Amy,

If you're concerned about privacy when uploading your emails to Voyant
there are a couple things you can do.

You can set an Access Code so only people with the code can access the
data. The info is at the very bottom of the documentation on Creating a
Corpus: https://voyant-tools.org/docs/#!/guide/corpuscreator-section-xml

If you want to ensure that no one ever has access, not even the people that
run Voyant or Compute Canada, you can download Voyant and run it on your
computer. The data will never leave your computer and a local version will
run faster as well.  I don't know if you have enough emails for the speed
difference to matter, just thought I'd mention it.  Instructions for
running it locally are here: https://voyant-tools.org/docs/#!/guide/server

Good luck and let us know what you discover!

David
