Privacy Policy

JevRail is an open-source CLI tool plus this marketing and documentation website. There is no account system and no hosted service that stores your data — this policy covers only what the website itself does, and points to where the CLI's own data handling is documented.

This website

This site (jevrail.samanp.xyz) is a static marketing and documentation site. It uses Vercel Analytics to collect anonymous, aggregated page-view metrics (pages visited, referrers, rough device/browser type), and PostHog for the same kind of aggregate traffic measurement plus counts of a few interactions — clicking "Star on GitHub", clicking "Share on X", and copying a code block. PostHog is loaded from us.i.posthog.com. None of it is tied to your name or email, isn't sold, and isn't shared with advertisers. We never call identify(), so no profile is ever created for you and no cross-session identity is built. We don't set any tracking cookies, and there is no login, form submission, or account creation on this site beyond the optional email link on the Contact page.

The CLI tool

The jevrail CLI runs entirely on your own machine. Depending on your configuration, it may send a redacted version of the command you're about to run — plus compact repository context — to the Jev decision model over the network, so it can return a safety verdict. Exactly what is and isn't sent, how secrets are redacted, and how to run fully offline (no_model=true) is documented in detail in the CLI's Privacy doc. We don't receive or store any of that data ourselves — it goes directly from your machine to the model provider you configure.

What we don't collect

We don't sell data, run ad trackers, or use anything from this site or the CLI to train models.

Third parties

This website is hosted on Vercel, which also provides the anonymous analytics above. PostHog (post-hoc data platform) receives the anonymous traffic and interaction counts described above. The CLI talks directly to whatever base_url you configure (TypeSafe AI's Jev API by default, or a self-hosted compatible endpoint) — see the docs for details.

Changes to this policy

If this policy changes materially, we'll update the date at the top of this page.
