Tools
Do the next useful thing
Standalone tools. Use them without an account. Each one says what you leave with: a calendar file, a letter, a printable log, or a draft plan. Harbor is optional if you later want a shared calendar or ledger.
Schedule
Build a rotation and take it home as a calendar file.
Money
Split one cost or estimate guideline support.
Records
A log you can print. Facts only.
Plans
A draft you can walk through before anyone files.
Check-in
Two-at-a-time votes. No names, not a court exhibit.
