Privacy Policy

1. Introduction

GrandAuto Studio ("we", "us") built Game Booster X Premium ("the app"). This page explains how the app handles information when you use it. We believe in privacy by design: the app runs entirely on your device and does not collect, store, or transmit any personal data.

2. Information We Collect

The app does not collect, transmit, or store any personal data. There are no accounts, no analytics SDKs, and no advertising identifiers. Everything happens on your device.

3. Device Data Used Locally

To provide its features, the app reads the following information locally. None of it ever leaves your device:

• Device performance telemetry — CPU usage, memory, storage, battery level and temperature, uptime, and network throughput — used by the monitoring tools.
• Installed applications — used only to detect games for the Game Library and to launch games you choose.
• Your play sessions, favorites, benchmark history, and settings — stored in the app's own on-device Room database and DataStore.
• Media file metadata (names and sizes) — used only by the Storage Analyzer to show you large files, APKs, downloads, and duplicates. The app never uploads these files.

4. Permissions and Why They Are Used

• INTERNET / ACCESS_NETWORK_STATE / ACCESS_WIFI_STATE — network tools and connectivity labels.
• POST_NOTIFICATIONS — boost results and dashboard notifications.
• CAMERA / FLASHLIGHT — optional flashlight toggle in the Gaming Dashboard; no images are captured.
• FOREGROUND_SERVICE + FOREGROUND_SERVICE_MEDIA_PROJECTION — in-app screen recording and screenshots; recordings are saved only to your device and only when you start them.
• ACCESS_NOTIFICATION_POLICY — Do Not Disturb toggle that you trigger manually.
• READ_MEDIA_IMAGES / READ_MEDIA_VIDEO / READ_MEDIA_AUDIO / READ_EXTERNAL_STORAGE (Android 12 and below) — Storage Analyzer only; cleanup only touches files owned by the app.

5. Data Security

No network accounts, analytics SDKs, advertising IDs, or third-party trackers are used. Because nothing is collected, there is nothing to secure off-device. Sensitive values, when present, are encrypted using the Android Keystore.

6. Data Storage and Deletion

All data is stored on your device. Clearing the app's data or uninstalling the app permanently deletes it. The app does not have servers to store anything on.

7. Children's Privacy

The app is not directed to children under 13 and does not knowingly collect any information from children.

8. Changes to This Policy

We may update this policy from time to time. Any changes will be posted on this page with a new effective date. Continued use of the app after changes means you accept the updated policy.
