流影（FlowPlayer）是一款个人音视频播放器。本政策说明应用如何处理你选择的媒体及相关信息，以及你主动联系我们时的信息处理方式。
1. 保存在设备上的信息
媒体索引、文件书签、播放进度、最近记录、收藏、播放队列、歌单及设置保存在你的设备上。你主动复制或通过 Finder 传入的文件保存在应用文件目录中。应用没有账号系统、CloudKit 同步或开发者自建的媒体服务器。本地数据和用户文件可能受设备备份或系统迁移设置影响；我们不承诺所有数据都排除备份。
2. 你选择的文件和网络来源
应用通过系统文件选择器访问你授权的文件，并保存恢复访问所需的文件书签；直接打开的外部文件通常保留在原位置。iCloud 或其他文件提供商可能为读取所选文件而下载或同步数据，其处理方式由对应服务决定。添加网络媒体地址时，应用会验证地址；添加成功后会启动播放并请求媒体。验证地址、播放或继续缓存时，你指定的服务器可能接收到 IP 地址、请求地址、时间及必要请求信息；即使添加失败、尚未开始播放，地址验证也可能已发出网络请求。我们无法控制这些来源的日志或隐私做法。
3. 播放缓存和明确保存的视频
网络播放使用应用私有缓存，可在稍后播放时继续有效的部分缓存；私有媒体缓存排除设备备份。你明确保存的合资格网络视频是应用文件目录 Saved Videos 中的独立普通文件，可能参与系统备份或 Finder 文件共享。删除网络媒体记录会清理其私有缓存和进行中的保存任务，但不会删除已经保存的独立视频文件。
4. 系统播放功能
为提供锁屏控制、后台音乐和系统媒体控制，应用会向系统提供当前媒体的标题、艺术家、进度等必要信息。文件提供商、AirPlay、画中画及其他系统服务按你的操作和系统规则工作。
5. 广告、追踪和诊断
应用未集成广告、分析或追踪 SDK，不进行跨应用行为追踪，也没有自动诊断上传功能。本地诊断使用固定类别及会话标识，不以用户媒体名称或完整来源地址作为日常日志内容。系统服务可能按其自身设置处理诊断信息。
6. 你主动联系我们
邮件和 Telegram 入口仅在你点击后交给系统或外部应用；流影不会自动发送消息，也不会预填你的媒体文件或附件。你决定是否发送内容。我们使用你主动提供的信息答复支持请求，不保存、不转发这些消息，也不用于营销。邮件及 Telegram 服务自身对消息的处理和留存受各自规则约束；上述承诺不表示这些服务不会留存消息。
7. 管理和删除
你可以在应用中清除最近播放历史、删除媒体记录或删除应用内文件。清除历史不会删除媒体文件；删除文件会移除对应的实际内容，请按界面操作。删除 App 会移除设备上的应用容器数据，外部原文件和系统备份需分别管理。我们没有供你注销的应用账号或开发者服务器媒体库。
8. 联系和政策更新
隐私问题可联系 biyuhuaping@gmail.com 或 Telegram @biyuhuaping。本政策内容变更时会更新本页及更新日期。用于展示本政策的托管服务可能按自身规则处理网页访问请求；应用内的媒体和播放记录不会因打开本页而自动附加到请求中。

FlowPlayer is a personal audio and video player. This policy explains how the app handles media you choose, related information, and information you voluntarily provide when contacting us.
1. Information on your device
Your media index, file bookmarks, playback progress, recent history, favorites, queue, playlists and settings are stored on your device. Files you explicitly copy or transfer through Finder are stored in the app's file directory. The app has no account system, CloudKit synchronization or developer-operated media server. Local data and user files may be included in device backups or system migration; we do not promise that all data is excluded from backup.
2. Files and network sources you choose
The app uses the system document picker to access files you authorize and stores file bookmarks to restore access. External files opened directly usually remain in their original location. iCloud or other file providers may download or synchronize selected files under their own service rules. Adding a network media address validates the address; a successful addition starts playback and requests media. During address validation, playback or cache continuation, your chosen server may receive your IP address, requested address, time and necessary request information. Validation may already have made network requests even if adding the address fails and playback never starts. We do not control those sources' logs or privacy practices.
3. Playback cache and explicitly saved videos
Network playback uses a private app cache and may continue valid partial caches during later playback. The private media cache is excluded from device backup. Eligible network videos you explicitly save become independent regular files in Saved Videos in the app's file directory and may participate in system backup or Finder file sharing. Deleting a network media record clears its private cache and ongoing save work, but does not delete an independent video already saved.
4. System playback features
To provide lock-screen controls, background music and system media controls, the app supplies necessary current-media information, such as title, artist and progress, to the system. File providers, AirPlay, Picture in Picture and other system services operate in response to your actions and system rules.
5. Advertising, tracking and diagnostics
The app includes no advertising, analytics or tracking SDK, performs no cross-app behavioral tracking and has no automatic diagnostics-upload feature. Local diagnostics use fixed categories and session identifiers rather than user media names or complete source addresses in routine logs. System services may process diagnostics according to their own settings.
6. Voluntary support contact
Email and Telegram entries hand off to the system or an external app only after you tap them. FlowPlayer does not send messages automatically or prefill your media files or attachments. You choose whether and what to send. We use information you voluntarily provide to answer support requests; we do not save or forward those messages or use them for marketing. Email and Telegram services process and retain messages under their own rules; our commitment does not mean those services do not retain messages.
7. Managing and deleting information
You can clear recent playback history, remove media records or delete files within the app. Clearing history does not delete media files. Deleting a file removes its actual contents, as indicated by the interface. Deleting the app removes its on-device container data; external originals and system backups must be managed separately. There is no app account to close or developer-server media library to delete.
8. Contact and policy updates
For privacy questions, contact biyuhuaping@gmail.com or Telegram @biyuhuaping. We update this page and its date when the policy changes. The service hosting this policy may process page requests under its own rules. Opening this page does not automatically attach your in-app media or playback history to the request.
