Overtitle 不收集你的任何个人信息，也没有服务器保存你的数据。麦克风录到的声音只在你的设备上处理，从不上传、从不存盘。 Overtitle collects no personal information and runs no server that stores your data. Audio from the microphone is processed entirely on your device. It is never uploaded and never written to disk.
开始同步后，Overtitle 用麦克风听电影对白，交给 iOS 内置的设备端语音识别，把听到的词和你选的字幕文件比对，从而判断电影演到了哪里。整个过程在设备上完成。音频不会被录制成文件，不会离开设备，也不会发给我们或任何第三方。识别在锁定字幕位置后即停止。 While syncing, Overtitle uses the microphone to hear the film’s dialogue and passes it to the on-device speech recognition built into iOS. The recognized words are matched against the subtitle file you chose in order to work out where in the film you are. All of this happens on your device. Audio is never recorded to a file, never leaves the device, and is never sent to us or to any third party. Recognition stops once the position is locked.
你导入或下载的字幕文件、你的偏好设置，以及（如果你填了）你的 OpenSubtitles 账号密码，都保存在你自己的设备上。账号密码存放在 iOS 钥匙串中。删除 App 会一并删除这些数据。 Subtitle files you import or download, your preferences, and your OpenSubtitles credentials if you enter them are all stored on your own device. Credentials are kept in the iOS Keychain. Deleting the app removes all of it.
搜索影片和字幕时，App 会直接向以下服务发起请求。这些请求包含你搜索的片名或影片编号，不包含你的身份信息；我们不经手、也不留存这些请求。 When you search for films or subtitles, the app talks directly to the services below. Those requests contain the title or film ID you searched for, not your identity. We neither proxy nor retain them.
TMDB（影片资料与海报）、OpenSubtitles.com（字幕搜索与下载）。如果你登录了 OpenSubtitles 账号，你的用户名和密码会直接发给 OpenSubtitles 用于登录。它们各自的隐私政策适用于这些请求。 TMDB, for film metadata and artwork. OpenSubtitles.com, for subtitle search and download. If you sign in, your OpenSubtitles username and password are sent directly to OpenSubtitles to authenticate. Their respective privacy policies apply to those requests.
没有。App 里没有分析 SDK、没有崩溃上报、没有广告、没有跨 App 追踪。 None. There is no analytics SDK, no crash reporting, no advertising, and no cross-app tracking.
App 内的打赏由 Apple 处理。我们看不到你的支付信息。 The in-app tip is handled by Apple. We never see your payment details.
