# Privacy

*Effective October 4, 2026*

Claudoscope is a macOS app that shows you what Claude Code is doing, and it does that by reading files that are already on your Mac. This page covers what the app reads and writes, and what this website collects. Your sessions stay on your Mac.

## The app

### What it reads

Claudoscope reads the session transcripts Claude Code writes to `~/.claude/projects/`, your Claude Code configuration in `~/.claude/`, and Claude Cowork sessions in `~/Library/Application Support/Claude/`. It reads transcripts in place and never modifies them.

### What it writes

To launch quickly, Claudoscope keeps a cache of session summaries on your Mac. The cache is built from your transcripts, and you can delete it at any time. Claudoscope changes your Claude Code setup only through features you turn on yourself, such as security hardening or notifications. Each of these backs up your existing configuration first and can be reverted.

### What stays on your Mac

Claudoscope processes session contents, prompts, code, costs, and any secrets it detects in your transcripts locally, and it doesn't upload them anywhere. It has no telemetry, analytics, or crash reporting, and there is no account to create or sign in to.

### The MCP server

The MCP server is optional and off by default. Once you turn it on, it runs inside the app and answers Claude Code on your machine through a local socket that only your user account can open.

### Notifications

Alerts and session notifications are standard macOS notifications that your Mac delivers.

The site sets no cookies and runs no analytics. If you dismiss the announcement banner, your browser remembers that in its local storage, and the choice is never sent to a server.
