It is privacy maximised, built on Nostr and encrypted so only the parties involved can find and, if found, read.
In incognito mode (a bearer ebill) only the payer's business name is known, every other party (payee and subsequent endorsees) can be anon if desired, needs just an npub to control the ebill.
