One document, one file per attachment

  • • The document holds every task, project, area and person.
  • • It is a full snapshot each time, not a list of changes.
  • • Attached files travel beside it, one file each.

Removed before sending

  • • The path and size of your own copy of an attached file.
  • • AI keys and local model paths. Secrets are never synced.
  • • Any settings group you switched off, in both directions.

Never in the document

  • • Hidden sidebar views, and your window size and position.
  • • The passphrase. Each device keeps its key in the keychain.
  • • A lease file beside them names who may write, and holds no data.
