Video Toolbox lets you trim, compress, convert to GIF, extract audio, remove sound, rotate and flip, change speed, merge videos and save frames as photos.

We do not collect any personally identifiable information, nor do we collect device identifiers, location, contacts or usage data. The app has no account system; all features work without signing in.

The app does not request the internet permission. It is technically unable to send your videos or any other data to our servers, and we have no access to your videos.

You choose the videos to work on in the system photo picker (or the system file picker on some phones). The app can only read the videos you choose; it cannot browse your gallery or other files.

Decoding, encoding, trimming and merging all happen on your phone using Android's built-in media codecs. Temporary files created during processing are kept in the app's cache folder and deleted once the result is saved or when the next job starts.

Results are saved to your phone's shared media folders: videos to Movies/Video Toolbox, audio to Music/Video Toolbox, and GIFs and photos to Pictures/Video Toolbox. These files belong to you and are not removed when you uninstall the app; you can view, move or delete them in your gallery or file manager.

The app remembers your recent exports on the home screen (file name, type, size and export time) so you can open or share them again. You can remove an item from the list or delete the file at any time. This list and the app settings are kept in the app's private storage and may be included in the Android system backup to your own Google account (depending on your backup settings). We have no access to those backups.

The app does not request internet, camera, microphone, location or contacts permissions.

Only on phones running Android 9 or earlier, the app asks for the storage permission so it can save results to the shared folders above. Android 10 and later do not need this permission.

Notifications: while a video is being processed, the app shows its progress and a Cancel button in a notification, and tells you when the result is ready. If you deny this permission, processing still works; you just will not see these notifications.

Foreground service and keeping the device awake: used only while a video is being processed, so the work continues when you switch to another app or lock the screen. They stop as soon as processing finishes or is cancelled.

A file is passed to another app only when you tap Share or Open and choose that app in the system share sheet or app chooser. That app handles the data under its own privacy policy.

The app uses Google's open-source AndroidX Media3 libraries to process and play videos on the device. These libraries do not connect to the internet or collect any data. The app does not include any advertising, analytics or crash-reporting SDKs.

The app is distributed through Google Play. Depending on your device settings, Google may collect diagnostic information such as installs and crashes, which is governed by the Google Privacy Policy (https://policies.google.com/privacy).

The app is not directed at children under 13, and it does not collect personal information from any user, including children.

We may update this policy when the app, the law or our operations change. The updated policy will be published on this page with a new effective date. If a new version materially changes how data is handled, we will notify you prominently in the app.

If you have any questions or requests about this policy or your privacy, please contact us at [email protected].

本应用未申请网络权限，技术上无法把您的视频或任何数据发送到我们的服务器，我们也无法访问您的视频。

您通过系统照片选择器（部分手机上为系统文件选择器）选择要处理的视频，本应用只能读取您选中的视频，无法浏览您的相册或其他文件。

视频的解码、编码、剪辑和合成都在您的手机上通过 Android 系统的媒体编解码器完成。处理过程中产生的临时文件保存在本应用的缓存目录，保存完成或下次处理时会被删除。

处理结果保存到手机的公共媒体目录：视频保存在 Movies/Video Toolbox，音频保存在 Music/Video Toolbox，GIF 和照片保存在 Pictures/Video Toolbox。这些文件属于您，卸载本应用不会删除它们，您可以在相册或文件管理器中查看、移动或删除。

本应用会在首页记住最近导出的文件（文件名、类型、大小和导出时间），方便您再次打开或分享。您可以随时从列表中移除某一项，或直接删除对应的文件。这份列表和应用设置保存在本应用的私有存储中，并可能随 Android 系统备份一起备份到您自己的 Google 账号（取决于您的系统备份设置）。我们无法访问这些备份数据。

本应用不申请网络、相机、麦克风、位置、通讯录等权限。

仅在 Android 9 及更早版本的手机上，本应用会申请「存储」权限，用于把处理结果保存到上述公共文件夹；Android 10 及以上版本无需此权限。

「通知」权限：处理视频时在通知栏显示进度和「取消」按钮，处理完成时提示结果。拒绝此权限不影响处理，只是看不到这些通知。

前台服务和「保持唤醒」：只在处理视频期间使用，让处理在您切换到其他应用或锁屏时继续进行，处理结束或取消后立即停止。

只有在您点击「分享」或「打开」时，应用才会通过系统分享面板或系统打开方式，把文件交给您选择的应用。相关应用对数据的处理适用其自身的隐私政策。

本应用使用 Google 开源的 AndroidX Media3 组件在本地处理和播放视频，该组件不联网，也不收集任何数据。本应用不集成任何广告、统计分析或崩溃上报等第三方 SDK。
