Saved symmetric results stored locally in this browser

Saved from the Symmetric tab with “Save to vault”. Show sends an entry back to the Symmetric tab ready to decrypt; Update asks for its key, decrypts it and sets everything up so you can edit the text and overwrite the entry.

Profiles separate sets of keys & vault, stored locally

Active profile

New profile

Master password optional — encrypts the active profile's private keys at rest

Master password

Export / import profile your keys + vault as a file
