Joker & his Girlfriend ("the app") is a free wallpaper app made by ZMR Developers ("we", "us"). The app is supported by ads. This policy explains what information is handled when you use the app, who handles it and the choices you have.
In short: we don't ask for your name, email or any account, and we don't run servers that store information about you. Ads in the app are provided by Google AdMob, which collects some device information as described below.
We do not collect, store or sell personal information. The app has no sign-in, no accounts and no forms, and it never asks for your name, email address, phone number, contacts, photos or precise location.
The only information the app keeps is stored on your own device (see "Information stored on your device"). Information collected for ads is collected by Google, not by us (see "Advertising").
The app shows banner, full-screen (interstitial) and app open ads through Google AdMob. To show and measure ads and to prevent fraud, Google may collect and use:
Your device's advertising ID
Your IP address and approximate location derived from it
Device and app information, such as device model, operating system version and app version
How you interact with ads, such as views and taps
Depending on your choices and where you live, ads may be personalised (based on your interests) or non-personalised. Google's use of this information is covered by Google's Privacy Policy and its explanation of how Google uses information from apps that use its services:
https://policies.google.com/privacy
https://policies.google.com/technologies/partner-sites
Your ad choices and consent
If you are in the European Economic Area, the United Kingdom, Switzerland or another region where consent is required, the app shows Google's consent message before any ads are requested, so you can accept or refuse the use of your data for ads.
You can change your choice at any time from the app's menu (⋮) → Privacy settings. This option appears in regions where it is required.
On any Android device you can also reset or delete your advertising ID, or opt out of personalised ads, in your phone's Settings → Privacy → Ads (or Settings → Google → Ads, depending on your device).
The wallpapers and the list of wallpapers are downloaded from GitHub (raw.githubusercontent.com), where we host them. As with any website, GitHub receives your IP address and basic request information when the app downloads these files. We do not receive or store this information. GitHub's privacy statement:
https://docs.github.com/site-policy/privacy-policies/github-general-privacy-statement
The app needs an internet connection to show wallpapers and does not work offline.
Information stored on your device
The following stays on your phone and is never sent to us:
Your favourite wallpapers
Downloaded wallpaper images kept in a cache so they load faster
App settings, such as whether you have already seen an update message and your ad consent choice
You can remove all of it by clearing the app's data in your phone's settings or by uninstalling the app.
Internet and network state: to download wallpapers, show ads and detect when you are offline.
Set wallpaper: to set the wallpaper you choose on your home and/or lock screen.
Notifications (Android 13 and later, optional): to tell you when a new version of the app is available.
Storage (Android 11 and earlier only): to save a wallpaper to your gallery when you tap Save.
You can deny or revoke optional permissions in your phone's settings; the rest of the app keeps working.
Update checks and notifications
About every 12 hours, while your phone is online, the app checks the same wallpaper list on GitHub to see whether a newer version of the app is available. If one is and you allowed notifications, you get a notification that opens the app's Google Play page. No information about you is sent as part of this check.
The app relies on these services, each with its own privacy policy:
Data retention and deletion
Because we don't store information about you, there is nothing for us to keep or delete. Information collected by Google for ads is kept and deleted according to Google's policies; you can manage it at https://myadcenter.google.com and by resetting or deleting your advertising ID as described above.
Depending on where you live (for example under the GDPR in Europe and the UK, or US state privacy laws such as the CCPA), you may have the right to access, correct or delete your personal information, to object to or limit its use, and to opt out of the "sale" or "sharing" of personal information for targeted advertising. We do not sell personal information. You can opt out of personalised ads using the choices above, and you can contact us with any request.
The app is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided personal information through the app, please contact us and we will help remove it.
All downloads and ad requests use encrypted connections (HTTPS). No method of transmission or storage is completely secure, but because we don't keep personal information, very little information about you is involved in using the app.
We may update this policy when the app changes. The "Last updated" date at the top shows when it was last changed. Significant changes will also be reflected in the app's Google Play listing.
If you have any questions or requests about this policy or your privacy, contact us at zmr.developers.contact@gmail.com.
