How it works

Your file is handled by a tool that runs on a different website from the page you are reading. The page you are reading has ads. The tool's site does not, and cannot be read by the ads.

What the automated checks prove

• During a job, the tool makes no network requests except for its own files.
• The page you are reading cannot read the tool's contents, and gets no file names, sizes or hashes.
• The tool's site refuses to be shown on any other site, and opens on its own only by redirecting here.

What they do not prove

• A browser extension that reads every page you visit, or a compromised computer.
• An ad that replaces the tool with a fake one. Our protection is the ad network's policies and monitoring.

Check it yourself: open the browser's network panel, run a job, and watch which addresses it contacts. The tool's own address is the only one it should use.
