## 💾 Installation
### Option 1: Download Pre-built (Recommended)
1. Go to [Releases page](https://github.com/f-is-h/Usage4Claude/releases)
2. Download the latest `.dmg` file
3. Double-click to open, drag app to Applications folder
4. Right-click the app and select "Open" on first launch (allow unsigned app)
5. Allow Keychain access for authentication info (you may need to allow again after version updates; the prompt shows the relevant authentication token name)
> **Updates after the first install are in-app.** Sparkle checks for new versions automatically (and on demand via Menu → Check for Updates), then downloads, verifies the EdDSA signature, and installs with one click — no need to re-download the DMG for future releases.
### Option 2: Build from Source
#### Requirements
- macOS 13.0 or later
- Xcode 15.0 or later
- Git
#### Build Steps
```bash
# Clone repository

## ❓ FAQ
Q: What if the app shows "Session Expired"?
A: Claude Session Keys or Codex authentication tokens expire periodically (usually weeks to months), and you need to log in again:
1. Open Settings → Authentication
2. For Claude, click "Browser Login" to log in again (recommended), or manually re-obtain Session Key
3. For Codex, click Codex "Browser Login" and log in to ChatGPT in the built-in browser
4. Done, monitoring will resume
Q: How to enable auto-launch on startup?
A: Two methods:
**Method 1: Using built-in option (Recommended)**
1. Open Settings → General
2. Check "Launch at Login" option
**Method 2: Via System Settings**
1. Open System Settings → General → Login Items
2. Click "+" to add Usage4Claude
Q: How much system resources does it use?
A: Very lightweight:
- CPU Usage: < 0.1% (idle)
- Memory: ~20MB
- Network: Refreshes at the configured smart frequency; when both Claude and Codex are configured, each service is requested separately
Q: Which macOS versions are supported?
A: Requires macOS 13.0 (Ventura) or later. Supports both Intel and Apple Silicon (M1/M2/M3/M4/M5) chips.
Q: Why does it need Keychain permission?
A:
- Keychain is macOS's system-level password manager
- Claude Session Key and Codex authentication token are encrypted in Keychain
- Claude Organization ID is stored in local config (non-sensitive identifier)
- This is Apple's recommended secure storage method
- Only this app can access the information, other apps cannot view it
Q: Is my data safe? How is privacy protected?
**Completely safe!**
**Data Storage:**
- All data stored **only** on your local Mac
- No collection, no tracking, no statistics of any information
- No network requests except Claude and Codex usage-related API calls
- No third-party services used
**Authentication Security:**
- Claude Session Key and Codex authentication token encrypted via macOS Keychain (system-level encryption)
- Keychain uses AES-256 encryption + hardware protection (T2 / Secure Enclave)
- Only this app can access your credentials, other apps cannot read them
- You can revoke access anytime via "Keychain Access" app
**Code Transparency:**
- 100% open source
- No obfuscation or hidden features
- Community can audit and verify
**Additional Protection:**
- App Sandbox enabled (limits system access)
- No access to your files, contacts, or other apps
- Minimal permissions (only network + Keychain)
You can verify all of this by reviewing the source code on GitHub!
Q: Does it work with Claude Code / Desktop App / Mobile App?
A: **Yes, it works with all Claude platforms!**
Since all Claude products (Web, Claude Code, Desktop App, Mobile App, Cowork) share the same usage quota, Usage4Claude monitors your combined usage across all platforms.
Whether you're:
- Coding in terminal with `claude code`
- Chatting on claude.ai
- Using the desktop app
- Using mobile apps
- Using Cowork agents
You'll see your real-time total usage in the menu bar. No platform-specific configuration needed!
Q: How do I enable Codex support? Can I use Codex only?
A: Yes. Open Settings → Authentication, click Codex "Browser Login", and log in to ChatGPT in the built-in browser.
- Codex only: the menu bar and detail window show Codex usage
- Claude + Codex: the detail window shows both providers side by side
- Codex currently supports browser login only, not manual Session Key input
Q: Can't see the icon in menu bar?
A: macOS system or third-party software (like Bartender, Hidden Bar, etc.) may automatically hide menu bar icons.
**Solution:**
1. Hold **Command (⌘) key**
2. Drag icons in the menu bar with mouse
3. Drag Usage4Claude icon to the visible area on the right side of menu bar
4. Release mouse
**Note:**
- macOS Sonoma (14.0+) automatically hides infrequently used icons to "Control Center"
- You can adjust menu bar icon display in "System Settings" → "Control Center"
Q: How to manage multiple accounts?
A: Usage4Claude supports multiple Claude accounts, multiple organizations under the same Claude account, and independent Codex account management:
- **Add Account** - Add via Claude browser login, Claude manual input, or Codex browser login in Settings → Authentication
- **Switch Account** - Click "…" menu in detail window or right-click menu bar icon, select the Claude / Codex account to switch to
- **Edit Alias** - Set easily recognizable aliases for each account
- **Delete Account** - Swipe left or use edit mode to remove unwanted accounts
Q: How to enable usage notifications?
A: Toggle Claude usage notifications in Settings → General:
- **Usage Warning** - System notification when Claude usage reaches 90%
- **Reset Notification** - Notification when Claude quota resets
- macOS notification permission required on first enable
