FileSecond: face-to-face file sharing without the awkward middleman

Field notes

FileSecond organizes nearby file exchange around a temporary channel rather than an account or inbox. The creator chooses a one-, six-, or 24-hour lifetime, displays a QR code or joining code, and can add a six-digit PIN. The homepage lists PC, Mac, iPhone, and Android as supported device types. It states that channels disappear when closed and that PIN protection strengthens encryption, though the extract provides no technical documentation for either claim.
