Privacy Policy
This Privacy Policy explains how Donkor (“we”, “us”) handles information
in the Demon Slayer's Wallpaper mobile app
(package com.qiaotou.guming.wallpaper.demon.slayer, the “App”). The App does not
require you to create an account.
1. Information we collect
- Device identifier. We use your Android ID to check whether a membership or VIP status is active on your device. It is not used to identify you by name.
- Advertising identifier and device information. Our advertising partners, Google AdMob and AppLovin, may collect your advertising ID, IP address, device model, operating system version, and ad interaction data to serve and measure banner, interstitial, and rewarded ads.
- Purchase information. If you subscribe to VIP through Google Play, the App receives your subscription status from Google Play so it can unlock VIP features. Google handles payment processing; we do not receive your payment card details.
- Server logs. Our servers may record your IP address, request time, app version, and basic request data to keep the service secure and working. These logs are kept for a limited period.
- Support messages. If you email us, we receive your email address and the contents of your message so we can reply.
Favorites and app preferences are stored locally on your device using Android DataStore; they are not uploaded to our servers. Wallpapers you save are stored in your device gallery; we do not upload them. The App does not collect your name, precise location, contacts, camera, microphone, or your photo library.
2. How we use information
- To provide wallpapers, previews, favorites, and sharing.
- To save wallpapers to your gallery and set them as your home or lock screen wallpaper.
- To check whether a membership or VIP subscription is active.
- To display and measure ads. Rewarded ads may unlock certain actions for non-VIP users.
- To process subscriptions through Google Play.
- To respond to support requests and keep the service secure.
The App requests the following Android permissions:

- Set wallpaper: apply a wallpaper to your home or lock screen.
- Storage access on older Android versions: save and share wallpapers.

4. Data retention
Membership records are kept while the membership is active and for a reasonable period afterwards for support and accounting. Server logs are kept for a limited period. Advertising and purchase data are retained by Google and AppLovin according to their own policies. Local favorites and preferences are removed when you uninstall the App or clear its data.
5. Security
We use HTTPS, access controls, and other reasonable measures to protect the service. No method of transmission or storage is completely secure, but we work to protect your information.

We will respond within a reasonable time, usually within 30 days.

We may update this policy from time to time. The “Last updated” date at the top of this page shows when it was last revised. Continued use of the App after an update means you accept the revised policy.
