1. Overview

Lumawalls is an Android wallpaper app for browsing, previewing, downloading,

and setting static, live, and Depth Clock wallpapers. The catalog includes

artwork made with modern creative tools, including AI-assisted artwork curated

by Lumawalls. Lumawalls Pro provides the premium benefits described in the app.

Free users may see ads; Pro users do not.

Lumawalls does not require you to provide a name, email address, or profile to

browse the app. Protected backend features may create a Firebase anonymous

account. We do not sell your personal information.

2. Information We Collect or Process

Depending on how you use Lumawalls, we or our service providers may process:

- Anonymous identifiers: a random app-install ID, Firebase installation IDs,

  advertising identifiers where permitted, and a Firebase anonymous user ID

  when a protected backend feature needs authentication. These identifiers do

  not directly contain your name or email address.

- App activity: app opens, categories viewed, searches (logged as query length,

  not search text), wallpaper IDs previewed, downloaded, favorited, or set,

  wallpaper category and target, Pro-screen views, and purchase events.

- Diagnostics and device data: crash traces, app version, device model,

  operating-system information, timestamps, available memory or storage,

  network information, and similar technical details needed to diagnose and

  secure the app.

- Purchase information: product ID, purchase token or transaction status, and

  whether Google Play reports an active or restored Lumawalls Pro entitlement.

  We do not receive your full payment-card details.

- Advertising data for free users: Google AdMob may process advertising ID,

  IP address, device information, approximate location inferred from IP, ad

  diagnostics, consent status, and ad impressions or interactions.

- Support information: your email address and anything you choose to include

  if you contact us or send a bug or deletion request.

- On-device data: favorites, theme, onboarding status, recent searches,

  selected wallpaper, downloaded wallpaper files, cached live videos and depth

  layers/configuration, ad-unlock state, and other app preferences.

3. AI-Assisted Artwork and Earlier AI Features

Some wallpapers in the Lumawalls catalog may be created or enhanced with

generative-AI tools and then selected, edited, or prepared by Lumawalls. The

current app does not ask you to submit prompts, photos, or other content to

generate a wallpaper.

Earlier versions offered AI wallpaper generation. When that feature was used,

the prompt and any optional reference image were sent through the Lumawalls

backend to an AI generation provider to produce the requested image. Related

quota, purchase-redemption, generation-event, and abuse-report records may

remain in Firebase until deleted under our retention process. Legacy purchased

AI-credit records may also be processed so we can provide support.

4. How We Use Information

We use information to:

- Deliver, cache, download, preview, and apply wallpapers.

- Remember favorites, preferences, unlocks, and onboarding completion.

- Provide, verify, and restore Pro access and legacy purchase support.

- Show, limit, personalize where permitted, and measure ads for free users.

- Understand feature usage and improve the catalog and app experience.

- Diagnose crashes and protect Lumawalls against abuse, fraud, and unauthorized

  backend access.

- Respond when you contact us.

5. On-Device Storage and Retention

- Favorites, preferences, selected-wallpaper data, ad unlocks, downloads,

  depth configuration, and onboarding status remain on your device until the

  app removes them, you clear app data, or you uninstall Lumawalls.

- Live wallpaper videos and related files are cached locally so Android can

  continue showing the selected wallpaper. Older cached files may be removed

  automatically to manage storage.

- Analytics, advertising, authentication, purchase-verification, security, and

  crash data are kept according to our operational needs and the retention

  controls or policies of the relevant providers.

- Support correspondence is retained as needed to resolve the request and meet

  legal, accounting, fraud-prevention, or security obligations.

- Verified deletion requests are actioned against identifiable live Lumawalls

  records within 30 days. Provider backups may take longer to expire under the

  provider's backup-retention process.

6. Service Providers

Lumawalls uses service providers that process data on our behalf or under their

own terms, including:

- Google Firebase: Authentication, Firestore, Cloud Storage, Cloud Functions,

  App Check, Analytics, and Crashlytics.

- Google Play: app distribution, Play Integrity signals used by App Check,

  billing, subscriptions, purchase verification, cancellations, and refunds.

- Google AdMob and the User Messaging Platform: ads, ad measurement, fraud

  prevention, and regional consent/privacy choices for free users.

- AI generation providers used by the retired generation feature, when a user

  used that feature in an earlier app version.

These providers may process data in countries other than your own. Their

handling of data is governed by their terms, privacy policies, and applicable

data-transfer safeguards.

7. Advertising and Consent

Free users may see native ads between wallpaper tiles, occasional interstitial

ads when applying a wallpaper, and optional rewarded ads that can unlock an

eligible premium wallpaper on that app installation. Pro users do not see ads.

Watching a rewarded ad is optional.

Where required, Lumawalls uses Google's consent message before requesting ads.

If Google reports that a privacy-options entry point is required in your

region, you can revisit your choices from Settings > Privacy Choices. You can

also manage advertising controls in your Android or Google account settings.

8. Purchases and Subscriptions

Purchases are processed by Google Play. Lumawalls processes the product and

purchase status needed to grant, validate, restore, change, or support an

entitlement. Subscription management, cancellation, and most refund handling

take place through Google Play and are subject to Google Play's terms and

applicable law.

9. Children's Privacy

Lumawalls is not directed to children under 13, and we do not knowingly collect

personal information from children under 13. If you believe a child has

provided personal information, contact us so we can review and delete it.

Higher minimum ages may apply in some countries.

10. Security

We use reasonable technical and organizational safeguards, including encrypted

provider connections, Firebase security rules, anonymous authentication for

protected requests, and Firebase App Check. No transmission or storage system

is completely secure, so we cannot guarantee absolute security.

11. Your Choices and Deletion

You can:

- Change available ad-consent choices in Settings > Privacy Choices.

- Manage advertising controls or reset/delete the advertising ID in device or

  Google settings, where available.

- Remove ads by purchasing Lumawalls Pro.

- Remove local favorites, searches, downloads, cached media, and preferences by

  clearing Lumawalls app data or uninstalling the app.

- Manage or cancel a subscription through Google Play.

- Request deletion of identifiable Lumawalls cloud records from Settings >

  Delete My Data. The prepared email includes available anonymous IDs so we can

  locate the relevant records.

- Contact us to ask about access, correction, deletion, restriction, objection,

  or other privacy rights available under the law that applies to you.

We may need to verify a request and may retain limited records where required

for security, fraud prevention, transactions, legal compliance, or the exercise

or defense of legal claims. Google-controlled purchase, advertising, and other

provider records must be managed under the provider's own process.

12. Disclosure of Information

We disclose information to the service providers described above only as

needed to operate, secure, measure, monetize, and support Lumawalls. We may also

disclose information when required by law, to protect rights or safety, to

investigate fraud or abuse, or as part of a business reorganization subject to

appropriate safeguards. We do not sell personal information.

13. Changes to This Policy

We may update this Privacy Policy as Lumawalls, our providers, or legal

requirements change. We will update the effective date and, where required,

provide an in-app notice or request consent.
