Background Wizard Privacy Policy

App: Background Wizard (background.erase.replace.change.blur.remove) · Developer: Zettelabs · Effective: 22 October 2026 · Applies to version 2.0 and later

This policy explains what information Background Wizard handles, why, and the choices you have. Background Wizard does not require an account and does not ask for your name, email address, phone number or contacts.

1. Your photos stay on your device

You choose each photo yourself, through the Android photo picker or by taking a new picture with your camera app. Background Wizard only receives the photos you pick; it cannot browse the rest of your gallery.

Finding the subject, removing or replacing the background and blurring all happen on your device, using Google's on-device ML Kit. Your photos and edits are never uploaded to us or to any third party. An edited photo is written to your gallery (in a "Background Wizard" album) only when you tap Save. When you share a photo, a temporary copy is kept in the app's private cache so the app you share to can read it.

2. Permissions

PermissionWhy
InternetTo download background images, and to load ads, app configuration, analytics and crash reports (see below). Photos are never sent.
Storage (WRITE_EXTERNAL_STORAGE, Android 9 and older only)To save your edited photo to the gallery on older Android versions. Newer versions need no permission for this.

Background Wizard does not request camera, microphone, contacts, location or photo-library permissions. Taking a picture opens your own camera app.

3. Background images

The Replace tool's background images are downloaded from the jsDelivr content delivery network (cdn.jsdelivr.net). Like any website, the CDN receives your IP address and basic request information when an image is downloaded. Nothing about your photos is sent with these requests.

4. Information collected by third-party services

Background Wizard is free and supported by ads. It uses the following Google services, which may collect information automatically from your device:

ServicePurposeData it may collect
Google AdMobShowing ads (app open, interstitial, native and rewarded ads)Advertising ID, IP address, device and app information, ad interactions
Google User Messaging PlatformAsking for and storing your ad consent where required by lawYour consent choices, device information
Google ML Kit (subject segmentation)Finding the subject in your photo, on your deviceThe model runs on your device; Google Play services may download the model and collect usage and diagnostic information about the API. Your photos are not sent.
Firebase AnalyticsUnderstanding how the app is used (for example, which tools are opened) so we can improve itApp usage events, app instance ID, device and app information, approximate location derived from IP
Firebase CrashlyticsDiagnosing crashesCrash logs, device state at the time of the crash, app instance ID
Firebase Remote ConfigAdjusting app settings, such as ad frequency, without an updateApp instance ID, device and app information

These services are governed by their own policies: Google Privacy Policy, How Google uses information from apps that use its services, ML Kit terms and Firebase privacy information.

We do not sell your personal information. Data is transmitted over encrypted connections (HTTPS).

5. Your choices

Ad consent: If you are in the EEA, UK or Switzerland, or another region where consent is required, Background Wizard asks for your consent before showing personalized ads. You can change your choice at any time from Privacy settings on the Home screen.

Advertising ID: You can reset or delete your advertising ID in Android Settings › Privacy › Ads.

Deleting data: Uninstalling Background Wizard or clearing its storage removes all data the app keeps on your device. Photos you saved stay in your gallery until you delete them. To request deletion of analytics data linked to your app instance, contact us at the address below.

6. Data retention

The app keeps only small settings (such as whether you have seen the introduction) and temporary share copies on your device. Firebase Analytics data is retained for up to 14 months; Crashlytics crash data for up to 90 days. Advertising data is retained according to Google's policies.

7. Children

Background Wizard is not directed at children under 13 and we do not knowingly collect personal information from them. If you believe a child has provided information through the app, contact us and we will take steps to delete it.

8. Your rights

Depending on where you live (for example under the GDPR, UK GDPR, KVKK or CCPA), you may have the right to access, correct, delete or object to the processing of your personal data, and to withdraw consent. Because we do not hold an account or your photos, most data is held by the Google services listed above; contact us and we will help with any request.

9. Changes to this policy

We may update this policy when the app changes. The new version will be posted on this page with a new effective date.
