An install is a random install ID. By agents: the share of launches an AI agent ran. Days are UTC. Updated hourly, last at Oct 29, 22:16 UTC.

Sent

app_installed
The first time an install sends anything.
app_started
Each time the product starts.
feature_used
A feature runs: a command such as chats list or an action such as redact. Names come from a fixed list in the product; anything else is sent as other.
error_occurred
A command or action fails. It carries the error’s type and message, with your home folder and user name taken out.

With each event

The product and its version, the operating system and its version, the CPU architecture and runtime, how the product was installed, how it runs (in a terminal, under an AI agent, from a script, on a schedule), which agent runs it, and the random install ID. Scripts, scheduled jobs, daemons and plugins send each event at most once a day.

Never sent

  • Files, documents and messages
  • Command arguments; file names and paths, except in an error
  • Host names, user names and environment values
  • Account names, chat and user IDs
  • Licence keys and hardware IDs

Turn it off

DO_NOT_TRACK=1 turns it off in every product. Each one also has its own switch:

Nothing is sent before a product has shown you its notice, or from CI and test runs. Turning it off deletes the install ID. Put status in place of off to see whether it’s on and your install ID.

Where it goes

Events pass through this site on Vercel to PostHog (PostHog, Inc.), which stores them in its US Cloud as my processor. PostHog receives your IP address, derives your country from it and keeps the address with the event.

Deletion

Events are kept in PostHog. To have yours deleted, write to sergey@goodit.works with your install ID.
