Ringleader

A private tool its owner built to manage his own online stores and advertising accounts. It reads performance data from the accounts he owns, keeps a record of every change made to them, and drafts routine work for his review.

It has a single user, its owner. There is no sign-up, no public product, and no service offered to anyone else.

Google account access

Ringleader connects to Google Ads, Google Analytics and Google Search Console using a Google Cloud service account under the owner's control, granted access from inside those products the same way a colleague would be. It authenticates as itself, not on behalf of any visitor, so there is no sign-in flow here that touches your Google account.
