StockSilo Privacy Policy
Last updated: July 13, 2026
StockSilo is a browser extension (Chrome and Firefox) that helps Video Editors and Producers keep track of stock footage comp downloads, and — where the browser allows it — organizes those downloads into folders.
The short version: StockSilo does not collect, transmit, sell, or share any data. Everything it does happens entirely on your computer.
What StockSilo processes, and where it stays: Download details (file names and the addresses of pages you download from on stock footage sites), written to a log file (a CSV) either inside your Downloads folder (Chrome) or wherever your browser's own download settings place it (Firefox). Your settings (project names, tracked-site list, folder name preferences), stored in the extension's local browser storage. Links on stock footage site pages: at the moment you download a comp, StockSilo may read the address of that clip's page from the site you are viewing, so your log can record the specific clip rather than a generic search page. It reads link addresses only — it does not read, modify, or store page content.
None of this information ever leaves your computer. StockSilo has no servers, no analytics, no accounts, and makes no network requests.
Permissions: StockSilo requests access to certain stock footage websites solely to read clip page links at download time, as described above. When you choose to track an additional site, your browser asks for your permission for that specific site; declining does not affect any other feature.
Chrome vs. Firefox: The information StockSilo processes is identical on both browsers. The only difference is what each browser lets an extension do with a download's file location: on Chrome, StockSilo can file comps into organized folders; Firefox doesn't provide that capability to extensions, so on Firefox everything is fully logged but saved wherever your normal Firefox download settings send it.
Data removal: Uninstalling the extension removes all of its stored settings and log data from your browser. The CSV files and downloaded footage on your computer are ordinary files that you control and can delete at any time.
