Privacy Policy
How we handle your information
Last updated: May 2026
1. Overview
This Privacy Policy explains how Nexora AppLabs ("we", "our") handles information when you use HD Wallpaper.
We designed the App so most wallpaper browsing works offline. We collect minimal data and store preferences locally on your device.
2. Information Stored on Your Device
- Favorite wallpapers — saved locally using SharedPreferences.
- Dark mode preference — saved locally on your device.
- Notification rotation index — saved locally to show different reminder messages.
- Swipe hint status — saved locally so onboarding hints are shown only once.
- Pending lock wallpaper path — saved locally when needed on some devices after restart.
This data stays on your phone and is not uploaded to our servers.
3. Permissions
- Storage / Photos — used to set wallpapers on Android when required by the device.
- Notifications — used for optional daily reminders at 8:00 AM and 8:00 PM.
- Internet — used for ads, Firebase Remote Config, and opening external links such as the Play Store or Amazon Appstore.
You can deny permissions, but some features may not work fully.
4. Advertisements (Google AdMob)
The App uses Google AdMob to show banner, interstitial, and app-open ads.
Google may collect device identifiers, ad interaction data, and similar technical information to serve and measure ads.

5. Firebase Remote Config
We use Firebase Remote Config to manage app settings such as ad toggles, interstitial frequency, force-update build number, and store URL.
Firebase may process technical device and app instance data needed to deliver configuration values.
If the device is offline, the App uses safe local default values.
6. Local Notifications
The App schedules local notifications on your device for wallpaper reminders.
These notifications are generated on-device and do not require uploading your personal information to our servers.
You can disable notifications from Android system settings at any time.
7. Analytics & Crash Data
Firebase Analytics may be included through the Firebase SDK to understand general app usage.
We do not ask for your name, email, phone number, or address inside the App.
8. Children's Privacy
The App is not directed at children under 13. We do not knowingly collect personal information from children.
9. Data Security
Local app data is protected by your device operating system.
No method of storage or transmission is 100% secure, but we take reasonable steps within the App design to minimize data collection.
10. Your Choices
- Turn off notifications in Android settings.
- Clear app data to remove favorites and local preferences.
- Uninstall the App to stop all local processing by the application.
11. Changes to This Policy
We may update this Privacy Policy from time to time. The "Last updated" date at the top will change when revisions are made.
