+# Requirements: HouseHoldKeaper
+
+**Defined:** 2026-03-15
+**Core Value:** Users can see what needs doing today, mark it done, and trust the app to schedule the next occurrence — without thinking about it.
+

+

+- [ ] **TASK-06**: User can sort tasks within a room by due date (default sort order)
+- [ ] **TASK-07**: User can mark a task as done via tap or swipe, which records a completion timestamp and auto-calculates the next due date based on the interval
+- [ ] **TASK-08**: Overdue tasks are visually highlighted with distinct color/badge on room cards and in task lists
+
+### Task Templates
+
+- [ ] **TMPL-01**: When creating a room, user can select from bundled German-language task templates appropriate for that room type

+- [ ] **PLAN-04**: User can swipe-to-complete or tap checkbox to mark tasks done directly from the daily plan view
+- [ ] **PLAN-05**: User sees a progress indicator showing completed vs total tasks for today (e.g. "5 of 12 tasks done")
+- [ ] **PLAN-06**: When no tasks are due, user sees an encouraging "all clear" empty state
+
+### Cleanliness Indicator
+
+- [ ] **CLEAN-01**: Each room card displays a cleanliness indicator derived from the ratio of overdue tasks to total tasks in that room
+
+### Notifications
+
+- [ ] **NOTF-01**: User receives a daily summary notification showing today's task count at a configurable time

+- [ ] **THEME-02**: App uses a calm Material 3 palette with muted greens, warm grays, and gentle blues
+
+### Foundation
+
+- [ ] **FOUND-01**: App uses Drift for local SQLite storage with proper schema migration workflow
+- [ ] **FOUND-02**: App uses Riverpod 3 for state management with code generation
+- [ ] **FOUND-03**: App uses localization infrastructure (ARB files + AppLocalizations) with German locale, even though only one language ships in v1

+
+## Out of Scope
+
+Explicitly excluded. Documented to prevent scope creep.
+
+| Feature | Reason |
+|---------|--------|
+| User accounts & cloud sync | Local-only by design — zero backend, zero data leaves device |
+| Leaderboards & points ranking | Anti-feature — gamification causes app burnout and embeds unequal labor dynamics |
+| Subscription model / in-app purchases | Free forever by design — paywalls are the #2 complaint in chore app reviews |
+| Family profile sharing across devices | Single-device app; cross-device requires cloud infrastructure |
+| AI-powered task suggestions | Requires network/ML; overkill for personal app with curated templates |
+| Per-task push notifications | Causes notification fatigue; daily summary is more effective for habit formation |
+| Focus timer / Pomodoro | Not a productivity timer app; out of domain |
+| Firebase or any Google cloud services | Contradicts local-first, privacy-first design |
+
+## Traceability
+
+Which phases cover which requirements. Updated during roadmap creation.
