The app
Pacer runs on your Mac and keeps its data there. It has no account, no AI, and no telemetry, and it makes no network calls while you type.
To rank suggestions, Pacer records the commands you run, the folder you ran them in, and their exit codes in ~/Library/Application Support/pacer/data.sqlite3. For pacer stats it also records when you accept or dismiss a suggestion and how long the popover took to appear; those events are deleted after 90 days. Your settings are in settings.json in the same folder. Nothing in these files is sent anywhere.
Two commands use the network, and only when you run them. pacer update checks for a newer release and downloads it. pacer doctor asks GitHub for the latest release number. Neither sends your history, settings, or stats.
