HP Factory

A private automation tool with a single user. It runs software-delivery tasks on its owner's own computer and files a note into that owner's mailbox when a human decision is needed.

It is authorised to read mail, manage labels, and insert a message into its owner's own mailbox. It cannot send email — the permission that would allow that is deliberately not requested.

It is not a product, has no other users, and has no sign-up.
