About this app

Ervun turns your phone into a secure remote for the Windows PCs you own. Lost your laptop? Left a file behind? Need to lock a machine right now? Do it in a tap — with encryption so strong that not even we can read your data.

ZERO-KNOWLEDGE BY DESIGN
Your passphrase never leaves your device. It becomes encryption keys on your phone, and everything sensitive — your captures, your files, your keys — is encrypted before it ever reaches our servers. We store only ciphertext. Even a fully compromised server can't read your data, unlock your machine, or wipe it. Only you can.

WHAT YOU CAN DO
• Remote lock & alert — instantly lock a stolen or misplaced PC with an on-screen message
• Locate on demand — find where a device is right now
• Screenshot & webcam — capture what's on screen, or a photo from the camera
• Secure file transfer — pull a forgotten file from your PC or push one to it, encrypted both ways
• Encrypted vault — captures and transfers land in a vault only your passphrase can open
• Device messaging — leave a note for whoever has the machine
• Scheduled commands — queue actions to run later (Premium)
• Remote wipe — if a device is truly gone, wipe it; the command is cryptographically signed by you, so no one else can trigger it
• Full activity log — every command and result, timestamped

FOR DEVICES YOU OWN
Ervun is a consent-based anti-theft and remote-control tool for computers you own or are authorized to manage. Each device is enrolled with a one-time code and your explicit consent. It is not for monitoring other people.

HOW IT WORKS
1. Install the free Ervun agent on your Windows PC (one click)
2. Enroll it with a one-time code from the app
3. Control it from anywhere

Fingerprint unlock. No trackers. No ads. Your keys, your data, your control.
