Every KVRNL app is free — but not anonymous. Downloads run through a free account so each install gets its own license key.
| 1. Create a free account | Email verification and nothing else. No card, ever. → kvrnl.io/signup |
| 2. Claim your key | One click per product. Instant. |
| 3. Download and install | Straight from GitHub Releases. |
| 4. Switch machines anytime | Keys bind to one device. Hit Release device on your account page to move it. |
These repos host releases and licenses — the application source code is closed and not published here.
GitHub Issues are disabled. Report bugs from inside the app; they reach us directly. Everything else goes through Discord or kvrnl.io/contact.
Every app ships under the same KVRNL Software License: proprietary freeware. Free to use, not open source.
KVRNL apps send us only what's needed to check your license key — the key, the product name, and a hardware ID. No telemetry, no analytics, no tracking, and none of your files. Read the full policy at kvrnl.io/privacy.
