BlackHole is a real-time relativistic black-hole simulator for Android, iOS, macOS, and visionOS, published by Orch Aerospace, Inc. (“we”, “us”). This policy explains what data the BlackHole app does and does not handle.
None. BlackHole does not collect, transmit, store on our servers, or share any personal data, usage data, identifiers, location, or contact information. We do not run analytics, advertising, or crash-reporting SDKs, and we do not embed Firebase, Google Analytics, Sentry, Mixpanel, Amplitude, Segment, PostHog, or any other third-party telemetry.
The Android app performs all physics and rendering on your device. It does
not request the INTERNET permission and makes no network requests
of its own — it runs entirely offline.
These never leave your device and are not visible to us:
SharedPreferences so the app reopens to your last configuration.You can erase all locally stored settings by clearing the app's storage or uninstalling the app.
The Android app requests no runtime permissions. It declares only a hardware feature requirement (a Vulkan-capable GPU) so the Play Store can filter incompatible devices.
The Android edition of BlackHole has no subscriptions or in-app purchases. (On other platforms, purchase and entitlement data is handled entirely by the operating system's first-party store framework; we receive only an opaque “unlocked: yes/no” bit and never see your name, payment method, or store account.)
BlackHole is not directed at children under 13, and we do not knowingly collect data from anyone, of any age.
If this policy changes, we will update the “Last updated” date above and post the revised version at this URL.
