Consent-first trip logging for NATPAC
Capture trip chains with origin, mode, destination and companions— passively detected, user-verified, and synced for planners across भारत

The problem
Manual household travel surveys are slow, costly, and cover a tiny share of the population. NATPAC needs accurate, continuous trip data—trip number, origin, time, mode, destination— to establish activity chains and plan better.
How it works
Consent-first, offline-friendly logging—from detection to verified trip chains.
Splash & Sign up
Email sign-up with OTP verification, or continue as guest. DigiLocker planned.
Detect or Start Trip
Auto-detect movement beyond ~200m and nudge. Or start a trip manually.
Confirm Details
Add companions, select mode, set start/end on map, then proceed.
Sync & Analyze
Data is stored locally during trip, synced when online for planners.
Consent & privacy
We ask for explicit consent and explain why background location and battery optimizations are required. Data stays local during trips and syncs only after completion (or when back online).
Explicit consent
Transparent permissions and opt-outs, including privacy pauses.
Battery-optimized
Designed to work efficiently in background with user awareness.
Offline-first
Data is stored locally and synced when online.
Built for travel data collection
Accurate, privacy-aware trip logs for planning and research.
Passive Trip Detection
Detect trips when movement exceeds ~200m and nudge users to confirm.
Smart Mode Estimation
Infer walk vs vehicle from speed, distance and timestamps.
Companions & Metadata
Capture companions, origin/destination, purpose, and mode in one flow.
Trip history
Neat maps, distances, duration, modes, and companions per trip.
Trip chains
Visualize trip segments and transitions across modes.
Detailed stats
Distance, duration, pace, and inferred mode confidence.
Future scope
Planned enhancements for engagement and safety.
Privacy pauses
Stop tracking in sensitive places or during private trips.
Safety gestures
Shake phone to alert companions with location.
Streaks & sharing
Maintain travel streaks, share highlights on social media.
Leaderboards
Weekly leaderboards for friendly competition.
Admin dashboards
Role-based access (super admin, admin) for aggregated, privacy-preserving analytics.
City-wide trends
OD matrices, mode shares, peak hours.
Data governance
Consent logs, anonymization, retention policies.
Role management
Super admin and admin roles with audit trails.
