A wallet can be shared with other people — a household budget, money managed with a partner, a pot two people both put into.

Each member holds a role. Owner controls the wallet and who is in it. Editor can record and change money. Viewer can see everything and change nothing.

People join by invitation, sent to an email address or as a link, and an invitation expires rather than standing open forever. It can also be revoked before it is accepted.

Sharing is per wallet, which is the point of having more than one: the household wallet can be shared while everything in your personal wallet stays yours alone.
