Whir is a macOS menu-bar app that estimates the API-equivalent usage value of your local AI coding activity (Claude Code and Codex). It is designed to be private by construction.

What Whir reads

Whir reads only the local log files those tools already write on your Mac:

~/.claude/projects/** (Claude Code)
~/.codex/sessions/** (Codex)

Transcript lines may also contain prompts, generated code, and tool output. Whir parses matching JSON records in memory, but uses and caches only token counts, model names, timestamps, and project folder names to compute cost estimates. It does not display, store, or upload conversation content, and it never opens credential files such as ~/.codex/auth.json.

What Whir does NOT do

No data collection. No account, no server, no analytics.
No uploads. Nothing about you or your usage ever leaves your Mac. Whir's only network activity is an optional once-a-day download of its model price table (pricing.json) from GitHub — a plain file download carrying no personal or usage data (GitHub sees your IP address, as with any download). Turn it off in Settings and Whir works fully offline with its built-in prices.
No keychain / credential access. Whir never reads the macOS keychain or stored credentials.
No third parties. Nothing is shared with anyone, because nothing is collected or transmitted.

All processing happens entirely on your device. Results are stored only in a local cache on your own Mac (~/Library/Application Support/Whir).

Data retention & deletion

Whir stores nothing off-device. To remove all of Whir's local data, delete the app and its ~/Library/Application Support/Whir folder.

Verify it yourself

Whir is open source — you can read exactly what it does at github.com/yongjip/whir.
