seems effective)
             |

             | or "no unencrypted user data at rest"
             | 
             | ^ Cloud hosting encryption keys would also solve the ugly
             | UX edge of strong encryption around "I lost my key...

             | > Miscarriage is the sudden loss of a pregnancy before the
             | 20th week. About 10% to 20% of known pregnancies end in
             | miscarriage. But the actual number is likely higher. This
             | is because many miscarriages happen early on, before people
             | realize they're pregnant.
