Drag a file in, send it straight across.
Drop any file into Privatta and share it in seconds. It travels directly to the other machine — no upload to a server, no link that lingers in someone's inbox, no copy left behind.
- Real-time transfer speed and progress
- Works for any file type or size
- No third-party storage, ever
You decide exactly who can see what.
Share a file publicly on your LAN, with named people, or with a whole group. Bundle files into virtual folders that share one policy, so large sets stay organised and correctly locked.
- Per-user and per-group permissions
- Virtual folders with inherited rules
- Per-file descriptions for context
On the computer and in your pocket.
The desktop app runs on Windows and macOS. An Android companion app discovers machines on your network and browses and downloads shared files under the same access rules. iOS is in development.

- Saved devices for quick reconnection
Built for real teams, not just quick shares.
The details that make Privatta workable day to day — for one person or a whole organisation.
Virtual folders
Group related files under a single shared permission set so you manage access once, not file by file.
Public LAN shares
Offer files to everyone on your local network without setting up accounts — handy for a quick handoff.
Trusted networks
Pre-approve VPN address ranges (Tailscale, ZeroTier and the like) as trusted so remote teammates connect cleanly.
Saved devices
Remember the machines you connect to often and reconnect with one tap, on desktop or Android.
Server controls
Start, stop and watch your sharing server, with live status and your current public address at a glance.
Three editions
Free for quick LAN shares, Pro for private and internet transfers, Enterprise for group rules and audit.
Every feature, every edition.
Pro unlocks internet P2P and private access control. Enterprise adds user groups and organisation-wide permission hierarchies — no features are removed, only added.
