§ 0 The short version
The Halton Meter daemon runs entirely on your machine. It writes to
~/.halton-meter/ and nowhere else. No LLM request data,
no cost figures, no project names, and no API keys ever leave your
machine as a result of installing or running this product.
This is the point of the product.
The website (haltonmeter.com) has no analytics, no cookies, no tracking pixels, and no third-party scripts. It is a static page.

§ 1 What the product collects
Local SQLite, loopback only
The Halton Meter daemon is a local network proxy. It intercepts
outbound LLM API calls from processes on your machine, logs metadata
about those calls (timestamp, model, token counts, latency, computed
cost, project attribution), and writes that data to a SQLite database
at ~/.halton-meter/db.sqlite.
This data never leaves your machine. The daemon does not send telemetry, usage statistics, or any other data to Halton Labs or to any third party. The local HTTP API (default port 8765) is bound to loopback only and is not accessible from outside your machine.
If you choose to install the optional cloud dashboard (a separate product, not yet publicly available), a separate privacy policy will govern what that product transmits. The daemon itself does not participate in that transmission.
§ 2 What the website collects
Nothing.
haltonmeter.com is a static page served over HTTPS. It sets no cookies, loads no third-party scripts, runs no analytics, and makes no tracking requests. Cloudflare (our CDN and DNS provider) processes each HTTP request to serve the page. Cloudflare's own privacy policy governs what Cloudflare retains at the network level; we do not receive individual visitor data from Cloudflare.
If you contact us by email, we receive your email address and the contents of your message. We use it to respond. We do not add it to a mailing list or share it with anyone.
§ 3 API keys and credentials
Keys pass through; we do not retain them
The daemon routes traffic through a local proxy but does not log, store, or inspect API keys. Your keys remain in the environment or credential store where your LLM client reads them. They pass through the proxy in request headers in the normal way; the proxy does not extract or retain them.
§ 4 Children
Not for under-16s
This product is intended for developers and technical teams. We do not knowingly collect any information from anyone under 16.
§ 5 Your rights
Local data, local control
Because the daemon stores all data locally on your machine, you
already have complete control over it. To delete your data, delete
~/.halton-meter/. To inspect it, open the SQLite file
directly or use halton-meter report.
If you have contacted us by email and want us to delete your message, email operator@haltonlabs.com and we will do so.
§ 6 Changes to this policy
Material changes get a date bump
If we make material changes, we will update the effective date above and note the change in the product changelog. Continued use of the product after a material change constitutes acceptance of the updated policy.
