Structured Abstract ------------------- **Background.** Incidental emotions users feel during their online activities may alter their general stance on privacy behavioral intentions. **Aim.** The aim of this study is to investigate to what extent an incidental affect state of induced happiness or fear causes differences in privacy behavioral intention. **Method.** In a within-subjects random-controlled trial, $N=60$ participants (in the lab and on MTurk each) are exposed to either a neutral state video, or---in randomly assigned order---standardized stimulus videos inducing happiness or fear. As manipulation check, we measure the affect present in that moment with the Positive and Negative Affect Schedule (PANAS-X, 15-item version on fear and joviality) and in the lab with affect recognition on face geometry from a video recording. We evaluate the mean difference of Privacy Behavioral Intention (PBI) across fear and happiness conditions as well as a linear regression on reported fear and joviality on PBI. **Anticipated Results.** We will obtain the results of dependent-samples $t$-tests and OLS linear regressions on the impact of affect on privacy behavioral intention, in addition to results on the manipulation check on the strength of the induced affect. **Anticipated Conclusions.** We expect to learn how a current affect, even if it is incidental, that is, unrelated to the task at hand, influences privacy behavioral intention.
