Private file storage for people you trust.
Fly is an end-to-end encrypted vault for sharing files inside a closed circle. No public sign-up, no indexing, no scanning. You're here because someone gave you a key.

Built to keep small circles private.
Most storage is built for scale. Fly is built for trust — a quiet place for a handful of people to keep files that aren't meant for the open web.
Encrypted end-to-end
Files are encrypted in your browser with a key only your circle holds. What reaches our servers is ciphertext — nothing else.
Access by invitation
There is no public sign-up form to probe. Membership passes hand to hand, and every device is bound to a member key.
Continuous sync
Clients keep a live encrypted channel open so changes appear the moment they happen. Large files stream up in the background.
Three steps, then it disappears into the background.
Redeem an invite
A member sends you a code. It binds your device to the circle and generates your local key.
Drop your files
Anything you add is encrypted on-device and streamed up over a private channel. No previews leave your machine.
Share within the circle
Members see the vault update in real time. Nobody outside it can list, index, or reach the contents.
A small, quiet project.
We built Fly for ourselves first — a way to keep working files among a few people without handing them to a platform that scans, indexes, and monetizes everything it touches. It stays deliberately small: no growth targets, no ads, no public directory. If you're reading this with a code in hand, welcome. If not, this probably isn't for you yet.
Access is granted by members.
Fly has no open registration. The most reliable way in is an invite from someone already inside. If you were pointed here, use your code above.
