What’s inside

Built for people who actually care about privacy

Every feature was designed with one rule: your data never leaves your device.

P2P Transfer
Encrypted file transfer directly device-to-device over Iroh. No cloud, no middleman, no relay. The file goes from you to them and nowhere else.
QUIC • TLS 1.3 • No relay
Ghost
Hide encrypted messages inside plain text using zero-width Unicode steganography. Invisible to anyone who isn’t the recipient. Nothing is stored.
X25519 • ChaCha20-Poly1305 • Zero-width
Camera Shield
YOLOv8 AI detects phones pointed at your screen in real time. When one is found, the screen blacks out instantly. 100% local — no frames ever leave your device.
YOLOv8 • On-device • <100ms
Library
Encrypted personal vault with full-text search, OCR, and tagging. Files vanish when ZRO closes. Nothing persists between sessions — no traces left behind.
SQLite • Tantivy • Session-only
Our commitment
Privacy is not a feature.
It is the foundation.

Every design decision, every line of code, every default — made with one principle: your data is yours and nobody else’s.

Zero Telemetry Zero Servers Zero Accounts Zero Logs Open Source
Who built this

Not a company. Not a government. Just one person.

ZRO was built by a single independent developer based in Switzerland — a country with some of the strongest privacy laws on Earth. No team. No investors. No hidden agenda.

I built ZRO because I got tired of every app quietly logging what I do, who I talk to, and what files I keep. Privacy isn’t paranoia. It’s a basic right — and it’s being eroded quietly, every day.

ZRO runs entirely on your device. It never phones home. There are no servers to subpoena, no accounts to breach, no logs to leak. I can’t see your data. Nobody can.

If you’re wondering whether to trust it: that’s exactly the right instinct. Don’t trust any app blindly — including this one. Run it offline. Read the code. It does what it says.

Swiss-based
Built and hosted under Swiss jurisdiction — home to the strongest privacy laws in Europe. GDPR-plus protections, no backdoors, no foreign data-sharing agreements.
No server, no logs
ZRO has no backend. No database to breach, no logs to subpoena, no telemetry to sell. Your messages and files never leave your device unless you send them — peer-to-peer, end-to-end encrypted.
1 developer, no team
No VC funding. No board. No investors asking for growth metrics. One person who wanted this tool to exist — built it, uses it, maintains it. The only agenda is yours.
