For macOS and Windows
Send any file or folder straight from your computer to your contact’s computer, safely and securely. Right-click the file you want to send, then pick their email. They say yes. It goes directly, with nothing stored on the cloud in between!
Files go computer to computer. Nothing is uploaded and left on a server.
Each file is verified with SHA-256 before it is saved. Identical, or not at all.
Recipients see what’s coming and accept or decline before anything is sent.
How it works
Select a file, several files or a whole folder in Finder or Explorer and choose Send with Right Click Send.
Pick from your contacts or add someone by email. They’re asked first, even if they’re offline right now.
Once they accept, the files go straight to their computer and are checked before they’re saved.
Features
Works from Finder and Explorer, on files and folders. No app to open first.
Send by email. Anyone you send to is saved to your contacts automatically.
The recipient sees the file list and total size, then accepts or declines. A request to someone offline waits for them.
Hashed up front, checked in every chunk, and re-checked as a whole file before it’s moved into place.
Stop halfway and pick up later without starting over. Skip a single file, or stop and keep what’s arrived.
Mark a send High, Default or Low. It takes a set share of your measured speed, and respects the receiver’s connection too.
Security
A transfer only happens when both people agree, and it only arrives if it is exactly right.
Nothing is sent until the recipient accepts. If they decline, nothing moves.
Files go computer to computer. There is no server copy to leak, expire or forget about.
Hashed with SHA-256 up front, checked in every chunk, and checked again as a whole file. Anything that doesn’t match is never saved.
Your app accepts only transfers you agreed to. Someone who finds your connection still can’t deliver files.
Incoming paths are validated, so a sender can’t write outside your receiving folder, and nothing already there is overwritten.
Kept only as a keyed hash and encrypted ciphertext, never as plain text.
Download
One installer sets up the app, the background service and the right-click menu entry. Nothing to configure by hand, and it removes cleanly.
Sign up
Your email is your identity. We send a one-time sign-in link, so there is no password to remember. You’ll need an account to send, and so will the people you send to.
Questions
Transfers connect directly, so both computers need to be able to reach each other: on the same network, over a VPN, or through a forwarded port. Automatic connection through home routers is in development.
No. Our server only helps two computers agree how to connect. File contents go from one computer to the other.
Your request waits and shows as Pending acceptance. When they open the app, they see it and can accept or decline.
Yes. Drop several items or a whole folder and they go as one package, or send separately if you prefer. Interrupted transfers resume where they stopped.
