Stellar Finder ("the App") is designed to identify celestial objects using your device's camera and sensors. This privacy policy explains what data the App accesses and how it is used.
What we collect: The App captures images from your device's camera to perform plate solving (star field identification).
How we use it: Camera images are processed locally on your device to identify stars and celestial coordinates. Images are only saved if you explicitly choose to export them.
Storage: All camera data is processed and stored locally on your device. No images are transmitted to external servers.
What we collect: The App accesses your device's GPS location when you use location-based features.
How we use it: Location data is used to improve plate solving accuracy by providing initial pointing estimates. This helps the solver identify your star field faster.
Storage: Location data is processed locally and not transmitted to any external servers or third parties.
What we collect: The App accesses your device's orientation sensors (accelerometer, magnetometer, gyroscope).
How we use it: Sensor data helps estimate where your camera is pointing in the sky, improving plate solving speed and accuracy.
Storage: Sensor data is processed in real-time and not stored permanently.
The App does not share, transmit, or upload any of your data to external servers or third parties. All processing happens locally on your device.
The App stores the following data locally on your device:
You can delete all app data by uninstalling the App or clearing the App's data in your device settings.
The App does not use any third-party analytics, advertising, or tracking services. The App operates entirely offline after installation.
The App does not knowingly collect personal information from children. The App is designed for educational and amateur astronomy purposes and can be used by users of all ages under appropriate supervision.
We may update this privacy policy from time to time. Any changes will be posted on this page with an updated "Last Updated" date.
