The Floor
The home screen. A short list of your people, lit up green when they're around.
Fliporium
A private little room for you and your people.
A free Windows app for chatting and sharing files peer-to-peer with the handful of people you actually care about — no account, no tracking, end-to-end encrypted.
Windows 10 & 11 · no install, no account, no signup
What it is
Fliporium is a small desktop hangout for you and the few people you
actually care about — no signup, and no company sitting in the middle.
It's one portable .exe: keep it on a USB stick if you like,
and your identity and chat history travel with the file. Create a room,
share its invite link, and whoever has it connects straight to you —
device to device.
Five little things you can do here
Rooms
Make a room, share its link, and everyone who has it lands in the same private space to chat and trade files.
Flip a file
Drag a photo, a PDF, a song — anything — onto a friend's name. Sending a file is a flip; it lands straight on their disk.
Invite a friend
Copy your room's invite link and send it however you like. They paste it in and they're with you — nothing to sign up for.
Yours, end to end
Messages and files go directly between devices, sealed. We can't read them — we can't even see they happened.
That's the core. Once you're in there's also full-text search, reactions and edits, inline file previews, delivery for messages sent while you're offline, light and dark themes, and Twin Mode to keep a second device in sync. The docs walk through all of it.
Privacy isn't a feature
Most chat apps are a company sitting between you and your friends. Fliporium isn't a company — it's just an app.
Our server only introduces peers and relays the encrypted handshake. Your messages are sealed with a key that lives in the room's invite link and never reaches us, so even the parts that can pass through us — a message left for someone offline, a relay for a tricky network — are ciphertext we can't open. No file scanning, no “ML team,” no ads.
We do count completed downloads, just to see if anyone finds this useful. That number is public. More in the privacy notes.
