Send files straight to the people you trust — encrypted end to end, split into shards, and delivered peer to peer. Nothing is stored on a server, and nothing is left behind.
Run ShardLock.exe — it installs the app, drops a desktop icon, and keeps itself up to date every time you open it. (If Windows warns, click “More info” → “Run anyway.”) The app needs a free account. Need one? Click here. · Portable ZIP
AES-256 with per-transfer keys. Your files are unreadable to anyone but the recipient.
Files move machine to machine. The server only helps your buddies find each other.
No files on any server, and every temporary shard is wiped the moment a transfer finishes.
