Short version: VideoGrab collects no data. There are no accounts, no analytics, no tracking, and no server that receives anything from the extension. Everything it does happens locally in your browser. Its full source code is public, so you don't have to take this page's word for it.
To find the video on a page you are watching, the extension observes media requests in your browser and reads the URLs of pages where you open it. This processing happens entirely on your device:
Files you download are saved by your browser's standard download mechanism to your own device. We never see, proxy, or store them.
siflie.com is a static site. It does not run analytics or third-party trackers. Standard server logs (IP address, user agent, timestamps) may be retained briefly by our hosting provider for security and operations, and are not used for profiling or shared for advertising.
VideoGrab is free software under the GNU General Public License v3.0. The complete source code is available at github.com/billgaohub/videograb, and you can verify that the published builds match it using the build script in the repository.
If this policy ever changes, the new version will be posted on this page with a new effective date before it takes effect. The extension's "collects nothing" design is a core feature; any future change to that would be a new product decision, announced in the release notes.
