SpaceBox Lite is one download that plays two parts. A SpaceBox receives and stores; a Sender encrypts and sends. Together they form one end-to-end loop where only the SpaceBox can read what arrives.
Turn your device into a SpaceBox. You get a host account, a QR invite, and an encrypted inbox that only your keys can open: a personal vault across your devices, or an organisation's drop box.
No account, no personal data. Scan a SpaceBox's QR invite and send files that are encrypted on your device before they ever leave it. You are identified only by a key, with nothing to subpoena.
Install SpaceBox Lite, open it, and choose your role. The same build runs as a SpaceBox or as a Sender.
Open the app on any device and pick SpaceBox or Sender.
A SpaceBox shows a code; a sender scans it. Tokens refresh automatically.
The SpaceBox approves each sender before anything can arrive.
Files are sealed on send and opened only on the SpaceBox's device.
Ciphertext only, held on our servers
From 1 approved sender
AES-256-GCM, sealed on the sender's device
ML-KEM-768 key exchange
