ScreenVideo 隐私政策
ScreenVideo Privacy Policy

生效日期 / Effective date: 2026 年 10 月 13 日 / October 13, 2026

屏幕录像与本机保存 / Recordings and local storage

ScreenVideo 根据您的设置捕捉所选屏幕或窗口、电脑声音、麦克风声音和摄像头画面。录像默认保存到 Mac 的应用支持文件夹；您也可以在应用中选择其他保存位置。ScreenVideo 不会在您开始录制前捕捉画面或声音。请妥善管理本机录像文件和备份。

ScreenVideo captures the selected screen or window and, when enabled, system audio, microphone audio, and camera video. Recordings are saved on your Mac, by default in the app’s Application Support folder; you may choose another folder in the app. ScreenVideo does not capture screen or audio before you start a recording. You control the local files and backups.

权限 / Permissions

macOS 会在录制屏幕、使用麦克风或使用摄像头时要求相应权限。您可在系统设置中撤销这些权限。录像中可能包含您屏幕上显示的个人或机密信息，请在录制和分享前检查内容。

macOS requests the relevant permissions for screen recording, microphone use, or camera use. You can revoke these permissions in System Settings. A recording may include personal or confidential information visible on your screen; review it before sharing.

嵌入式网页和第三方服务 / Embedded websites and third-party services

应用内浏览器可显示 YouTube 等第三方网页。访问这些页面时，第三方服务会依其自身隐私政策处理网络请求和相关数据。ScreenVideo 不控制这些服务。

The in-app browser can display third-party pages such as YouTube. When you visit them, those services process network requests and related data under their own privacy policies. ScreenVideo does not control those services.

TikTok 草稿上传 / TikTok draft upload

当您主动连接 TikTok 时，ScreenVideo 会通过 TikTok Login Kit 请求 user.info.basic 与 video.upload 权限，并读取 TikTok 返回的 Open ID 和可用的显示名称。您每次选择一个本机 MP4 并点选上传后，ScreenVideo 会直接将该文件分块传给 TikTok 的上传地址，创建收件箱草稿；ScreenVideo 后端不会接收或保存视频文件。您必须在 TikTok 内检查、编辑并自行发布。为完成 OAuth 令牌交换、刷新令牌以及创建用户请求的草稿，ScreenVideo 的 Cloudflare 后端会保存设备标识、设备密钥的哈希值、TikTok Open ID、令牌更新时间，以及经 AES-GCM 加密的 TikTok 访问令牌和刷新令牌。设备密钥保存在 macOS Keychain。令牌密钥与 TikTok 客户端密钥仅保存在后端 Worker Secrets，不写入应用或网页代码。断开连接时，ScreenVideo 会请求 TikTok 撤销令牌并删除后端关联记录；令牌过期后可能需要重新授权。TikTok 对登录、账户资料及已上传视频的处理由 TikTok 自身政策管理。

When you choose to connect TikTok, ScreenVideo uses TikTok Login Kit to request user.info.basic and video.upload permission and receives your TikTok Open ID and available display name. When you select a local MP4 and choose upload, ScreenVideo sends that file directly in chunks to TikTok’s upload URL to create an inbox draft. The ScreenVideo backend does not receive or store video files. You must review, edit, and publish the draft in TikTok. To exchange and refresh OAuth tokens and create drafts you request, ScreenVideo’s Cloudflare backend stores a device identifier, a hash of the device secret, TikTok Open ID, token update time, and TikTok access and refresh tokens encrypted with AES-GCM. The device secret is stored in macOS Keychain. The encryption key and TikTok client secret are stored only as backend Worker Secrets, never in the app or website source. When you disconnect, ScreenVideo requests token revocation from TikTok and deletes the backend connection record. Expired authorization may require reconnecting. TikTok’s own policies govern sign-in, profile data, and uploaded videos.
