1. One Spreadsheet as Database
Your spreadsheet is the database. The app writes only what changed, never clobbers human updates, preserves existing cell comments and formatting, and never deletes without explicit confirmation.
One permissioned Google Sheet is the single source of truth. The family curates it by hand. The dashboard ingests your Sheet and shared family calendar, generates the Sunday agenda, tracks school holidays, schedules date nights, coordinates home maintenance, and manages household finances.
