Astro Tracker is designed with your privacy in mind. We collect minimal data and never sell your personal information.
Location Data
If you grant permission, we access your approximate location solely to calculate when the International Space Station and Tiangong Space Station will be visible from your area. Your location is processed on-device and is never transmitted to our servers or any third party.
Notification Preferences
If you enable notifications, your device token is stored locally to deliver launch alerts. We do not operate a push notification server — all notifications are scheduled locally on your device.
Calendar Access
If you choose to add launch events to your calendar, we write directly to your device's calendar. We do not read or store any of your existing calendar data.
