Aphelion Engineering Pty Ltd does not collect, receive, retain on its systems, sell, or use personal data from Lunar for advertising or tracking. Lunar has no accounts, advertising, analytics, tracking, crash-reporting SDK, developer-operated server, or third-party software. Optional features can communicate directly with Apple as described below; Aphelion Engineering Pty Ltd does not receive or retain those requests or responses.
Astronomical calculations run locally on the device. If you choose to use your current location, the coordinates remain in local app storage and are available to Lunar’s own widgets and paired Apple Watch so they can calculate local events. Lunar may also send those coordinates directly to Apple’s MapKit service to retrieve a city or place name for the current location. If you enable the optional cloud-cover feature, the selected coordinates are also sent directly to Apple’s Weather service as described below. Aphelion Engineering Pty Ltd does not receive or retain these requests or responses. You can instead search for a city or use the built-in Greenwich location.
Optional cloud-cover information uses Apple Weather. When you enable it, the selected coordinates are sent directly to Apple’s Weather service under Apple’s terms. Aphelion Engineering Pty Ltd does not receive or retain that request or response. MapKit is used for current-location city naming and city search. Current-location naming may send the coordinates supplied by your device directly to Apple’s MapKit service, which returns matching place information. City search sends the text you type directly to MapKit, which returns matching places. Lunar stores the resolved or chosen place locally; Aphelion Engineering Pty Ltd does not receive it. Purchases are processed by Apple through the App Store.
Notification schedules, settings, entitlement state, and Spotlight entries are stored on your devices. If you obtain the no-charge seven-day trial through the App Store, Lunar verifies Apple’s StoreKit transaction and calculates the 168-hour access window from its signed originalPurchaseDate. Lunar stores a local offline mirror of the verified expiration and a clock high-water guard, then shares only the dated active or expired state with Lunar’s own widgets and paired Apple Watch. A best-effort ThisDeviceOnly denial guard may block reuse on the same device, but no local state can create or extend trial access; restoring the StoreKit transaction preserves its original purchase date. The trial is not a subscription, creates no charge or automatic billing, does not auto-renew, and does not contact an Aphelion Engineering server. Lunar uses local notifications only and has no push-notification server. Motion data used by the Sky view is processed on the device and is not retained.
You control these features. You can switch cloud cover off in Lunar, replace or reset the saved location, and revoke location, motion, or notification permission in Apple Settings. Uninstalling Lunar removes its locally stored settings and cached data from the device, subject to Apple’s normal device backup behavior. Local entitlement state may remain in Keychain after uninstall and may deny same-device reuse, but it cannot create or extend access. StoreKit transaction history remains required for trial and purchase access. Apple retains App Store purchase records under Apple’s terms so a transaction can be restored after reinstalling without restarting its original access window.
