The encryption code is open source as it is in the javascript so you can evaluate it. It's also available in the chrome plug-in, and there's now the app in the android play store: https://play.google.com/store/apps/details?id=com.privatesh.... so the private.sh web server or related anonymyzing proxy don't have access to your query since it is encrypted. on the gigablast servers will know your query, but they won't know your IP address.

Ok but please add anonymous view like startpage and i will recommend my friends use it. Hence startpage is owned by advertising company i cannot trust it anymore. I have only 2 options for myself private.sh or searx. I trust private.sh and gigablast. Thanks matt brother.
