Reference

Touch and pointer interactions, how data is stored, and what's in the side panel — quick lookups, not a tutorial.
This is the summer 2026 guide.
Some of it has changed since. A new guide (v1) is being written.

Reference

Touch and pointer interactions

On the tree canvas:

  • Hover / tap a person chip — reveals 💬. Tap to open their direct chat.
  • Hover / tap a family card — reveals 💬. Tap to open the family group chat.
  • Double-click / double-tap a person chip — navigates to their origin family (parents).
  • Ctrl+double-click (desktop) or long-press (touch) — navigates to their own family (children and spouse).

Data persistence

Tree data is stored in a local SQLite database. Changes are saved automatically after every action.

Export is still useful for:

  • Off-device backup
  • Sending your tree to someone without relay access
  • Version control (tree.yaml in a backed-up folder)
  • Rebuilding on a fresh install
tree export --format yaml

Paste the output somewhere safe. To restore, paste it directly into the terminal — multi-line paste is auto-detected.

The side panel

Person view

Details — Full name, birth/death dates, gender, and family memberships (child in, parent in). A 🔗 button generates a personal invitation for that slot. Key moments and any assigned articles appear here too — see Family history and the atlas.

Chat — A private direct message thread. Encrypted over the family cell. The person must have joined via invitation to receive messages.

Family view

Members — All parents and children. A green dot marks members who have connected. 🔗 next to each row generates a personal invitation for that person.

Chat — Group chat private to all members who have joined. The relay cannot read it.

Invite — Quick link for a family-level invitation (not tied to a specific person record).
