QEMU Manager has no analytics, no telemetry and no account. It goes online for two things only: checking your license key, and, when you ask, looking for QEMU updates.
Last updated: November 11, 2026
Release builds verify your license key with Gumroad's API (api.gumroad.com). The request contains the product ID and your license key, nothing else.
This happens on first activation, then about once a week. Gumroad receives your IP address as part of any network request and processes it under its own privacy policy.
To bind the activation to one computer, the app stores a salted hash of the operating system's machine ID in a local file. That hash is never sent anywhere.
When you open the QEMU page or click Check for updates, the app looks up the latest QEMU release:
formulae.brew.sh).qemu.weilnetz.de).These are plain page downloads; no information about you or your VMs is sent.
No analytics, crash reporting or usage tracking. The app does not send your name, email, VM names, VM configurations, disk images, console contents or file paths to Aleph Void or anyone else.
The embedded console, VNC and QMP connections listen only on loopback or a private local socket, and the VNC password changes on every boot.

Gumroad handles payment and receives the details you give at checkout. Aleph Void receives the order details Gumroad shares with sellers, such as your email address, and uses them only to provide support and deliver your license.
This site is hosted on GitHub Pages and loads fonts from Google Fonts; both receive standard request data such as your IP address. The site sets no cookies and runs no analytics.
