Nobody can push
a file at you.
Files that land on a machine by themselves are how machines get ruined. So a security code lets somebody reach you — it never lets them write to you. That takes your approval, once, per person.
1
Everyone gets a code
Sixteen characters, generated for you, never chosen. Share it like a phone number. Roll it the moment it leaks — the old one dies instantly.
2
Email plus code opens a request
That pair finds a person and asks to connect. It does not move a single byte. Wrong guesses are rate limited and look identical to misses, so codes cannot be fished out.
3
You approve, once
After both sides agree, files flow. Auto-download runs only for approved contacts, skips anything executable, and honours a size ceiling you set.
4
The server never sees your files
Every file is sealed with a one-time key on your device before upload. That key is wrapped for the recipient alone. Storage holds ciphertext and a checksum, nothing readable.
Built for teams
that move fast.
Inbox or straight to disk
Choose per contact. Trusted teammates land in a folder; everyone else waits in an inbox until you say so.
Relayed, then wiped
Files pass through in chunks and are deleted once collected. The relay is a corridor, not a filing cabinet.
Team spaces
Group your people. Drop a file once and it reaches everyone approved in the space.
Verified on arrival
Every transfer carries a SHA-256 checksum, recomputed after decryption. A mismatch is refused, not opened.
Works away from the office
No shared network needed. If both machines can reach the internet, they can reach each other.
Your space.
Database not set up yet
Run supabase/schema.sql in the Supabase SQL editor, then reload. Sign in works, but contacts and transfers need the tables.
Your security code
Give this with your email so somebody can ask to connect. It never lets them write to your devices on its own.
