Version: September 19, 2026 · Applies to AI Wallpapers HD - 4K Themes

Wallpapers come from third-party image libraries and the app never reads your gallery; includes ads, analytics, crash reporting, in-app purchases and a report feature.

Scope

This privacy policy applies to the Android app “AI Wallpapers HD - 4K Themes” (package com.wallflow.ai.hd.wallpaper.picker, called WallFlow on this site), published on Google Play by ITeddy. It explains what the app collects, why, who it is shared with, and how you can have it deleted. It matches the Data safety section of the app’s Google Play listing.

What stays on your device

Wallpaper images come from third-party libraries such as Pexels, Unsplash and Pixabay, and from our own image storage. They are downloaded to your device and applied as wallpaper by you. Live effects such as particle nebula and fireworks render locally. The app does not read or upload photos from your gallery.

What we collect

The following data leaves the device to the services we use. Unless stated otherwise it is collected automatically and contains no name, email address or phone number.

  • App interactions and other actions (Firebase Analytics): which screens you open, which features you use and in-app events, together with an app-instance ID, device model, OS version, language and country/region. None of this includes your name or contact details.
  • Crash logs and diagnostics (Firebase Crashlytics): stack traces, device and OS information at the time of a crash, and app state, used to find and fix faults.
  • Device or other IDs: the advertising ID (AdMob), the Firebase app-instance ID and a random anonymous user ID generated by RevenueCat. None of these identify you by name, and the advertising ID can be reset in system settings.
  • Purchase history (RevenueCat and Google Play Billing): which item you bought or subscribed to, when, and its status, used to unlock paid features and restore purchases. Google Play handles payment; we never see your card or bank details.
  • Content you choose to send: when you report a wallpaper or submit feedback, the text you write, the reason, and the ID and source of the reported wallpaper are stored in our cloud database (Firebase Cloud Firestore) so we can act on it. This is optional.
  • Install source (Google Play Install Referrer): read once on first launch to attribute the install to a promotion channel.

How we use it

  • Providing and maintaining app features, such as unlocking paid features, restoring purchases and enforcing free allowances.
  • Measuring how features are used so we know what to improve.
  • Finding and fixing crashes and faults.
  • Serving ads and measuring their performance.
  • Verifying purchases and preventing fraud and abuse.

Third-party services and sharing

We do not sell your personal information. The services below process data under their own privacy policies: Google AdMob receives the advertising ID, device diagnostics and in-app interaction data to serve and measure ads; Firebase and RevenueCat act as our service providers and process data only on our behalf.

Permissions

  • Network: to download wallpapers, and for ads, usage statistics, crash reporting and purchase verification.
  • Set wallpaper: to apply the image you choose to your home or lock screen.
  • Run at boot, ignore battery optimisation (optional): only when you turn on automatic wallpaper changes, so the schedule keeps running.
  • Notifications (optional): auto-change and download notices.
  • Storage write (Android 9 and below only): to save wallpapers to your device.

Retention and deletion

Data stored on the device is removed when you uninstall the app. Server-side data you can ask us to delete: Analytics, crash and purchase records linked to your app-instance ID, advertising ID or RevenueCat anonymous ID, plus any reports or feedback you submitted.

To request deletion, email dola724gg@gmail.com and mention the app name “AI Wallpapers HD - 4K Themes”. We handle requests within 30 days. You can also reset or delete your advertising ID in system settings at any time.

Your choices

  • In the EEA, UK and Switzerland the app shows an ad-consent prompt on first launch, where you can decline personalised ads.
  • In system settings under Google › Ads you can opt out of ad personalisation or reset the advertising ID.
  • Purchases and subscriptions can be managed or cancelled from the Subscriptions page in Google Play.

Security

All network traffic uses HTTPS or an equivalent encrypted connection. We never store your photos, documents or payment details on servers of our own.

Children

The app is intended for a general adult audience and is not directed at children under 13. We do not knowingly collect personal information from children; if we learn we have done so, we delete it promptly.

Changes to this policy

Updates are published on this page with a new version date; material changes are also noted in the app’s release notes.
