No storage
The server writes nothing to disk. Rooms are a Map in RAM that expires after 30 minutes.
Browser to browser · the key is yours
Send a file. Leave nothing behind.
Your browser encrypts the file and the recipient's browser decrypts it. The server only forwards sealed envelopes — it never sees the file, the key, or a record of them.
How it works
-
01
Pick a file
Your browser strips hidden details like photo location and seals the file with AES-256-GCM. Nothing is uploaded.
-
02
Send the link
A one-time link is created. The key sits after the # in that link, and the browser never sends that part to the server.
-
03
They open it
The file is decrypted in their browser. The server keeps no copy — when both tabs close, nothing is left anywhere.
01

Ready
Batch
JPEG, PNG, PDF, DOCX/XLSX/PPTX, MP4/MOV, MP3 and SVG metadata is stripped byte by byte, in your browser. Everything else is encrypted as-is.
No size limit · the file is never uploaded
Send the password through a different channel than the link — a call, a message, or in person.
If you lose the password the file cannot be opened. There is no recovery.

The key sits after the #. It is erased from the address bar the moment your recipient opens it.

This was a one-time link. It is now closed and the key is gone.

Stealth IP relay
On by default: the transfer takes our server’s path instead of a direct connection. Neither side sees the other’s address — not in the page, not in the network tab. The relay only ever forwards sealed bytes it cannot read. Switch it off for a direct connection.
No logs
No IP addresses, room IDs or payloads are recorded, in development or production.
The key never leaves the link
Encryption keys are generated in your tab and live in the part of the URL browsers never send to servers. Our relay forwards sealed bytes, not files.
