Field notes
Both devices open the app; the receiver enables its microphone, while the sender selects a file or types a message. The browser encrypts files with AES-128-GCM, uploads the encrypted copy, and uses a brief speaker chirp to deliver the key; the page says the relay deletes its copy. Free transfers are capped at 15 MB, with a listed 1 GB Pro tier. Tondavo says the app remains on chirpfile.com during the name change.
