Two-device household, one shared log
A couple near Namyangju-si joined Ledger Circle after realizing each person kept partial notes on different phones. They adopted the course’s “access steward of the day” tag and a paper master sheet for weekend reviews.
Outcome they reported: fewer duplicate unlocks for routine balance checks, and a clearer trail when a visiting relative needed temporary observation-only access. They did not change any investment strategy — only how openings were recorded.
