Privacy Policy
Last updated: August 2026
Shade Chaser ("we", "our", or "us") respects your privacy. This policy explains how we handle your information when you use our mobile application (the "App").
Information We Collect
Location Data (GPS). The App uses your device's GPS to:
- Detect your current location to find nearby bus routes
- Determine the bus direction you are traveling
- Calculate the sun position relative to your route
All location data is processed on-device only. We do not transmit, store, or share your GPS location on any server.
Motion Sensors
The App may use the device compass (motion sensor) to improve heading accuracy when GPS signal is weak. This data stays on your device.
No Account Required
The App does not require registration, login, or any personal information to function. We do not operate our own analytics or user profiling systems.
Advertising
The native iOS and Android versions of the App display banner ads throughGoogle AdMob (Google Mobile Ads SDK). AdMob may collect or use device identifiers (such as the advertising ID), IP address, and similar technical data to deliver and measure ads. This may include personalized ads based on AdMob’s default settings.
We do not sell your personal information. You can learn how Google uses data for advertising and how to control ad personalization atGoogle’s Advertising policies.
The web / PWA version of the App does not show AdMob ads.
Third-Party Services
The App displays a map using Leaflet with OpenStreetMap tiles. These services may have their own privacy policies regarding map tile requests (which may include your IP address).
Advertising is provided by Google AdMob. Google’s privacy practices are described in theGoogle Privacy Policy.
Data Storage
- Local Storage: Your language preference and saved routes are stored locally on your device using browser localStorage.
- No Cloud Storage: We do not operate any backend servers for user content. GPS and app preference data remain on your device.
Children's Privacy
The App does not knowingly collect any personal information from children.
