# Federations

The Federation owns your data and pays for Hubble

A Federation is the top level of Hubble. It owns all of the data in its [Universes](/fundamentals/universes.md). It also holds the license that pays for Hubble.

Usually, a Federation is a campaign committee, a political club, a party or an agency.

## Create a Federation

When you sign up for Hubble, Hubble asks you to create a Federation and its first Universe. You can create more Federations at a later time.

If your campaign already uses Hubble, do not create a new Federation. Ask a manager of your campaign to invite you.

## One Universe or many

Most campaigns and clubs keep all of their data in one Universe.

Some Federations must keep data apart, for example a party or an agency with many campaigns. These Federations can create more Universes. Each Universe keeps its own data.

To share contacts between the Universes of a Federation, create a [Multiverse](/fundamentals/multiverses.md).

## Members

A Federation member has access to every Universe in the Federation. The member has the same role in each Universe.

People who work in only one Universe, such as volunteers and staff, do not have to be Federation members. Add them to that Universe instead. Most volunteers never see the Federation.

The role of a member also controls what the member can do in the Federation Hub:

| Role                | The member can                                                                                                                      |
| ------------------- | ----------------------------------------------------------------------------------------------------------------------------------- |
| Owner               | Do all tasks. Each Federation has one Owner.                                                                                        |
| Manager or higher   | Invite members and remove members.                                                                                                  |
| Treasurer or higher | Manage the subscription, the payment card and the invoices, and cancel the subscription. These members also get the billing emails. |

## Billing

The license of the Federation sets which hubs its Universes can use. To change the plan, the card or the subscription, open the **Billing** tab in the Federation Hub.
