Setting up a household
One lunarlog account can look after several people's cycle logs, and each profile can be shared with the people who help care for it. This guide covers the pieces; the inviting guide covers the handshakes.
One profile per person
Each profile holds one person's cycle log. After signing in, you can invite another guardian — a co-parent or caregiver — to view or help log it. Profiles never mix: Sam's log and her daughter Maya's log are two profiles, with separate histories, estimates, and guardian lists, even when both live on the same phone.
Add another profile any time from the profile picker — Profiles, reached with Switch profile from the overview — and Add profile walks the same short setup as the first one. Switching profiles is one tap, and a profile you are invited into later appears in the picker under Shared with me, with your role next to it.
When a profile is for a child or teenager, the This profile is for a minor flag marks it. It is a label the household controls, and it matters for framing — teen-appropriate wording, and estimates that hedge accordingly — rather than for storage. A minor's profile is never shared beyond its guardians, and when the child is old enough, ownership can move to her own account, with every past entry intact.
The four guardian roles
Everyone with access to a profile is a guardian, and every guardian has exactly one role on that profile. The app's own summary of what each role allows:
What the guardian roles allow
Four roles, from most to least access: primary guardian, co-parent, caregiver, viewer.
The primary guardian owns the profile: they can edit it, manage guardians, and delete it. There is exactly one per profile. A co-parent can log entries, edit the profile, and manage guardians, but cannot delete the profile.
A caregiver can log entries on the profile but cannot change the profile itself or manage guardians. A viewer can only read — the day sheet is read-only for them.
Every entry keeps who logged it, so shared logging stays attributed no matter the mix of roles.

In short, from most to fewest permissions:
- Primary Guardian — owns the profile. Exactly one per profile: edits it, manages guardians, and is the only role that can delete it or hand it over.
- Co-Parent — logs entries, edits the profile, and manages guardians, but cannot delete the profile or take ownership.
- Caregiver — logs entries, but cannot change the profile itself or manage guardians.
- Viewer — read-only; the day sheet opens read-only for them.
Reading is not rationed: every accepted guardian on a profile can read what is logged on it — roles decide who can write and manage, not a sliding scale of visibility. The one deliberate exception is a note the profile's subject marked private, which stays hers.
Each entry keeps who logged it, so shared logging stays attributed no matter the mix of roles. The role definitions live in the app too: the guardian management screen's About roles explainer shows the same ladder on any profile.
Households come in more than one shape
The setup above serves an adult tracking for herself, two parents keeping a teenager's log side by side, a caregiver helping someone through treatment — any mix. What the shapes have in common is the direction of trust: a profile's guardians are exactly the people listed on it, no one else ever receives its data, and every addition is an explicit invitation someone accepted.
