Pilot builds are unsigned

These builds are unsigned while we're in early pilot. Your OS may warn you on first launch.

macOS: Right-click the app → Open → click Open in the Gatekeeper dialog. You only need to do this once.

Windows: If SmartScreen appears, click More infoRun anyway.

Signed builds with Apple notarization will ship before public launch.

What the desktop app does

Passive activity tracking

Watches which app is in focus and for how long. App name only — no window titles, no file contents, no screenshots.

Time entry suggestions

Been in Westlaw for an hour? It drafts a time entry for your review. You approve, edit, or dismiss — nothing hits billing without your sign-off.

Matter attribution

Link app sessions to open matters. Cardboard learns which apps you use for which clients over time.

Privacy by design

All processing is local. App name only — no content, no screenshots. Opt out any time from settings.

Pilot release · Requires an active Cardboard Legal account
