ZILL operates with a Local-First Philosophy. We believe your travel data belongs to you.
1. Location Data (Local Processing)
To calculate sun angles relative to your vehicle, ZILL requires access to your device's location (GPS). Crucially, this data is processed locally on your device in real-time. We do not transmit, store, or sell your location history to any external servers. The mathematical calculations happen instantly on your phone.
2. Data Collection
We do not collect personal identifiable information (PII). The app functions as a standalone utility tool.
3. Third-Party Services
The app may use standard Google Play Services for core functionality, subject to their own privacy policies.
