This is supporte d by reports of the potential scale for online harms facilitated by the ma ss deployment of online technology and by the data-intensive web. While In ternet users often express concern about privacy\, some report taking acti ons to protect their privacy online.\n\nWe investigate the methods and tec hnologies that individuals employ to protect their privacy online. We cond uct two studies\, of N=180 and N=907\, to elicit individuals' use of priva cy methods\, within the US\, the UK and Germany. We find that non-technolo gy methods are among the most used methods in the three countries. We iden tify distinct groupings of privacy methods usage in a cluster map. The map shows that together with non-technology methods of privacy protection\, s imple privacy-enhancing technologies (PETs) that are integrated in service s\, form the most used cluster\, whereas more advanced PETs form a differe nt\, least used cluster. We further investigate user perception and reason ing for mostly using one set of PETs in a third study with N=183 participa nts. We do not find a difference in perceived competency in protecting pri vacy online between advanced and simpler PETs users. We compare use percep tions between advanced and simpler PETs and report on user reasoning for n ot using advanced PETs\, as well as support needed for potential use. This paper contributes to privacy research by eliciting use and perception of use across 43 privacy methods\, including 26 PETs across three countries a nd provides a map of PETs usage. The cluster map provides a systematic and reliable point of reference for future user-centric investigations across PETs. Overall\, this research provides a broad understanding of use and p erceptions across a collection of PETs\, and can lead to future research f or scaling use of PETs.\n LOCATION:https://researchseminars.org/talk/UK-SPS/1/ END:VEVENT END:VCALENDAR
