About
All your files, finally together
BIShare exists so that moving and sharing your files across every device is one thing, in one app — not three.
The story
Why we built it
We started BIShare because moving a file between your own devices shouldn't require a cloud round-trip — and sending one across the world shouldn't mean a slow, clunky upload. Sharing with the person next to you was somehow harder than sharing across the planet.
So we built one tool for all of it. Move files at local speed when your devices are near, and send a link they open in any browser when they're far. Local speed, cloud ease — one app.
We wanted the digital equivalent of handing something over.

What guides us
Four things we won't compromise on
Private first
Encryption isn't a feature tier. Every transfer is end-to-end encrypted — always, for everyone.
Fast is a feature
Nearby transfers run at the speed of your network, on a transfer engine built in Rust and tuned byte by byte.
Quietly simple
The best sharing tool is the one you stop noticing. Fewer taps, fewer decisions, fewer surprises.
For every device
One app across iOS, Android, macOS, Windows, and Linux — available in 13 languages.
Privacy
Where your files go — and where they don't
The panel on the right is our whole stance in miniature — the policy itself is just as direct.
- Nearby transfers travel device-to-device and never touch a server
- Remote shares live on secure cloud infrastructure for 24 hours, then are deleted
- Everything is encrypted with AES-256-GCM and X25519 key exchange
- One-time links destroy themselves after a single download
- No ads, no tracking, no selling data — ever
Under the hood
Engineered, not assembled
BIShare runs on a custom transfer protocol written in Rust — zero-copy decoding, streaming encryption, adaptive chunking — shared by every platform we ship. The same engine that moves a 40 GB folder across your studio Wi-Fi also secures a 2 MB PDF on its way around the world. One codebase, five platforms, no compromises between them.
- zero-copy decoding
