1. 适用范围
本政策适用于 TTCleaner Android 应用(以下简称“本应用”),说明本应用如何访问、使用、保存与删除信息。
2. 本应用访问的信息
- 照片和视频:经你授权后,本应用通过 Android MediaStore 读取媒体的 URI、名称、大小、日期、类型和内容,用于统计、截图识别、大文件筛选、完全重复内容比较和缩略图展示。
- 你选择的文件夹:当你使用“下载内容”功能时,Android 系统文件夹选择器会让你选择一个目录。本应用只访问系统授予的该目录及其子目录。
- 设备存储概况:本应用读取设备总空间和可用空间,用于展示存储概况。
- 本地应用数据:本应用在设备上保存主题、扫描选项、首次使用状态、滑动整理决定,以及清理记录的时间、项目数量和大小。
清理记录不保存文件名、文件路径、照片内容或视频内容。
3. 信息如何使用
上述信息仅用于提供你主动使用的扫描、预览、选择、清理、历史记录和设置功能。媒体扫描、文件哈希比较和整理逻辑均在设备本地执行。
4. 数据传输、共享与第三方服务
本应用不将你的应用数据传输给 TTCleaner 开发者或第三方,不出售或共享个人信息,也不包含广告、用户行为分析、崩溃上报 SDK、无障碍服务或后台账号系统。点击本应用中的隐私政策入口会交由你选择的浏览器打开本网页;浏览器与托管服务可能按照各自政策处理常规网络请求信息。
5. 权限说明
- 照片和视频权限:仅在需要读取媒体库时请求。Android 14 及更高版本支持仅授权你选择的媒体。
- 系统文件夹授权:普通文件通过 Android Storage Access Framework 授权,不请求“管理所有文件”权限。
拒绝或撤销权限不会阻止你使用不依赖该权限的功能。
6. 删除、保留与控制
- 媒体项目只会在你选择项目并通过 Android 系统确认后移至系统回收站。
- 普通文件在永久删除前会显示明确确认;永久删除不可撤销。
- 你可以在系统设置中随时撤销媒体或文件夹访问权限。
- 应用设置、整理决定和清理历史保存在本地,直到你清除应用数据或卸载应用。
7. 数据安全
本应用遵循 Android 权限与系统选择器的访问边界,并尽量减少保存的数据。任何软件都无法保证绝对安全,但本应用通过本地处理和不建设数据接收服务器来降低风险。
8. 儿童隐私
本应用不以儿童为目标,也不会有意收集儿童的个人信息。由于本应用不运营数据收集服务,我们不会建立儿童个人资料。
9. 政策更新
功能或法律要求发生变化时,我们可能更新本政策。更新后的版本会发布在本页面,并修改生效日期。

Effective date: September 25, 2026
Summary: TTCleaner scans and organizes content locally on your Android device. We do not operate a server that receives app data, serve advertising, or integrate Analytics or Crashlytics. The app does not upload your photos, videos, filenames, scan results, or usage activity.
1. Scope
This policy applies to the TTCleaner Android application (the “App”) and explains how the App accesses, uses, stores, and deletes information.
2. Information the App accesses
- Photos and videos: With your permission, the App uses Android MediaStore to access media URIs, names, sizes, dates, types, and content for storage statistics, screenshot detection, large-file filtering, exact duplicate comparison, and thumbnail display.
- Folders you select: When you use Downloads, Android's system folder picker lets you choose a directory. The App can access only that system-authorized directory and its subdirectories.
- Device storage overview: The App reads total and available device space to display a storage overview.
- Local app data: The App stores your theme, scan options, onboarding state, swipe-review decisions, and the time, item count, and size of cleaning operations on the device.
Cleaning history does not store filenames, file paths, photos, or video content.
3. How information is used
This information is used only to provide the scanning, preview, selection, cleaning, history, and settings features you choose to use. Media scanning, file-hash comparison, and organization logic run locally on the device.
4. Data transfer, sharing, and third parties
The App does not transmit your app data to the TTCleaner developer or third parties, sell or share personal information, or include advertising, behavioral analytics, crash-reporting SDKs, accessibility services, or an account system. Selecting the Privacy Policy entry in the App asks your chosen browser to open this page; the browser and hosting provider may process ordinary web-request information under their own policies.
5. Permissions
- Photos and videos: Requested only when media-library access is needed. Android 14 and later can limit access to media you select.
- System folder access: Ordinary files are authorized through the Android Storage Access Framework. The App does not request All files access.
Denying or revoking a permission does not prevent you from using features that do not depend on it.
6. Deletion, retention, and your controls
- Media items move to the system trash only after you select them and confirm the Android system prompt.
- The App displays an explicit warning before permanently deleting ordinary files. Permanent deletion cannot be undone.
- You can revoke media or folder access at any time in Android settings.
- App settings, review decisions, and cleaning history remain locally until you clear the App's data or uninstall it.
7. Security
The App follows Android permission and system-picker boundaries and minimizes stored data. No software can guarantee absolute security, but local processing and the absence of a developer-operated data-ingestion server reduce exposure.
8. Children's privacy
The App is not directed to children and does not knowingly collect children's personal information. Because the App does not operate a data-collection service, we do not create profiles of children.
9. Changes to this policy
We may update this policy when features or legal requirements change. The revised version will be published on this page with an updated effective date.
