Until a Supabase project is connected below, all data lives in this browser (localStorage) and nowhere else. Export a backup regularly either way — same discipline as NCS One.
⚠ Use PracticeOne's own Supabase project — never NCS One's. Run
supabase/01…sql, 02…sql and 03…sql in the
SQL editor first, then add each person in Auth plus a memberships row.
Upload this browser's data is the one moment local data crosses into the
firm's shared tenant — do it once, from the machine holding the real books,
after exporting a backup.
