Enock Samuel Mbewe. I am currently a Computer Science PhD candidate at the
University of Cape Town, South Africa. I am conducting an evaluative study as
part of my research project. This is an output (artefact) of the study you participated in
2020; therefore, it makes sense that you be the one to evaluate it also. This
tool enables Internet users to easily configure security and privacy, which are
currently hidden for an average Internet user. The feedback from this
evaluative study will help improve the app to respond fully to user needs in a
quest to improve the security landscape of cyberspace. Therefore, I believe
that your views and experience would be a valuable source of information, and I
hope that by participating, you will gain helpful knowledge. <span></span></span></p>
