Privacy policy

Cost Doctor does not collect anything about you. It has no account, no analytics and no tracking. It reads log files that are already on your Mac and shows you what is in them.

What the app reads

The app reads the session logs that Claude Code and Codex keep on your Mac (~/.claude/projects and ~/.codex/sessions). It adds up token counts and reads session names and timestamps. This happens on your Mac. The logs, your prompts and your code are never sent to us or to anyone else.

What the app sends, and to whom

The app sends nothing to us. It makes a network request only in these cases, each of which you turn on:

• Phone alerts. If you paste an address in Settings, alert titles and short descriptions are sent to that address.
• Claude Code plan limits (version from this website only). If you click Connect, the app uses the Claude sign-in already saved on your Mac to ask Anthropic for your usage. The sign-in is sent only to Anthropic.
• Pull request checks (version from this website only). The app asks GitHub about your open pull requests through GitHub's own command line tool, using your existing GitHub sign-in.

Your settings, and your licence key if you have one, are stored in a folder on your Mac. The licence is checked on your Mac without contacting a server.

The Mac App Store version

The App Store version reads the two log folders only after you choose them in a macOS permission window. It does not read your Claude sign-in and does not contact GitHub. Purchases are handled by Apple; we never see your payment details.

This website

This website has no analytics scripts, no advertising and no tracking cookies. It is served by Cloudflare, which keeps standard server logs such as IP address and page requested. If you buy a licence here, the payment is handled by Stripe; we receive your email address so the licence can be issued to you, and nothing about your card.

Changes

If this policy changes, the new version will be posted on this page with a new date.
