Last updated: January 2026

This Privacy Policy describes how 4K Live Wallpapers Auto Changer 2026 ("we", "the app") handles information when you use our Android application.

1. Information We Collect

We do not collect, transmit, or share any personally identifiable information (such as name, email, or device IDs) with our servers or third parties. The app works offline for already-downloaded content and only fetches public wallpaper catalog and media files when connected to the internet.

2. Permissions and Why We Use Them

• INTERNET — To load the wallpaper catalog (JSON) and images/videos from our content servers.
• ACCESS_NETWORK_STATE — To check network availability and fall back to cached data when offline.
• SET_WALLPAPER — To set static or live wallpapers on the home screen and/or lock screen as you choose.
• READ_EXTERNAL_STORAGE / WRITE_EXTERNAL_STORAGE — To cache wallpaper catalog (JSON), images, and videos on your device for faster loading and offline use. We do not read your personal files (e.g. photos, documents).

3. Data Stored on Your Device

We store the following only on your device:

• Wallpaper catalog cache — A copy of the wallpaper list (IDs, URLs, categories) to support offline browsing.
• Image and video cache — Cached wallpaper images and videos you have viewed or set, to improve performance and allow offline use.
• Video wallpaper settings — Your choices for video wallpaper (e.g. play mode, interval) are saved locally via Android SharedPreferences. They are not sent to any server.

You can clear this data via Android Settings → Apps → 4K Live Wallpapers Auto Changer 2026 → Storage → Clear cache / Clear data.

4. Third-Party Services

The app uses:

• OkHttp — For network requests (loading catalog and media). We only request our own content URLs.
• Glide — For image loading and caching. It does not collect or share your data.
• VideoCache (e.g. HttpProxyCacheServer) — For streaming and caching videos. Cached data stays on your device.

We do not use analytics, advertising SDKs, or social login. We do not sell or share your data with advertisers or data brokers.

5. Children's Privacy

Our app does not target children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it.

6. Changes to This Policy

We may update this Privacy Policy from time to time. We will post the updated version (with a new "Last updated" date) in the app or on the app's store listing. Continued use of the app after changes means you accept the updated policy.

7. Contact

If you have questions about this Privacy Policy or the app's practices, please contact us at the email or address provided in the app's store listing or in the app's "About" or "Settings" section.
