Privacy Policy — AI Usage Monitor for Mac
Short version: the app collects nothing, sends nothing, and needs no account.
What the app does
AI Usage Monitor for Mac shows how much of your ChatGPT Codex and Claude Code usage limits you have used, using files those tools already keep on your Mac.
What it reads
Only the folders you choose in the macOS open panel, read-only. From them it reads numbers and times — percent used, window length, reset time, plan name — and, for the recent-sessions list, a session id, the time span, the model name and the short display title Codex stores. While reading, the app may pass over details such as a session's working-folder path, but it does not show or store them. It does not read your prompts, responses, source code, file contents, login information, tokens, cookies or API keys, and it never edits those tools' files or settings.
What it sends
Nothing. The app has no network access (it does not have the network entitlement) and contains no advertising, analytics, tracking or third-party SDKs. No data leaves your Mac through the app.
What it stores, and where
On your Mac only, inside the app's sandbox container: a small cache of the latest numbers, a history file of numbers and times (no text you wrote), your settings, and the access grants (security-scoped bookmarks) for the folders you chose. Settings → General → Delete stored usage data (사용 데이터 삭제) removes the cache and history. Settings → Services → Disconnect (연결 해제) forgets a folder. After you delete the app, macOS may leave the app's sandbox container folder on disk, so to remove everything, delete the stored usage data and disconnect first, before you delete the app.
Data collected by the developer
None. There is no server, no account and no telemetry, so there is nothing to access, correct, export or delete on our side. Everything is on your device and under your control.
Notifications
Optional. If you turn on usage alerts, macOS asks for permission; alerts are generated on your Mac from the numbers above and are not sent anywhere.
Children
The app collects no personal information from anyone, including children.
Changes
If this ever changes we will update this page and the App Privacy details in the App Store before the change ships.
