Claudometer Privacy Policy

Effective: 16 May 2026

Claudometer (“the app”) is a small utility that shows your Claude.ai usage limits on your iPhone, iPad, or Mac. This policy explains exactly what data the app touches, where it goes, and what it doesn’t do.

In one sentence

Claudometer stores your Claude.ai session key in your device’s Keychain and uses it to read your usage from Claude.ai. Nothing else leaves your device.

What data Claudometer handles

Your Claude.ai session key. You provide this either by signing in to Claude.ai through a window embedded in the app, or by pasting it manually. The key is stored exclusively in the device Keychain (service com.claudometer.sessionkey), is not synchronised to iCloud, and is never transmitted anywhere except to claude.ai as a session cookie on the requests below.

Your Claude.ai usage data. The app reads your usage percentages and reset timestamps from Claude.ai. This information is cached locally so widgets and the menu-bar icon can display it quickly. The cache lives in your device’s Application Support folder and in shared App Group containers (group.com.Claudometer on macOS, group.com.Claudometer-iOS on iOS) read only by widget extensions belonging to the same app.

Your preferences. Refresh interval, notification thresholds, icon style, and similar settings are stored in standard UserDefaults on your device.

Where data goes

Claudometer makes HTTPS requests to two endpoints, and only these two:

• https://claude.ai/api/organizations — to learn which organisation your account belongs to.
• https://claude.ai/api/organizations/{id}/usage — to fetch your current usage limits.

Both requests carry your session key as a cookie. They are sent to Anthropic / claude.ai, not to any server operated by the developer of Claudometer.

What Claudometer does not do

• No analytics. No crash reporters. No telemetry. No third-party SDKs of any kind.
• No advertising identifiers, no fingerprinting, no tracking across apps or websites.
• No transmission of your session key, usage data, or preferences to any server operated by the developer.
• No collection of your name, email, location, contacts, photos, microphone, camera, or health data.

Permissions and entitlements

• Notifications (optional): used solely to alert you when your usage crosses the thresholds you configure, and when your five-hour session window resets.
• Background App Refresh (iOS, optional): used to refresh usage data so widgets stay accurate. The refresh only calls the two endpoints listed above.
• Keychain access: used to store the session key.
• App Groups: used by the widget extension to read the local cache.
• Network access (macOS): used only for the two HTTPS requests above. The app is sandboxed.

Claudometer does not request access to location, contacts, calendars, photos, camera, microphone, motion, or health data.

Children

Claudometer is not directed at children under 13 and does not knowingly collect any data from anyone.

Your control

You can sign out at any time from the app’s Settings, which removes the session key from your device’s Keychain. Deleting the app removes all local caches and preferences.

Affiliation

Claudometer is an independent project. It is not made by, endorsed by, or affiliated with Anthropic, PBC. “Claude” and “Claude.ai” are trademarks of Anthropic, PBC.
