Household Bridges™
Connect two completely independent households and share only the calendar events you choose. No shared accounts. No merged households. No shared passwords. No accidental exposure.
Everything else stays exactly where it belongs.
Why families choose a bridge
Households stay independent
No merged accounts, no shared logins, no shared household password. Two homes, two private spaces.
Only what you choose crosses
Sharing is opt-in per event. Everything you do not mark as bridge-visible simply never leaves your household.
Read-only by design
The receiving household sees a projection of the event. They cannot edit it, delete it, or reach anything else.
Disconnect any time
One tap ends the bridge and removes every shared event from the other calendar immediately.
How a Household Bridge works
Built for Real Families
Household Bridges™ solve a specific, everyday problem: the people who need part of your schedule should not need all of your household.
Co-Parents
Custody handoffs, school events, and appointments get lost in text threads.
Each parent keeps a completely separate household. A bridge shares only the events that matter to both — no shared login, no shared password, no visibility into the other home.
Blended Families
Two homes, several sets of kids, and overlapping weekends.
Bridge the households that need to coordinate, keep the rest private, and let every home run its own chores, meals, and lists independently.
Grandparents
Grandparents want to know about recitals and pickups without being on the family chat.
Share visits, school events, and holidays read-only. Grandparents never see grocery lists, chores, or household settings.
Adult Children Caring for Parents
Coordinating a parent's appointments while respecting their independence.
Your parent keeps their own household and dignity. A bridge surfaces medical appointments and visits on both calendars, and nothing else.
Caregivers
Rotating caregivers need the schedule, not the family's private life.
A caregiver bridge shows shift times, appointments, and locations — read-only, revocable in one tap, and fully logged.
Babysitters
Every sitter gets a fresh copy of the same instructions and timings.
Bridge tonight's schedule instead. The sitter sees arrival and pickup times on their own calendar without joining your household.
Tutors
Weekly sessions shift around practice, travel, and school breaks.
Share the tutoring sessions only. Changes propagate automatically, so nobody drives across town for a cancelled lesson.
Pet Sitters
Travel dates and feeding windows live in someone's inbox.
Bridge the travel window and the visit slots. When plans change, the sitter's calendar changes with them.
Emergency Contacts
The person you call in a crisis has no idea what your week looks like.
Give a trusted contact a minimal, read-only view of the household's key moments — and disconnect it the moment it is no longer needed.
Privacy is the product, not a setting
Household Bridge™ sharing was designed backwards from the worst case: what would it take for something private to leak? The answer shaped every layer below.
Zero Trust authorization
No request is trusted because of where it came from. Every bridge read and write is authorized on the server against your household membership and the current bridge state.
Server-side only bridge records
Bridge tables are not readable directly by client applications. The app asks the server, and the server answers with only what your account is entitled to see.
Read-only event projections
A shared event is projected, never copied. The receiving household holds no independent record and cannot alter the original.
No household merging
Bridging never combines two households. Members, roles, and data stay exactly where they were created.
Permission-based sharing
Only a household owner can create, accept, or disconnect a bridge, and only explicitly marked events are shared.
Full audit trail
Invitations, acceptances, declines, and disconnections are logged so the owner can review the history of every connection.

Household Bridges FAQ
- What are Household Bridges™?
- A Household Bridge is a secure, invitation-based connection between two completely independent HausPlatz households. Once connected, each household can mark individual calendar events as bridge-visible, and only those events appear on the other household's calendar.
- How is this different from a shared calendar?
- A shared calendar usually shares an entire calendar with everyone who has access. A bridge shares individual events you choose, in one direction at a time, read-only, between two households that otherwise remain completely separate.
- Can my ex see my grocery list?
- No. Groceries, meals, chores, to-do lists, members, documents, household passwords, and settings never cross a bridge. Only events explicitly marked as bridge-visible are shared.
- Can grandparents use Household Bridges?
- Yes. Grandparents create their own free household and accept a bridge invitation. They see the events you share on their own calendar and nothing else from your home.
- Can I disconnect a bridge?
- Yes, at any time and without asking the other household. Disconnecting immediately removes every shared event from the other household's calendar and records the action in your audit trail.
- Who owns a shared event?
- The household that created the event always owns it. The receiving household holds a read-only projection — they cannot edit, delete, or duplicate it into their own data.
- Can multiple households connect to mine?
- Yes. A household can maintain several bridges at once — for example a co-parent, a grandparent, and a caregiver — and each bridge is controlled and shared separately.
- How secure is a Household Bridge?
- Every bridge action is authorized server-side. Bridge records are not directly readable by client applications; the projection of shared events is assembled by the server after verifying membership and bridge status on each request.
- Can caregivers use Household Bridges?
- Yes. Caregiver, babysitter, tutor, pet sitter, and emergency-contact bridges are all supported, each with the same read-only, event-only sharing model.
- What happens if I delete a shared event?
- It disappears from both calendars. The same is true if you simply change its visibility back to household-only — the shared copy is removed instantly because there is no separate copy to clean up.
- How does privacy actually work?
- Households are never merged. Authorization is evaluated on the server for every read, sharing is opt-in per event, projections are read-only, and every bridge lifecycle action is written to an audit trail.
- Do both households need HausPlatz accounts?
- Yes. Each side keeps its own account and its own household, which is exactly what keeps the two spaces independent. Creating a household is free during the public beta.
- Can I choose which events to share?
- Yes — event by event. When you create or edit an event in HausPlan™ you choose its visibility, and only the bridge-visible ones are shared.
- Can children edit bridged events?
- No. Bridged events are read-only for the entire receiving household regardless of role, and roles such as child, teen, and guest have additional restrictions inside their own household.
- What details of an event are shared?
- Title, date and time, all-day status, category, and location. Descriptions, attendees, attachments, links, and recurrence internals are not exposed across a bridge.
- Does a bridge sync both directions?
- Each household independently chooses what to share. If both sides mark events as bridge-visible, both sides see each other's shared events — but neither side can share on the other's behalf.
- Is there an audit trail?
- Yes. Bridge invitations, acceptances, declines, and disconnections are recorded so the household owner can review exactly what happened and when.
- Does a Household Bridge cost anything?
- No. Household Bridges are included at no extra cost for eligible households during the HausPlatz public beta.
