 ## Usage reporting
 
-Usage reporting is on by default: FishE sends a `startup` event once per launch and a `save-loaded` event each time a save slot is created or opened to [trace](https://github.com/Stephenson-Software/trace) at `https://trace.danielstephenson.dev`, each carrying only the program name (`FishE`), the version from `version.txt` and a random installation ID (the tag `install`, so installations can be counted rather than launches). Nothing about you or your run is sent — no username, hostname, IP address, path, slot number or save contents. The in-browser front-end (`UIType.PYODIDE`) is silent: the game runs in your tab, where the client's background thread cannot exist, and nothing is sent from there.

 The first time an install reports, one line saying so is printed on the console (above the save-file menu) and a `usage-reporting-notice-shown` marker is left in the save directory so it is not printed again. The installation ID is a random UUID kept next to it, in `trace-install-id` in the save directory (`data/`, or `FISHE_SAVE_DIR`); it identifies no person, account or address, and deleting the file gives a new one. It is only created while reporting is on, so every opt-out below also stops it, and the in-browser front-end makes none. Reporting never gets in the game's way: it happens on a background thread, never raises into the game, and a server that is down or slow costs a dropped event, not a wait.

 The test suite switches reporting off for every test (`tests/conftest.py`), and the tests that exercise it point at a loopback stub server, so running the tests never reports anything either. The client is `src/trace_client.py`, vendored as one standard-library file from [trace-client-python](https://github.com/Stephenson-Software/trace-client-python) (0.4.0); the wiring is `src/usageReporting.py`.
