You look up — your bag is open and the laptop is gone. You open Ervun and hit Lock. Ten seconds later it's a sirening brick flashing your phone number, wherever it is.
Remote lock + alarmErvun is a zero-knowledge anti-theft and remote-control system for the devices you own. Lock, locate, capture, transfer files, and wipe — all from your phone. Your passphrase never leaves your hands.
Install a tiny agent on your PC. Enroll it with a one-time code. From that moment, your phone can lock it, find it, see it, and wipe it — from anywhere on Earth. And because everything is sealed with keys only you hold, nobody else can. Not thieves. Not hackers. Not even us.
One day your stomach will drop. Here's how that day goes with Ervun on your phone.
You look up — your bag is open and the laptop is gone. You open Ervun and hit Lock. Ten seconds later it's a sirening brick flashing your phone number, wherever it is.
Remote lock + alarmThe deck you finished at midnight is on the PC at home. You browse its drive from your phone and pull the file. It arrives encrypted end-to-end — before your coffee cools.
Secure file transferDid you leave the studio PC rendering? One tap on Screenshot and you're looking at its screen from 300 km away. All good. Sleep easy.
Screenshot & webcamThis is a live simulation of Ervun. Send a command from the phone and watch it cross the relay to the laptop. Flip on Server X-ray to see the only thing our relay ever sees.
A simulation — no real devices were harmed. The real thing works exactly like this, from anywhere.
Your account stores only ciphertext — no passwords to hand over, no data to trust us with. You install, you enroll, you command.
Download the signed Ervun agent onto your Windows PC and run it. One click — no Python, no setup, no fuss.
Download for WindowsOpen the app, generate a one-time code, and type it into the agent. The code is locked to that machine's hardware ID — it can't be replayed anywhere else.
Lock, locate, capture, transfer, or wipe — instantly. Every destructive command is signed on your phone before your device will trust it. You just tried it above.
Ervun's relay is deliberately blind. Your passphrase becomes keys on your device, everything is encrypted before it leaves, and destructive commands are signed with your private key.

Lost your laptop? Left a file behind? Want to check in? Ervun turns your phone into a remote for the devices you own.
Instantly lock a stolen or misplaced device and blast an on-screen message and alarm so it can't be used or ignored.
Find where a device is right now, so you know whether it's down the couch or across town.
Capture a screenshot or a webcam photo on demand — see exactly what's happening, or who has it.
Pull a file you forgot from your PC, or push one to it — chunked and encrypted end-to-end, both ways.
Captures and transferred files land in a vault only your passphrase can open. Not us. Not anyone.
Send a message straight to a device over a secure channel — leave a note for whoever finds it.
PremiumQueue actions to run later, or on a delay — control that works even when the device is offline right now.
If a device is truly gone, wipe it. The command is cryptographically signed by you — no one else can trigger it.
Every command and result, timestamped. Know what was done, when, and whether it landed.
Get the controller app on your phone, then install the agent on each PC you want to protect.
Your command center — enroll devices, send commands, browse your vault, and manage everything. Coming soon on Android; iOS to follow.
Runs quietly on each PC you own, executing your signed commands. One click to install — no Python, no fuss.
