Why it is different
Other sites upload your file. This one cannot.
Not a policy, not a promise buried in a privacy page. There is simply no server on the other end to receive it.

The work happens in the tab
Your browser already knows how to read a PDF, decode an image and hash a string. These tools just ask it to. The file is opened from disk into memory and never put on the network.

Check it yourself
Open your browser devtools, switch to the Network tab, and run any tool on this site. You will not see your file go out, because it does not. Then try that on a competitor.

Turn the internet off
Load a tool once, go into aeroplane mode, and it keeps working. That is only possible because the network was never part of the job.
