Privacy policy
Somnus runs on your computer. It has no Somnus accounts, no analytics and no tracking. This page lists what it keeps on your computer and which services it contacts to do its job.
What stays on your computer
- Your Minecraft accounts. Your Minecraft username and ID, and the sign-in tokens Microsoft gives the launcher. Tokens are encrypted with your operating system's secure storage where it's available. Somnus never sees your Microsoft password; you type it on Microsoft's own sign-in page.
- Profiles, mods, worlds and settings, in the Somnus data folder.
- Your skin library and themes.
- Play time and performance sessions (frames per second, memory use and the server address you were on) so the launcher can show your stats. These never leave your computer.
Uninstalling Somnus and deleting its data folder removes all of it. On Windows the folder is %APPDATA%\Somnus; on Linux it's ~/.config/Somnus.
Services Somnus contacts
| Service | Why | What's sent |
|---|---|---|
| Microsoft, Xbox Live and Minecraft services | Signing you in, launching the game, changing your skin | Sign-in tokens, and the skin image when you upload one |
| Mojang (game downloads, skins, player lookup) | Downloading the game, Java and assets, and showing player skins | The files requested, and player names you search for |
| Modrinth | Browsing, installing and updating mods and modpacks | Search terms, your profile's Minecraft version, and file fingerprints when checking for updates |
| Fabric and Legacy Fabric | Installing the Fabric mod loader | The Minecraft version |
| Minecraft servers you add | Showing whether a server is online | A standard server status request |
Each of these services has its own privacy policy. Somnus sends them only what's needed for the action you took.
Children
Somnus doesn't collect personal information from anyone. Signing in uses your existing Microsoft account under Microsoft's own rules, including their family settings.
Changes
If this policy changes, the new version goes on this page with a new effective date, and the changelog mentions it.
