Export & Import Notes
A note backup is the fast path back. It carries no spending key, so the file is safe to keep alongside your other backups.
You can move your notes between your own devices as a JSON note backup — without re-scanning the chain.
Export (Private Vault → Export JSON) produces a JSON file — or copies it to
your clipboard — holding every note as { commitment, encrypted memo }. It is a
closed backup: it carries only data that is already public on-chain and no
spending keys, so the file grants nothing on its own.
Import (Private Vault → Import Notes) takes that file or pasted text and decrypts each memo with your wallet's keys. A memo that opens is your note and is restored fully spendable; a memo that does not open belongs to someone else and is skipped. This proves ownership by decryption and needs no chain scan — so importing someone else's backup recovers nothing.
A backup is the fast path you prepare in advance; Rescan is the fallback that always works from the chain. Notes stay spendable after import even without a Merkle proof — the proof is fetched fresh from the chain at spend time.
