Privacy Policy

Last updated: 2026-07-23

This policy covers the @almostjacked/fitness-tools library, the @almostjacked/fitness-tools-mcp MCP server (local stdio, the Claude Desktop extension, and the hosted connector at fitness-tools-mcp.ajwallacemusic.workers.dev), and the reference HTTP API.

Data collection

We do not collect, store, or share any personal data.

The calculators are stateless, deterministic functions. Inputs you provide (such as weight, height, age, or logged intake) are used only to compute the result of the call that contains them, and exist only for the duration of that call.

• No accounts. Nothing to sign up for; no identifiers are created.
• No storage. No database, no server-side persistence of inputs or results.
• No logging of inputs. The hosted connector does not record request bodies. Cloudflare, the hosting platform, processes requests to serve them and may record standard operational metadata (such as request counts and IP-level traffic data) per the Cloudflare privacy policy.
• No third-party sharing. Your inputs are not sent to anyone. The local (stdio / desktop extension) versions run entirely on your machine and make no network calls.
• No retention. Because nothing is stored, there is nothing to retain or delete.

Health data

Inputs may include health-related measurements (body weight, body fat, calorie intake). These are processed in memory to produce the calculation result and are never stored or transmitted onward.
