Science Voyager Privacy Policy
Updated September 22, 2026 · Developer: huag
This policy applies to Science Voyager (com.huagx.voyager), an offline science exploration app that does not require an account.
Information on your device
The app stores the identifiers of experiments you have opened on your device to display exploration markers and progress. Searches, experiment interactions and progress are not uploaded to a developer server or synchronized between devices. The system and embedded runtime keep operational caches and settings locally.
Collection and permissions
The app has no advertising, behavioral analytics or third-party crash reporting service. It does not collect or transmit personal information to the developer or track users across apps. Core features do not need camera, microphone, contacts, location or personal document access. Experiment resources are included with the app and work offline.
Free experiments and purchases
Earth Rotation, Lever, and Prism are always free to explore. A single non-consumable in-app purchase permanently unlocks the other 47 experiments, with no subscription or automatic renewal. The price is displayed by the App Store.
Apple handles purchases, payment, and restoration, which require an internet connection. StoreKit verifies purchase entitlements on your device; purchase records and payment details are not sent to a developer server. Experiment resources are bundled; unlocked experiments work offline with valid local StoreKit entitlements. After reinstalling or changing devices, select Restore Purchases in the unlock screen with the original Apple Account.
Children
The app does not ask children for names, contact details or other personal information. A parent or teacher should help explain the scientific models and their simplifying assumptions. Support requests should be sent by an adult without including a child's personal information.
Support correspondence
If you contact huag9998@gmail.com, your email address and the information you send are used to answer and address the request. Do not include passwords or sensitive information. Messages are processed by the sender's and recipient's email services.
Local data and updates
Exploration records are stored locally and cannot be restored from a server. Contact support for help removing local records or questions about information handling. This policy will be updated when the app's practices change.
