Your work stays on your machine.

Loupe has no account and no server. It drives the Claude Code binary already installed on your computer, using your own subscription — your prompts and responses travel between you and Anthropic exactly as they do in the terminal, with nothing metered and nothing proxied through us.

The one exception is a small usage counter, so we can see how much Loupe is actually used. It runs in released builds, and everything about it is below — including the one way to switch it off.

What Loupe sends

Three events, each one just a name and a timestamp:

• App opened — Loupe launched.
• Session started — you began a new session.
• Message sent — you sent a message. The count, never the message.

Alongside them, four facts about your setup ride along once — not with every message: your Loupe version, your operating system and its version, your CPU architecture, and your Claude plan tier. That is the complete payload. It goes to Mixpanel on EU infrastructure, and only from packaged builds — development builds send nothing.

What Loupe never sends

• Your prompts, and Claude's responses.
• Your code, file contents, file paths, or working directories.
• Project names, branch names, or organisation names.
• Your location. Both requests explicitly tell Mixpanel not to derive one from your IP address, which it would otherwise do by default.
• Anything derived from any of the above.
• Your Claude credentials. Loupe never reads, stores, or transmits your login token.

How you are identified

By a SHA-256 hash of your Claude account email — never the address itself, so our analytics cannot be read as a customer list or leaked as one. If no email is available, because you are signed out or using an API key, a random ID generated on your machine is used instead.

This is pseudonymous rather than anonymous: someone holding the hash and guessing a specific address could confirm a match. It cannot be reversed in bulk or turned back into a list of people.

Turning it off

Set LOUPE_DISABLE_ANALYTICS=1 in the environment Loupe launches from. Nothing is reported, in this or any future version, and nothing else about the app changes.

There is deliberately no toggle inside the app. We would rather say that plainly than ship a switch and quietly hope you don't find it: the counts are how a one-person project decides what to build next, and a settings switch turns them into a measure of the least privacy-sensitive users instead of a measure of users. The environment variable is the honest version of the same promise — it always works, and it is the reason this page names it rather than burying it.

This website

loupecode.dev counts page views with Vercel Web Analytics: which page you landed on, the site that referred you, and coarse details like country, device type, browser and OS. It sets no cookies and does not follow you across other sites. The only thing stored in your browser is your light/dark preference, and only once you choose one.

Web fonts load from Google Fonts, the version badge reads the GitHub releases API, and downloads are hosted on GitHub — each of those sees your IP address, as any web request does.

Questions

Ask in the Loupe Discord. If this page and the app ever disagree, the app is the bug — tell us.
