Privacy Solon collects nothing
No account, no telemetry, no analytics, no crash reporting. This page says exactly what leaves your PC, which is almost nothing, and where the rest is kept.
What Solon sends
The Solon background service makes no outgoing network request of any kind. Not one.
The desktop application makes exactly one, and only while you leave it enabled: it asks github.com whether a newer version of Solon has been published. That request carries no identifier, nothing about you and nothing about your machine — it is the same request your browser makes by opening the releases page. Turn it off in Settings → Updates and Solon stops asking.
If you press Install update, the application then downloads that release's installer from github.com and checks its SHA-256 against the checksums published beside it. Nothing is sent in the other direction.
What Solon keeps, and where
Everything stays on your PC, under C:\ProgramData\Solon: the engine's data disk holding your images, containers and volumes; your settings; the local certificate authority used for the https://….solon.local addresses; and log files.
The log files record what the engine does, including the paths of the Windows folders you share with containers. They never contain credentials, environment variable values, or anything from inside your containers.
Uninstalling Solon leaves that folder in place unless you ask for it to be removed, and even then it is moved aside rather than deleted.
The diagnostic export
Settings → Diagnostic writes a zip file on your disk: logs, engine state, your settings, the system prerequisites and docker info. It is created only when you press the button, it is never sent anywhere automatically, and you decide whether to attach it to a bug report.
Your containers
Containers reach the internet as they would under any container engine: pulling images from the registries you name, and whatever the images themselves do. That traffic is governed by what you run, not by Solon, and Solon neither inspects nor records it.
No account, no third parties
Solon has no sign-in, no licence server and no paid tier. No advertising identifier, no analytics library, no third-party service embedded in the application.
