> RDMBench keeps everything on the bench computer. The only requests it makes, what they carry, and how to turn them off.

- **Runs on:** macOS 15 Sequoia or later, Apple silicon
- **Needs:** An Enttec DMX USB Pro with its DMX/RDM firmware (major version 2)
- **Price:** Free

RDMBench is local. Reports, monitoring sessions and repair notes are
files on the bench computer, and the app works fully offline. It has no
analytics, no telemetry and no crash reporting.

## What it sends, and when

| Request | When | What it carries | Turn it off |
|---|---|---|---|
| App updates: `updates.rdmbench.com/appcast.xml` | Once a day | Nothing about your fixtures | Settings → General → Updates |
| Fixture library: a manifest on `raw.githubusercontent.com` | When you connect | Nothing about your fixtures | Settings → General, or the Connect sheet |
| GDTF Share: `gdtf-share.com` | Only if you sign in with your own account | Your sign-in, and the fixture you look up | Don't sign in |

- An **update** is downloaded only when you accept it.
- Changed **library tables** are downloaded only when you click
  **Update** in the banner that offers them.
- The GDTF Share password is kept in the macOS Keychain. There is no
  shared account and no RDMBench server in between.
- **Propose…** and **Contribute Fixture Profile…** open a prefilled
  pull request in your browser, for you to read and send yourself.

## AI assistants

Connecting an assistant sends nothing anywhere. The MCP server runs on
the bench computer and talks to the app over a loopback address. What
the assistant reads then goes to its provider as part of your
conversation ([Assistants](/assistants/)).

## Where your data is

Everything is under `~/Library/Application Support/RDMBench`:

- `captures/`: the reports and monitoring sessions, one folder per unit;
  simulator runs in `captures/simulator/`;
- `manufacturer-pids/`: library tables you have downloaded;
- `gdtf/`: GDTF files you have added.
