Privacy
Lumen is a desktop app that runs on your computer and edits files that already live on your disk. There is no server in the loop, and there is no account.
The short version
- Lumen does not require an account.
- Lumen does not phone home, track usage, or collect analytics.
- Your content, files, and project metadata never leave your computer.
- The only network requests Lumen makes are the ones you ask it to make, like publishing your site to your own hosting provider.
What Lumen reads on your computer
Lumen reads the project folder you open and writes back to those same files. That's the whole point: it's a CMS on top of files you already own. Lumen does not read other folders on your disk, browse your filesystem in the background, or scan your other applications.
Updates
The app checks for new versions by fetching a small JSON manifest from our update server. That request includes your current Lumen version and the operating system version, so we can serve a compatible build. It does not include a user identifier. You can disable update checks in Preferences.
Crash reports
If Lumen crashes, you'll see a dialog asking if you want to send the crash report. Reports are never sent automatically. If you opt in, the report contains a stack trace and the app version. No file contents, no project metadata.
Licensing (Pro)
Buying a Pro license creates a record on our side: your email, the license key, and the devices the key is activated on. We use this only to deliver the license, support renewals, and let you move the license between machines. We do not use it for marketing and we do not share it.
Third parties
Lumen publishes your site to whichever host you configure (for example Netlify, Vercel, Cloudflare, or a Git remote). Those services have their own privacy policies. Lumen sends only the data needed to deploy: usually a build artifact and a token you provided.
