This Privacy Policy explains what information Wallivoa ("we", "our", "the app") collects, why, and how it is used. Wallivoa is a wallpaper browsing and download app for Android. Using the app means you agree to the practices described here.
Most of Wallivoa works without an account. The table below lists everything the app can collect and when.
| Data | When | Purpose |
|---|---|---|
| Google account name, email, and profile photo | Only if you choose to sign in with Google | Keep your favorites and premium entitlement tied to your account across devices |
| Favorited wallpapers, download activity, free-action counts | As you use the app | Show your favorites, enforce the free-tier allowance, and unlock rewarded actions |
| Push notification token, notification preferences | If you allow notifications | Deliver new wallpaper, collection, and announcement alerts you've opted into |
| Device attestation signal (Play Integrity) | Automatically, in the background | Confirm requests come from a genuine, unmodified copy of the app - no personal data is included |
| App usage events (screens viewed, wallpapers viewed/downloaded, crashes) | Automatically, via Firebase Analytics and Crashlytics | Understand what's working, fix bugs, and improve the app |
| Advertising identifier and ad interaction data | Only when you choose to watch a rewarded ad | Show the ad and verify it was watched, through Google AdMob |
| Subscription purchase status | If you subscribe to Premium | Unlock premium wallpapers, 4K downloads, and an ad-free experience, verified through Google Play Billing |
Wallpaper images themselves are served from our own content delivery network and are not personal data.
You can browse, favorite (locally), and download free wallpapers without signing in. Signing in with Google is only required to keep favorites synced across devices and to restore a Premium subscription on a new device.
We do not sell your personal information. We do not use your data to build advertising profiles beyond what Google AdMob independently does for rewarded ads.
Wallivoa relies on the following third-party services, each governed by its own privacy policy:
Account data and favorites are kept for as long as your account exists. You can delete your account and associated data at any time - see Delete your Wallivoa account for the exact steps, what is erased, and what we are required to keep. Analytics and crash data are retained according to Google Firebase's standard retention periods.
Wallivoa is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, contact us and we will delete it.
All privileged actions (entitlement checks, download authorization, reward grants, purchase verification) are handled by our backend, never trusted from the app alone. Data in transit is encrypted (HTTPS/TLS).
We may update this policy as the app changes. Material changes will be reflected by updating the "Last updated" date above.
