Privacy Policy

Information We Collect

Marble Detector is designed to minimize data collection. The app does not require you to create an account and does not ask for personally identifiable information such as your name, email address, or phone number.

• The app may process sensor data on your device (for example, motion or touch input) to power the interactive marble experience. This data is handled locally on your device and is not stored or transmitted to our servers.
• The App Store itself may collect anonymized analytics or crash data if you have opted in at the system level. That data is managed by Apple under their policies, not by Marble Detector.

How We Use Data

Any data processed by Marble Detector is used solely to provide the core app functionality—for example, responding to your device's movement, touch, and input to animate marbles and physics effects.

We do not sell your data, and we do not use it for targeted advertising.

Third‑Party Services

Marble Detector may rely on services provided by Apple (such as iCloud, app updates, or App Store infrastructure). These services are governed by Apple's own privacy policy .

Children's Privacy

Marble Detector is designed to be broadly accessible, but it does not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us so we can review and, if appropriate, delete the information.

Data Retention

Because Marble Detector does not create accounts or collect personal identifying information directly, there is no persistent profile stored on our servers. Any settings you adjust within the app are stored locally on your device and are removed if you delete the app.

Your Choices

You can control system‑level analytics and crash reporting through your device settings under Apple privacy options. You can also remove all app data at any time by deleting Marble Detector from your device.

If you have any questions about this Privacy Policy or how Marble Detector handles data, you can reach us using the details on the Contact page.

Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes to the app or to applicable laws. When we do, we will update the "Last updated" date below. Your continued use of Marble Detector after any changes indicates your acceptance of the updated policy.
