Privacy
Your code stays on your machine.
Kairn keeps its index and session data in your project's .kairn directory. Normal use does not send your code, prompts, diffs, file paths, or agent output to Kairn.
What stays local
Kairn reads and indexes the repository on your machine. It does not require a Kairn account, API key, or hosted Kairn service. Your coding agent still follows its own provider's data practices.
Optional telemetry
Telemetry is off until you enable it. It contains aggregate counts about usage, reliability, response time, and context efficiency. It does not contain your source code, prompts, file paths, or raw agent output.

Diagnostic bundles are created locally. You can inspect a bundle before choosing to share it; Kairn does not upload it automatically.
This website
This site uses Vercel Analytics for aggregate website measurement. If you sign up to help improve Kairn, the contact and optional details you submit are stored in Supabase and used for product updates and feedback follow-up. Website analytics and form submissions are separate from your local Kairn data.
