Privacy Policy — Sphere Packing Helper

Developer: VP GAMESS
Contact: lyidmilazuelinska@gmail.com
Effective date: 30 September 2025

1) Overview

Sphere Packing Helper is a simple calculator that estimates how many equal-size spheres fit inside a rectangular box. The app works entirely on-device. It does not create user accounts and does not send personal data to any server.

2) Data we collect

We do not collect, store, or share personal information. Calculation inputs (box dimensions, sphere diameter, and the selected packing coefficient) remain on your device and are used only to show the result. Items shown in the History screen are stored locally and are removed if you uninstall the app.

3) App permissions

The app does not request runtime permissions such as access to contacts, location, camera, microphone, or storage.

4) WebView usage

The app includes a WebView component only to display this privacy policy so the text renders consistently across devices. The WebView does not load third-party content, does not inject trackers, and does not require cookies. Any logging performed by your device, operating system, or network provider is outside our control.

5) Third parties and analytics

We do not use third-party analytics, advertising SDKs, crash reporters, or an advertising identifier (IDFA/AAID). No data is shared with marketing or profiling services.

6) Children

The app may be used by students with guidance. Because the app collects no personal data, it is suitable for general audiences. If you believe a child has provided personal information to us, please contact us; our design intentionally avoids collecting such information.

7) Security

The app processes data locally to minimize exposure. As with all software, please keep your device and the app updated.

8) Changes to this policy

We may update this policy to reflect app or legal changes. Updates will appear on the in-app policy page. Continued use after an update constitutes acceptance of the revised policy.
