Households and Invites

A household is FuelKit's sharing unit. Members share the food and recipe library, the dinner plan, and the grocery list — while each person's food log, weight history, profile, targets, and API keys stay private to them. Your housemates' daily progress (calories and protein vs. their own targets) shows on your Today tab; the food behind those numbers doesn't.

Every account starts in its own solo household, so nothing is shared until you choose to invite someone.

Invite someone

In Profile → Household, the household owner can invite by email (up to 8 members total). There's no invite link to forward: the invited person simply signs in to fuelkit.app with the same Google email you invited, and an accept/decline banner appears in their app. That email match is the security — an invite can't be hijacked by whoever happens to hold a URL.

Pending invites are listed in the household view, where the inviter or owner can revoke them.

What happens on joining

The joiner must be the only member of their current household (solo). Their foods and meals merge into the new household's library; anything with the same name as an existing item is de-duplicated, and their logs re-point at the surviving copy. Nothing about their personal history changes — logs, weights, and targets come along untouched.

Leaving and removing

• Leave household (Profile → Household) moves you out into a fresh solo household. The shared library stays with the household — recipes belong to the kitchen, not the person.
• The owner can remove a member, which does the same thing on their behalf.
• If the owner leaves, ownership passes automatically to the longest-standing remaining member.

Deleting your account

Deletion is household-aware: if others remain in your household, the shared foods and meals you created are handed to a remaining member so the household's recipes keep working. See Privacy and Data Deletion.
