Build with trust

Everything you need to install, verify, and understand agent skills. Security scanning, cryptographic signing, and full transparency.

This policy covers what data the Vett CLI and website ("Vett", operated by Vett Software Inc.) collect, why we collect it, and how to opt out. We keep it short because there isn't much to disclose.

Effective February 6, 2026

Information We Collect

Two categories, both minimal by design.

CLI Telemetry (opt-out)

When telemetry is enabled, the CLI sends the following on each command invocation:

deviceId
Random UUID, not tied to any account or identity
command
Command name (e.g. install, search)
duration
Execution time in milliseconds
success
Whether the command succeeded or failed
error
Error class name if failed (not the message)
cliVersion
Installed CLI version
os / arch / nodeVersion
Platform information

Website Analytics

We use PostHog for page view and feature usage analytics on the website. Skill download events are recorded to measure registry usage.

Cookies

PostHog sets a first-party analytics cookie to distinguish unique visitors and maintain session context. No third-party advertising or cross-site tracking cookies are used.

What We Don't Collect

We want to be explicit about this.

×Source code or file contents
×Skill content or instructions
×Filenames or directory structures
×Credentials, tokens, or API keys
×Personal information (name, email, etc.)
×Git history or repository metadata

How We Use It

Telemetry helps us build a better tool.

We use collected data to understand CLI version distribution across the user base, monitor error rates and fix bugs, track skill popularity to improve the registry, and make informed decisions about what to build next. We do not sell data to third parties or share it for cross-context behavioral advertising.

Third-Party Services

Services that process data on our behalf.

PostHog—Analytics
AWS / Vercel—Hosting and compute
Cloudflare—DNS and object storage

Opting Out

CLI telemetry is entirely optional.

Disable CLI telemetry

Set telemetry.enabled: false in ~/.vett/config.json, or set the environment variable VETT_TELEMETRY_ENABLED=0.

When telemetry is disabled, the CLI sends zero network requests for analytics. No data is queued or sent later.

Opting out disables CLI usage telemetry only. It does not affect standard server-side logging, rate limiting, or abuse prevention — those are required to operate the service.

Your Rights

Depending on where you are, you may have rights under privacy legislation such as Canada's PIPEDA, the EU's GDPR, or California's CCPA — including the right to access, correct, or delete personal data we hold about you. Given that we collect minimal, largely anonymous data, there may be little to action, but we respect these rights regardless. Contact privacy@vett.sh and we'll respond within 30 days.

Changes

We may update this policy as the product evolves. Continued use of the service after changes constitutes acceptance. For material changes, we'll make reasonable efforts to provide notice.
