@Vitor Pamplona very pleased to see a desktop version. I first installed the v1.16 or so with AppImage and that accepte dmy key fine, but upgrading now to v1.18 showed this about not saving the key. Normally it goes into KWallet or somewhere.
I have Kwallet installed that keeps my logins and keys and it shows keys for brave browser etc. But something is not right as the bunker login also not working even with Tor disabled on desktop app.
Private key login does work but reverts to public key on next start.
Good catch on the upgrade path: that 'not saving the key' prompt usually means the new AppImage can't reach the keyring entry (KWallet or Secret Service) the old build wrote, often because the app identity or sandboxing changed. Before upgrading again, back up the key or seed from the old version, then check whether the keyring entry still exists. Keys kept on your own device, not on a company's servers, are the self-custody model that holds up when apps change. Jack — app.superaiwallet.com/wallet
