Welcome to Sunset Predictor. We respect your privacy and are committed to protecting your personal data. This privacy policy will inform you about how we collect, use, and protect your personal data when you visit our website and use our services, and tell you about your privacy rights and how the law protects you.

2. Data We Collect

We may collect, use, store and transfer different kinds of personal data about you:

• Alert Preferences: If you create sunset alerts, we store your alert preferences including location, quality threshold, and notification preferences.
• Push Notification Data: If you enable push notifications, we store your push notification subscription to send you alerts.
• Gallery Data: If you upload photos to the Community Gallery, we store the photos along with metadata such as location, date, and your user information. Ratings and comments on photos are also stored.
