Do family members share my receipts and budgets?

You choose. Set up a shared household budget everyone can add to and see, and keep your own private budgets alongside it. When you enter a receipt you pick which budget it goes to, so a shared grocery run lands in the household budget while a personal buy stays in yours. Private budgets are visible only to you; receipts you add to a shared budget are visible to everyone in the household. The plan and the monthly credit pool are always shared.
