# Privacy Policy for WindFlow Sandbox

**Effective date: 2026-06-27**

WindFlow Sandbox ("the app", "we", "us") is an interactive 2D aerodynamics simulation sandbox for Android. This policy explains, in plain English, how the app handles your information.

The short version: **WindFlow Sandbox collects no personal data, has no internet access, and runs entirely on your device.**

## Data we collect

**None.**

WindFlow Sandbox does not collect, store, or transmit any personal or sensitive information. Specifically, the app:

- Does **not** collect names, email addresses, phone numbers, or any account information.
- Does **not** require you to sign in or create an account.
- Does **not** include any advertising.
- Does **not** include any analytics, tracking, or telemetry.
- Does **not** request the Internet permission, and cannot send data off your device.
- Does **not** access your location, contacts, camera, microphone, photos, or files.

Everything the app does — running the simulation, computing the drag coefficient and other figures, and adjusting settings — happens locally on your device.

## Data stored on your device

The app may save your preferences and settings (such as flow and particle tuning options) locally on your device so the app behaves the way you left it. Any designs you create with planned future features would also be saved locally, on your device only.

This information never leaves your device, is never sent to us or to anyone else, and is removed if you uninstall the app or clear its data.

## Children's privacy

WindFlow Sandbox is suitable for users of all ages, including children. Because the app collects no personal data and has no internet access, it does not knowingly collect any information from children or from anyone else.

## Third-party services

The app uses no third-party services, software development kits, or networks that collect data. It works fully offline.

## Changes to this policy

We may update this privacy policy from time to time. If we make changes, we will update the effective date above. Continued use of the app after an update means you accept the revised policy.
