What z4j.com collects

This marketing website is static and hosted on Cloudflare Pages. It runs Google Analytics 4 for anonymous pageview and referrer counts. Nothing else third-party loads: no advertising tags, no cross-site tracking, no session replay.

Analytics storage starts denied. Visitors in the EEA, the UK, and Switzerland are shown a consent banner and nothing is stored until they accept; if we cannot determine the jurisdiction we show the banner. Elsewhere analytics storage is granted automatically and the banner does not appear. Your choice is remembered in your browser under the local-storage key z4j-consent, and you can change it by clearing site data for this domain. The site also stores your light or dark theme preference under z4j-theme.

Analytics data is processed by Google under their own terms. Cloudflare may log standard HTTP request metadata (IP, user-agent, timestamp) under their own privacy policy.

What z4j collects (self-hosted)

When you self-host z4j, its data lives in your infrastructure. z4j stores:

  • User accounts (email, name, argon2id password hash, sign-in and lockout details including the IP address of the last failed sign-in)
  • Sessions (the IP address and user agent each was issued to)
  • Task events (scrubbed of recognized secrets by the agent and again on ingest)
  • Audit log entries (admin actions and auth events, with source IP address and user agent)
  • Agent metadata (hostname, capabilities)
  • Notification channel settings, including their credentials and recipient addresses

None of this data is transmitted to z4j.com. It leaves your infrastructure only through integrations you configure, such as notification channels, the audit webhook, Sentry, or OpenTelemetry. You own your data.

Telemetry

z4j does not phone home. There is no telemetry, no usage reporting, no license-check call. z4j works fully air-gapped.
