Aletheia collects nothing. It has no telemetry and makes no network requests. Your memories stay in your project, on your machine.

The software

This covers the aletheia binary, its MCP server, the Claude Code plugin, and the npm, Scoop and Homebrew packages that install it.

Memories are Markdown files in your project's .aletheia/ folder. You decide whether to commit and share them.
To check memories against the code, Aletheia reads your project's files. It never reads outside the project root, and anchors never execute anything.
With the Claude Code hooks, it reads the prompt you send and, when a task ends, the session transcript file that Claude Code names, to record which files the task changed. That record is a memory in .aletheia/, labelled with the task's prompt shortened to 140 characters, so avoid putting anything private in prompts you don't want kept in the project. All of it stays on your machine.
The one program it starts is git check-ignore, during aletheia init.
Downloading it through npm, GitHub, Scoop or Homebrew is covered by those services' own policies.
