Data collection

Swifty Download Manager (SDM) does not send personal information, browsing activity, download URLs, filenames, usage data, analytics, or telemetry to the developer and does not sell that information. Network requests to your chosen download source are described below. The app requires no account and contains no advertising, tracking, or developer-operated crash-reporting service.

Information stored on your device

Download URLs, filenames, destinations, progress, history, diagnostics, engine preferences, and security-scoped bookmarks are stored locally in the app’s sandbox. You control this information through the app and the operating system.

The browser extensions store two file-type preference lists in the current browser profile’s local extension storage. These settings control automatic download handling and are not synchronized across browsers or sent to the developer. This preference storage does not contain download URLs, browsing history, cookies, or authentication data. You can change the lists or restore their defaults in the extension’s Download settings page.

Browser extension data handling

On HTTP and HTTPS pages, the Chrome and Safari extensions locally inspect user-initiated link targets, the current page URL, an optional suggested filename, and eligible direct-download navigations or click-triggered window openings. When you choose or initiate a supported download, the extension reads website cookies matching that download URL, including authentication cookies, and obtains the browser User-Agent. It sends these with the download URL, optional filename, and source website origin to the local SDM app so the app can retrieve the selected file using your browser session. The full source page path and query are not passed to the app. Cookie values and download URLs may contain identifiers issued by the source website. The extensions do not read form input, POST request bodies, or arbitrary Authorization/custom headers. A recent-click timestamp may be held in memory for up to 30 seconds to avoid intercepting unrelated window openings; it is not retained as activity history. The extensions do not persist browsing history or send this information to a developer-operated server.

Session protection and retention

Chrome sends the handoff through an encrypted connection on your device. Safari temporarily stages an encrypted file in storage shared with the app; the app deletes it when consumed, rejects expired handoffs, and cleans up expired files on subsequent use. The custom URL scheme activates the app with a short-lived ticket and key, without embedding the cookie payload.

SDM uses browser cookies and request headers in memory for the selected download and does not save them in download history. Cookies follow domain, path, Secure, and expiration rules, including on redirects. Keep SDM running for browser-session downloads; after restarting the app, send them again from the signed-in browser. URLSession uses a foreground session for these downloads and starts a fresh transfer when resuming a paused browser-session task. Public downloads retain their normal background/resume behavior.

Network activity

When you start a download, SDM connects directly to the source you selected so it can retrieve the file. For browser-session downloads, the request includes matching cookies, the browser User-Agent, and the source origin where available. An HTTPS browser-session download cannot redirect to HTTP. The source website and your network provider may process network activity under their own terms.

Before automatically handling a candidate file link or navigation, the browser extension may send a HEAD request to the selected source to check its response headers. The browser may include matching website credentials under its cookie rules. The check does not fetch the file body, times out after three seconds, and leaves failed checks in the browser. File-type preferences apply to direct file links; the extension does not capture embedded video playback or streaming segments.

Chrome Web Store Limited Use

The Chrome extension’s use of information received from Chrome APIs adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements.

Website privacy

This website does not use analytics, advertising, tracking pixels, cookies, or externally hosted fonts. Your language and appearance preferences may be stored locally in your browser and are never transmitted by SDM. If the site is hosted by a third-party platform, that platform may process standard request logs under its own terms.

Changes

If SDM’s privacy practices change, this statement will be updated before a release containing that change is made available.

数据收集

Swifty Download Manager(SDM)不会把个人信息、浏览活动、下载链接、文件名、使用数据、分析数据或遥测信息发送给开发者,也不会出售这些信息。向你选择的下载来源发出的网络请求见下文说明。应用无需注册账户,也不包含广告、行为跟踪或由开发者运营的崩溃上报服务。

保存在设备上的信息

下载链接、文件名、保存位置、进度、历史记录、诊断信息、引擎偏好和安全作用域书签,均保存在应用沙盒内。你可以通过应用与操作系统管理这些信息。

浏览器扩展会在当前浏览器配置文件的扩展本地存储中保存两份文件类型偏好列表,用于控制自动下载处理。这些设置不会跨浏览器同步或发送给开发者。该偏好存储不包含下载链接、浏览历史、Cookie 或认证数据。你可以在扩展的 Download settings 页面修改列表或恢复默认值。

浏览器扩展的数据处理

在 HTTP 与 HTTPS 页面中,Chrome 和 Safari 扩展会在设备本地检查由用户触发的链接目标、当前页面地址、可选的建议文件名,以及符合条件的直接下载导航或点击后触发的窗口打开。当你选择或发起受支持的下载时,扩展会读取与下载地址匹配的网站 Cookie(包括登录认证 Cookie),并获取浏览器 User-Agent。扩展将这些信息与下载地址、可选文件名和来源网站的源地址(origin)交给本机 SDM,以便应用使用你的浏览器会话获取选定文件。来源页面的完整路径和查询参数不会传给应用。Cookie 值和下载地址可能包含来源网站签发的标识符。扩展不会读取表单输入、POST 请求正文或任意 Authorization/自定义请求头。为了避免拦截无关的窗口打开,扩展可能在内存中保存最近一次点击的时间戳,最长 30 秒;该信息不会作为活动历史保留。扩展不会保存浏览历史,也不会把这些信息发送到由开发者运营的服务器。

会话保护与保留期限

Chrome 通过设备上的加密连接完成交接。Safari 会在与应用共享的存储中临时写入加密文件;应用读取后删除该文件,拒绝过期交接,并在后续使用时清理过期文件。自定义 URL Scheme 仅携带短时有效的交接票据和密钥来唤起应用,不包含 Cookie 数据本身。

SDM 仅在内存中使用浏览器 Cookie 和请求头完成选定下载,不会将其写入下载历史。 Cookie 在重定向时也遵循域名、路径、Secure 和有效期规则。浏览器会话下载期间请保持 SDM 运行;重启应用后,需要从已登录的浏览器重新发送下载。 URLSession 对此类下载使用前台会话,恢复暂停任务时会重新开始传输。公开下载保留原有的后台下载与续传行为。

网络活动

当你开始下载时,SDM 会直接连接到你选择的文件来源以获取文件。浏览器会话下载会在请求中携带匹配的 Cookie、浏览器 User-Agent,以及可用的来源网站源地址。 HTTPS 浏览器会话下载不允许重定向到 HTTP。文件来源网站和你的网络服务提供商可能依据各自条款处理网络活动。

自动处理候选文件链接或导航前,浏览器扩展可能向选定来源发送 HEAD 请求以检查响应头。浏览器可能按照其 Cookie 规则携带匹配的网站凭据。检查不会获取文件正文,三秒后超时;检查失败时继续由浏览器处理。文件类型偏好适用于直接文件链接,扩展不会捕获嵌入视频播放或流媒体分片。

Chrome 应用商店有限使用要求

Chrome 扩展对通过 Chrome API 获得的信息的使用,遵循 Chrome 应用商店用户数据政策,包括其中的有限使用要求。

网站隐私

本网站不使用分析工具、广告、跟踪像素、Cookie 或外部托管字体。语言与外观偏好可能保存在你的浏览器本地,SDM 不会传输这些偏好。若网站托管在第三方平台,该平台可能依据其自身条款处理标准访问日志。

说明变更

如果 SDM 的隐私实践发生变化,我们会在包含该变化的新版本发布之前更新本说明。

Privacy should be easy to verify.
