📣 广告与同意管理
WallJoy 使用 Google Mobile Ads 展示广告，并使用 Google User Messaging Platform（UMP）在适用地区收集和管理广告隐私选择。根据您的选择、设备设置和 SDK 配置，Google 可能处理设备标识符、IP 地址推断的粗略地区、广告互动及诊断信息，用于广告投放与衡量、防止欺诈和服务稳定性。您可以在应用设置中重新打开广告隐私选项；是否提供个性化广告由适用法律、您的选择和 Google 的处理规则共同决定。
🌐 网络请求
应用会连接 Pixabay 完成图片搜索与下载，并通过 Google Mobile Ads/UMP 提供广告及适用地区的同意流程。
💾 本地存储
应用会在设备本地缓存浏览过的图片以提升加载速度。您的收藏数据仅保存在设备本地，不会上传至任何服务器。您可以在设置中随时清除缓存数据。
📸 相册权限
当您选择保存壁纸时，应用会请求相册写入权限。此权限仅用于将壁纸保存到您的相册，不会读取您的现有照片。
🧹 保留、删除与撤回同意
收藏、浏览偏好和图片缓存保存在您的设备本地。您可以在设置中清除图片缓存，并在适用地区重新管理广告隐私选择；卸载应用会删除应用保存的本地数据。WallJoy 不维护用户账号或用于存放收藏的服务器，因此没有可由我们远程删除的账号数据。第三方服务处理数据的保留和删除规则以其各自隐私政策为准。
👶 儿童隐私
本应用不是面向13岁以下儿童设计的服务。Pixabay 请求已启用 SafeSearch，但在线内容和第三方广告仍可能动态变化。我们不会故意要求儿童提交个人信息；监护人如认为儿童通过本应用提供了信息，请联系我们。

📣 Advertising and Consent
WallJoy uses Google Mobile Ads to display ads and Google User Messaging Platform (UMP) to collect and manage advertising privacy choices where required. Depending on your choices, device settings, and SDK configuration, Google may process device identifiers, coarse location inferred from an IP address, ad interactions, and diagnostic information for ad delivery and measurement, fraud prevention, and service reliability. You can reopen advertising privacy options in the app's Settings where available. Personalized advertising depends on applicable law, your choices, and Google's processing rules.
🌐 Network Requests
The app communicates with Pixabay for image search and downloads, and with Google Mobile Ads/UMP for advertising and applicable consent flows.
💾 Local Storage
The app caches browsed images locally to improve loading speed. Your favorites data is stored only on your device and is never uploaded to any server. You can clear cached data at any time in Settings.
📸 Photo Library Permission
When you choose to save a wallpaper, the app requests write access to your photo library. This permission is only used to save wallpapers and does not read your existing photos.
🧹 Retention, Deletion, and Withdrawal
Favorites, browsing preferences, and image cache data are stored locally on your device. You can clear the image cache and reopen advertising privacy choices where available from Settings. Uninstalling the app removes data stored locally by the app. WallJoy does not maintain user accounts or a server containing your favorites, so there is no account data for us to delete remotely. Third-party retention and deletion practices are governed by each provider's privacy policy.
🔗 Third-Party Services
Third-party network services are Pixabay for image content and Google Mobile Ads/UMP for advertising and applicable consent flows. Each provider processes data under its own privacy terms.
👶 Children's Privacy
This app is not designed for children under 13. Pixabay requests use SafeSearch, but online content and third-party ads can change dynamically. We do not knowingly ask children to submit personal information. A parent or guardian who believes a child has provided information through the app may contact us.
