Polymesh
Private life, shared clearly.
A quiet mesh for the people you actually share a life with — calendars, expenses, and conversation in one place.
Mission
Built for households that don’t fit a single template.
Partners, co-parents, housemates, and chosen family need coordination without turning everyday life into a public feed. Polymesh keeps your circle intimate, encrypted, and invite-led.
Inside the mesh
Your day, held in one place.
Today gathers what needs you, what’s coming up, money between people, and the shape of your household — so you start from clarity, not tabs.
Overview
What lives in a mesh.
One private tenant for your circle. Hard isolation from everyone else. Tools that stay useful when plans, money, and conversations overlap.
-
Shared calendars
See who’s free, RSVP without group-chat fog, keep personal layers private.
-
Expenses that settle
Split shared costs fairly and keep receipts where the household can find them.
-
Conversation in context
Chat that stays with the mesh so plans and decisions have a home.
-
Relationships mapped
Partner, co-parent, metamour, connected — a graph that matches real life.
-
Location, on your terms
Share live presence and places when you choose — never as a public trail.
-
Private by design
Invite-only tenancy with envelope encryption for the life you share.
Calendars
Plans without the group-chat fog.
A shared month that respects privacy. Overlay who’s free, RSVP in place, and keep personal events personal until you grant a peer a look.
- Month, week, and agenda views for the whole mesh
- RSVP and reminders without another group thread
- Personal calendars stay private until you share busy or detail
Expenses
Money between people, settled cleanly.
Log what was paid, split it across the people involved, and see balances without a spreadsheet archaeology dig.
- Fair splits by share or exact amounts
- Balances and settle flows that stay in the mesh
- Receipts kept with the expense, not lost in camera rolls
Chat
Conversation that stays with the plan.
Mesh chat keeps the thread next to the life it belongs to — mentions, reactions, and rooms for the whole circle or a quieter subgroup.
- A mesh room for everyone, plus private subgroups
- Mentions and reactions without leaving the product
- Context that doesn’t vanish into five other apps
Relationships
A graph that matches how you actually live.
Polycules, co-parenting, housemates, chosen family — Polymesh names the edges without forcing a single-couple template.
- Partner, metamour, co-parent, connected, and more
- A living map of who’s in the mesh with you
- Joint actions that respect how people are linked
Location
Presence when you choose to share it.
Live location and saved places stay inside the mesh. Share always, for a stretch, or not at all — with geofences that notify the people who need to know.
- Live share modes you control per mesh
- Places and fences for home, school, and the spots that matter
- A map for your people — not a public activity feed
Trust
Private by design, not by policy alone.
Every mesh is an invite-only tenant with hard isolation. Sensitive fields are encrypted with a per-mesh key so your calendars, expenses, and conversation stay application-layer protected.
-
Invite-led
No public discovery. People join because someone you trust invited them.
-
Hard isolation
Mesh data is scoped by tenant. Other households never share your rows.
-
Envelope encryption
Per-mesh keys wrap the life you log — not just transport TLS.
