Langprobe
Privacy
Self-hosted (default)
When you run langprobe yourself, your data stays on your infrastructure. The product does not phone home, does not ship telemetry, and does not relay traces to any langprobe server. Your ClickHouse, your Postgres, your retention.
OAuth sign-in
If your operator has configured Google or GitHub OAuth, signing in sends a redirect to that provider so they can authenticate you. Langprobe receives only your verified email, your name (if you share it), and a stable identifier. Nothing else is shared with the OAuth provider beyond what they already know about you. We do not store your provider password or token beyond the one-time exchange.
Hosted service
The hosted (SaaS) instance is on the roadmap. When it ships, this page will document data residency, retention, processor list, and DPA terms for hosted customers. Until then, all langprobe deployments are operator-run and operator-owned.
LLM credentials
Anthropic / OpenAI keys you save under workspace settings are stored hashed; the plaintext is shown once on creation and never again. Rotation is revoke-and-create, not edit-in-place.
