100% Client-Side • Zero Telemetry • Open Standard

Privacy Policy

AI Music Downloader is designed with a strict "Privacy by Architecture" philosophy. We do not track, collect, or store any personal data.

Effective Date: October 22, 2026 | Version 1.1.0

Zero Personal Data Collection Guarantee

The AI Music Downloader (Suno & Douyin) Chrome extension does not collect, record, process, or sell any user information. All audio parsing and buffer extraction happen locally in your browser memory. We maintain zero remote telemetry servers.

1 Information We Do Not Collect 我们绝不收集的信息

To be unequivocally transparent with our users and Google Chrome Web Store review standards:

✓
No Personal Identity Information 无个人身份信息 We do not collect names, emails, IP addresses, physical addresses, age, or government IDs.
✓
No Accounts or Credentials 无账户密码与鉴权凭据 We never read, intercept, or store passwords, session tokens, cookies, or payment data.
✓
No Browsing History or Activity Logs 无浏览历史与行为监控 We do not log your clicks, searches, page views, keystrokes, or websites visited outside of active Suno/Douyin tabs.

2 Browser Permissions & Why They Are Needed 权限声明与合理性说明

Our extension requests only the minimum required Chrome permissions strictly necessary to download audio:

Permission	权限名	Purpose & Privacy Protection
`storage`	Saves user preferences (e.g., custom filename format `{artist} - {title}` and download subfolder name) locally on your device. Never synced to third-party servers.	在本地保存用户自定义偏好（如下载文件名模板与子目录名称）。数据仅保留在本机，绝不外发。
`downloads`	Triggers the browser's native download dialog to save converted MP3 files to your local disk.	调用浏览器原生下载接口，将转换好的 MP3 音频文件安全保存至本地文件夹。
`sidePanel`	Provides a docked sidebar UI for managing song lists and batch downloads without obscuring the active webpage.	提供 Chrome 官方侧边栏界面，方便用户在浏览网页时管理歌曲列表与批量下载。
`activeTab`	Allows temporary access to detect music generation cards when you explicitly click the extension or scan button.	仅在用户主动点击插件图标或“扫描当前页面”时，临时读取当前标签页内的音乐卡片。
`webRequest`	Analyzes audio response headers (e.g. content-type audio/mpeg) on supported music sites to identify stream bitrates.	在受支持的音乐域名下识别媒体响应头，辅助流式缓存分析，不拦截任何个人隐私流量。

3 How Audio Cache Extraction Works 播放缓存技术的工作机制

When you listen to a preview track on supported platforms (Suno AI or Douyin Music), your browser naturally buffers the audio data into local memory. Our extension hooks into HTML5 Media and MediaSource buffers to allow you to directly export that memory chunk into an MP3 file.

Key Security Factor: This conversion happens 100% offline inside your browser sandbox. No audio fragments are ever transmitted to any third-party infrastructure.

4 Third-Party Sharing & Sale of Data 第三方共享与数据出售

We adhere to the Chrome Web Store Developer Program Policies:

✓
No Selling of Data 绝不出售数据 We do not sell, rent, or monetize user data to data brokers, advertisers, or third parties under any circumstances.
✓
No Unrelated Transfers 绝不转用于无关目的 Data is not used or transferred for purposes unrelated to the single purpose of downloading music.
✓
No Credit or Lending Evaluation 绝不用于信用评估或借贷 We never evaluate creditworthiness or financial conditions.

5 Children's Privacy & Security 未成年人隐私与安全保障

Because AI Music Downloader collects no information whatsoever, we do not knowingly collect or solicit personal information from children under the age of 13.
