2. Information we collect
We do not require you to create an account to use the App. We do not intentionally collect sensitive personal information such as government IDs or payment card details. However, the App and the third-party services integrated into the App may collect the following categories of information.

When you use the App, we and our third-party SDK partners may automatically collect:
- Device type, model, manufacturer and operating system version
- Language and region settings

- Network type (Wi-Fi, mobile data) and mobile carrier/ISP name (non-identifying)
-
Device or other IDs, which may include:
- Google Advertising ID (GAID / AD_ID)

- App-specific identifiers
- IP address, which may be used to derive approximate location (e.g. country or city level, not precise GPS)
Purposes of use:
- To deliver and display ads, including personalised ads where permitted
- To perform analytics and understand how the App is used
- To limit how often you see the same ad (frequency capping)

These Device or other IDs, IP address and related technical information may be shared with third-party advertising and analytics providers such as Google AdMob, AppLovin, Meta Audience Network, Unity Ads and ironSource, in order to support the purposes listed above.
2.2 Usage data & in-app interactions
We may collect information about how you use the App, for example:
- Screens and sections you view inside the App
- Buttons you tap and features you use (such as setting wallpapers, previewing 3D/4D wallpapers, generating AI images)

- Interactions with ads (impressions, clicks, completions of rewarded ads)
Purpose: to understand App performance, improve user experience and measure the effectiveness and quality of ads and features.
2.3 Log data, diagnostics & crash reports
Through analytics and crash reporting tools (such as Firebase Analytics and Firebase Crashlytics), we may collect:

Purpose: to identify problems, fix bugs and keep the App stable and secure.
2.4 User-generated content (wallpapers, images & prompts)
The App allows you to generate, view and apply wallpapers, including 3D & 4D wallpapers and, where available, AI-generated images. Depending on the feature, we may process:
- Wallpapers you preview, download, mark as favourites or apply
- AI prompts and/or reference images you provide for generating images
- Temporary files or cached image data stored on your device
Where required for AI generation or server-side processing, prompts or image data may be sent securely to our servers or to third-party AI service providers only for the purpose of generating the requested output. We do not use this data to personally identify you.
2.5 Push notifications & messaging tokens
If you allow push notifications, a unique device token may be generated and used via services such as Firebase Cloud Messaging.
Purpose: to send notifications about new wallpapers, features, offers, and important updates about the App. You can disable notifications at any time in your device settings.

We do not use these permissions to access your personal photos or files unless you explicitly select a file or image from your device for use in the App (for example, as a reference for AI generation).
4. Third-party services & SDKs
The App integrates third-party libraries and SDKs for advertising, analytics, crash reporting, notifications and media functionality.
