KatFile - Online Video Downloader ("the extension") is a video downloading tool. We keep data handling to the minimum required to perform downloads.
When you are on a page with a video and choose to download it, the extension reads media URLs (such as HLS/m3u8 playlists and direct media files) and the request headers (Referer, Origin, User-Agent, Cookie) that your browser already uses for that page, so the download server can fetch the same media. It also reads the active tab's URL and title to identify the video.
We do not collect, store, or sell any personal information. We do not use analytics or advertising trackers, and we do not build user profiles. Your browsing history is not recorded.
The page/media URL and the headers needed for that specific download are sent to the conversion server only to produce the requested file. Converted files are stored temporarily on the server and are automatically deleted after a short retention period. Your extension settings (server address and access token) are stored locally in your browser via chrome.storage and are never shared.
Permissions (host access, webRequest, declarativeNetRequest, downloads, tabs, storage) are used solely to detect the video on the current page, set the correct request headers, and save the downloaded file. They are not used for any other purpose.
KatFile - Online Video Downloader is 100% free. It does not bundle, install, or promote any third-party software, toolbars, or extensions. It does not change your search engine, homepage, or new-tab page, and it does not inject advertising into the pages you visit. There is no hidden, deceptive, or background behavior — the extension acts only when you click to download a video.
You can remove KatFile - Online Video Downloader at any time from chrome://extensions (or your browser's Extensions page) by clicking Remove. Uninstalling deletes the locally stored settings; no leftover software remains on your computer.
KatFile - Online Video Downloader is published by the KatFile team. Official distribution site: katfile-online-video-downloader.com. The browser extension is also distributed on the Chrome Web Store.
