What Tokamak Does
Tokamak is a macOS menu bar app that displays your Claude subscription quota. It reads your usage data from claude.ai and local Claude Code files on your Mac.
Data We Collect
None. Tokamak does not collect, transmit, or store any data on external servers. There is no telemetry, analytics, crash reporting, or tracking of any kind.
Data That Stays on Your Device
| Data | Purpose | Storage |
|---|---|---|
| Session cookie from claude.ai | Authenticate with claude.ai to read your quota | macOS Keychain (encrypted by the OS) |
| Organization ID | Build the URL to fetch your quota | macOS Keychain |
| Usage data (quota percentages, reset times) | Display in the menu bar and popover | Core Data (App Sandbox container) |
| Claude Code session stats | Display token counts and session history | Core Data (App Sandbox container) |
| Achievement unlock dates | Track which achievements you’ve unlocked | UserDefaults (App Sandbox container) |
| Notification preferences | Remember which alerts have been sent | UserDefaults (App Sandbox container) |
All data resides exclusively on your Mac within the App Sandbox container. Nothing leaves your device except the single network request described below.
Network Requests
Tokamak makes exactly one type of network request:
- Destination:
claude.ai(Anthropic’s servers) - Purpose: Read your quota utilization (GET request)
- Frequency: Every 30 seconds when the app is active, with exponential backoff on errors
- Authentication: Your existing claude.ai session cookie
- Data sent: Your session cookie and organization ID (both already known to claude.ai)
- Data received: Quota percentages and reset timestamps
Tokamak does not contact any other server. There is no update check, no analytics endpoint, no crash reporter, no CDN. You can verify this with any network monitor — the only destination is claude.ai.
Local File Access
When you grant permission (via the macOS file picker), Tokamak reads files from ~/.claude/ on your Mac:
stats-cache.json— Aggregated Claude Code statisticsprojects/*/session.jsonl— Session token counts
These files are generated by Claude Code and read locally. Their contents never leave your device.
Third-Party Services
Tokamak does not integrate with any third-party service, SDK, or library that collects data. There are no ads, no social SDKs, no Firebase, no Sentry, no Mixpanel, no anything.
Children’s Privacy
Tokamak does not collect any data from any user, including children.
