Privacy Policy

Last updated: September 2026

      100% ON-DEVICE PRIVACY PROMISE:
      Traffic Zen processes all camera video frames, speed calculations, and computer vision models entirely on your iPhone using Apple Neural Engine. Your camera video is never recorded, never stored on disk, and never transmitted over the internet.
    

1. Information We Do Not Collect

We believe your drive is private. Traffic Zen does not:

Upload or transmit camera frames or video streams to any cloud server.
Record audio or eavesdrop on conversations.
Track, store, or sell your precise location history or driving routes.
Collect personally identifiable information (PII) without your explicit consent.

2. Camera Access

Camera access is required solely for the real-time detection of traffic lights while the app is active and foregrounded. Camera buffers exist in volatile device memory (RAM) only during inference and are discarded immediately after frame processing.

3. Location Services

Location access (GPS) is used locally on your device to estimate vehicle speed. Speed is used strictly to gate alerts (suppressing pings while moving at highway speeds). Your coordinates and GPS tracks are never saved or sent to any remote server.

4. Anonymous Diagnostics & Analytics

On our marketing website, anonymous web visits and traffic referral sources may be analyzed using privacy-respecting analytics (such as Cloudflare Web Analytics or Google Analytics 4) to understand referral sources. No personal profiling or third-party advertising tracking is performed.
