Privacy Policy
Last updated 9 October 2026 · Wallmaa: Minimal Wallpapers (com.wallmaa.minimal.wallpapers) · Published by Bract Studio
Wallmaa is a minimal wallpaper app. It does not ask you to create an account, and it does not ask for your name, email, contacts, photos or location. The app shows ads, and its ad partners use your device's advertising ID to do that. This page explains what is collected, why, and who receives it.
1. Summary
Collected: your device's advertising ID, plus basic device and ad-interaction data gathered by our ad partners.
Shared with: Meta Audience Network and Unity LevelPlay (ironSource) for ads, and RevenueCat for purchase and ad-revenue reporting.
Not collected: your name, email address, contacts, photos, files or precise location.
Not sold by us for money.
2. Information collected
- Advertising ID — the resettable ID that Google Play services provides on Android. Ad partners use it to show ads, limit how often you see the same ad, measure ad performance and prevent fraud. If you choose to, it may also be used to show more relevant ads.
- Device and ad-interaction data — collected by the ad SDKs when an ad loads. This usually includes device model, operating-system version, language, network type, IP address (used to estimate a rough region, not your precise location), and whether an ad was shown, clicked or a reward video was completed.
- App and purchase data — RevenueCat assigns the app an anonymous user ID and records purchases or subscriptions made through Google Play, and ad-revenue events. Payments are handled entirely by Google Play; we never see your card or payment details.
- Wallpapers you use — wallpapers are downloaded to your device and applied on your device. Your choices and settings stay on your phone.
3. Who we share it with
Data goes only to the service providers below, for the purposes listed. Each one handles it under its own privacy policy.
| Partner | Purpose | Their policy |
|---|---|---|
| Meta Audience Network | Showing and measuring ads | facebook.com/privacy/policy |
| Unity LevelPlay (ironSource) | Showing and measuring ads, ad mediation | unity.com/legal |
| RevenueCat | Purchases, subscriptions and ad-revenue reporting | revenuecat.com/privacy |
| Google Play | App delivery, payments, advertising ID | policies.google.com/privacy |
4. Your choices
- Reset or delete your advertising ID — open Android Settings → Privacy → Ads (or Settings → Google → Ads on some phones). Deleting it stops apps, including Wallmaa, from using it.
- Turn off personalised ads — use the same settings screen. You will still see ads, but they will be less tailored.
- Stop all collection — uninstall the app.
5. Security and retention
Data is sent over encrypted connections (HTTPS). We do not run our own server that stores your data, and we do not hold any account for you. Our partners keep data for as long as their own policies describe.
6. Deleting your data
Because Wallmaa has no accounts, we hold nothing that is linked to your name. To remove the link between your device and past ad activity, delete or reset your advertising ID as described above. You can also contact the partners in section 3 directly, or email us and we will help.
7. Children
Wallmaa is not directed at children under 13, and we do not knowingly collect data from them. If you believe a child has used the app and data was collected, email us and we will help remove it.
8. Your rights
Depending on where you live (for example under the GDPR in the EU and UK, or the CCPA in California), you may have the right to access, correct or delete personal data, or to object to its use for advertising. Email us to make a request.
9. Changes
If this policy changes, we will update this page and the date at the top.
