Project description:
"**Android App + Backend + Admin Dashboard for App Usage Monitoring - Fixed Price Project**

We need a complete, production-ready MVP for a legal, compliant app usage monitoring system. The app will be installed on ~1000 Android phones (user consent obtained separately). It tracks app usage stats from the last 24 hours (which apps used, timestamps, total time per app, number of opens/launches) and sends data securely to a central server. An admin web dashboard displays aggregated data with filtering and basic flagging rules.

**Target launch: 4 weeks. Indian developers preferred (Bangalore/Mumbai/Pune).** Budget - Rupees 25,000/-.

## Android App Requirements (Kotlin + Modern Android)

- **Core Functionality:**
- Use `UsageStatsManager` API to query last 24h usage: per-app total foreground time, launch count (from events), first/last usage timestamps, package names.
- Data points per app: package_name, total_time_ms (24h), launch_count, first_used_timestamp, last_used_timestamp, device_id (unique per phone).
- Aggregate into daily summary (JSON) and send every 15-30 mins via HTTPS POST to backend API.

- **Permissions & UX:**
- Request `PACKAGE_USAGE_STATS` permission with deep-link to Settings > Privacy > Usage Access.
- Simple onboarding: "Enable Usage Access" button + instructions screen.
- Minimal UI: Home screen showing "Monitoring Active" status, last sync time.

- **Background Operation:**
- Foreground service (with notification) for reliable data collection even when app closed.
- Handle Android 12+ battery optimizations, doze mode, app standby.
- Local SQLite storage for offline buffering + retry logic (exponential backoff) if no internet.
- Support Android 10+ (target SDK 35).
The app should always be running in background. Even if it stopped by the user, like whatsapp, it should come back operational.

- **Security:**
- Unique device ID (generate/store securely, e.g., Firebase Instance ID).
- Encrypt data before sending (AES or HTTPS TLS 1.3).
- No root/jailbreak detection needed initially.

- **Testing:**
- Test on 5+ physical devices (various Android versions, manufacturers).
- Verify accuracy vs manual tracking (e.g., Chrome 2h 15min → exact ms).
- Edge cases: no permission, network loss, app kill, low battery.

**Deliverables:** APK (signed), Play Store-ready source code (GitHub repo), basic README.

## Backend Requirements (Node.js/Python + PostgreSQL)

- **Stack:** Node.js/FastAPI + PostgreSQL (hosted on AWS Lightsail/DigitalOcean, ~₹2k/month).
- **Database Schema:**
| Table | Key Fields |
|-------|------------|
| devices | device_id (PK), install_date, last_seen, phone_model |
| daily_usage | device_id, date (YYYY-MM-DD), package_name, total_time_ms, launch_count, first_used, last_used |
| flags | device_id, date, rule_name (e.g., "whatsapp>3h"), flagged_at |

- **APIs (REST, JWT auth):**
- POST /api/usage: Receive batched daily JSON from app (validate device_id).
- GET /api/devices: List all devices + last 24h summary.
- GET /api/device/:id/usage?date=YYYY-MM-DD: Detailed 24h breakdown.
- POST /api/flags: Manual flag + auto-rules (e.g., total_screen_time > 8h).

- **Features:**
- Auto-compute 24h aggregates on ingest.
- Data retention: 90 days.
- Basic alerting: Email/SMS if flag triggered (Twilio/SES).
- Rate limiting: 100 req/min per device.

- **Deployment:** Dockerized, auto-backup, monitoring (basic PM2 or similar).

**Deliverables:** Deployed server URL, DB credentials, API docs (Swagger/Postman).

## Admin Web Dashboard (React/Vue + Charts)

- **Pages:**
1. **Dashboard:** Overview table - all devices, last sync, total screen time (24h), top apps, # flagged.
2. **Device Detail:** Select device → 24h timeline (bar chart: time per app), launch counts, raw events.
3. **Flags:** List flagged events + rules editor (e.g., "App X > Y hours").
4. **Reports:** CSV export for date range.

- **UI Libs:** Bootstrap/Ant Design + [login to view URL] (bar/pie for time distribution).
- **Auth:** Simple email/password (Firebase Auth or JWT).
- **Responsive:** Mobile-friendly for admin phone access.

**Deliverables:** Hosted (Vercel/Netlify), source code, admin login.



## Must-Haves for Bidders
- Portfolio: Link to 1+ Android UsageStats app OR similar SaaS (backend + dashboard).
- Team: 1 Android dev + 1 fullstack (or solo with both skills).
- Experience: Android 12+ services, UsageStatsManager, PostgreSQL, React.
- Quote: Fixed total + hourly fallback if scope creep.
- NDA willingness + 1-week notice for changes." (client-provided description)
