Privacy Policy — Kindex

# Privacy Policy

Last updated: March 24, 2026

The short version: Kindex is a local-first tool. Your data stays on your machine. We don't collect it, transmit it, or have access to it.

## What Kindex Is

Kindex is an open-source, local-first knowledge graph that runs entirely on your computer. It stores data in a local SQLite database in your home directory. It operates as a CLI tool and MCP server — there is no cloud service, no account system, and no server infrastructure.

## Data We Collect

None. Kindex does not collect, transmit, store, or process any user data on external servers. All data remains on your local filesystem under your control.

## Data You Create

When you use Kindex, you create a local knowledge graph containing nodes, edges, tags, and session metadata. This data is stored in:

- A SQLite database in `~/.kindex/` (or a project-local `.kin/` directory)
- Optional export files you explicitly create

This data never leaves your machine unless you explicitly copy, share, or publish it yourself.

## Third-Party Services

Kindex does not communicate with any third-party services. It does not make network requests. It does not phone home, check for updates, or transmit telemetry.

When used as an MCP server within Claude Code or Claude Desktop, the host application (Anthropic's Claude) may process the tool responses according to its own privacy policy. Kindex itself does not control or participate in that processing.

## Claude Code Plugin Context

When Kindex is used as a Claude Code plugin, the MCP tools return text content to the Claude session. This content is processed by Anthropic according to the Anthropic Privacy Policy. Kindex has no visibility into or control over what happens after tool responses are returned to the host.

## Analytics and Tracking

This website (kindex.tools) is a static site hosted on GitHub Pages. It does not use cookies, analytics, tracking pixels, or any third-party scripts. GitHub Pages may collect standard server logs per GitHub's privacy statement.

## Data Retention and Deletion

Since all data is local, you have complete control over retention and deletion. Delete the `~/.kindex/` directory and all data is gone. There is nothing to request from us because we don't have anything.

## Children's Privacy

Kindex does not collect personal information from anyone, including children under 13.

## Changes to This Policy

If Kindex ever adds cloud features or data collection, this policy will be updated before those features ship. The current architecture is local-only by design, not by oversight.
