Stack AR for iPhone and iPad · Last updated 12 September 2026

Stack AR does not collect, store, transmit, or share any personal data. There are no accounts, no analytics, and no network connections of any kind.

What the app does not collect

The app has no sign-in, no user profiles, and no server component. It does not gather your name, email address, device identifiers, location, contacts, usage analytics, or crash reports. It contains no advertising and no third-party SDKs. Every framework it uses is supplied by Apple as part of iOS.

What the app accesses, and why

Camera. Stack AR requires access to your device's camera. This is what makes augmented reality possible: the camera image is what the tower is drawn on top of, and it is also how the app finds the floor or table you place the tower on.

• Camera frames are processed entirely on your device by Apple's ARKit framework.
• No photo, video, or camera frame is recorded, saved to your photo library, or written to storage by the app.
• Nothing from the camera is transmitted anywhere. The app cannot send it, because it makes no network requests at all.
• People in view are separated from the background on device so they can be drawn in front of the tower. That separation happens frame by frame and nothing about it is kept.
• You can refuse or revoke camera access at any time in Settings. The app cannot draw without a camera feed, but it will say so rather than fail silently.

Motion sensors. ARKit uses the device's accelerometer and gyroscope to track how you move around the room so the tower stays where you put it. This data is used only for live tracking, is handled on device, and is never stored or transmitted.

The app also plays sound and haptic feedback as blocks land. Neither requires a permission and neither reveals anything about you.

What is stored on your device

The app saves one thing in its own storage on your device: your high score. It is never sent anywhere, because the app makes no network connections at all, and the developer has no access to it. Deleting the app removes it.

Children

Stack AR is rated 4+ and is suitable for all ages. Because it collects no data whatsoever, it collects no data from children either.

Third parties

There are no third-party services, analytics providers, advertising networks, or data processors involved in this app. No data is sold or shared, because none is collected.

Changes to this policy

If a future version of the app changes what it accesses, this policy will be updated before that version is released, and the date at the top of this page will change.
