YouTube Caption Downloader
Privacy policy
Last updated: 3 October 2026
YouTube Caption Downloader is an independent browser extension that lets you read, copy and save captions already available on a YouTube video.
The extension has no developer-operated server, analytics, ads or account system. It requests captions directly from YouTube and does not upload your transcripts to the developer or an AI service.
Information the extension processes
On www.youtube.com, the extension reads information needed to show and export the current video's captions:
- The video title, channel name, video identifier, duration and URL.
- Available caption tracks, their languages, caption text and timing.
- Player state and temporary request information provided by YouTube to retrieve a caption track.
- Your choices within the panel, such as the selected track and whether to include timestamps.
This information is used to load the requested transcript, display it beside the video, let you jump to a timestamp, and create the copies or files you request. The extension does not request access to your general browser history or run on unrelated websites.
Requests to YouTube
Caption requests go directly to YouTube over HTTPS through your existing browser session. YouTube may therefore receive the requested video or track information and normal connection information, such as your IP address and session cookies. The extension does not ask for your Google password or send session information to the developer.
When needed, the extension may temporarily change the player's caption track or open YouTube's transcript panel. It tries to restore the previous state. An interrupted operation can leave a different caption setting; you can change it using YouTube's controls.
YouTube is a separate service. Its handling of information is covered by the Google Privacy Policy.
Storage and deletion
Loaded video and caption data, including temporary request information, is kept temporarily in the page's memory. Closing the page clears this working data. The extension does not maintain a permanent transcript library or synchronize transcripts to a developer account.
Two display preferences — whether the panel is open and whether timestamps are enabled — are kept in session storage for the current tab. Your browser may preserve a tab's session when restoring it. YouTube may separately remember caption settings in its own storage.
You can stop the extension by disabling or uninstalling it in your browser. Uninstalling does not delete files you downloaded or clear your clipboard.
Copying and downloading
Copy writes the transcript to your clipboard. Download creates a TXT, Markdown, SRT or VTT file, when that format is available, in the location managed by your browser.
These copies remain until you remove or replace them. Your operating system, clipboard manager, backup tools or cloud-synced folders may handle them separately. If you paste or upload a transcript into another service, that service's privacy terms apply. The extension does not do this for you.
