People

A person is Rupt's best estimate of a single human behind an account. Most accounts are one person, so the usual picture is one person per account. When Rupt sees more than one, the account is being shared.

That's the whole point of the concept. People is how you see, at a glance, whether an account belongs to one human or several. It exists for account sharing and nothing else.

How Rupt works it out

People come entirely from device signals. When the devices on an account look like they can't all belong to the same human, Rupt treats them as separate people and counts them.

So people don't map one-to-one to your accounts. A single account in your system can resolve to several people when several humans are clearly using it. That gap between one account and many people is exactly what sharing looks like.

What it isn't

People has nothing to do with the identity you send Rupt. The user ID, email, phone, and metadata you pass during an evaluation identify the account. People runs the other direction: it's Rupt's read on how many humans are actually behind that account, inferred from devices, never from anything you told it.

All-time vs active

You'll see two figures on an account:

• All-time people: every distinct person Rupt has ever seen on the account.
• Active people: the ones using it right now.

A jump in either is the tell that an account has gone from one user to a shared one.
