How it works

You need Node 22 or newer. Run the sync command — no global install required:

On first run, your browser opens to approve the device. After you approve, the CLI saves a long-lived sync token locally, scans ~/.claude/projects/, and uploads your aggregate totals.

Later runs reuse the saved token and upload only new data since the last sync — no browser step:

Useful flags and commands:

• --dry-run — show what would be uploaded without sending it
• --since=2026-06-01 — re-scan from a specific date
• doctor — diagnose what the CLI sees in your local logs
• status — show your last sync time
• unlink / logout — remove the local token

Your profile shows API-equivalent cost, active hours, billed tokens, session counts, model mix, and a day-level activity grid. The leaderboard ranks everyone by cost, hours, or tokens. Prompts, file paths, project names, email, and device details are never uploaded or shown — see the privacy page.

The sync CLI is MIT-licensed and public, so you can audit exactly what it does.
