YT2Sub - YouTube 字幕提取下载工具

Introduction This Privacy Policy describes how YT2Sub ("we", "us", or "our") handles your information when you use our browser extension (the "Extension"). We are committed to protecting your privacy. This Extension is designed to be a lightweight utility that processes data locally on your device.

Information Collection and Use

No Personal Data Collection We do not collect, store, or transmit any personally identifiable information (PII) to any external servers. We do not require user accounts, and we do not request your name, email, or contact information.
No Usage Data Collection We do not track or collect data regarding your usage of the Extension, such as which videos you view or which subtitles you download. All actions are anonymous and processed locally.
Local Data Processing All subtitle extraction and processing operations are performed locally within your browser. The content is fetched directly from YouTube's servers to your device. We do not transmit your data or the content you view to our servers or any third parties.
Usage of Permissions To provide its functionality, the Extension requires the following permissions:

Host Permissions (youtube.com): Strictly used to access the subtitle data on the YouTube video pages you visit (specifically https://www.youtube.com/*). We do not access your browsing history on any other websites.
Storage: Used exclusively to save your local preferences, such as your selected subtitle language and export format. This data resides only in your browser's local storage and is not synced to us.
Scripting: Used to inject content scripts to interact with the YouTube player and retrieve subtitle information from the current page.

Cookies and Tracking We do not use cookies, pixels, or third-party analytics tools (e.g., Google Analytics) to track your usage. We do not monitor your behavior across the web.

Data Sharing Since we do not collect personal information or usage data, we do not share, sell, or disclose any user data to third parties.

Data Security Since the Extension operates entirely locally on your device and does not collect or transmit user data to external servers, your data remains secure within your own browser environment.

Disclaimer This Extension is a third-party tool created by an independent developer. It is NOT affiliated with, endorsed by, or sponsored by YouTube or Google Inc. "YouTube" is a trademark of Google LLC. Use of this trademark is subject to Google Permissions.

Children's Privacy Our Service does not address anyone under the age of 13. We do not knowingly collect personally identifiable information from anyone under the age of 13.
