Why &ldquo;privacy-first&rdquo; is literal here

Most online converters upload your PDF or spreadsheet to a server, run the<br>job there, and hand back a link. ToolsNow does the work in the page you<br>already have open — the file never leaves your machine, so there is<br>nothing for us to store, log or lose.
